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  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 

          不需要做   <<<------|

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-$releasever - Base baseurl=http://mirrors.163.com/centos/6.0/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6 #released updates [updates] name=CentOS-$releasever - Updates baseurl=http://mirrors.163.com/centos/6.0/updates/$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/6.0/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/6.0/centosplus/$basearch/ gpgcheck=1 enabled=0
