Every operating system offers you many useful commands for managing your server. One of them is chkconfig which is used to start / stop different daemons like nfs, cups, gpm etc… which are necessary for running certain applications. Usually there are many daemons which we don’t use but still they are executed and eats up necessary dedicated server resources. You can turn them off or can disable them and can save precious server resources for other productive task to get completed. Using chkconfig you can stop few services which you think are not necessary for you hence can free server resources which are required to run them.
As you can stop such daemons you can even start them as and when required hence you never get stuck in the middle.
We can use following chkconfig commands to stop / start services :-

let’s consider nsf daemon
chkconfig –del nsf  ( –del removes nsf )
chkconfig –level 3 nsf off
now we have deleted nsf daemon form being executed and hence you have saved unnecessary server resources utilization required for executing such service.
You can use same command for disabling other services which are of no use for you.
