How to set up a Minecraft server on Linux

A Minecraft server on Linux (in this case: Ubuntu 20.04) is quick and easy to set up. Once you have the right hardware ready for hosting, all you need is a current Java version and the latest program files of the sandbox computer game. You can obtain both conveniently via the terminal in Linux.

Hosting options where you can choose between Windows and Linux as the server operating system are available from a wide range of providers — including IONOS. Here, the vServer or VPS (Virtual Private Server) server model is recommended for an easy start with a smaller Minecraft Linux server for a few people. For a low monthly fixed price, you get access to virtualised hardware resources that you can scale up and down at any time. As a generally suitable package with the required computing power, we recommend VPS M.

In the table below you can find three concrete example use cases for a Minecraft server with Linux including matching server options from IONOS.

If you want to run your Minecraft server on a Linux distribution, the choice is yours. The usual suspects such as Debian, Ubuntu, or OpenSUSE are possible as a system base as well as Arch Linux, Solus, Gentoo Linux or other, less common Linux distributions. In the following tutorial, we show the individual steps for setting up a Minecraft server using Ubuntu 20.04 as an example.

Connect to your Linux server by setting up a remote desktop connection or by making an SSH connection with PuTTy.

Once the connection is established, your first step is to install the additional components required to run a Minecraft server via the terminal.

To do this, first update the package index of the package manager APT:

In the next step, you install the minimal OpenJDK Java runtime environment (headless), which is mandatory for running the Minecraft server application programmed in Java:

To keep the Minecraft server active when you leave the terminal, also install the full-screen window manager Screen:

After you have installed the basic components for your Minecraft server on Linux, the next step is to enable TCP port 25565. By default, the server application uses this port to communicate with clients, so a corresponding firewall rule is essential. Use the following command to add the new policy:

Now find the installation files behind the copied link using wget:

After you have downloaded the server.jar file, you can run the server application at any time. Use the window manager screen installed in the first step, which you start with the following command:

Confirm the start of the manager with the space bar. Afterwards you will see the familiar terminal interface, which is now ready for the start of the Minecraft server. To do this, execute the following input:

So, on the one hand, the eula.txt file could not be loaded, and on the other hand, the Minecraft server is missing configuration information that is to be defined by default in the server.properties file.

The End User License Agreement (EULA) consent file is subsequently generated directly in the current directory. You can open the file as follows:

Once you have agreed to the license agreement, you can turn to the server.properties configuration file. This was also created in the current directory when the server application was started for the first time. Open the file with the text editor nano:

After you have agreed to the EULA conditions and saved your individual server configuration, you can now type the command already used in Step 4 for starting the Minecraft server in the Linux terminal one more time:

After successful startup process — which takes some time — the terminal displays the message:

Once you have the Minecraft server up and running on Linux, you will of course want it to remain active when you disconnect remotely from the server. To initiate this, first exit the screen session with the key combination [Ctrl] + [A] + [D].

Then run the following command to display all active screen sessions:

Now, to keep this session active even if you log off the server later, enter the following into the terminal — replacing the value `2385´ with the individual ID of your screen session:

Now you can close the screen window at any time with the key combination [Ctrl] + [A] + [D] and log out of your server without closing the Minecraft server.
