What is FreeRadius Server?

FreeRADIUS is a modular, high performance and highly customizable open source RADIUS server.

We will now install freeRADIUS on CentOS 7 Linux Server. We will install freeRADIUS from YUM repository. So, before going to start freeRADIUS installation, you should have CentOS 7 ready so that it can access CentOS Yum repository.
