解决Redhat Linux5 yum出现This system is not registered with RHN

最近博主在学习Linux,菜鸟级别的的选手连装个Chrome都觉得难,悲了个催的……百度了很多教程,大多是类似的。博主的配置是在VM8下搭建的RHEL5.3 (Tikanga)版本,不知道什么原因,每次在输入yum install google-chrome-stable之后就会出现“This system is not registered with RHN”的错误提示,蛋疼不已。百度无果后,GG大神帮上忙了(搜索Redhat This system is not registered with RHN,会冒出很多国外大牛的文章)。

出现这个错误的原因是你的Linux木有花钱在红帽网络上注册^^,所以无法下载谷歌Chrome的软件包,解决方案可以使用从Redhat演化而来的免费Linux版本CentOS,通过CentOS的yum更新源来实现RHEL5的YUM功能。下面博主结合GG到的国外文章谈谈How to Install CentOS YUM on Redhat Linux RHEL5,以此来解决This system is not registered with RHN的问题。

1 check what yum package installed

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 remove all installed yum packages

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查看,无信息显示表示已经卸载完成。
3 download the centos packages from website

下载 CentOS YUM包,首先我们需要找到CentOS YUM的更新源,推荐的有(前三个适用于Redhat Linux5版本,最后一个适用于RHEL6的64位版本,当然不管是RHEL5还是RHEL6等等都可以从下面四个镜像网站中下载):

1.国外镜像源http://ftp.heanet.ie/pub/centos/5/os/i386/CentOS/
2.中国科技大学http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/
3.网易开源镜像http://mirrors.163.com/centos/5/os/i386/CentOS/
4.搜狐开源镜像http://mirrors.ustc.edu.cn/centos/6/os/x86_64/Packages/

接着我们就需要在终端里面输入以下命令进行下载(以博主的RHEL5.3为例,从中国科大下载镜像,下载的目录如果没设置的话就会默认是[root@localhost ~]# pwd显示的路径)

[root@localhost ~]# wget http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-
fastestmirror-1.1.16-21.el5.centos.noarch.rpm
[root@localhost ~]# wget http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-
metadata-parser-1.1.2-4.el5.i386.rpm
[root@localhost ~]# wget http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-
3.2.22-40.el5.centos.noarch.rpm
[root@localhost ~]# wget http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/
python-iniparse-0.2.3-6.el5.noarch.rpm
4 安装这所下载的四个包

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:

[root@localhost ~]# rpm -ivh  yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm 
yum-metadata-parser-1.1.2-4.el5.i386.rpm 
yum-3.2.22-40.el5.centos.noarch.rpm 
yum-3.2.22-40.el5.centos.noarch.rpm
//或者
[root@localhost ~]# rpm –ivh yum-*
5 download configure file

下载CentOS-Base.repo到/etc/yum.repos.d/文件夹里:

[root@localhost ~]# wget  http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo 
-O /etc/yum.repos.d/CentOS-Base.repo
[root@localhost ~]# wget  http://huangkeye-blog.googlecode.com/files/CentOS-Base.repo 
-O /etc/yum.repos.d/CentOS-Base.repo(以上这两个适用于RHEL版本5
[root@localhost ~]# wget  http://my-project-huangkeye.googlecode.com/files/CentOS-Base.repo 
-O /etc/yum.repos.d/CentOS-Base.repo(这个适用于RHEL版本6)

也可以直接进入vim修改该文件为以下内容:

[base]
name=CentOS-5 - Base
baseurl=http://centos.ustc.edu.cn/centos/5/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

#released updates
[update]
name=CentOS-5 - Updates
baseurl=http://centos.ustc.edu.cn/centos/5/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/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/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#additional packages that may be useful
[extras]
name=CentOS-5 - Extras
baseurl=http://centos.ustc.edu.cn/centos/5/extras/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

#additional packages that extend functionality of existing packages
[centosplus]

gpgcheck=1

gpgkey=http://mirror.centos.org/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/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

#packages in testing
[testing]
name=CentOS-5 - Testing
baseurl=http://centos.ustc.edu.cn/centos/5/testing/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
6 [选做]clear cache and rebuild

需要清除和重建cache:

[root@localhost ~]# yum clean metadata
[root@localhost ~]# yum clean dbcache
[root@localhost ~]# yum makecache
7 installation has been completed, testing
//安装成功,开始测试:
[root@localhost ~]# yum update
8 Yum百科 :
RHEL安装软件包管理器Yum(全称为 Yellow dog Updater, Modified)是一个在FedoraRedHat以及SUSECentOS中的Shell前端软件包管理器。基于RPM包管理,能够从指定的服务器自动下载RPM包并且安装,可以自动处理依赖性关系,并且一次安装所有依赖的软件包,无须繁琐地一次次下载、安装。
