The main use of these four steps,
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
yum clean all
yum makecache
This article also refer http://www.cnblogs.com/J0der/p/5566610.html continue to repair yum source, specifically what step to solve the problem I do not know, anyway, then you can successfully install package of networking.
cd /etc/yum.repos.d
mkdir yum.repos.d
wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo
Presumably, the upper part to repair the problem.

# 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.

[root@cloud ~]# yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.6.6 (r266:84292, Feb 22 2013, 00:00:18)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)]
