Yum is a software package manager that installs, updates, and removes packages on RPM-based systems. It automatically computes dependencies and figures out what things should occur to install packages. yum makes it easier to maintain groups of machines without having to manually update each one using rpm.
Adding a Yum Repository
To define a new repository, you can add a .repo file in the /etc/yum.repos.d/ directory. All files with the .repo file extension in this directory are read by yum.
You can add it using commandline.
yum-config-manager --add-repo repository_url
yum-config-manager --add-repo https://www.eazylinux.com/eazylinux.repo note: the url is a test url, use the respective url from the repository.
Disable / Enable Repo
Change the following line in the repo file for the respective repository to disable it.
enabled=0 [ 0 - Disabled, 1 - enabled ]
