[cod] Running CoD servers as a Linux Daemon

[Jay Vasallo]

No screen needed. Don't know why anyone would want to run the process if they didn't need to. Does it have any denefits or help the game in any way?

  Thanks Jay.  I was wondering about the use of Screen within a Daemon job. 

  Any suggestions as to the run startup script for CoD is you don't use screen and use setusergid?

    I do not use screen with daemon tools. The run file that you create, or your start script is monitored thru daemon. If the process is killed with a console command 

    \rcon quit, 

    the supervise process restarts the server. 

    If you have mutliple servers booting off of  main game installtion files, it is always wise to leave a server config in the main installtion. When the server starts it will use the main installtion server.cfg if the user's config is not present.

    If a client does not have a file or config properly edited or in the correct folder, the process will not restart. Always keep a server.cfg located in your main installation. 

    Example:

    Main installation server config at /games/cod/cod-server/uo/server.cfg

    User's server config at /home/user/cod-server/uo/server.cfg

    If configs are not present, I have seen the process take the whole cpu at 99%. 


    Daemontools is good program if installed correctly. Once installed, the program will create a folder called /service 
    cd /service

    Now create a folder and name it whatever the user is named.

    mkdir sbclan

    Now if you do the "ls" command, you will notice that there is now a folder called /service/sbclan/supervise 
    This is made by daemon tolls. Don't even bother with this folder. Let it be.

    Now you have to have created a start script and call it run. Copy the run file so it ends up as 
    /service/sbclan/run. The run file has have the setusergid command within the file . http://cr.yp.to/daemontools/setuidgid.html

    now "chmod +x run" and the service will start. you will also notice that the server has started.

    svc -d /service/sbclan  - will kill the server.
    svc -u /service/sbclan - will restart the server


    Once in a great while, I enter my ventrilo boxes and give the "ps aux" command to see all the processes. If a notice an error, i killed the process by thru daemon and search for the config error. After correcting the error, I would restart the process.

    I like using it, unlike many other people.

    cheers

      > You can run them on deamon tools

      Does deamontools let you monitor a screen process?  I've tried Cron and ended up with multiple server instances (periodically, like one extra server per day or so).
