RHEL X86 64 6.0使用CentOS 6.0的yum源

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

1. wget http://mirrors.163.com/centos/6.0/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
2. wget http://mirrors.163.com/centos/6.0/os/x86_64/Packages/yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm
3. wget http://mirrors.163.com/centos/6.0/os/x86_64/Packages/yum-3.2.27-14.el6.centos.noarch.rpm
4. 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。

1. rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
2. rpm -ivh yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm
3. 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。

1. [base]
2. name=CentOS-6 - Base
3. repo=os
4. baseurl=http://mirrors.163.com/centos/6/os/$basearch/
5. gpgcheck=1
6. gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
8. #released updates
9. [update]
10. name=CentOS-6 - Updates
11. baseurl=http://mirrors.163.com/centos/6/updates/$basearch/
12. gpgcheck=1
13. gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
15. #packages used/produced in the build but not released
16. #[addons]
17. #name=CentOS-6 - Addons
18. #baseurl=http://mirrors.163.com/centos/5/addons/$basearch/
19. #gpgcheck=1
20. #gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
22. #additional packages that may be useful
23. [extras]
24. name=CentOS-6 - Extras
25. baseurl=http://mirrors.163.com/centos/6/extras/$basearch/
26. gpgcheck=1
27. gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
30. #additional packages that extend functionality of existing packages
31. [centosplus]
32. name=CentOS-6 - Plus
33. baseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/
34. gpgcheck=1
35. enabled=1
36. gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
38. #contrib - packages by Centos Users
39. [contrib]
40. name=CentOS-6 - Contrib
41. baseurl=http://mirrors.163.com/centos/6/contrib/$basearch/
42. gpgcheck=1
43. enabled=0
44. 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

1. mv ./CentOS-Base.rep /etc/yum.repos.d/

7.清除yum的緩存

1. yum clean all

8.現在應該就可以用了

試試：yum search nginx
