Serviceconf is a graphical application
developed by Red Hat to configure which SysV services in
/etc/rc.d/init.d are started at boot time (for
runlevels 3, 4, and 5) and which xinetd services are
enabled. It also allows you to start, stop, and restart SysV services as
well as restart xinetd.
To start Serviceconf, use one of the
following commands:
On the GNOME desktop, go to the
(on the Panel) => =>
=> .
On the KDE desktop, go to the
(on the Panel) => =>
=> .
Type the command serviceconf at a shell prompt
(for example, in an XTerm or a GNOME terminal).
Serviceconf displays the current runlevel as
well as which runlevel you are currently editing. To edit a different
runlevel, select from the pulldown menu
and select runlevel 3, 4, or 5. Refer to the section called Runlevels for
a description of runlevels.
Serviceconf lists the services from
/etc/rc.d/init.d as well as the services controlled
by xinetd. Click on a service to display a brief
description of that service at the bottom of the window.
To start, stop, or restart a service immediately, select the service and
choose the action from the pulldown menu. You
can also select the service and click the start, stop, or restart button
on the toolbar.
If you select an xinetd service such as telnet, the
Start, Stop, and
Restart buttons will not be active. If you
change the Start at Boot value of an
xinetd service, you must
click the Save Changes button to restart
xinetd and disable/enable the
xinetd services that you changed.
To enable a service at boot time for the currently selected runlevel,
check the checkbox beside the name of the service under the
Start at Boot column. After configuring the
runlevel, you must apply the changes. Select =>
from the pulldown menu or click
the Save Changes button.
 | Warning |
|---|
| | When you save changes to xinetd services,
xinetd is restarted. When you save changes to other
services, the runlevel is reconfigured, but the changes do not take
effect immediately.
|
If you check or uncheck the Start at Boot value for
a service in /etc/rc.d/init.d, the Save
Changes button will become active. Click it to reconfigure
the currently selected runlevel. The changes do not affect the system
immediately. For example, assume you are configuring runlevel 3. If you
change the Start at Boot value for the
anacron service from checked to unchecked and then
click the Save Changes button, the runlevel 3
configuration changes so that anacron is not started
at boot time. However, runlevel 3 is not reinitialized, so
anacron is still running. Select one of following
options at this point:
Stop the anacron service — Stop the
service by selecting it from the list and clicking the
Stop the selected service button. A message
will be displayed stating that the service was stopped
successfully.
Re-initialize the runlevel — Reinitialize the runlevel by
going to a shell prompt (such as an XTerm or GNOME terminal) and
typing the command telinit 3 (where 3 is the
runlevel number). This option is recommended if you change the
Start at Boot value of more than one service
and want to activate the changes immediately.
Do nothing else — You do not have to stop the
anacron service. You can wait until the system is
rebooted for the service to stop. The next time the system is
booted, the runlevel will be initialized without the
anacron service running.
