Question: If there is no network, how to use the Yum source.

Answer: Use CD to build Yum source

Build steps:

1. Mount CD

mount/dev/cdrom/mnt/cdrom/#挂载光盘

2, the network Yum source failure

Cd/etc/yum.repos.d/#进入yum源目录
MV Centos-base.repo Centos-base.repo.bak #修改yum源文件后缀名, making it ineffective

3, make the CD Yum source effective

VI Centos-media.repo

-[C6-media]
-name=centos-$releasever-media-
baseurl=file:///mnt/cdrom/	#地址为你自己的光盘挂载地址
-#        file:///media/cdrom/
-#        file:///media/cdrecorder/	#注释这两个不存在的地址
gpgcheck=1
enabled=0	# Change the enable=1 to enable=0 and let the Yum source configuration file take effect
gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-centos-6
