4、获取阿里云repo
[root@localhost yum]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ll
total
-rw-r--r--. root root Apr : redhat.repo
[root@localhost yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo

5、替换repo里的版本号
[root@localhost yum.repos.d]# sed -i 's/$releasever/7/g' /etc/yum.repos.d/Centos-.repo
[root@localhost yum.repos.d]#
6、清理，重建缓存，查看repolist
[root@localhost yum.repos.d]# yum clean all
