|
||
|
||
|
||
|
||
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.
|
||
|
||
![]()
|
||
|
||
|
||
|
||
|
||
|
||
## **Setup**
|
||
|
||
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](https://www.curseforge.com/minecraft/mc-mods?filter-game-version=2020709689%3A6756&filter-sort=4) into the minecraft server:
|
||

And we manage to login!
|
||
|
||
|
||
|
||
And that's it! We managed to log into our modded minecraft server.
|
||
|
||
## **Setup**
|
||
|
||
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

|
||
|
||

|
||

|
||
Restart=always
|
||

|
||
|
||
# Alternative: Restart the server only when it stops regularly
|
||
# Restart=on-success
|
||
|
||
# Do not remove this!
|
||
StandardInput=null

|

|
||
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
|
||
|
||
