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:
~]# yum-config-manager --add-repo http://www.example.com/example.repo
Loaded plugins: product-id, refresh-packagekit, subscription-manager
adding repo from: http://www.example.com/example.repo
grabbing file http://www.example.com/example.repo to /etc/yum.repos.d/example.repo
example.repo | 413 B 00:00
repo saved to /etc/yum.repos.d/example.repo
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:
~]# yum-config-manager --enable example\*
Loaded plugins: product-id, refresh-packagekit, subscription-manager
============================== repo: example ==============================
[example]
bandwidth = 0
base_persistdir = /var/lib/yum/repos/x86_64/6Server
baseurl = http://www.example.com/repo/6Server/x86_64/
cache = 0
cachedir = /var/cache/yum/x86_64/6Server/example
[output truncated]
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.
