Hello

I want to run minecraft server as linux service, i'm using this code

# /etc/init.d/minecraft

#Settings
SERVICE='minecraft_server.jar'
USERNAME="user"
MCPATH='/home/user/Escritorio/Minecraft'

mc_start() {
if ps ax | grep -v grep | grep $SERVICE > /dev/null
        then
                echo "Tried to start but $SERVICE was allready running!"
        else
                echo "$SERVICE was not running... starting."
        cd $MCPATH
        su - $USERNAME -c "cd $MCPATH && screen -dmS minecraft java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui"
                sleep 7
        if ps ax | grep -v grep | grep $SERVICE > /dev/null
        then
                echo "$SERVICE is now running."
        else
                echo "Could not start $SERVICE."
        fi
        fi
}

mc_stop() {
    if ps ax | grep -v grep | grep $SERVICE > /dev/null
        then
                echo "$SERVICE is running... stopping."
                su - $USERNAME -c "screen -p 0 -S minecraft -X stuff "stop""
                su - $USERNAME -c "screen -p 0 -S minecraft -X stuff `echo '\015'`"
                sleep 7
        else
                echo "$SERVICE was not running."
        fi
        if ps ax | grep -v grep | grep $SERVICE > /dev/null
        then
        echo "$SERVICE could not be shut down... still running."
        else
    echo "$SERVICE is shut down."
    fi
}

mc_update() {
if ps ax | grep -v grep | grep $SERVICE > /dev/null
        then echo "$SERVICE is running! Will not start update."
else
    su - $USERNAME -c "cd $MCPATH && cp -r world world_`date "+%d.%m.%Y"`"
        su - $USERNAME -c "cd $MCPATH && mv minecraft_server.jar "minecraft_server_`date "+%d.%m.%Y"`.jar""
        su - $USERNAME -c "cd $MCPATH && wget http://www.minecraft.net/download/minecraft_server.jar?v=1289500485639"
        su - $USERNAME -c "cd $MCPATH && mv minecraft_server.jar?v=1289500485639 minecraft_server.jar"
fi

}
#Start-Stop here
case "$1" in
  start)
    mc_start
    ;;
  stop)
    mc_stop
    ;;

  restart)
    mc_stop

This script works correctly but i want to send commands and i don't know how i could do it

Hi yunxao,

I am using this code as well. I hope you have changed the USERNAME and MCPATH in that script to your own.
To send commands you just have to type in ssh either:-

/etc/init.d/minecraft start

/etc/init.d/minecraft stop

/etc/init.d/minecraft restart

/etc/init.d/minecraft update

Depending on what you want to do. Hope that answers your question.

I am running Debian Lenny. When I run

/etc/init.d/minecraft start

the server starts and i have confirmed that the process is running but it doesn't get listed on http://www.minecraft.net/servers.jsp.

Also get the following error when trying to stop/restart the server:-

minecraft_server.jar is running... stopping.
There are several suitable screens on:
15957.minecraft(05/12/10 13:22:39)(Detached)
14998.minecraft(05/12/10 12:31:58)(Attached)
15412.minecraft(26/11/10 13:54:29)(Dead ???)
15586.minecraft(26/11/10 13:54:29)(Dead ???)
Remove dead screens with 'screen -wipe'.
Use -S to specify a session.

minecraft_server.jar could not be shut down... still running.

So I have to shutdown using

kill -9 [PID]

which isn't a big deal really.

/etc/init.d/minecraft update

works fine.

Server runs fine and gets listed when I run it this way:-

java -cp minecraft-server.jar com.mojang.minecraft.server.MinecraftServer

But I need it running properly as a service.
Any ideas? Thanks
