下面是red hat 安装yum的方法
1.下载包 :wget http://yum.baseurl.org/download/2.0/yum-2.0.8-1.src.rpm .
固然也能够选择别的版本:http://yum.baseurl.org/download/2.0/node
2.进入目录进行安装 :
sudo rpmbuild --rebuild yum-2.0.8-1.src.rpm
cd /usr/src/RedHat/RPMS/noarch/
sudo rpm -ivh yum-2.0.8-1.noarch.rpmlinux
3.若是报错 使用：rpm -ivh –nodeps –replacefiles –force ＊.rpmcentos
4.配置yum更新地址 [base]
#name=Red Hat Linux $releasever - $basearch - Base
#baseurl=http://mirror.dulug.duke.edu/pub/yum-repository/redhat/$releasever/$basearch/
name=Red Hat Linux $releasever - $basearch - Base
baseurl= http://centos.ustc.edu.cn/centos/4/os/i386/
#[updates]
#name=Red Hat Linux $releasever - Updates
#baseurl=http://mirror.dulug.duke.edu/pub/yum-repository/redhat/updates/$releasever/
name=Red Hat Linux $releasever - Updates
baseurl= http://mirror.centos.org/centos/4/updates/i386/
[base] #name=Red Hat Linux $releasever - $basearch - Base
#baseurl=http://mirror.dulug.duke.edu/pub/yum-repository/redhat/$releasever/$basearch/
name=Red Hat Linux $releasever - $basearch - Base
baseurl= http://centos.ustc.edu.cn/centos/4/os/i386/ui
5.更新yum： yum update 等待更新完成就可使用yum了。url
