EPEL (Extra Packages for Enterprise Linux) is a project built by the Fedora community to provide high-quality software packages for RHEL and derivative distributions such as CentOS. Loaded with Epel, as in Fedora, you can install a lot of software, common software, or some popular software, such as the popular Nginx, OpenVPN and so on, by using the Yum install package name. You can use Epel to install updates easily.
