This tutorial takes y'all through the steps of setting up your own Java Edition server using the default server software that Mojang Studios distributes free of charge. The software may be installed on near operating systems, including Windows, macOS, GNU/Linux and BSD.

For more tutorials, see the bottom of this folio or the Tutorials page. For more information on Minecraft servers, see the Server page.

Notes:

  • Setting up a server takes some time, and some technical knowledge. Don't attempt to set up a server unless you have some basic reckoner and networking abilities. Probably, your best bet can be to await on the Internet for a guide on how to prepare a server.
  • A Minecraft server does non demand to be a high-end machine, only netbooks and notebooks don't unremarkably make for good server machines. They typically have lower-cease hardware and bad I/O performance in comparison to desktop computers.
  • Hosting and playing on the same auto is also possible, if your reckoner is powerful enough.
  • Having many players in a wireless network (WLAN and especially WWAN) is not recommended. Use a wired network instead, such as Ethernet.
  • If yous make up one's mind you don't want to host, but still want to play online, check out the public server options on a Minecraft server listing website.
  • If you withal want to manage a server, but not from dwelling, bank check out the Minecraft server hosting area of the Minecraft Forum or other websites. Expect to pay monthly for this type of server since finding free hosting is a rarity, but you save the hassle of constantly maintaining a server and ensure information technology is always online for your players.

Note: There is besides custom server software available, which most large servers employ, merely these applications are not supported past Mojang Studios.

Warning

Note

Running server software on your computer without a clear understanding of what you are doing may brand your system vulnerable to attacks from outside.

Since you're nearly to run your ain server, you should be aware of the possible dangers. Running by the instructions beneath should not put yous at whatever risk, but this is a wiki which everybody is allowed to edit, and we don't know nearly your organization configuration, then we can't guarantee yous'll exist 100% out of danger.

In order to run your server and stay out of trouble, we highly advise that y'all should at least know about the following:

  • Using the control-line and editing configuration files
  • Networking in full general (IP, DHCP, ports, etc.)
  • Your organisation configuration
  • Your network configuration
  • Your router configuration (if you lot desire other people to connect over the Net)

Coffee

Coffee is a programming language designed to create programs for the Java Virtual Machine (JVM). The JVM supports many different platforms. By doing this, developers write code for the JVM and whatsoever platform supported by the JVM tin can run the programme. Further reading.

This department is designed to answer some frequently asked questions nigh Java and guide you through some decisions regarding Java.

OpenJDK vs OracleJDK

OpenJDK and OracleJDK are very similar. OpenJDK is the official open source reference implementation of Java. OpenJDK is an open source codebase that near all other JDKs are built on. Excluding packaging, corrective and license differences OpenJDK is the aforementioned every bit OracleJDK.

Do note that OracleJDK (Oracle's "OTN") builds require a paid subscription for commercial and product purposes. This probable includes running a Minecraft server even if information technology is non-profit. Oracle does provide its own OpenJDK builds, but they are non packed into an installer format for easy use.

JRE vs JDK

JRE correspond Java Runtime Eastwardnvironment. JDK stands for Java Development Kit. JRE is a packet tool designed to run Java programs. JDK is a packet of tools designed to develop Coffee programs. The JDK comes with the JRE which comes with the JVM. If you have JDK then you lot accept JRE and JVM. Vanilla Minecraft does not need JDK, simply plugins may require information technology.

Headless Java

A headless Coffee installation is a trimmed downwardly version of Coffee. Information technology does not take a GUI or mouse/keyboard support. Headless Java is often used in Servers or other environments where a GUI is not needed.

"

There are several virtual packages used in Debian for Java. These encompass runtime compatibility and come in two flavors; headless (omits graphical interfaces) and normal.

Debian Wiki

Common instructions

The general gist of running a Minecraft server is that you lot will demand to install java, run the server, take the EULA, and run it once more. Once you take installed java and opened up a control line, everything is basically the aforementioned.

  • Check the system requirements for CPU, RAM, and disk space.
  • Install Java. Use the OS-specific instructions beneath for this.
  • Download your server jar file from the download page.
  • Make a new folder for the jar file and move it at that place. This will be where all the configuration and the world files will be stored, so you don't desire these to just sit down in "Downloads".
  • Open a command prompt or a terminal interface. (On windows: search for cmd. On macOS: open terminal in launchpad."
  • Check over again if Java is available. Type java -version.
  • Blazon cd (modify directory), followed by the path to the binder where you lot placed your server jar file. You can drag the binder into the terminal window to get the path, if you take a GUI open.
  • Run the server for the showtime time by typing coffee -jar minecraft_server.jar --nogui (replacing the jar proper name (minecraft_server.jar in this case) by whatever you named the jar file to exist).
  • A file called eula.txt volition exist generated subsequently you run the server for the first time. Open it in a text editor and change eula=false to eula=true. It signifies that you have read and understood the end user license understanding that you'll follow when using the software. If you don't do this, the server will shut down immediately when you try to start it.
  • Now the server has been set up, and yous can simply run it with java -jar minecraft_server.jar. If you don't desire a GUI for typing commands, add a space and --nogui to the command. (Some people say information technology makes the server much much faster.) You lot can besides use a few other switches described beneath.

At this point you should have a basic server running. Meet Configuring the environment for more than information virtually configuring your server. One of the things you definitely desire to practise is writing a script to launch the server so you don't have to remember the command line.

Java options

Java options should be added between the java and the -jar on the command line, or in your startup script.

  • The nigh important thing for a Minecraft server is memory to run with. Employ the -Xmx switch to change how much memory it's allowed to use. -Xmx4G (ii gigabytes) is usually more enough.
    • -Xms (the initial retention size) does non bear on operation in the long run, but you lot can prepare information technology too. -Xms512M should be enough.
      • When coffee changes the heap size, it slows down operation, so it is recommended to set -Xmx and -Xms to the same value, for example command: java -Xmx4G -Xms4G ( ... your other coffee options) -jar ( the name of your server jar, for example server.jar) (your minecraft options)
      • This would run the server with 4 gigabytes of RAM.
    • A "soft max heap size" (-20:SoftMaxHeapSize=1G) is bachelor for some versions of JRE. The JRE will try to only use that much memory, only will get over to a maximum of -Xmx if necessary. If you are running many things on your server, this may be useful.
  • Employ -d64 if your server is on a 64-bit Solaris organization using 64-bit Java.
  • For optimal functioning, use Aikar'due south flags as your Java options. These flags are mostly accepted as the way to get the best, stable operation.

Minecraft options

Options for the server JAR go after the -jar minecraft_server.jar part. Run with --assist to come across all available arguments that tin be passed to the server. Below is a list of available commandline options for the server.

  • --bonusChest
    • If a bonus chest should be generated, when the world is start generated.
  • --demo
    • If the server is in demo manner. (Shows the players a demo pop-upward, and players cannot intermission or place blocks or eat if the demo fourth dimension has expired)
    • Equivalent to playing minecraft without a account, you have virtually 5 in-game days before your trial ends.
  • --eraseCache
    • Erases the lighting caches, etc. Aforementioned option equally when optimizing single histrion worlds.
  • --forceUpgrade
    • Forces upgrade on all the chunks, such that the data version of all chunks matches the current server version (same as with sp worlds).
    • This option significantly increases the time needed to start the server.
  • --help
    • Shows this assist.
  • --initSettings
    • Loads the settings from 'server.backdrop' and 'eula.txt', then quits.
  • --jfrprofile
    • Initializes the Java Flying Recorder on the server. Only available on 1.xviii+.
  • --nogui
    • Doesn't open the GUI when launching the server.
    • You volition yet be able to collaborate with your server, but you must use the cmd or Terminal if enabled.
    • nogui does the same thing equally this option for backwards compatibility with very one-time versions of the server, simply --nogui is preferable equally it matches the format of other options
  • --port <Integer>
    • Which port to listen on, overrides the server.backdrop value. (default: -1, read from server.properties)
    • See Server.properties for restrictions on this value.
  • --safeMode
    • Loads level with vanilla datapack only.
  • --serverId <String>
    • Gives an ID to the server. (??)
    • Seemingly no event ??
  • --singleplayer <Cord>
    • Runs the server in offline fashion (unknown where <Cord> is used for, probably used internally past mojang?)
  • --universe <String>
    • The folder in which to look for world folders. (default: .)
  • --world <String>
    • The proper name of the world folder in which the level.dat resides.
Older Commandline Options

Some options worked in older versions but were removed or replaced by newer ones.

  • -o truthful
    • to tell the server to run in online manner and then only authenticated users tin can bring together. (This may no longer work in newer versions)

Case command line

  • Running a world establish in the folder "cold" on port 1337, with 1G of RAM immune: java -Xmx1G -jar minecraft_server.jar --port 1337 --nogui --earth common cold.

Windows instructions

Installing Java

The Minecraft server requires the Java Runtime Environment (besides called JRE or but Java). For your security, you should only use the most contempo version of Java. To verify that yous take the latest version, practise 1 of the post-obit:

  • Open Windows Control Console, find Coffee (it may be inside the Programs category), and click on Update Now.
  • Visit http://java.com/en/download/installed.jsp. This will perform an automatic version check from your browser. However, the Google Chrome and Firefox browsers practice not run Java content and therefore cannot bank check Java through the browser.
  • Open up a control window and enter the command java -version. If a version number is reported, so cheque the Java website to see what the most recent version number is.

If you don't have Java or your version is outdated, so download it at https://adoptopenjdk.net/ (OpenJDK) or http://www.java.com/download/ (Oracle "OTN" JDK)

macOS instructions

Go along in heed that the server won't run correctly on macOS 10.4 and earlier and may crash your machine.

Installing Java

Open the terminal.

  • Check if yous have java by running java -version. Make certain information technology'south newer than i.6 (all-time if newer than 1.8), for most versions, or java 17+ on 1.17 & one.18.
  • If y'all don't have java, yous tin can install it via HomeBrew:
    • Run /bin/bash -c "$(gyre -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" to install HomeBrew get-go.
    • Run brew install openjdk to install java (OpenJDK).
  • Run java -version once more. You should go something this time.

Setting upward the Minecraft server

Come across the Common instructions.

Using Fourth dimension Capsule

Some homes apply Airdrome Time Capsule as a wireless router instead of other brands. This department will teach you how to set one up without messing up your file server.

Notation: Make sure you have your admin username and countersign.

  • Open Arrangement Preferences > Network.
  • Click the Advanced button and go under TCP/IP.
  • Where it says Configure IPv4, change that option to Using DHCP with manual address.
  • Change the IP accost to 10.0.ane.x, where 10 is a number between the last number of the two numbers nether DHCP range (i.e. 10.0.1.two to 10.0.1.254 would be anywhere betwixt 2 and 254).
  • Now become to the Sharing section and make certain that Internet Sharing is on.
  • Now, open upward Airdrome Utility and edit your Time Capsule settings.
  • Go under Network and make sure the option Router Mode is set to DHCP and NAT. Now, click the + button under the Port Settings.
  • Type in the following:
    • Clarification: Minecraft Server (or any you desire to call it)
    • Private IP Accost: The address yous chose for the fourth step.
  • Change everything with the word port in it to 25565.
  • Now, hit Save and update the Time Sheathing.

That'due south it! Y'all're at present ready to configure your server.

Linux instructions

Linux comes in many dissimilar varieties called distributions (distros). Some of these distros are designed or better suited for running a server. If you are setting up a defended server it is recommended to apply ane of these distros.

Linux, in general, is more welcoming to open up source programs. So where applicative information technology is recommended you utilise open up source programs, such as OpenJDK.

Installing Java

For most distributions, information technology is recommended to install OpenJDK 16 (for i.17+) or OpenJDK 8 (for below 1.17) from the official repositories. For Oracle Java refer to Oracle's Download Folio.

Notation: While not affecting Minecraft server, JavaFX or other proprietary aspects of Java while need to be installed separately.

Specific instructions are included for each distro below, but not all have been updated to 1.17. If it only says to install OpenJDK viii, that means that it has not yet been updated to 1.17.

Solus

Run sudo eopkg install openjdk-8 to install OpenJDK.

For OracleJDK refer to Solus Help Middle

Note: OpenJDK eleven is not in Solus' repositories.

Debian, Ubuntu, Raspbian

Annotation: You might need to install the package "software-properties-common" past running sudo apt-get install software-properties-mutual and/or "python-software-properties" past running sudo apt-get install python-software-properties to employ the apt-add-repository command.

Due to licensing issues, the repository frequently used to install Oracle Java has been discontinued. Information technology is at present recommended that you lot install OpenJDK eight or to a higher place.

OpenJDK can be installed with one command:

  • sudo apt update; sudo apt-get install openjdk-8-jdk-headless below Minecraft Server 1.17
  • sudo apt update; sudo apt install openjdk-sixteen-jdk-headless at or in a higher place Minecraft Server 1.17

Removing the 'headless' office of the command will install all components of Coffee.

Note: <i.17 tested in Ubuntu 18.04, 1.17 tested in Ubuntu Server 20.04.ii LTS

openSUSE

Notation: Due to possible instability openSuse Tumbleweed is non recommended as a dedicated server.

Just run the command from the terminal: sudo zypper in coffee-1_8_0-openjdk

Java should be installed.

Annotation: Tested in openSuse Leap xv.1

Arch Linux

Both coffee eight and 16 are in arch linux's repostiory.

But run pacman -S jre-openjdk-headless, For the OpenJDK 16 JRE, Remove "-headless" for the full JRE if you desire to run with GUI.

Just run pacman -South jre8-openjdk-headless, For the OpenJDK eight JRE, Remove "-headless" for the full JRE if you lot want to run with GUI.

If you encounter issues it is recommended that you lot refer to the ArchWiki

Gentoo

Run emerge --ask virtual/jdk

Gentoo Wiki

Other distros

Check your distro's documentation. It should have information on how to install OpenJDK.

Alternatively, you can visit Java's website straight to download the Java package for Linux. About distros work with this (either 32 or 64-flake). Instructions for the installation of those different packages are given on the site.

If during installation, it asks for a password, enter your password. If you go asked "Is this OK [Y/Northward]" Enter Y and printing enter if required. Java should at present be installed.

Note: this is a very early projection, designed with offline installation in mind, and will be updated periodically to go far more user friendly.

FreeBSD instructions

Clock JE3 BE3.gif

This section needs to be updated.

Please update this section to reverberate recent updates or newly available information.
Reason: The official people have been using Coffee 8 for quite a while, so Java 7 is definitely outdated. A lot of the crashing is gone with OpenJDK8, so maybe the whole Linux-compat affair tin be removed once tested.

This part was tested with FreeBSD 10.0 amd64 and 'jre-7u65-linux-i586.tar.gz'

Installing Java

Due to performance and crash issue with OpenJDK and Minecraft server, we will install Oracle JRE fabricated for linux.

Earlier installing this JRE, you take to install the linux binary compatibility on FreeBSD, you can follow this documentation.
Jave requires some information nigh the proc. You have to mountain linprocfs, type:

            kldload linprocfs mount -t linprocfs linprocfs /compat/linux/proc          

and add together this line to /etc/fstab:

linprocfs   /compat/linux/proc   linprocfs   rw   0  0        

The Oracle JRE has a dependency marked as forbidden and the installation volition neglect. Go to /usr/ports/textproc/linux-f10-expat2.0.one/ and in the Makefile remove the line which starts with FORBIDDEN=.

Next you lot have to manually get the linux tarball due to licence upshot (like `jre-7u65-linux-i586.tar.gz') from java official web site and copy the file to /usr/ports/distfiles. Then to install the JRE, become to /usr/ports/java/linux-sunday-jre17/ and run make install distclean.

Note: The previous version of this function, tested on FreeBSD 9.2 amd64, was explained like this: You may take to ready JRE_UPDATE_VERSION variable in your Makefile to the actual number (east.one thousand. 45 like in this case) and run 'make install NO_CHECKSUM=1'.

Attempt running java -version. You lot may end up with a bulletin that it cannot find libjli.so. One fashion to fix it is to add together your java paths to the search explicitly. Brand a symlink:

            ln -s /usr/local/linux-sun-jre1.7.0/lib/i386 /compat/linux/usr/lib/java          

And in /compat/linux/etc/ld.and so.conf.d/coffee.conf add:

/usr/lib/java /usr/lib/coffee/jli        

Run /compat/linux/sbin/ldconfig. Now coffee -version should work.

Launching Minecraft Server

Create a folder and copy the Minecraft server jar in information technology.
In the actual version you will get this exception syscall epoll_create not implemented if you run the server in the usual way, then we add together this line to the control to fix that -Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.PollSelectorProvider.
The control to launch is similar:

            coffee -Xmx1024M -Xms1024M -Djava.nio.channels.spi.SelectorProvider=dominicus.nio.ch.PollSelectorProvider -jar minecraft_server.ane.7.10.jar --nogui          

Plan nine

conflicting-convert PATH_TO_YOUR_JRE.deb chmod ~/~ rwx # for electric current user snarf java -jar PATH_TO_SERVER_JAR.jar xvmf in pinnacle        

Hostman

Hostman is an application hosting provider to host apps in the deject. Minecraft is available as a 1-click app package on Hostman. Installation takes about ii minutes, there'due south an didactics on how to configure the server and first playing. You can have multiple Minecraft services on ane server. Effort a costless demo hither.

Cloudron

Cloudron is a platform to self-host apps on your server. Minecraft is bachelor every bit a one click app on Cloudron. It comes with a web interface to manage Minecraft from the browser. Y'all can also have multiple installations of Minecraft on the aforementioned server. You can try a demo here (username: cloudron password: cloudron)

Docker

Docker is a free container based platform which helps to isolate instances of a Minecraft Server from each-other and from the host system. Docker and the owner of the repository of the container are non affiliated with Mojang.

Getting docker (for Linux, Mac & Windows)

Read https://docs.docker.com/install/

Docker image

  1. Download the image by running docker pull sirplexus/minecraft-server-standalone:latest
  2. Set the container with port 25565 open, 1G ram assigned and named "MyServer": docker container create --publish 25565:25565/tcp --name "MyServer" --env RAM =1G sirplexus/minecraft-server-standalone
  3. Start the container: docker container start MyServer

Updating Docker image

For updating minecraft-server-standalone run

            docker pull sirplexus/minecraft-server-standalone:latest          

Docker-Minecraft on Synology diskstation

Annotation: This is for self-hosted worlds NOT a standalone. You will need to download a server.jar for the official site.

Docker is an "Add together-on Packages" on many new Synology Diskstations, and many of them are powerful enough to run at to the lowest degree 1 Docker Minecraft.

Before starting the docker, you demand to make a folder containing the version of Minecraft you would like to play (It has to be named "server.jar") and an eula.txt (read virtually this under "Mutual instructions").

The way to setup a Minecraft server on a Synology Diskstation is to:

  1. Install and open docker on your Diskstation
  2. Search for "sirplexus" under Registry and discover "sirplexus/minecraft-server". Right click and "Download this prototype".
  3. After download you can discover the epitome under image. Printing "Laungh"
  4. Press "Avant-garde settings" and go to the tab "Volume". Add the previus created binder and fix "mound path" to "/srv/minecraft".
  5. Go to the tab "Port Settings" and assign a "Local Port". This is the port you will connect to from the Minecraft Launcher.
  6. Printing "Apply" and "Next" and again "Apply" to finish the container.

You will now exist able to play Minecraft on your Synology Diskstation. The IP address it the IP of the Diskstation and the Port number is assigned undet step 5.

Configuring the environment

Writing a script to launch the server

It'due south definitely boring to have to remember the command-line options for your server every time yous launch it. Luckily, we can write it down in a file and but run that instead.

On Windows

The windows version of a script is called a batch file. Create a text file in the folder where y'all put the jar every bit "showtime.bat", and then right click it to edit using notepad. Paste the following in:

                        @            ECHO            OFF java -Xms1024M -Xmx2048M -jar minecraft_server.jar --nogui            suspension          

Double click the file to get-go your server. You may go a "Class_Not_Found" and ServerGuiConcole error, simply ignore these errors and you should see your "Server Thread/INFO" dialog start the server.

The "suspension" command is at that place to proceed the window open then you can read what happened later the server stops.

On macOS, Linux, and FreeBSD

All these systems use a common scripting language called the "POSIX vanquish script" on the command line. Create a text file in the folder where you put the jar every bit "start.sh" and write the following in:

                        #!/bin/sh            cd            "            $(dirname            "            $0            "            )            "            exec            java -Xms1G -Xmx1G -jar server.jar --nogui          

Now salvage the file. Run chmod a+x start.sh (or path to wherever you put the script) to make it executable. You can now run the file by double-clicking or past running ./get-go.sh in the binder (or using a whole path from outside there).

If you want to add together a pausing part like the Windows example, remove the exec word, and add a line of read -due north 1 -p "Waiting..." to the end. This is useful if you are running the script by double-clicking on the GUI.

On Program 9

(I don't use Programme nine, so I have admittedly no idea how to use the rc, psh, superlative, snarf magic. Someone please add it.)

Startup and maintenance script

Alternatively, you can manage/automate the startup and shutdown of the Minecraft server using a script such as the ones listed below:

  • Minecraft Server Control Script (MSCS) is a server-management script for UNIX and Linux powered Minecraft servers. Features include:
    • Run multiple Minecraft worlds.
    • Starting time, cease, and restart single or multiple worlds.
    • Create, delete, disable, and enable worlds.
    • Includes support for additional server types: Forge, BungeeCord, SpigotMC, etc.
    • Automatically fill-in worlds, remove backups older than X days, and restart worlds.
    • Visit the Minecraft Server Control Script Github page for more information.
  • Minecraft Server Manager A comprehensive startup script for Minecraft and Bukkit servers (support Debian, such as Ubuntu).
    • MSM tin can too periodically create World Edit compatible backups.
    • Keeps players informed with configurable in-game messages, such as "Shutting downwards in ten seconds!"
    • Expose in-game commands (such equally "say", "op" and "whitelist") to the terminal.
    • Tab completion on all commands makes learning piece of cake.
    • Visit Minecraft Server Managing director'south GitHub page for the full list of features.
  • Server startup script
  • FreeBSD startup script
  • OpenBSD startup script
  • Ubuntu startup script
  • rfwadmin startup script with web interface (for Linux servers). Nice web interface for quickly saving and loading maps.
  • Minecraft Systemd Service A fully systemd-integrated Minecraft service:
    • Working on CentOS and Fedora
    • Protecting the server with various readonly and inaccessible jails
    • Safe restart and stop operations using rcon
    • Can exist combined with a Minecraft Command Middle Script for ease of administration
  • Arch Linux systemd wrapper

Port forwarding

Port forwarding is used when you have a router and you wish to allow users connect to your server through information technology. If you lot wish to host your server for local reasons, it is not required that you do and then. Keep in mind that port forwarding might cause security risks.

When port forwarding, it varies on how your router will ask you for the data. If yous don't understand on how your router wants y'all to input the data, endeavor visiting PortForward.com for a tutorial.

Once you have managed to locate your router's admin folio, and discover the Port Forwarding folio; hit add new service (may not work) (if you utilize Belkin, this tin can be very difficult to perform) or custom service. When yous get a folio asking to setup the new dominion, it should prompt yous on what you want to call it. You lot may name it as you wish, but for simplicity, name it "minecraft". Then, you want to look for "type". If "TCP/UDP" or "Both" isn't an option you lot will have to create two rules for both protocols. For the ports (internal and external), enter 25565. If it asks for annihilation else other than output IP (or internal IP, server IP), go out it solitary and continue.

To find your computer's IP address, use the following steps:

Windows Windows
Press ⊞ Win +R; this should be up to the "Run" dialog box. Blazon cmd and hit ↵ Enter. This should open up a control window with a black background. From in that location, type ipconfig and printing ↵ Enter. You should be given a list of text. Scroll up to "Wireless LAN" (if using wireless) or "Ethernet" (if using a wired connection), and look at "IPv4 accost". To the right of this should be a string of numbers (of the form xxx.xxx.30.xxx). Re-create this down by correct-clicking the window and selecting "Mark", then highlight the area and hit Enter. Don't copy any parentheses or messages.

The IP location on Bone Ten

macOSMac
Locate your way to your desktop. Pull upwardly the apple tree menu under the logo and scroll down to System Preferences; then select "Network" your IP should be on the lower right as "IP address (xxx.thirty.30.xxx)". Once you have your IP, re-create it down.
LinuxLinux
Either you use the network diagnose centre (depending on distribution), or the concluding with ifconfig. The output should return all your interfaces. Search for inet addr:30.xxx.xxx.thirty, copy the thirty.xxx.xxx.xxx numbers down.
Once you have this IP, enter it in the "Output IP / Server IP" or whatever mode it asks for where the service points to.
One time you have completed information technology, find where it says to save/continue/apply. And you have successfully port forwarded. When you run your Minecraft server, y'all take to leave the Server IP field empty in the server properties.
For people to connect to your server, they must use your external IP, which you can find at websites such as IP Chicken. If you don't want to use such IPs, employ DynDNS services such as NoIP DynDNS

Now it is time to configure and connect.

Setting upwards a VPN

Annotation

VPN'due south can cause issues connecting to Mojang's servers, Minecraft servers, or to the internet.

Paper JE2 BE2.png

An alternate way to set up a server betwixt you and your friends is to set up a VPN (virtual individual network). This method may be deemed unrecommended, and an inconvenience for many users due to the fact that all users who wish to connect to the server must download external software in order to bring together or create server. An alternative to this method is to port forward. A free software utility that tin be used to set up upward a VPN is Hamachi by LogMeIn. OpenVPN is some other (free, open source) alternative that supports virtually OSes, but is a bit more difficult to configure. Free Radmin VPN is some other software with no demand to register on the website and no limits per the number of users. The free version of Hamachi allows up to v connections (i.e. players).

Setting up Hamachi

  1. Install Hamachi on each computer that wishes to participate in the server, including the host.
    Windows / Mac
    Linux (32-bit and 64-chip .deb and .rpm packages are available, you can install it on Gentoo by emerging "net-misc/logmein-hamachi")
  2. The host server signs upwardly for admin via the Logmein website.
  3. On the host motorcar, a new Hamachi network is created.
  4. The host installs and configures the Minecraft server software:
    The server IP field in server.properties is left blank (equally default).
  5. The host passes the newly created Hamachi network credentials to each of the players.
  6. The players connect to the host's Hamachi network.
  7. Now that all the machines are connected within the same Hamachi network, the host gives their machine's Hamachi IPv4 address to the players.
  8. Each player connects using this IP as per the usual Minecraft multiplayer screen.
  9. Notation that Hamachi has been squatting on an IANA-allocated IP block (25.0.0.0/8). Every bit such, Hamachi fundamentally conflicts with the internet itself.

Setting upward Radmin VPN

It is very similar to Hamachi installation.

  1. Download free and install Radmin VPN
  2. Create a network: afterward Radmin VPN installation on the local computer printing "Create network" button. Ready a Network name and a Password —> Press "Create" button.
  3. Now the new network will appear in the main window —> invite friends, send them the info to connect -> you are welcome to run Minecraft.
  4. Connection: after program launch press "Bring together network" —> in the dialog box press enter Network name and Password received from the network ambassador —> "Join" —> the new network and its nodes will be shown in the main window. —> Connect to the host in Minecraft.
  • If the connection on Radmin VPN has been established, merely yous don`t see other players in the game, and then it is required to suit firewall for work of the game or just turn the firewall off.

Configuring the Minecraft server

  1. Configure the server past editing the server.properties file, the format for which is explained hither. Exist certain to edit the file with a text editor that does not add formatting (e.g., for italics), such equally Windows Notepad. Additional configuration may not be necessary as many servers run fine from the default values.
  2. To become or add an operator (op), type /op <targets> into the server console or gui. This adds the specified user'south username and UUID to the ops.json file. Operator status will not exist changed if yous alter your username due to the use of UUID.
    • Administrators and operators may execute commands. In other words, operator (op) privileges permit you to control certain aspects of the game (east.g., teleporting players).
    • ops.json contents:
                        [            {            "uuid"            :            ""            ,            "proper noun"            :            ""            ,            "level"            :            iv            ,            "bypassesPlayerLimit"            :            false            }            ]          
  1. If your server.properties is configured to enable whitelist, you can add a user to the whitelist.json by typing /whitelist add together <role player> into the server panel or gui. Due to the transition to the UUID system, it is not recommended to directly edit whitelist.json.

Connecting to the Minecraft server

  • If you are playing on the same machine on which the server is running, select the "Multiplayer" option in the game client, click straight connect, and so blazon in localhost instead of an IP address.
    • Both hosting and playing on the same automobile is not a recommended practice unless you have a powerful computer (due east.g. more than than 6 gigabytes of ram (4 for the server, 2 for the customer, and some for the rest of the system).
  • Users inside your local network (i.e., that are accessing the same router) tin connect using your internal IP accost; port forwarding is not required for such local connections. The internal IP address of a specific network adapter can exist found by typing "ipconfig" into the command prompt and looking for the IPv4 address, or past using this website. If the port is set to a number other than 25565 in server.backdrop, that port must be included. This address (both IP and port) will look something similar 192.168.0.168:25565.
  • Users connecting from the Net (i.due east., outside of your local network) must connect using your external IP address. You must port forward for someone outside your network to connect to the server.

IP address notes

  • Unless y'all set a static IP for the computer that is hosting the game, the internal IP address tin can change. This affects port forwarding rules, and tin make them invalid. Each modem or router has a different way of setting a static IP accost. You should refer to the manual for your device(s) or online documentation for further instruction.
  • If yous are having players connect to your external IP, your external IP tin change if you do not have a static IP from your cyberspace service provider. Apply a tool such equally WanIP to periodically cheque on the external IP accost. You may also search "my ip address" on Google and it will prove your IP address. Alternatively, y'all tin await into a DDNS service that volition allow you to have a proper name, rather than an IP address, that volition remain the aforementioned. The proper name will point to your external IP address, regardless of whether or not information technology changes (the DNS is updated when changes occur, hence "dynamic").
  • For troubleshooting purposes you lot can attempt running Minecraft on the server machine and connect locally. Yous can connect through either localhost, your home network IP (192.168.x.x) or your public (Internet) IP.
  • If for some reason you take problem with connecting publicly over your IPv4, try connecting over IPv6. This should only be done for testing whether your server is online, external players should nevertheless utilize IPv4.

Firewalling, NATs and external IP addresses

  • Yous must open up a TCP/UDP port (default is 25565) on the firewall.
    • If the server in question is not reachable via a globally routable IP accost, you volition need to add appropriate accost and/or port number translation rules to the gateway — usually your router has the global IP address.
  • For help with address translation, opening the firewall and routing (these three brand up what people call port mapping/forwarding), portforward.com is a expert source. Select your router from that list, skip the ad that comes after selecting the device, and you lot will see instructions for setting upward port forwarding. Alternatively, yous can read the documentation supplied with your router, modem, or other Internet service provider related hardware.
  • Verify the port is open up, and annotation your external IP by using a port checker tool, such as You Get Betoken. The default port you should test is 25565, unless y'all specified something else. Have the Minecraft server running when you examination the port.
  • Yous can obtain your external IP address from YouGetSignal.

Local network dedicated servers

This only applies to Classic (v0.30) servers.

A common trouble for server administrators is the inability to connect to your own server via another car on your local network. A typical scenario for this is that yous have a Classic server running on a dedicated machine, and you have your own machine which you play on. They're both connected to the same router/switch, and have internal IP'due south with the octets '192.168.10.ten'. Normally, connecting via the URL generated for your server will event in an error message challenge that the server is offline.

To correct this, you must add together a function to the stop of your URL, bookmarks, or whatsoever else you connect by. The office is: ?override=truthful
Example: http://world wide web.minecraft.net/classic/play/4c3bebb1a01816acbe31c5ece1570da5?override=true

Previously, (before the 1.8 beta and website update) this was &override=true. This caused much confusion since the modify was not announced by Mojang, and wasn't announced on the website applet pages either. Before the update, connecting to your own URL via the website resulted in cherry-red text under the applet window saying "If you tin can't connect, try this link instead." The link returned the same thing, with the &override=true affixed to the end.

Note: This situation does not issue Beta servers, and you lot should be able to connect via an internal or external IP.

The SRV record

Coffee edition since 1.iii also supports using custom ports without requiring the role player to type information technology. This is achieved by using a SRV record (for "service") in the DNS. The SRV tape tells Minecraft the bodily host and port to use; some DynDNS services and most static DNS services allow you to set it upwards.[one]

To manually verify the SRV record, use (bold the player-facing domain is "YOUR.DOMAIN.com"):

> nslookup -q=srv _minecraft._tcp.YOUR.DOMAIN.com Server:  UnKnown Address:  [REDACTED]  Non-authoritative respond: _minecraft._tcp.YOUR.DOMAIN.com  SRV service location:           priority       = v           weight         = v           port           = 65312           svr hostname   = ACTUAL.DOMAIN.com        

FAQ (ofttimes asked questions)

Q: I take a problem which is not answered in here! What should I do to?

A: Go to the Minecraft Forums and post your problem there. To help you, they need the following data:

  • Operating system
  • Version of Java
  • I machine or multiple computers
  • Exact description of the problem
  • Steps you lot have taken to solve the problem
  • Whatever errors you encountered
  • Screenshots of the problem (if possible)
  • Annihilation else that might help us to solve your trouble - at that place almost never is too much data (passwords would be likewise much data!)

And delight, if we were able to aid you, post where the problem was exactly and what the fix was for that. Other people will appreciate that (and we will exist able to become a grip on the common problems)!


Q: On a Windows computer, when I double click the batch file it opens a command prompt window, but quickly disappears and the server does not showtime.

A: Right-click your .bat program and hit edit; add a new line and blazon pause save and run the file. If it says invalid path, information technology is probably due to an incorrect path to java.exe/javaw.exe or your Minecraft server jar file. You lot may just need to alter /jre7/ to /jre6/ . Or search your organization for coffee.exe/javaw.exe and adjust the path accordingly. (It's probably nether c:\program files or c:\program files (x86).) Also, you lot must accept the offline version of Java installed—non simply the Java plug-in for your browser.


Q: Whenever I try to go the server upward, it says "Failed to demark to port!".

A: The nigh mutual reason this happens is because you put an IP address in the server-ip field in your server.properties file. If the IP you specify isn't the same equally whatever of your network interfaces, (your wireless or wired IPv4 from ipconfig/ifconfig/ip a) Minecraft will throw the port binding failure message. By leaving it blank, you let it bind to all interfaces. You will then be able to connect using localhost and people on your wired/wireless network (in the same subnet) can connect using the computers/server's (private) IP address.

Alternatively, the mistake can mean that you take tried to use a port that is already in apply or that you do non accept permission to utilise (ports < 1024 are privileged and require root/Administrator access to bind to). You tin can try a unlike port past changing information technology in your server.properties file in this line: server-port=25565.

Note: You should avoid using the post-obit ports for your server as some ISPs may block these ports for security reasons and y'all shouldn't exist running the Minecraft server as root (in the instance of a Linux type Os and ports < 1024):

  • 21 (Used past about FTP Servers)
  • 22 (Used by Secure Trounce daemon)
  • 25 (Used past Mail Servers for SMTP)
  • 53 (Used by DNS Servers)
  • eighty (Used past well-nigh Web Servers)
  • 110 (Used by most Mail service Servers for POP3)
  • 115 (Used past Simple File Transfer Protocol)
  • 143 (Used by Mail Servers for IMAP)
  • 443 (SSL port for Web Servers)
  • 3306 (Used past almost MySQL Servers)

By and large avoid whatever port below number 1024, since those ports are generally referred too-known ports and are registered with the IANA for important services.


Q: I tried to run the server with Solaris/OpenSolaris and got the post-obit error:

coffee.io.InterruptedIOException: Performance interrupted  at java.internet.SocketInputStream.socketRead0(Native Method)  at java.internet.SocketInputStream.read(SocketInputStream.coffee:129)  at coffee.internet.SocketInputStream.read(SocketInputStream.coffee:182)  at java.io.FilterInputStream.read(FilterInputStream.java:66)  at gq.a(SourceFile:131)  at ji.chiliad(SourceFile:197)  at ji.c(SourceFile:17)  at oq.run(SourceFile:84)  2011-05-31 sixteen:57:26 [INFO] /:44673 lost connexion        

A: For whatever reason, out of all of the operating systems, only Solaris throws that exception when a thread interrupts a connection. A workaround is to alter the default beliefs on the command line:

java -Xmx1G -Xms32M -20:-UseVMInterruptibleIO -XX:+UseConcMarkSweepGC \  -XX:+CMSIncrementalPacing -XX:ParallelGCThreads=$CPU_COUNT -Twenty:+AggressiveOpts\  -jar minecraft.jar --nogui        

This instructs Java to use an interruptible IO stack instead of the default IO that is sensitive to interrupted threads.


Q: When I try to connect to my server this is what it says:

          Connection lost    The server responded with an invalid server key        

A: This mistake is unremarkably caused when the server sends an unrecognized role to the customer, which may be caused by using unrecognized server software, unbalanced client / server versions or modifications to the client.


Q: I cannot pause/place whatsoever blocks!?

A: This is most usually caused past interacting with blocks in a protected surface area. If you are trying to collaborate nearly spawn, most likely information technology has been protected, by the Minecraft server software; either build away from information technology or go operator status.


Q: My server runs fine, simply I cannot connect to it!

A: This could be caused by a serial of issues. Please post a thread using the template provided higher up.


Q: How do you give a .jar server more ram?

A: Change the numbers in the server launch command "-Xmx1G -Xms1G". The -Xms function specifies how much memory the server starts with, and the -Xmx office is the maximum corporeality of memory the server can use. -Xmx1G -Xms2G = 1GB -Xmx2G -Xms1G = 2GB And then on.


Q: Why is the server CPU constantly at full load?

A: Some users are experiences full CPU load on the server. This may be caused by the GUI (graphic user interface) window. Run the server with the --nogui option to disable this window.


Q: Help! How do y'all discover out your server's IP accost?

A: Read #Connecting to the Minecraft server


Q: I port forwarded and immune java.exe in my firewall and it'south still not working!

A: Your modem might be acting as a router too. If you switch Internet access provider's or upgrade your connection to the Cyberspace, you lot may become issued a modem/router combination (which might explain why it worked in the past). You can verify this by looking for the WAN IP of your router. If it's a private IP, y'all'll need to log into the modem/router your ISP issued to y'all, and configure port forwarding to the WAN IP of your router.


Q: I turned off my firewall on my router/modem how does information technology notwithstanding not work???!!! However, port forwarding sites written report they tin can "see" me?? What's going on???!!

A: Turning off your firewall on your router/modem ways you essentially disabled port forwarding. Port forwarding is actually a subset of firewall rules. If no rule exists on that port (for example 25565), the firewall will ignore/drib the connexion attempt (hence, you get a connexion timed out). If there is a rule, it should pass on the connexion to whatever calculator is configured to receive the initial connection attempt.

When you disable the router/modem firewall and exam your public (non RFC 1918) IP address on a port forwarding-checking website, the website will hit your router/modem, and your router/modem will respond, yes you can see me. This is another reason why disabling your firewall is bad; you incorrectly believe that people outside your network can connect to your Minecraft Server on your estimator, when really, they're trying to connect to the router/modem itself.

To solve this, the adjacent stride is to confirm if your port forwarding (rules) are correct. By Google-ing "minecraft server checker" you'll be able to check if you configured your network correctly such that users outside your network running the Minecraft client can indeed connect to your reckoner through your router/modem.

Note: Y'all may need to be careful most the Minecraft Query - It may use layer 4, the ship layer - UDP to query your server. Many Internet and Youtube guides will only tell y'all to port frontward TCP (this guide outlines that you practice both).


Q: What is connectedness timed out and connection refused?

A: Simply put, connectedness timed out is when a firewall ignores a connection attempt (ignores the intial connexion parcel with the SYN flag in the 3-way handshake). Connectedness refused is when at that place's no process listening on the port; therefore, the operating organisation lets the client (in the standard client-server model) know their connection attempt did not piece of work.

The default configuration on all Windows computers (the abode version) and (merely well-nigh) all (SOHO) routers is to driblet or time out the connections. This is called "stealth mode" and you can read more than about it on superuser. Here'southward a brief summary: "The idea is that refusing a connection instead of timing it out volition tell an attacker that there really is a computer on that IP-Address. With the connection attempt timing out, the hope is that the attacker will ignore the computer."

You can read more about connection refused on serverfault.

So if your mistake message is a connection timed out, it'southward ordinarily a firewall trouble - yous either need to let Java in the Windows firewall or port frontward. If the error message is a connection refused, perhaps your Minecraft server has not started properly or you lot turned off the firewall on your router instead of port forwarding.

Every bit always, you can always ask the Minecraft Forum if y'all are uneasy or unsure about something, particularly if opening the command prompt/terminal and running commands makes you nervous.

Connexion filtered and connectedness closed is another way of proverb timed out and refused, respectively.
