CentOS CD mount command and install software

Recently learned another command: Mount Mount command, we install the software, we directly hit the command install package name, but here is actually connected to install,

If you are using a disc, you should use the Mount command from your local installation.

Input: mount/dev/cdrom/mnt//NOTE: Mount the CD to the MNT directory under the root directory

2, CD/ETC/YUM.REPOS.D//notes:

2.1 mv Centos-base.repo Entos-base.repo.bak//Note: This can be deleted, or you can modify the file suffix

2.2 Vim Centos-media.repo

baseurl=file:///mnt///Note: Specify the Yum source location
