redhat 7.2 可用的yum源， 亲自测试可以使用 ，使用过程：
1.卸载已经存在的yum: rpm -qa | grep yum | xargs rpm -e --nodeps
2.将yum 文件放到server中
3.执行rpm -ivh yum-*
4.创建repo文件：
#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.
