网易CentOS源使用帮助

1. 首先备份/etc/yum.repos.d/CentOS-Base.repo
   mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2. 下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)
   wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
   或curl http://mirrors.163.com/.help/CentOS7-Base-163.repo> CentOS7-Base-163.repo
   或WinSCP传上去

• CentOS7
• CentOS6
• CentOS5

3. 运行以下命令生成缓存
   yum clean all
   yum makecache

其它可以参考官方文档
