Network Services -- Configure the service to start when the system is booted

Services can generally be started in 2 ways - on demand, and at bootup. The on demand startup is easy, service nfs start or /etc/init.d/nfs start.
Starting services at bootup is often controlled through the command chkconfig.
Below are several primary commands for using chkconfig, the NFS daemon will be used for the examples
  • List services and startup configuration
    • chkconfig --list
  • Configure service to start on boot
    • chkconfig nfs on
  • Configure service to start at a specific runlevel
    • chkconfig --level 3 nfs on
  • Configure service not to start on boot
    • chkconfig nfs off
  • Add a service to the list of services
    • chkconfig --add nfs
  • Remove a service from the list of services
    • chkconfig --del nfs
