one。 Deploy YUM software repository

To successfully use the YUM mechanism to update systems and software, you need a software repository (Repository) that contains various rpm installation package files, and the server that provides the software repository is also known as the "source" server. As long as the information such as the address of the software repository is correctly specified in the client, the software can be installed or updated through the corresponding "source" server.

YUM software repositories are usually released with the help of HTTP or FTP protocols, so that software source services can be provided to all clients in the network. In order to facilitate the client to query the software package and obtain the dependency information, it is necessary to provide warehouse data (repodata) in the software repository, in which the header information of all rpm packages under the directory is collected.
