RHEL/Centos init script for a Catalyst FCGI server

Under the line
ReplyDelete> SCRIPT_ARGS="-l $RUN_DIR/socket -p $RUN_DIR/pid -d"
might as well use the socket and run variables. So it would look something like
> SCRIPT_ARGS="-l $SOCKET_FILE -p $PID_FILE -d"
Yes... it was a mispaste ;) Thank you Jason!
ReplyDeletePass daemon the --pidfile option so that __pids_var_run() can find the application's pid file. This will keep you from starting multiple copies of your application. Putting your pid in the default location (/var/run/BASENAME OF APP.pid) so that it will be found by default would probably be cleaner.
ReplyDeleteAlso, look into the --proc_title option to your Catalyst application. If you run multiple instances of your application (as we do) it's a lot easier to manage the application when the main process has a unique name.
this is an old version of the script... I should update it ;)
