Resolution

Automatic configuration


Red Hat Customer Portal Labs provides a [Yum Repository Configuration Helper](https://access.redhat.com/labs/yumrepoconfighelper/) for automatically setting up a yum repository, based on your environment and deployment goals. The [Yum Repository Configuration Helper](https://access.redhat.com/labs/yumrepoconfighelper/) incorporates the information included in this document but makes it easier to generate valid and support-recommended configurations.

Manual configuration

Note Refer to "How do I set up an up2date or yum repository from a locally-mounted DVD on Red Hat Enterprise Linux?" for other OS versions.

  1. Mount the Red Hat Enterprise Linux 5 installation ISO somewhere like /media/rhel5dvd, e.g.:

    # mount -o loop RHEL5.9-Server-20121129.0-x86_64-DVD.iso /media/rhel5dvd

    If you use DVD media, you can mount like below. 

    # mkdir -p  /mnt/disc
# mount /dev/sr0  /mnt/disc

  2. Check the numeric value found on the first line of the .discinfo file from the mounted DVD

    # head -n1 /media/rhel5dvd/.discinfo
1354216429.587870

  3. Create a new file in /etc/yum.repos.d/, e.g. /etc/yum.repos.d/dvd.repo and add the following content to it

    [dvd-Server]
mediaid=1354216429.587870
name=RHEL 5 Server DVD
baseurl=file:///media/rhel5dvd/Server
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
enabled=1
gpgcheck=1

    Customize the file appropriately, i.e.:

    • The value of baseurl must match up with where the DVD was mounted in step #1
    • If using Red Hat Enterprise Linux Client or Workstation, the last directory in the baseurl will need to be changed to Client
    • Set the numeric value found from .discinfo file to mediaid.

  4. As a final step, it might be a good idea to run the command yum clean all once
    Also note that if the system is not registered to Red Hat Network, yum can be run with the --noplugins option to prevent it from connecting to RHN

How to add optional repository

To configure access to the supplementary packages in the directories Cluster, ClusterStorage, VT, add additional repositories for them in the same file, e.g.:

[dvd-cluster]
mediaid=1354216429.587870
name=DVD for RHEL5 - Cluster
baseurl=file:///media/rhel5dvd/Cluster
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
enabled=1
gpgcheck=1

[dvd-cluster-storage]
mediaid=1354216429.587870
name=DVD for RHEL5 - ClusterStorage
baseurl=file:///media/rhel5dvd/ClusterStorage
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
enabled=1
gpgcheck=1

[dvd-vt]
mediaid=1354216429.587870
name=DVD for RHEL5 - VT
baseurl=file:///media/rhel5dvd/VT
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
enabled=1
gpgcheck=1

# Note: Make sure to customize the above as in step #3.

Optional and specific to Red Hat Enterprise Linux 5 Client: To configure access to the packages in the Workstation directory, add a repo stanza to the above file for that as well, e.g.:

[dvd-workstation]
mediaid=1354233478.680018
name=DVD for RHEL5 - Workstation
baseurl=file:///media/rhel5dvd/Workstation
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
enabled=1
gpgcheck=1
