国内yum源的安装(163，阿里云，epel)
----阿里云镜像源
1、备份
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/
CentOS 5
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
或者
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
CentOS 6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
或者
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
CentOS 7
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
或者
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
3、之后运行命令生成缓存
yum clean all && yum makecache

参考1：https://yq.aliyun.com/articles/38561 CentOS6使用第三方YUM源（EPEL、RPMForge和RPMFusion）
写的比较详细，可以好好参考：
1、安装yum-priorities插件
2、CentOS默认源设置（一般设置CentOS-Base，设置为优先级最高1）
3、安装epel
4、安装rpmforge
5、安装rpmfusion
6、加载所有YUM源
yum list #列出所有第三方YUM源的软件包
参考2：https://www.cnblogs.com/imweihao/p/7357484.html 国内yum源的安装(163，阿里云，epel)
比较全。
参考3：官方源、镜像源汇总：https://www.cnblogs.com/clsn/p/8372108.html
总结了官方的很多源，比较好找。
