4.查看repo文件
## vi CentOS-Base.repo
# CentOS-Base.repo

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

5.查看6.7的readmew文件,还是有些表变化发现小版本不再进行更新
This directory (and version of CentOS) is deprecated. For normal users,
you should use /6/ and not /6.7/ in your path. Please see this FAQ
concerning the CentOS release scheme:
If you know what you are doing, and absolutely want to remain at the 6.7
level, go to http://vault.centos.org/ for packages.
Please keep in mind that 6.0, 6.1, 6.2, 6.3, 6.4 , 6.5, 6.6 and 6.7 no longer gets any updates, norany security fix's..
根据repo文件变量的变化，可以修改repo文件把所有$releasever替换成6
执行替换操作
#sed -i 's/\$releasever/6/' CentOS-Base.repo
6.清理并重新生成yum缓存
# yum clean all
