给RHEL5.2 X86系统设置Centos的yum更新源

1、删除系统原有的RHN的yum包

 

rpm -e  yum-rhn-plugin-0.5.3-6.el5 rm  -f  /etc/yum.repos.d/rhel-debuginfo.repo

 

2、下载相关的centos包

 

wget http://ftp.nara.wide.ad.jp/pub/Linux/centos/5/os/i386/CentOS/centos-release-5-6.el5.centos.1.i386.rpm wget http://ftp.nara.wide.ad.jp/pub/Linux/centos/5/os/i386/CentOS/centos-release-notes-5.6-0.i386.rpm wget http://ftp.nara.wide.ad.jp/pub/Linux/centos/5/os/i386/CentOS/createrepo-0.4.11-3.el5.noarch.rpm wget http://ftp.nara.wide.ad.jp/pub/Linux/centos/5/os/i386/CentOS/yum-3.2.22-33.el5.centos.noarch.rpm wget http://ftp.nara.wide.ad.jp/pub/Linux/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm rpm -ivh centos-release-notes-5.6-0.i386.rpm rpm -ivh --force centos-release-5-6.el5.centos.1.i386.rpm rpm -ivh createrepo-0.4.11-3.el5.noarch.rpm rpm -ivh yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm rpm -Uvh yum-3.2.22-33.el5.centos.noarch.rpm

 

3、更改CentOS-Base.repo内容，内容如下：

 

[base] name=CentOS-5 - Base baseurl=http://centos.ustc.edu.cn/centos/5/os/i386/ gpgcheck=1 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 #released updates [update] name=CentOS-5 - Updates baseurl=http://centos.ustc.edu.cn/centos/5/updates/i386/ gpgcheck=1 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 #packages used/produced in the build but not released [addons] name=CentOS-5 - Addons baseurl=http://centos.ustc.edu.cn/centos/5/addons/i386/ gpgcheck=1 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 #additional packages that may be useful [extras] name=CentOS-5 - Extras baseurl=http://centos.ustc.edu.cn/centos/5/extras/i386/ gpgcheck=1 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-5 - Plus baseurl=http://centos.ustc.edu.cn/centos/5/centosplus/i386/ gpgcheck=1 enabled=0 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 #contrib - packages by Centos Users [contrib] name=CentOS-5 - Contrib baseurl=http://centos.ustc.edu.cn/centos/5/contrib/i386/ gpgcheck=1 enabled=0 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5

 

4、现在可以执行yum相关的命令了。

yum  list

 

5、此时，如果在安装一个包时，出现下面这个错误，是由于GPG没有导入造成:

 

6、针对这个问题，可以将上述的Centos-Base.repo中的gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5导入到gpg库中，使用命令导入：

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

 

此时，可以查看导入GPG的RPM-GPG-KEY-CentOS-5文件：

ls  /etc/pki/rpm-gpg/

 

7、此时再执行上面的yum安装时，就会一切OK了，如下图：

 

8、现在已经完全可以安装centos的yum源包了。^_^
