linux CentOS 5.3 yum源配置過程詳解（切實可用）

1.以root使用者進入CentOS系統。

[root@xuxy ~]# cd /etc/yum.repos.d

2.備份repo

[root@xuxy yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak

3.建立新的CentOS-Base.repo檔案：（以CentOS 5.3為例）

[root@xuxy yum.repos.d]#vi CentOS-Base.repo

內容如下:

現在可以yum了。^_^

如果不能運行，請載入

yum-3.2.19-18.e15.centos.noarch.rpm

即執行命令

＃rpm -ivh yum-3.2.19-18.e15.centos.noarch.rpm

如果還不能運行請下載 yum-metadata-parser-1.1.2-2.el5.i386.rpm 和 yum-3.2.19-18.el5.centos.noarch.rpm 此兩個檔案，並安裝此檔案

即執行命令

#rpm -ivh yum-3.2.19-18.el5.centos.noarch.rpm

#rpm - ivh yum-metadata-parser-1.1.2-2.el5.i386.rpm

這樣就肯定能運行yum了，我親自實驗過的！！
