In this recipe, we will investigate the task of preparing YUM to manage additional repositories by installing a plugin known as YUM priorities. YUM has the ability to search, remove, install, retrieve, and update packages from various remote locations. Such features make YUM a powerful tool, but if you ever decide to add an additional third-party repository, there is a chance that conflicts will render the system unstable. Stability is one of the many advantages of using the CentOS operating system, and it is the purpose of this recipe to show you how this confidence can be maintained while simultaneously allowing for the addition of new repositories.
To complete this recipe, you will require a working installation of the CentOS 7 operating system with root privileges, a console-based text editor of your choice, and a connection to the Internet in order to facilitate the download of additional packages.
