data download Source:
CentOS7
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
CentOS6
wget http://mirrors.163.com /.help/CentOS6-Base-163.repo
CentOS5
wget http://mirrors.163.com/.help/CentOS5-Base-163.repo
2, using ansible download repo
ansible webservers -m get_url -a "url=http://mirrors.163.com/.help/CentOS6-Base-163.repo dest=/etc/yum.repos.d"

用阿里云，只要下载aliyun的yum配置文件到/etc/yum.repos.d/，其它步骤一致
CentOS7
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
CentOS6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
CentOS5
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
