YUM Library installation configuration

Role of the yum Library: ignore the dependency between installation packages and install the rpm package in a centralized manner.

Classification: divided into local YUM (file) and network YUM (ftp, http)

Repository configuration file:/etc/yum. repos. d/*. repo

Case: local YUM configuration

First, copy the image file to a separate folder. Do not use the directly mounted folder to complete the operations. Go to the YUM repository to configure the YUM library and make the common yum configuration into a yum library file.
