RHEL5.4设置Centos的yum源

 RHEL5.4设置Centos的yum源

由于redhat的yum在线更新是收费的，如果没有注册的话不能使用，如果要使用，需将redhat的yum卸载后，重启安装，再配置其他源，以下为详细过程： 

1.删除redhat原有的yum 

rpm -aq|grep yum|xargs rpm -e --nodeps 

2.下载yum安装文件 

wget   http://mirrors.163.com/centos/5/os/i386/CentOS/yum-3.2.22-40.el5.centos.noarch.rpm

wget   http://mirrors.163.com/centos/5/os/i386/CentOS/yum-metadata-parser-1.1.2-4.el5.i386.rpm

wget   http://mirrors.163.com/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm

wget   http://mirrors.163.com/centos/5/os/i386/CentOS/yum-updatesd-0.9-5.el5.noarch.rpm

3.进行安装yum

#rpm -ivh  yum*.rpm 

4.更新repo 文件

wget http://mirrors.163.com/.help/CentOS5-Base-163.repo  -O CentOS-Base.repo

编辑CentOS-Base.repo把文件中$releasever替换为5。方法为： :s/$releasever/5/g

修改后如下：

[base]

name=CentOS-5 - Base - 163.com

baseurl=http://mirrors.163.com/centos/5/os/$basearch/

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

[updates]

name=CentOS-5 - Updates - 163.com

baseurl=http://mirrors.163.com/centos/5/updates/$basearch/

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

baseurl=http://mirrors.163.com/centos/5/contrib/$basearch/

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

 5.导入KEY文件，注意大小写 

rpm --import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 

6.测试：

 # yum clean all

# yum makecache
