redhat6.5 配置使用centos的yum源

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

​# wget http://mirrors./centos/6/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm​​​​# wget http://mirrors./centos/6/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm​​​​# wget http://mirrors./centos/6/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm​




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:


1

​# rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpm yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm​


4.更换yum源。使用163的源


1 2 3

​# cd /etc/yum.repos.d/​​​​# wget http://mirrors./.help/CentOS6-Base-163.repo​​​​# vi CentOS6-Base-163.repo​


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)
