RHEL7.0配置aliyun
1、创建一个目录，用于存放原来的yum信息。我这里没有yum，就不创建目录了。
[root@master ~]# cd /etc/yum.repos.d/
[root@master yum.repos.d]# ls
[root@master yum.repos.d]#
2、下载镜像源
阿里云官方镜像网站：https://developer.aliyun.com/mirror/
[root@master yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

[root@master yum.repos.d]# ls
CentOS-Base.repo
[root@master yum.repos.d]#
3、生成缓存
[root@master yum.repos.d]# yum makecache

最终repo文件如下：
# 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.
