替換 RHEL5的yum源爲CentOS5源，親測線上系統可用

 

最近安裝nagios+pnp，各種依賴包啊。rrdtool腫麼裝的這麼費勁，後來實在扛不住了，還是修改rhel的源吧，把yum源搞成centos的不就ok了！哈哈。然後就從網上一頓猛搜，發現“Ayou”老師的文章很靠譜，很有幫助，這裏是看“Ayou”老師的文章搭出來的。雖然不是太難，但是找這個CentOS-Base.repo還是要靠“ayou”老師的文章，所以，感謝下“Ayou”老師。順便推薦“Ayou”老師的博客，有很多很多好的文章，篇幅很短，但很精練。

由於我的系統環境是x86_64的，“Ayou”老師的路徑是i386的，所以稍微改了一點Ayou老師源地址的路徑，還有一點就是把gpgkey的路徑換成了163的路徑，因爲感覺每次訪問gpgkey都要去國外的服務器跑一圈是不是有點繞了。當然把這個gpgkey放在本地也是合適的，但是，個人認爲在沒有互聯網訪問的情況下，yum源本身就是無法連通的，這個gpgkey也確實就沒有必要存在，所以這裏就沒有拿回本地來。

1、卸載掉RHEL原有的yum包

rpm -aq|grep yum|xargs rpm -e --nodeps

2、下載centos的yum安裝文件

wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm
wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-3.2.22-39.el5.centos.noarch.rpm
wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm
wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm

也可用此地址：
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-3.2.22-39.el5.centos.noarch.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
wget http://sudone.com/download/CentOS-Base.repo -O /etc/yum.repos.d/CentOS-Base.repo

key文件位置可選：
http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-5
http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5

3、安裝yum軟件包

rpm -ivh --nodeps \
# python-iniparse-0.2.3-4.el5.noarch.rpm \
yum-3.2.22-39.el5.centos.noarch.rpm \
yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm \
yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm

4、添加配置文件

wget http://sudone.com/download/CentOS-Base.repo -O /etc/yum.repos.d/CentOS-Base.repo

5、以防萬一，配置文件全文如下

# cat /etc/yum.repos.d/CentOS-Base.repo

6、萬事大吉，可以測試了

以下代碼爲展示，不用敲，只爲驗證yum是否能連到yum源上。經過下面測試已經可以顯示包了，ok。哈哈。配置完成，
