The problem is: nobody tells anybody to run that script at startup. I suggest you read the manpages of regarding "runlevels" and "init" to get a better understanding about how the startup process of a *ix-system works (notice that there are 2 fundamental layouts, "SysV" and "BSD").

To solve your problem: put (a link to) the script into "/etc/rcN.d", and name it Snn where "nn" is a two-digit number and "N" is the number of the runlevel whichs start you want to trigger the script. Or you can write a configuration file for init and place it in "/etc/init.d". Read the man page for init(5) to find out which format this has to be.

With Fedora/CentOS/RedHat you can also use the "chkconfig" utility to automatically place start/stop-scripts for arbitrary services into the various rc-directories. In this case you would have to change your script to accept "start", "stop" and "status" as parameters and create a pseudo-service from it.

I hope this helps.
