Preamble
This guide assumes some basic knowledge of Linux and package managers.
At minimum, a minecraft server requires Java, the minecraft server jar or an alternative server (spigot, lithium), and the ability to port forward and allow programs through your firewall.
Installing Java
As of 2023-07, Minecraft requires Java 17 to run version 1.20.1. You may need to look for a later version. Don't install the default version of Java in the repos of your chosen distro, it's very often out of date, and probably won't work with minecraft. You're going to look for any package that contains the JRE (Java Runtime Environment) or JDK (Java Development Kit). Both contain the Java Virtual Machine (JVM) and the ability to run Java programs. I like AdoptOpenJDK, but distribution of Java that fits the version requirements will work sufficient
This enables minecraft to run in the background, restart if it crashes, etc etc.
In /etc/systemd/system, place this file and tailor it to your liking.
