Setting up a MC server on Ubuntu Server 19.04

Solution 1:

Therefore, I'd like to ask what dependencies I NEED to install, and why?

You only need the JRE (preferably Java 8). This is the openjdk-8-jre-headless package on Ubuntu. You can download the server file on minecraft.net.

Then you run it like this:

$ java -Xmx1024M -Xms1024M -jar server.jar nogui

Where

• -Xmx1024M says that the server can use no more than 1024MB.
• -Xms1024M says that the server initially starts with 1024MB.
• server.jar is your Minecraft Server jar that you dowloaded
• nogui specifies that the gui is not opened. This is needed for headless since it can't open if there is no window manager.
