cronjob and screen

trexostrexos Member

Hello,

I'm trying to create a restart script for my CS:S server, so I have a file called restart.sh which contains a part which kills the server (its running over screen) and a part which should start the server again. My script works great when I run it on my own, but with crontab it doesn't work. I already checked google and I read that I should use the -dmS tag for cronjob and screen, but it doesn't work either. I use this line to start the server again:
screen -dmS $SERVER ./srcds_run $PARAMS $PARAMS2

But the CS:S server doesn't start with cronjob. Can anybody help?

thanks :)

    Sure :)
    30 * * * * bash /home/css/css_server/restart.sh

    Is it possible that I should give execute rights to others? Currently the rights are: -rwxr--r--

    re you editing with crontab -e (or -u) or directly to /etc/crontab ?

  • trexostrexos Member

  • Have you tried restarting the cron service? Had issues like this before.

    I had this problem with a minecraft server as well, but I can't remember how I fixed it.

  • Often, when something works at the command line but fails in a cron job it's because of the path environment.

    Try providing the full path to screen, e.g., /usr/bin/screen

    which screen will tell you where it is.

    so I should use /usr/bin/screen -dmS $SERVER ./srcds_run $PARAMS $PARAMS2 instead of screen -dmS $SERVER ./srcds_run $PARAMS $PARAMS2?

    Yes, if you screen binary is indeed at /usr/bin/screen

    Also, ./srcds_run is a relative path which may be an issue for cron. Try substituting an absolute path like /full/path/to/srcds_run

    Well the restart.sh is located in the folder where the srcds_run is and cronjob only starts the restart.sh

    With this comman screen -dmS $SERVER ./home/css/css_server/srcds_run $PARAMS $PARAMS2 it doesn't start anymore, even when I start the restart.sh myself.

    Remove that leading dot.

    Tip: use tmux instead of screen. It's a superior, smarter (terms and keybindings that make sense), actively developed alternative.

    You should not need to restart your server everyday, if you do so then you have an issue with a plugin or aren't changing your map on a frequent enough basis.

    I had a similar cronjob to run when I used to host an Electrum node. I wrote a post on my blog when I found what was wrong (dumb syntax errors) - have look here, it might help you.
