Enable Add/Remove Software Package and yum to use installation DVD as source of software installation.

1.  To make CentOS to use DVD as source of package installation, we need to edit certain configuration file... so to make life little bit easier... just login as root user on CentOS graphical Desktop

2.  Insert the CentOS installation DVD inside the DVD drive, let the CentOS auto mount the DVD drive... or click on the the DVD drive icon that you can find when you click on computer icon on the Desktop.  Note, the figure below show example of CentOS installation DVD icon on Desktop that show the CentOS installation DVD mounted as CentOS_5.2_Final inside the /media directory...

3.  To verify CentOS DVD mount on /media/CentOS directory, just browse inside the media directory... you should see the CentOS_5.2_Final directory... see example below..

4.  Now we start the configuration process by open the x-terminal and list list all files inside the yum.repos.d directory using ll command as show on command example below.

================================

[root@pc13 ~]# ll /etc/yum.repos.d/

total 16

-rw-r--r-- 1 root root 2049 Jun 19  2008 CentOS-Base.repo

-rw-r--r-- 1 root root  659 Jul  8 20:08 CentOS-Media.repo

NOTE: you can turn back the CentOS capability to install and update software package from the internet by reversing the above command (mv /etc/yum.repos.d/CentOS-Base.repo.disable  /etc/yum.repos.d/CentOS-Base.repo)

6.  We need to edit the CentOS-Media.repo configuration file, but before we make any changes to the CentOS-Media.repo configuration file... follow command below to make backup file for the CentOS Media repo...
