2.编辑CentOS-Base.repo,填入以下内容

3.从http://centos.ustc.edu.cn/centos/5.4/os/i386/CentOS/下载以下文件并安装 
yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm 
yum-3.2.22-20.el5.centos.noarch.rpm 
yum-updatesd-0.9-2.el5.noarch.rpm 

或者找个FTP站点用wget下载： 
#wget ftp://ftp.pdc.kth.se/pub/bambi/centos/5.4/os/i386/CentOS/yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm 
#wget ftp://ftp.pdc.kth.se/pub/bambi/centos/5.4/os/i386/CentOS/yum-3.2.22-20.el5.centos.noarch.rpm 
#wget ftp://ftp.pdc.kth.se/pub/bambi/centos/5.4/os/i386/CentOS/yum-updatesd-0.9-2.el5.noarch.rpm 

#rpm -ivh yum*.rpm 


4.如果http://centos.ustc.edu.cn/centos这个服务器的CentOS映像不够快的话用自己适合的服务器替换，可以用IE上去先看看 

5.导入KEY文件，注意大小写 
rpm --import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 

6.测试下 
#yum list
