1.為了方便起見，先切換到root用戶
2.先刪除rhel6自帶的yum
rpm -aq|grep yum|xargs rpm -e --nodeps
3.下載CentOS 6的yum
- wget http://mirrors.163.com/centos/6.0/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
- wget http://mirrors.163.com/centos/6.0/os/x86_64/Packages/yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm
- wget http://mirrors.163.com/centos/6.0/os/x86_64/Packages/yum-3.2.27-14.el6.centos.noarch.rpm
- wget http://mirrors.163.com/centos/6.0/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm
4.安裝這幾個rpm包,安裝的時候可能有依賴問題，多試幾次就可以了。
- 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 yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm
5.下載CentOS的repo源配置文件，我下載到的是CentOS 5的配置，www.linuxidc.com需要做些修改才能用在CentOS6上面。我已經改好了，用的是國內163的源鏡像。
- [base]
- name=CentOS-6 - Base
- repo=os
- baseurl=http://mirrors.163.com/centos/6/os/$basearch/

-
- #released updates

- baseurl=http://mirrors.163.com/centos/6/updates/$basearch/
- gpgcheck=1
- gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
-
- #packages used/produced in the build but not released

- #contrib - packages by Centos Users
- [contrib]

- gpgcheck=1
- enabled=0
- gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
6.然後把CentOS-Base.repo放到/etc/yum.repos.d/目錄下面
- mv ./CentOS-Base.rep /etc/yum.repos.d/
7.清除yum的緩存
8.現在應該就可以用了
試試：yum search nginx
