example using chkconfig

Redhat enterprise Linux comes with two nice commands

ntsysv - simple TUI (text based interface) interface for configuring runlevels.

chkconfig - chkconfig provides a simple command-line tool for maintaining the /etc/rc[0-6].d directory hierarchy by relieving system administrators of the task of directly manipulating the numerous symbolic links in those directories.

Code:
chkconfig mysqld onTurn on Apache / httpd service on boot

Code:
chkconfig httpd onTurn OFF Apache / httpd service on boot

Code:

Use --list option which lists all of the services which chkconfig knows about, and whether they are stopped or started in each runlevel:

Code:
/sbin/chkconfig --listSample O/p of above command
