RedHat的yum配置 以及 提示“This system is not registered with RHN” 的解决

一、RedHat的yum配置

1.确保RHEL5中已经安装了yum

[root@lvs-master ~]# rpm -qa |grep yum
yum-metadata-parser-1.1.2-3.el5
yum-updatesd-0.9-2.el5
yum-3.2.22-26.el5
yum-security-1.1.16-13.el5
yum-rhn-plugin-0.5.4-15.el5

2.修改源配置文件 #vim /etc/yum.repos.d/CentOS-Base.repo

[base]
name=CentOS-5-Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever5&arch=$basearch&repo=os
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
baseurl=http://ftp.sjtu.edu.cn/centos/5/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#released updates
[update]
name=CentOS-5-Updates
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=updates
baseurl=http://ftp.sjtu.edu.cn/centos/5/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#packages used/produced in the build but not released
[addons]
name=CentOS-5-Addons
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=addons

baseurl=http://ftp.sjtu.edu.cn/centos/5/addons/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#additional packages that may be useful
[extras]
name=CentOS-5-Extras
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=extras

baseurl=http://ftp.sjtu.edu.cn/centos/5/extras/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-5-Plus
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=centosplus
baseurl=http://ftp.sjtu.edu.cn/centos/5/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#contrib - packages by Centos Users
[contrib]
name=CentOS-5-Contrib
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=contrib
baseurl=http://ftp.sjtu.edu.cn/centos/5/contrib/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

# vi dag.repo
[dag]
name=Dag RPM Repository for RHEL5
baseurl=http://ftp.riken.jp/Linux/dag/redhat/el5/en/$basearch/dag/
enabled=1
gpgcheck=1
gpgkey=http://ftp.riken.jp/Linux/dag/packages/RPM-GPG-KEY.dag.txt

3. 导入key
 #rpm --import http://ftp.sjtu.edu.cn/centos/5/os/i386/RPM-GPG-KEY-CentOS-5

4. 运行,测试
 #yum update

5.#yum clean all

方法二:

# cd /etc/yum.repos.d/
#mv CentOS-Base.repo CentOS-Base.repo.bak
#wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo

该文件内容如下:

[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

#packages in testing
[testing]

gpgcheck=1

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



二、提示“This system is not registered with RHN”  的解决

1.卸载rhel的默认安装的yum包

查看yum包
rpm -qa|grep yum

卸载之
rpm -qa|grep yum|xargs rpm -e --nodeps

2.下载新的yum包

wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-3.2.22-40.el5.centos.noarch.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm 
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-4.el5.x86_64.rpm

上面3个rpm地址,可能会因为版本号的变动而变更,我们打开地址(http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/)然后在里面找到对应名称的下载即可。


并且安装之
rpm -ivh yum-*

注意:yum和yum-fastestmirror相互依赖,所以同时安装即可。


3.下载yum的配置源

wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo

4.修改配置源

把CentOS-Base.repo里面的url改成网易的yum源 http://mirrors.163.com/centos/5/os/x86_64/CentOS/ (有什么软件包,可以很清楚的看见),赞一下咱们的公司,就不用到国外的网站了,速度蛮快的。

5.全部更新

把修改后的CentOS-Base.repo复制到/etc/yum.repos.d/目录下,并在该目录下执行yum update进行统一更新,完成即可,这下安装软件什么的就比较方便了,不然的话,呵呵,那就有得你忙了。。。Linux软件包的依赖关系那是相当的头痛。
