Simple Instructions: 1.3 Setup (MC 1.17.1 or newer, Linux, Start Script)

In this example, we suppose, that you installed the Minecraft server in the directory "/opt/minecraft/servers/Minecraft Server/" and use the Minecraft version 1.18.1 and the Forge version 39.0.17.

First, you create a file named start.sh in the "/opt/minecraft/servers/Minecraft Server/" directory.
Next, you insert the start script into the start.sh file:

bash -c 'cd <Path of your Minecraft server>; screen -d -m -S <Name of your Screen, i.e. your directorys name without spaces> java -Xmx<Amount of RAM in gigatytes you want to allocate to Minecraft>G @libraries/net/minecraftforge/forge/<Minecraft version>-<Forge version>/unix_args.txt

In our example we give the Minecraft server 6 GB RAM to use, with the directory "/opt/minecraft/servers/Minecraft Server/", Minecraft version 1.18.1 and Forge version 39.0.17 it would look like this:

bash -c 'cd /opt/minecraft/servers/Minecraft Server/; screen -d -m -S MinecraftServer java -Xmx6G @libraries/net/minecraftforge/forge/1.18.1-39.0.17/unix_args.txt

Last, we have to feed the configuration file named auto_restart-server.toml. It is located in the world/serverconfig directory in the installation directory of your server. In our example, is in the directory "/opt/minecraft/servers/Minecraft Server/world/serverconfig".
In the config file, we have to set use_external_restart_script to false and restart_command to "<Path of your Minecraft server>/start.sh".

#Options for restarting:
[restart]
	#Is the server started by an external restart script?
	use_external_restart_script = false
	#Command that is executed on Server stopped to restart the server. Only called if "[restart, use_external_restart_script]" is false.
	restart_command =  "<Path of your Minecraft server>/start.sh"

In our example, it would look like this:

#Options for restarting:
[restart]
	#Is the server started by an external restart script?
	use_external_restart_script = false
	#Command that is executed on Server stopped to restart the server. Only called if "[restart, use_external_restart_script]" is false.
	restart_command =  "/opt/minecraft/servers/Minecraft Server/start.sh"

Now we can start the Minecraft server and the Minecraft server restarts, if you use the /restart command.

After testing that the Minecraft server can restart, we continue configuring the features of the Auto Restart mod, starting with the mod naming Auto Restart feature.
