How to use the Restart Mod

You can let the mod use the restart command to restart the server, or use an external restart script.
The script examples are Linux sh scripts.
You can find Windows script examples on: https://github.com/GeheimagentNr1/AutoRestart/wiki/Windows-Scripts

Restart Command

These scripts are for the use, if you have configured, that you are using an external restart script.
The first script is named "restart_start.sh". It is used to start the "restart_loop.sh" script in a screen.
bash -c 'cd <Path of your Minecraft server>; screen -d -m -S <Name of your Screen, i.e. your folders name without spaces> java -jar forge-<Minecraft version>-<Forge version>.jar'

External Restart Script

These scripts are for the use, if you have configured, that you are using an external restart script.
The first script is named "restart_start.sh". It is used to start the "restart_loop.sh" script in a screen.
bash -c 'cd <Path of your Minecraft server>; screen -d -m -S <Name of your Screen, i.e. your folders name without spaces> ./restart_loop.sh'

The "restart_loop.sh" script has the logic in it, to restart or stop the server. It will restart the server always, except in the "./auto_restart/restart" file is "0".
The Auto Restart Mod writes "-1", "0" or "1" to the file.
When the script reads the file,
– "-1" means that server crashed.
– "0" means the server was shutdown with the "/stop" command and should be stopped.
– "1" means the server that the server was stopped with the "/restart" command or an auto restart and should be restarted.

After the server was stopped for a restart, the script waits 5 seconds until it restarts the Minecraft server.
while true
do
    java -Xmx<Amount of RAM in gigatytes you want to allocate to Minecraft>G -jar forge-<Minecraft version>-<Forge version>.jar
    read -r should_restart < ./auto_restart/restart
    if [ $should_restart == "0" ]
    then
        break
    fi
    echo 'If you want to stop the server completely, press STRG-C, \before the countdown is at 1!'
    echo "Rebooting in:"
    for i in 5 4 3 2 1
    do
        echo "$i…"
        sleep 1
    done
    echo 'Server restarts!'
done
