Configuration for GNU Linux Fedora Computer using Linux Command

 

    Using the chkconfig command to enable Linux service at boot up and make service start automatically when you boot up or change runlevel on Linux Fedora machine.  The step by step example below show how to enable service on Linux Fedora machine.... more specifically ... we enable web server (httpd) to automatically start each time the Linux machine reboot.

Command use on this example:

# chkconfig --list

# chkconfig --list httpd

# chkconfig --level 35 httpd on

# chkconfig --help

 

The example below show how to enable web server on Linux Fedora machine...

1.  List all service available on you r Linux machine using chkconfig command.....

List all services on Liux machine using chkconfig command

[root@fedora ~]# chkconfig --list

httpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off

[root@fedora ~]#

 

To start web server automatically on fedora Linux...

   The Fedora machine usually start on either runlevel 3 or runlevel 5... the chkconfig command example below show, how to enable automatically start the Fedora web server (httpd) on runlevel 3 and runlevel 5..

On httpd services

[root@fedora ~]# chkconfig --level 35 httpd on

[root@fedora ~]#

 

To verify the changes by using the chkconfig command as example below... make sure that the runlevel 3 and 5 mark as on...

Verify httpd automatically start on boot up

[root@fedora ~]# chkconfig --list httpd

httpd 0:off 1:off 2:off 3:on 4:off 5:on 6:off
