linux下配置yum源详解

本人使用的方法一，成功配置，方法二没测过，可以作为参考

方法一：

1.确保RHEL5中已经安装了yum

[plain] view plaincopy

1. [root@lvs-master ~]# rpm -qa |grep yum  
2. yum-metadata-parser-1.1.2-3.el5  
3. yum-updatesd-0.9-2.el5  
4. yum-3.2.22-26.el5  
5. yum-security-1.1.16-13.el5  
6. yum-rhn-plugin-0.5.4-15.el5  

2.修改源配置文件 ＃vim /etc/yum.repos.d/CentOS-Base.repo

(如果目录下没有.repo文件自己创建一个)

[plain] view plaincopy

1. [base]  
2. name=CentOS-5-Base  
3. #mirrorlist=http://mirrorlist.centos.org/?release=$releasever5&arch=$basearch&repo=os
