在/etc/yum.repos.d/目录下,有两个文件
CentOS-Base.repo和CentOS-Media.repo
其中CentOS-Base.repo记录着网络上的yum源的地址和路径信息等
CentOS-Media.repo记录着可以从本地作为yum源的介质和路径。其中还有这样一个说明:
# CentOS-Media.repo
#
# This repo is used to mount the default locations for a CDROM / DVD on
# CentOS-5. You can use this repo and yum to install items directly off the
# DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
# yum --enablerepo=c5-media [command]
#
# or for ONLY the media repo, do this:
#
# yum --disablerepo=* --enablerepo=c5-media [command]

觉得自己的光盘的源足够用了。不需要网络源,或者没有网络。
可以使用yum --disablerepo=/* --enablerepo=c5-media [command]
但是使用命令时如果这样
[root@centos yum.repos.d]# yum --enablerepo=c5-media

You need to give some command

这不是一个完整的命令,须在后面加上要执行的命令。这部分只是告诉你这条yum命令允许使用本地media介质的源而已。正确的命令如下:
[root@centos cdrom]# yum --disablerepo=* --enablerepo=c5-media update
