I decided to set up a minecraft server on my home server for some reason.

First install java

sudo apt update
sudo apt install default-jdk

check version

java -version

make a place for mc server

mkdir mc-server

from mc server dir, download a mc server. link can be found in mc launcher

rename the server if you wish mv server.jar mc-server.1.17.1.jar

run using java -Xmx1024M -Xms1024M -jar mc-server.1.17.1.jar nogui

to accept eula, change set eula=true in eula.txt

allow through firewall if needed sudo ufw allow 25565

run -jar mc-server.1.17.1.jar --help to get help

run using java -Xmx1024M -Xmx4G -jar mc-server.1.17.1.jar nogui to get bigger memory size

server.properties file allows configuration

see https://minecraft.fandom.com/wiki/Server.properties for how to configure.

reverse proxy to server using frp

[Minecraft]

type = tcp
local_ip = 127.0.0.1
local_port = 25565
remote_port = 25565

Fix this error

java.lang.UnsupportedClassVersionError: net/minecraft/server/Main has been compiled by a more recent version of the Java Runtime (class file version 60.0), this version of the Java Runtime only recognizes class file versions up to 55.0

add repo sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt install openjdk-17-jdk

Installing datapack

There are great datapacks here https://vanillatweaks.net/picker/datapacks/

Put files in the datapack folder

Type /reload to reload after install when server’s running

Run /datapack list enabled to check what’s loaded
