8.4.5. Adding, Enabling, and Disabling a Yum Repository
8.4.5. Adding, Enabling, and Disabling a Yum Repository Section 8.4.2, "Setting [repository] Options" described various options you can use to define a Yum repository. This section explains how to add, enable, and disable a repository by using the yum-config-manager command. Important When the system is registered with the certificate-based Red Hat Network , the Red Hat Subscription Manager tools are used to manage repositories in the /etc/yum.repos.d/redhat.repo file. See Chapter 6, Registering the System and Managing Subscriptions for more information how to register a system with Red Hat Network and use the Red Hat Subscription Manager tools to manage subscriptions. Adding a Yum Repository To define a new repository, you can either add a [ repository ] section to the /etc/yum.conf file, or to a .repo file in the /etc/yum.repos.d/ directory. All files with the .repo file extension in this directory are read by yum , and it is recommended to define your repositories here instead of in /etc/yum.conf . Warning Obtaining and installing software packages from unverified or untrusted software sources other than Red Hat Network constitutes a potential security risk, and could lead to security, stability, compatibility, and maintainability issues. Yum repositories commonly provide their own .repo file. To add such a repository to your system and enable it, run the following command as root : yum-config-manager --add-repo repository_url where repository_url is a link to the .repo file. For example, to add a repository located at http://www.example.com/example.repo, type the following at a shell prompt: Enabling a Yum Repository To enable a particular repository or repositories, type the following at a shell prompt as root : yum-config-manager --enable repository where repository is the unique repository ID (use yum repolist all to list available repository IDs). Alternatively, you can use a glob expression to enable all matching repositories: yum-config-manager --enable glob_expression For example, to enable repositories defined in the [example] , [example-debuginfo] , and [example-source] sections, type: When successful, the yum-config-manager --enable command displays the current repository configuration. Disabling a Yum Repository To disable a Yum repository, run the following command as root : yum-config-manager --disable repository where repository is the unique repository ID (use yum repolist all to list available repository IDs). Similarly to yum-config-manager --enable , you can use a glob expression to disable all matching repositories at the same time: yum-config-manager --disable glob_expression When successful, the yum-config-manager --disable command displays the current configuration.
