chkconfig
chkconfig [options] [service [flag] ]
System administration command. Manipulate symbolic links in the /etc/rc.d/rc[0-6] .d directories. chkconfig manages which services will run in a specified runlevel. Valid flags are on, off, or reset to reset the service to defaults given in its initialization script in /etc/rc.d/init.d. To specify defaults in an standard initialization script, add a comment line to the script beginning with chkconfig: followed by the runlevels in which the service should run, and the start and kill priority numbers to assign—e.g., chkconfig: 2345 85 15
Options
Create a start or kill symbolic link in every runlevel for the specified service according to default behavior specified in the service's initialization script.
Remove entries for specified service from all runlevels.
Specify by number the runlevels to change. Provide numbers as a numeric string: e.g., 016 for levels 0, 1 and 6. Use this to override specified defaults.
Print whether the specified service is on or off in each level. If no service is specified, print runlevel information for all services managed by chkconfig.
