Using chkconfig to Enable Services

Many system services are disabled by default, but can be reactivated through the use of chkconfig. Use the following command to list the services that are disabled for all runlevels:

chkconfig --list | grep -v :on
      

You may notice that there are some services that you wish to use; in which case chkconfig can be used to enable them. For example, if you'd like to enable named, simply issue the following command:

chkconfig named on
      

See the chkconfig man page for more information.
