Yum: add a local cdrom repository

This is useful when you want to install packages from the local cdrom or .iso file

Tested on rhel 6.2

Mount the cdrom

This can be a locally attached cdrom or an iso file:

# Mount locally attached cdrom
mount /dev/cdrom /mnt/cdrom

# Mount iso file
mount -o loop filename-server-6.2.iso /mnt/cdrom

Create the .repo file

Create a file: /etc/yum.repos.d/cdrom.repo

[cdrom]
name=cdrom
baseurl=file:///mnt/cdrom
enabled=1
gpgcheck=0

Yum away!

Now you can run yum install against the packages on the DVD/CD
