A software repository or “repo” is a central location for keeping and maintaining RPM software packages for Redhat Linux distribution, from which users can download and install packages on their Linux servers.
Repositories are generally stored on a public network, which can be accessed by multiple users on the internet. However, you can create your own local repository on your server and access it as a single user or allow access to other machines on your local LAN (Local Area Network) using HTTP web server.
