The simplest way for Linux systems to configure local yum sources using ISO image files or discs

1. Assign Optical Drive

Select the local ISO system image file, or put the system installation disk in the optical drive. After that, you can see the Rhel-7.2-server disc icon on the desktop.

2. View the location of the optical drive mount

Use the df-h command to see where the optical drive or image file is mounted.

3, modify the local Yum source configuration file

[Email protected] ~]# Mv/etc/yum.repos.d/redhat.repo/etc/yum.repos.d/redhat.repo_bak---back up the original configuration file [[email protected]~]# Cat/etc/yum.repos.d/cdrom.repo---Create a new Cdrom.repo with the VI command and add the following [Cdrom]name=Cdrombaseurl= File:///run/media/root/rhel-7.2\ server.x86_64/----Note that the path cannot be directly used in the Mount path shown, because there are spaces in the middle, and you want to add a backslash escape.

4. Test if the Yum source is available

But the disadvantage of the local Yum source configured in this way is that you have to mount the ISO system image to the system, and if you delete the image file locally, the Yum command is unavailable. Another problem is that the next time you restart the system, it will automatically boot from the CD drive to the system installation screen.

The advantage is that the configuration is simple, fast, when you want to use the direct allocation of optical drive, do not want to remove, so it does not occupy storage space. Or if you have a large disk space, you can also copy the entire CD file to a directory in the system, if you modify the Cdrom.repo configuration file in the BaseURL parameter to the corresponding directory.
