4.13.3.2. Enabling Supplementary and Optional Repositories

As systems are subscribed to products, the associated content repositories (identified in the entitlement certificate) are made available to the system. The content repositories are based on the product and on the content delivery network, defined in the baseurl parameter of the rhsm.conf file.

A subscription may include access to optional content channels along with the default channels. These optional channels must be enabled before the packages in them can be installed (even if the system is fully entitled to the products in those channels).

1. List all available repos for the system, including disabled repos.

   [root@server ~]# yum repolist all
   repo id                      repo name                           status
   rhel-6-server                Red Hat Enterprise Linux 6Server -  enabled
   rhel-6-server-beta           Red Hat Enterprise Linux 6Server Be enabled
   rhel-6-server-optional-rpms  Red Hat Enterprise Linux 6Server Op disabled
   rhel-6-server-supplementary  Red Hat Enterprise Linux 6Server Su disabled

   The optional and supplementary channels are named rhel-6-server-optional-rpms and rhel-6-server-supplementary, respectively.
2. The repositories can be enabled using the yum-config-manager command:

   [root@server ~]# yum-config-manager --enable rhel-6-server-optional-rpms

Alternatively, simply specify the optional or supplementary repository when installing a package with yum. This uses the --enablerepo repo_name option. For example:

# yum install rubygems --enablerepo=rhel-6-server-optional-rpms
Loaded plugins: product-id, refresh-packagekit, subscription-manager
Updating Red Hat repositories.
....

Using yum is described in Chapter 5, Yum.

4.13.3.3. Disabling the Subscription Manager Repository

When a system is registered using Subscription Manager, the rhsmcertd process creates a special yum repository — redhat.repo. As Section 4.13.3.2, “Enabling Supplementary and Optional Repositories” describes, as the system adds subscriptions, the product channels are added to the redhat.repo file.

Maintaining a redhat.repo file may not be desirable in some environments. It can create static in content management operations if that repository is not the one actually used for subscriptions, such as for a disconnected system or a system using a local content mirror.

This default redhat.repo repository can be disabled by editing the Subscription Manager configuration and setting the manage_repos value to zero (0).

[root@server1 ~]# subscription-manager config --rhsm.manage_repos=0
