What other people have suggested is good, but personally i'd do it more
simply. For simple custom stuff like this, i can't be bothered with all
that runlevel / rcx.d stuff - there's no need.

I'd just add a line at the bottom of /etc/rc.d/rc.local to start it on
boot. (rc.local is run after the system startup scripts at boot time.) If
you're not concerned about it stopping tidily - i.e., you don't mind it
just being killed unceremoniously on shutdown - this is usually the
simplest way.

If you want it to do anything special on shutdown, then you'll probably
be better off doing as others have suggested.
