RedHat用CentOS系统源

RedHat 无法使用官方的更新源，于是不得不将RedHat的官方源替换成CentOS的开源源，下面是具体的操作步骤：

1、更换RedHat的yum程序：

1. [root@leekwen]#cat/etc/issue
2. RedHatEnterpriseLinuxServerrelease5.5(Tikanga)
3. Kernel\ronan\m
5. [root@leekwen]#rpm-qa|grepyum
6. [root@leekwen]#rpm-eyum-3.2.22-20.el5--nodeps
7. [root@leekwen]#rpm-eyum-updatesd-0.9-2.el5--nodeps
8. [root@leekwen]#rpm-eyum-security-1.1.16-13.el5--nodeps
9. [root@leekwen]#rpm-eyum-Metadata-parser-1.1.2-3.el5--nodeps
10. [root@leekwen]#rpm-eyum-rhn-plugin-0.5.4-13.el5--nodeps

2、下载CentOS的yum程序（这里我的是32bit的服务器，如果64位的，请自行修改下载路径）：

1. [root@leekwen]#wget-chttp://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-3.2.22-40.el5.centos.noarch.rpm
2. [root@leekwen]#wget-chttp://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
3. [root@leekwen]#wget-chttp://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-Metadata-parser-1.1.2-4.el5.i386.rpm

3、安装CentOS的yum程序：

1. [root@leekwen]#rpm-ivhyum-3.2.22-40.el5.centos.noarch.rpmyum-fastestmirror-1.1.16-21.el5.centos.noarch.rpmyum-Metadata-parser-1.1.2-4.el5.i386.rpm

4、修改CentOS的yum源：

1. [root@leekwen]#cd/etc/yum.repos.d/
2. [root@leekwen]#cprhel-debuginfo.reporhel-debuginfo.repo.bak
3. [[email protected]]#echo>rhel-debuginfo.repo
4. [[email protected]]#catrhel-debuginfo.repo
5. [base]
6. name=CentOS-5-Base
7. repo=os
8. baseurl=http://centos.ustc.edu.cn/centos/5/os/$basearch/
9. gpgcheck=1
10. gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
11. [update]
12. name=CentOS-5-Updates
13. baseurl=http://centos.ustc.edu.cn/centos/5/updates/$basearch/
14. gpgcheck=1
15. gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
16. [addons]
17. name=CentOS-5-Addons
18. baseurl=http://centos.ustc.edu.cn/centos/5/addons/$basearch/
19. gpgcheck=1
20. gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
21. [extras]
22. name=CentOS-5-Extras
23. baseurl=http://centos.ustc.edu.cn/centos/5/extras/$basearch/
24. gpgcheck=1
25. gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
26. [centosplus]
27. name=CentOS-5-Plus
28. baseurl=http://centos.ustc.edu.cn/centos/5/centosplus/$basearch/
29. gpgcheck=1
30. enabled=0
31. gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
32. [contrib]
33. name=CentOS-5-Contrib
34. baseurl=http://centos.ustc.edu.cn/centos/5/contrib/$basearch/
35. gpgcheck=1
36. enabled=0
37. gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5

5、执行yum升级即可：

1. [root@leekwen]#yumupdate
