# Copy this file to /etc/systemd/system/
#
# Create a new directory in /opt/minecraft to hold each game. In this example:
# /opt/minecraft/serverdirectory1
# /opt/minecraft/serverdirectory2
# ...
#
# Rename the Minecraft .jar to current-minecraft.jar
#
# Start a game in each directory to create all necessary files, and accept the EULA
#
# In each directory, modify server.properties:
# server-ip=<your server's IP>
# server-port=<your game's port, unique for each game>
# enable-rcon=true
# rcon.port=<a unique port for each game, NOT same as server-port>
# rcon.password=<an admin password you choose, same for each game>
#
# Install mcrcon:
# $ cd /opt/minecraft
# $ git clone https://github.com/Tiiffi/mcrcon
# $ cd mcrcon
# $ gcc -std=gnu11 -pedantic -Wall -Wextra -O2 -s -o mcrcon mcrcon.c
# $ sudo cp mcrcon /bin/bash/mcrcon
#
# Create /etc/mcrcon.conf
# RCON_PASSWD=(password you set in server.properties)
# SERVER_IP=(IP address of this server)
# <serverdirectory1>=<rcon.port from serverdirectory1/server.properties>
# <serverdirectory2>=<rcon.port from serverdirectory2/server.properties>
# ...
# Note that <serverdirectory> is case-sensitive, and relative to /opt/minecraft.
#
# Enable the service:
# $ sudo systemctl enable minecraft@serverdirectory1
# $ sudo systemctl enable minecraft@serverdirectory2
#
# Configure your client to connect to each game server:
# Server Name = Something that refers to your game
# Server Address = <your server's IP>:<your game's port>
