In CentOS 7, YUM (Yellowdog Updater Modified) is a package manager that simplifies software installation, update, and removal. To utilize YUM effectively, it’s crucial to set up and enable repositories. Here’s a step-by-step guide on how to create and enable YUM repositories in CentOS 7:
Create Repository Configuration File
First, create a new repository configuration file in the /etc/yum.repos.d/ directory. Use your preferred text editor (like vi or nano) to create a .repo file for your repository. For example:

gpgkey: URL to the GPG key for package verification.
Save and Exit
Save the changes made to the repository configuration file and exit the text editor.
Import GPG Key (Optional)
If your repository uses GPG signature verification (gpgcheck=1), import the GPG key using the following command:
