In fact, for CentOS DVD, the software provided inside is enough to meet our needs, and the software version in DVD is stable, and the download speed is fast. For learning CentOS, using CentOS DVD as the default yum source can greatly improve learning efficiency.

1. Create a mount directory for DVD

[root@localhost ~] # mkdir / media/CentOS

2. Mount CentOS DVD under Linux (virtual machine mount DVD should be able to do so)

[root@localhost] # mount-t auto / dev/cdrom / media/CentOS

3. View the relevant configuration files, and the directory is

[root@localhost ~] # ls-l / etc/yum.repos.d/

-rw-r--r--. 1 root root 1926 July 3 10:15 CentOS-Base.repo

-rw-r--r--. 1 root root 637 July 3 10:15 CentOS-Debuginfo.repo

-rw-r--r--. 1 root root 626 July 3 10:15 CentOS-Media.repo

4. Disable the network update method of yum, and simply change the default preferred CentOS-Base.repo to CentOS-Base.repo.bak.

[root@localhost yum.repos.d] # mv CentOS-Base.repo CentOS-Base.repo.bak

5. Configure the local yum source

[root@localhost ~] # vim / etc/yum.repos.d/CentOS-Media.repo

Set

[c6-media]

Name=CentOS-$releasever-Media

Baseurl= file:///media/CentOS/

File:///media/cdrom/

File:///media/cdrecorder/

Gpgcheck=1

Enabled=0

Modify to

[c6-media]

Name=CentOS-$releasever-Media

Baseurl= file:///media/CentOS/

Gpgcheck=1

Enabled=1

Baseurl is modified to the mount directory of DVD, and enabled=1 is enabled for local update mode.

Wq save exit

6. Clear the original yum information

[root@localhost ~] # yum clean all

Loaded plugins: fastestmirror

Cleaning up Everything

7. Check the DVD software list

[root@localhost yum.repos.d] # yum list

Loaded plugins: fastestmirror

Determining fastest mirrors

C6-media | 3.7 kB 00:00...

C6-media/primary_db | 3.3MB 00:00...

In this way, you will use DVD to install the software by default. If you want to restore the network installation mode, you can restore CentOS-Base.repo.bak by renaming it.
