1. Mount the RHEL 6 installation ISO somewhere like /mnt, e.g.:
# mount -o loop rhel6.iso /mnt
2. Copy the media.repo file from the root of the mounted ISO to /etc/yum.repos.d/ and set the permissions. e.g.:
# cp /mnt/media.repo /etc/yum.repos.d/rhel6dvd.repo # chmod 644 /etc/yum.repos.d/rhel6dvd.repo
3. Edit the new repo file, change the gpgcheck=0 setting to 1 and add the following 3 lines (make sure to replace “Server” with “Client” or “Workstation“, depending on the type of RHEL DVD in use):
enabled=1 baseurl=file:///mnt/rhel6dvd/Server gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
4. In the end, the new repo file could look like the following (though the media-id will be different depending on the version of RHEL):
[dvd-Server] name=DVD for Red Hat Enterprise Linux 6.6 Server mediaid=1359576196.686790 metadata_expire=-1 gpgcheck=1 cost=500 enabled=1 baseurl=file:///mnt/rhel6dvd/Server gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
5. As a final step, it might be a good idea to run the command yum clean all once.
# yum clean all
Add optional repositories
To configure access to the supplementary packages in the directories HighAvailability, LoadBalancer, ResilientStorage, and ScalableFileSystem, add additional repositories for them in the same file, e.g.:
[dvd-HighAvailability] mediaid=1359576196.686790 name=DVD for RHEL6 - HighAvailability baseurl=file:///mnt/rhel6dvd/HighAvailability gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release enabled=1 gpgcheck=1
[dvd-LoadBalancer] mediaid=1359576196.686790 name=DVD for RHEL6 - LoadBalancer baseurl=file:///mnt/rhel6dvd/LoadBalancer gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release enabled=1 gpgcheck=1
[dvd-ResilientStorage] mediaid=1359576196.686790 name=DVD for RHEL6 - ResilientStorage baseurl=file:///mnt/rhel6dvd/ResilientStorage gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release enabled=1 gpgcheck=1
[dvd-ScalableFileSystem] mediaid=1359576196.686790 name=DVD for RHEL6 - ScalableFileSystem baseurl=file:///mnt/rhel6dvd/ScalableFileSystem gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release enabled=1 gpgcheck=1
