文章转载自http://www.cnblogs.com/shuaixf/archive/2011/11/30/2268496.html

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/6/os/x86_64/Packages/yum-3.2.27-14.el6.centos.noarch.rpm 
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm 
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm 
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm 

32位机器可以从http://mirrors.163.com/centos/6/os/i386/Packages/下载相应安装包安装

3.进行安装yum 

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm 
rpm -ivh yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm 
rpm -ivh yum-3.2.27-14.el6.centos.noarch.rpm um-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm  
注意最后两个包必需同时安装，否则会相互依赖 

4.更新repo文件

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

vi /etc/yum.repos.d/rhel-debuginfo.repo

内容为：

[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.163.com/centos/6.2/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6

#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.163.com/centos/6.2/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6

#packages used/produced in the build but not released
#[addons]
#name=CentOS-$releasever - Addons
#baseurl=http://mirrors.163.com/centos/$releasever/addons/$basearch/
#gpgcheck=1
#gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirrors.163.com/centos/6.2/extras/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://mirrors.163.com/centos/6.2/centosplus/$basearch/
gpgcheck=1
enabled=0

5、yum clean all 

6、yum install vim #测试一下可不可以用

【设置本地镜像作为yum源】

1、mkdir /mnt/cdrom

2   mount /dev/cdrom /mnt/cdrom  #挂着镜像，光盘

3  mkdir /home/redhat-iso

4  cp -Rf /mnt/cdrom/* /home/redhat-iso   #将光盘内的内容copy到某个路径下

5  vi /etc/yum.repos.d/rhel-debuginfo.repo  #编辑repo文件

添加一下内容：

[rhel_6_iso]
name=local iso 
baseurl=file:///home/redhat-iso/
gpgcheck=1
gpgkey=file:///home/redhat-iso/RPM-GPG-KEY-CentOS-6 #该处的gpgkey文件应该改成iso镜像中的文件名

 

二、yum常用命令
