On this document I will go through a series of steps to add a local DVD to a RPM based Linux server and then use it as a Yum repository to install software.

Step 1 - Insert the Linux DVD containing the required software and then issue the command scsi-rescan

NOTE: For help on how to add a Linux DVD to a Virtual Box VM check this other blog.

Step 2 -Create the /media/dvd directory if not already present.

Step 3 - Mount the DVD to the /media/dvd directory
# mount /dev/cdrom /media/dvd

Step 4 - Add and edit the /etc/yum.repos.d/rhel-dvd.repo file to make it have this content:
[dvd]
name=Red Hat Enterprise Linux Installation DVD
baseurl=file:///media/dvd

Step 5 - Edit the /etc/yum.conf file to set the gpgckeck parameter to 0(zero) to disable checking signatures of packages.

Your system should be ready to install software from the DVD.

Step 6 - Use yum as follows to use your DVD repository:
# yum install/search --enablerepo=dvd –nogpgcheck [software]
