8.4.2. Setting [repository] Options

The [repository] sections, where repository is a unique repository ID such as my_personal_repo (spaces are not permitted), allow you to define individual Yum repositories. To avoid conflicts, custom repositories should not use names used by Red Hat repositories.
The following is a bare-minimum example of the form a [repository] section takes: 
[repository]
name=repository_name
baseurl=repository_url
Every [repository] section must contain the following directives:
name=repository_name
…where repository_name is a human-readable string describing the repository.
baseurl=repository_url
…where repository_url is a URL to the directory where the repodata directory of a repository is located:
  • If the repository is available over HTTP, use: http://path/to/repo
  • If the repository is available over FTP, use: ftp://path/to/repo
  • If the repository is local to the machine, use: file:///path/to/local/repo
  • If a specific online repository requires basic HTTP authentication, you can specify your user name and password by prepending it to the URL as username:password@link. For example, if a repository on http://www.example.com/repo/ requires a user name of “user” and a password of “password”, then the baseurl link could be specified as http://user:password@www.example.com/repo/.
Usually this URL is an HTTP link, such as: 
baseurl=http://path/to/repo/releases/$releasever/server/$basearch/os/
Note that Yum always expands the $releasever, $arch, and $basearch variables in URLs. For more information about Yum variables, see Section 8.4.3, “Using Yum Variables”.
Another useful [repository] directive is the following:
enabled=value
…where value is one of:
0 — Do not include this repository as a package source when performing updates and installs. This is an easy way of quickly turning repositories on and off, which is useful when you desire a single package from a repository that you do not want to enable for updates or installs.
1 — Include this repository as a package source.
Turning repositories on and off can also be performed by passing either the --enablerepo=repo_name or --disablerepo=repo_name option to yum, or through the Add/Remove Software window of the PackageKit utility.
Many more [repository] options exist. For a complete list, see the [repository] OPTIONS section of the yum.conf(5) manual page.
