Red Hat Start Scripts and Order of Operations

From Notes

Red Hat uses chkconfig or ntsysv to control which programs start for each runlevel. ntsysv is very easy to use and controls all scripts for the current runlevel through a graphical display -- try it. chkconfig is a command line tool that gives you incredible control over the details of your script scripts.

List all scripts in chkconfig

chkconfig --list

List all scripts that start for each runlevel

chkconfig --list | grep on

Add or remove a script from a specific runlevel

chkconfig --level X[X..] <script> on[|off]

Example: add cvsd to levels 3, 4, and 5 as on, rest as off:

chkconfig --add cvsd            # Adds cvsd to all levels as 'off'
chkconfig --level 345 cvsd on   # Modifies entry to levels 345 to 'on'
