RedHat系统下安装yum

一、前言

因为RedHat系统下的软件更新是RedHat公司的一项服务，必须用钱买的rhel系统，并且注册了RedHat的用户才能使用yum，要想免费使用yum，必须卸载原来的yum，安装centos的yum包。

二、卸载rhel的默认安装的yum包

查看yum包
rpm -qa|grep yum
卸载
rpm -qa|grep yum|xargs rpm -e --nodeps

三、下载新的yum包

64位linux系统下载安装包
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 32位linux系统下载安装包
wget  http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-3.2.22-40.el5.centos.noarch.rpm wget  http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm wget  http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-metadata-parser-1.1.2-4.el5.i386.rpm 然后进行安装
rpm -ivh yum-*
注意：yum和yum-fastestmirror相互依赖，所以同时安装即可。

四、下载yum的配置源

wget  http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo 下载到/etc/yum.repos.d/ 目录下面

五、配置yum

先进入到

#cd  /etc/yum.repos.d/里。把里面的文件改成备份文件，即在后面加.bak。

# mv /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.bak

# mv /etc/yum.repos.d/rpmforge.repo.rpmnew /etc/yum.repos.d/rpmforge.repo.rpmnew.bak
 

建立新的配置文件：

# cd /etc/yum.repos.d

# touch rhel-debuginfo.repo

# touch mirrors-rpmforge

# touch rpmforge.repo

 

往新的配置文件写东西：

[root@killgoogle ~]#vi rhel-debuginfo.repo

[base]

#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

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

修改第二个配置文件：

#vi mirrors-rpmforge
http://apt.sw.be/redhat/el5/en/$ARCH/dag http://archive.cs.uu.nl/mirror/dag.wieers/redhat/el5/en/$ARCH/dag http://ftp2.lcpe.uni-sofia.bg/freshrpms/pub/dag/redhat/el5/en/$ARCH/dag
#http://ftp.heanet.ie/pub/freshrpms/pub/dag/redhat/el5/en/$ARCH/dag
http://ftp-stud.fht-esslingen.de/dag/redhat/el5/en/$ARCH/dag http://mirror.cpsc.ucalgary.ca/mirror/dag/redhat/el5/en/$ARCH/dag http://mirrors.ircam.fr/pub/dag/redhat/el5/en/$ARCH/dag http://rh-mirror.linux.iastate.edu/pub/dag/redhat/el5/en/$ARCH/dag http://rpmfind.net/linux/dag/redhat/el5/en/$ARCH/dag http://wftp.tu-chemnitz.de/pub/linux/dag/redhat/el5/en/$ARCH/dag http://www.mirrorservice.org/sites/apt.sw.be/redhat/el5/en/$ARCH/dag
 

 

修改第三个配置文件：

# vi rpmforge.repo

# Name: RPMforge RPM Repository for Red Hat Enterprise 5 - dag

# URL: http://rpmforge.net/
[rpmforge]

name = Red Hat Enterprise $releasever - RPMforge.net - dag

#baseurl = http://apt.sw.be/redhat/el5/en/$basearch/dag
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge

enabled = 1

protect = 0

gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag

gpgcheck = 1

六、运行yum makecache生成缓存

#yum makecache

到此安装完毕。
