Now the minecraft server is up, let's check if it works, first install minecraft on your client::
[ 10.66.66.2/32 ] [ /dev/pts/135 ] [~]
→ yay -S minecraft-launcher
[ 10.66.66.2/32 ] [ /dev/pts/135 ] [~]
→ which minecraft-launcher
/usr/bin/minecraft-launcher
Next if you need to port forward the mc server to the public, it will be on port 25565.
Now if you want to make a modded server, you will need a few things, first you will need minecraft forge install:
[ 10.66.66.2/32 ] [ /dev/pts/138 ] [~]
→ cd Downloads
[ 10.66.66.2/32 ] [ /dev/pts/138 ] [~/Downloads]
→ java -jar forge-1.12.2-14.23.5.2855-installer.jar
This will open the forge installer, select client this time:
And then we can login once again into the server:
Now let's add a mod into the minecraft server:

And we manage to login!
And that's it! We managed to log into our modded minecraft server.
For the players who want to download the mods they need to log into the server, you can setup a simple nginx to allow them to get there:
root@minecraft:~# vim /etc/nginx/sites-available/default
root@minecraft:~# cat /etc/nginx/sites-available/default
server {
listen 80 default_server;
listen [::]:80 default_server;
root /home/mcuser/minecraft/mods;
index index.html index.htm index.nginx-debian.html;
server_name _;
autoindex on;
location / {
try_files $uri $uri/ =404;
}
}
root@minecraft:~# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
root@minecraft:~# nginx -s reload
Now let's make a systemd service to launch our minecraft server
root@minecraft:~# vim /etc/systemd/system/minecraft.service
root@minecraft:~# cat /etc/systemd/system/minecraft.service

Nov 18 08:16:11 minecraft systemd[1]: Started Minecraft Server.
For other minecraft versions you will need to install other java versions, sadly you need to deal with oracle being a corporation and you may need to login there. You're going to need either openjdk 11 or 17+, openjdk 11 being the cutover version from minecraft 1.16.5
use java version 1.8.0 (download it from the oracle website) to make a minecraft server 1.12.2 or on 1.16.5
>> https://www.oracle.com/java/technologies/downloads/archive/ (yes you need to create an account there, just fill it with garbage data)
Until there is Nothing left.
