国内镜像地址：

http://mirrors.163.com/centos/ 。（网易）

我们就用 http://mirrors.163.com/centos/ 网易）来修改配置文件

方法一：

#先备份配置文件

cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.save

#修改配置文件（安（i）键进入插入模式进行修改）
vi /etc/yum.repos.d/CentOS-Base.repo
#配置文件如下修改：

# 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.
  #

 #修改完成后 安 （ESC）键 退出 插入模式 输入 (:wq) 保存退出

上面的修改就是把mirrorlist注释掉，将baseurl改成ustc.edu.cn的镜像地址。

方法二：

#先备份配置文件

cd /etc/yum.repos.d/

mv CentOS-Base.repo CentOS-Base.repo.save

wget http://mirrors.163.com/.help/CentOS-Base-163.repo

mv CentOS-Base-163.repo CentOS-Base.repo
