4.查看repo文件
## vi CentOS-Base.repo

# The mirror system uses the connecting IP address of the client and the

# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.

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

Metadata Cache Created网上还有一个据说完善的方法，不过没有进行测试，有兴趣的同学可以测试一下
在所有mirrorlist前面加上#，并所有$releasever替换成6
sed -i '/mirrorlist/d' CentOS-Base.repo
sed -i 's/\$releasever/6/' CentOS-Base.repo
sed -i '/\ [addons\]/,/^$/d' CentOS-Base.repo
sed-i 's/RPM-GPG-KEY-CentOS-5/RPM-GPG-KEY-CentOS-6/' CentOS-Base.repo
