redhat6.5 配置使用centos的yum源

短命女 2022-08-04 13:45 178阅读 0赞

新安装了redhat6.5.安装后，登录系统，使用yum update 更新系统。提示：

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

无法更新。

redhat 默认自带的 yum 源需要注册，才能更新。我们想不花钱也可以更新，需要替换掉redhat的yum源。

**1.检查是否安装yum包**

查看RHEL是否安装了yum，若是安装了，那么又有哪些yum包：

\[root@localhost ~\]\# rpm -qa |grep yum

yum-metadata-parser-1.0-8.fc6

yum-3.0.1-5.el5

yum-rhn-plugin-0.4.3-1.el5

yum-updatesd-3.0.1-5.el5

**2 删除redhat自带的yum包**

卸载上面显示的所有yum包：

\[root@localhost ~\]\# rpm -qa|grep yum|xargs rpm -e --nodeps（不检查依赖，直接删除rpm包）

再用

\[root@localhost ~\]\# rpm -qa |grep yum

\[root@localhost ~\]\#

查看，无信息显示表示已经卸载完成。

3.下载新的yum包。使用Centos6.5的yum包

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div> 
    <div>
      2 
    </div> 
    <div>
      3 
    </div> </td> 
   <td> 
    <div> 
     <div> 
      <code>#&nbsp;wget&nbsp;http://mirrors.163.com/centos/6.5/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm</code> 
     </div> 
     <div> 
      <code>#&nbsp;wget&nbsp;http://mirrors.163.com/centos/6.5/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm</code> 
     </div> 
     <div> 
      <code>#&nbsp;wget&nbsp;http://mirrors.163.com/centos/6.5/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

安装yum软件包

注意:单个的安装包可能会依赖其它包（例如yum和yum-fastestmirror会相互依赖），所以我们可以把所有这些包放在一起，用一行命令将它们同时安装即可：

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div> </td> 
   <td> 
    <div> 
     <div> 
      <code>#&nbsp;rpm&nbsp;-ivh&nbsp;yum-metadata-parser-1.1.2-16.el6.i686.rpm&nbsp;yum-3.2.29-40.el6.centos.noarch.rpm&nbsp;yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

4.更换yum源。使用163的源

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div> 
    <div>
      2 
    </div> 
    <div>
      3 
    </div> </td> 
   <td> 
    <div> 
     <div> 
      <code>#&nbsp;cd&nbsp;/etc/yum.repos.d/</code> 
     </div> 
     <div> 
      <code>#&nbsp;wget&nbsp;&nbsp;http://mirrors.163.com/.help/CentOS6-Base-163.repo</code> 
     </div> 
     <div> 
      <code>#&nbsp;vi&nbsp;CentOS6-Base-163.repo</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

编辑文件，把文件里面的$releasever全部替换为版本号，即6.5 最后保存！或者直接把下面的内存拷贝到CentOS6-Base-163.repo文件中即可（已经修改好）
