[cod] Running CoD servers as a Linux Daemon

[Jay Vasallo]

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

  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).
