This article may still be useful as a reference, but may not follow best practices or work on this or other Ubuntu releases. We strongly recommend using a recent article written for the version of Ubuntu you are using.
If you are currently operating a server running Ubuntu 12.04, we highly recommend upgrading or migrating to a supported version of Ubuntu:
Setting up a Minecraft server on Linux (Ubuntu 12.04) is a fairly easy task on the command line.
When choosing your server, be sure that it has (at a minimum)1GB of RAM, preferably at least 2GB.
The first thing you need to do is to connect to your server through SSH. If you are on a mac, you can open up Terminal, or if you are on a PC, you can connect with PuTTY. Once the command line is opened, login by typing:
ssh username@ipaddress
Enter the password when prompted. Although you can set up the server on the root user, it is not as secure as setting it up under another username. You can check out this tutorial to see how to add users.
Step One—Install the Requirements
Before going further, we should run a quick update on apt-get, the program through which we will download all of the server requirements.
sudo apt-get update
After that, we need to be sure that Java is installed on our server. You can check by typing this command:
java -version
If you don’t have Java installed, you will get a message that says “java: command not found”. You can, then, download java through apt-get:
sudo apt-get install default-jdk
You also need to supply your server with Screen which will keep your server running if you drop the connection:
sudo apt-get install screen
There is a complete guide on how to install and use screen here.
Install the Minecraft Server
Start off by creating a new directory where you will store the Minecraft files:
mkdir minecraft
Once the directory is created, switch into it:
cd minecraft
Within that directory, download the Minecraft server software:
wget -O minecraft_server.jar https://s3.amazonaws.com/Minecraft.Download/versions/1.7.4/minecraft_server.1.7.4.jar
Since we have installed screen, you can start it running (-S sets the sessions title):
screen -S "Minecraft server"
After the file downloads, you can run it with Java:
java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
The launching text should look something like this:

Your Minecraft server is now all set up. You can exit out of screen by pressing
ctl-a d
To reattach screen, type
screen -R
You can change the settings of your server by opening up the server properties file:
nano ~/minecraft/server.properties
