The common services/daemons management arrangement in Linux is a start/stop/reset/status script in /etc/init.d/ for each service, kicked off by trigger specs in /etc/rc.d/, which in turn is managed via the chkconfig command, conventionally via corresponding chkconfig numbers coded near the top of the /etc/init.d/ script. This is to say that when the system boots at a certain run level, appropriate services are started per what is in /etc/rc.d/.
