The chkconfig command can also be used to activate and
deactivate services. The chkconfig --list
command displays a list of system services and whether they are started
(on) or stopped (off) in runlevels
0-6. At the end of the list is a section for the services managed
by xinetd.
If the chkconfig --list command is used to query a service
managed by xinetd, it displays whether the
xinetd service is enabled (on) or
disabled (off). For example, the command
chkconfig --list finger returns the following output:
As shown, finger is enabled as an
xinetd service. If xinetd is
running, finger is enabled.
If you use chkconfig --list to query a service in
/etc/rc.d, service's settings for each
runlevel are displayed. For example, the command chkconfig --list
httpd returns the following output:
httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off |
chkconfig can also be used to configure a service to
be started (or not) in a specific runlevel. For example, to turn
nscd off in runlevels 3, 4, and 5, use the following
command:
chkconfig --level 345 nscd off |
 | Warning |
|---|
| | Services managed by xinetd are immediately affected
by chkconfig. For example, if
xinetd is running, finger is
disabled, and the command chkconfig finger on is
executed, finger is immediately enabled without
having to restart xinetd manually. Changes for
other services do not take effect immediately after using
chkconfig. You must stop or start the individual
service with the command service
daemon stop. In the previous
example, replace daemon with the name of
the service you want to stop; for example, httpd.
Replace stop with start or
restart to start or restart the service.
