Light python script to create a Java Edition Minecraft Server

I have been using How to Make Minecraft Server on Ubuntu 20.04 to make a solid Minecraft server. This also works for Ubuntu 22.04. I am essentially breaking up this instructions into a python script to automate the process. I will then test it out in an Ubuntu 22.04 VM to ensure it works properly.

I initially crated bash scripts to automate the process. minecraft-install.sh is the script that can also be run to automate the process as well.

Minecraft Jar files:

• 1.20.5
• 1.20.6

Dependencies

To be Installed during installation

• git
• build-essentials
• openjdk-21(or latest version)
• mcrcon repository: https://github.com/Tiiffi/mcrcon.git
• Optional: UFW Firewall to set firewall rules

Required prior to running the script

• Ensure sed is installed
• Inquirer and subprocess for the python script

Running the Python Script

1. Run the script with
   • sudo python3 mc-installer.py
2. Enter the password for mcrcon when prompted
3. Paste in the link to the Minecraft Jar file.
4. When installation is complete, run the following to verify that everything worked:
   • sudo systemctl status minecraft

Un-install Minecraft

1. Run the script with
   • sudo python3 mc-installer.py
   • Select Uninstall
   • Enter the name of the minecraft server. If the default was left during installation, leave the default name during this process.

Running the Shell Code

1. Set minecraft-install.sh to an executable. It will set all necessary files as executable: chmod +x File-Name
2. Run ./minecraft-install.sh
3. The minecraft-install.sh will perform the following:
   • Edit the eula.txt file: eula=true
   • Update the server.properties
     • rcon.port=25575
     • Prompt you to set the rcon.password
     • enable-rcon=true
   • Add the minecraft.service file to the directory: /etc/systemd/system
   • Reload the daemon: daemon-reload
   • Start the service: sudo systemctl start minecraft
   • Enable service to start after rebooting: sudo systemctl enable minecraft
   • Create script to backup the server file
4. Accessing the console
   • /opt/minecraft/tools/mcrcon/mcrcon -H 127.0.0.1 -P 25575 -p strong-password -t
