修改CentOS默认yum源为国内yum镜像源

1、首先备份系统自带yum源配置文件/etc/yum.repos.d/CentOS-Base.repo

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p><code>[root@localhost&nbsp;~]</code><code>#&nbsp;mv&nbsp;/etc/yum.repos.d/CentOS-Base.repo&nbsp;/etc/yum.repos.d/CentOS-Base.repo.backup</code></p> </td> 
  </tr> 
 </tbody> 
</table>

2、进入yum源配置文件所在的文件夹

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p><code>[root@localhost&nbsp;~]</code><code>#&nbsp;cd&nbsp;/etc/yum.repos.d/</code></p> </td> 
  </tr> 
 </tbody> 
</table>

3、下载163的yum源配置文件到上面那个文件夹内

CentOS7

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p><code>[root@localhost&nbsp;yum.repos.d]</code><code>#&nbsp;wget&nbsp;http://mirrors.163.com/.help/CentOS7-Base-163.repo</code></p> </td> 
  </tr> 
 </tbody> 
</table>

CentOS6

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p><code>[root@localhost&nbsp;yum.repos.d]</code><code>#&nbsp;wget&nbsp;http://mirrors.163.com/.help/CentOS6-Base-163.repo</code></p> </td> 
  </tr> 
 </tbody> 
</table>

CentOS5

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p><code>[root@localhost&nbsp;yum.repos.d]</code><code>#&nbsp;wget&nbsp;http://mirrors.163.com/.help/CentOS5-Base-163.repo</code></p> </td> 
  </tr> 
 </tbody> 
</table>

4、运行yum makecache生成缓存

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p><code>[root@localhost&nbsp;yum.repos.d]</code><code>#&nbsp;yum&nbsp;makecache</code></p> </td> 
  </tr> 
 </tbody> 
</table>

5、这时候再更新系统就会看到以下mirrors.163.com信息

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> <p>2</p> <p>3</p> <p>4</p> <p>5</p> <p>6</p> </td> 
   <td> <p><code>[root@localhost&nbsp;yum.repos.d]</code><code>#&nbsp;yum&nbsp;-y&nbsp;update</code></p> <p><code>已加载插件：fastestmirror,&nbsp;refresh-packagekit,&nbsp;security</code></p> <p><code>设置更新进程Loading&nbsp;mirror&nbsp;speeds&nbsp;from&nbsp;cached&nbsp;hostfile</code></p> <p><code>*&nbsp;base:&nbsp;mirrors.163.com</code></p> <p><code>*&nbsp;extras:&nbsp;mirrors.163.com</code></p> </td> 
  </tr> 
 </tbody> 
</table>

  </tr> 
 </tbody> 
</table>

CentOS6

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p><code>[root@localhost&nbsp;~]</code><code>#&nbsp;wget&nbsp;-O&nbsp;/etc/yum.repos.d/CentOS-Base.repo&nbsp;http://mirrors.aliyun.com/repo/Centos-6.repo</code></p> </td>

CentOS5

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p><code>[root@localhost&nbsp;~]</code><code>#&nbsp;wget&nbsp;-O&nbsp;/etc/yum.repos.d/CentOS-Base.repo&nbsp;http://mirrors.aliyun.com/repo/Centos-5.repo</code></p> </td> 
  </tr>

   <td> <p><code>[root@localhost&nbsp;~]</code><code>#&nbsp;yum&nbsp;-y&nbsp;update</code></p> <p><code>已加载插件：fastestmirror,&nbsp;refresh-packagekit,&nbsp;security</code></p> <p><code>设置更新进程Loading&nbsp;mirror&nbsp;speeds&nbsp;from&nbsp;cached&nbsp;hostfile</code></p> <p><code>*&nbsp;base:&nbsp;mirrors.aliyun.com</code></p> <p><code>*&nbsp;extras:&nbsp;mirrors.aliyun.com</code></p> <p><code>*&nbsp;updates:&nbsp;mirrors.aliyun.com</code></p> </td>
