How To Set Up a Minecraft Server on Linux

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
