Red Hat SummitChapter 10. Managing custom software repositories
You can configure a repository in the /etc/dnf/dnf.conf file or in a .repo file in the /etc/yum.repos.d/ directory.
Define your repositories in the .repo file instead of /etc/dnf/dnf.conf.
The /etc/dnf/dnf.conf file contains the [main] section and can contain one or more repository sections ([<repository-ID>]) that you can use to set repository-specific options. The values you define in individual repository sections of the /etc/dnf/dnf.conf file override values set in the [main] section.
10.1. DNF repository options
The /etc/dnf/dnf.conf configuration file contains repository sections with a unique repository ID in brackets ([]). You can use such sections to define individual DNF repositories.
Repository IDs in [] must be unique.
For a complete list of available repository ID options, see the [<repository-ID>] OPTIONS section of the dnf.conf(5) man page on your system.
10.2. Adding a DNF repository
You can add a DNF repository to your system by using the dnf config-manager --add-repo command.
Procedure
Add a repository to your system:
# dnf config-manager --add-repo <repository_URL>Note that repositories added by this command are enabled by default.
Review and, optionally, update the repository settings that the previous command has created in the
/etc/yum.repos.d/<repository_URL>.repofile:# cat /etc/yum.repos.d/<repository_URL>.repo
Obtaining and installing software packages from unverified or untrusted sources other than Red Hat certificate-based Content Delivery Network (CDN) is a potential security risk, and can lead to security, stability, compatibility, and maintainability issues.
10.3. Enabling a DNF repository
You can enable a DNF repository added to your system by using the dnf config-manager command.
Procedure
Enable a repository:
# dnf config-manager --enable <repository_id>
10.4. Disabling a DNF repository
You can disable a DNF repository added to your system by using the dnf config-manager command.
Procedure
Disable a repository:
# dnf config-manager --disable <repository_id>
