When starting your Linux server you may see services that are starting which may slow the boot process. i will show you how to enable\/disable certain services and which ones are essential for your system.<\/p>\n

First, a few words about runlevels. Each runlevel has a different purpose. In most Linux distributions runlevels are organized as follows:<\/p>\n

Runlevel 1 – Single-User Mode : No network interfaces, daemons, or non-root logins.
\nRunlevel 2 – Multi-User Mode: No network interfaces or daemons.
\nRunlevel 3 – Multi-User Mode with Networking: Normal start.
\nRunlevel 4 – Unused.
\nRunlevel 5 – X11: Runlevel 3 + X Window System.<\/p>\n

For more information regarding your specific distribution, please see
\nhttp:\/\/en.wikipedia.org\/wiki\/Runlevels<\/a><\/p>\n

To see what the chkconfig usage is, simply run
\nroot@host [~]# chkconfig
\nusage: chkconfig --list [name]
\n chkconfig --add name
\n chkconfig --del name
\n chkconfig [--level levels ] name on|off|reset
\n<\/code><\/p>\n

In order to determine if a service is on or off we type “chkconfig –list [name]” like so;
\n
\nroot@host [~]# chkconfig --list httpd
\nhttpd \t0:off\t1:off\t2:on\t3:on\t4:on\t5:on\t6:off
\n<\/code><\/p>\n

The following command lists all of the services are running in our system and at what runlevel they operate:
\nchkconfig --list<\/code>
\nsimilar to this

\nroot@host [~]# \/sbin\/chkconfig --list
