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.el

 

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.163.com/centos/6.5/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm

# wget http://mirrors.163.com/centos/6.5/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm
# wget http://mirrors.163.com/centos/6.5/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:

 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

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

 编辑文件,把文件里面的$releasever全部替换为版本号,即6.5(:1,$s/$releasever/6.5然后按enter建) 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)

# 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.

 5.清除原有缓存

 yum clean all

 重建缓存,以提高搜索安装软件的速度

 yum makecache

 6.更新系统

# yum update
