linux CentOS 5.3 yum源配置过程详解（切实可用）

1.以root用户进入CentOS系统。

[root@xuxy ~]# cd /etc/yum.repos.d

2.备份repo

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

3.建立新的CentOS-Base.repo文件：（以CentOS 5.3为例）

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

内容如下:

现在可以yum了。^_^

如果不能运行，请加载

yum- 3.2. 19- 18.e15.centos.noarch.rpm

即执行命令

＃rpm -ivh yum- 3.2. 19- 18.e15.centos.noarch.rpm

如果还不能运行请下载 yum-metadata-parser-1.1.2-2.el5.i386.rpm 和 yum-3.2.19-18.el5.centos.noarch.rpm 此两个文件，并安装此文件

即执行命令

#rpm -ivh yum- 3.2. 19- 18.el5.centos.noarch.rpm

#rpm - ivh yum-metadata-parser- 1.1. 2- 2.el5.i386.rpm

这样就肯定能运行yum了，我亲自试验过的！！
