RHEL中yum环境设置

阅读更多

Ubuntu下的apt相当好用，可惜现在服务器的操作系统很少用到Ubuntu，大部分都是安装的Red Hat Enterprise Linux，RHEL的yum库要付给给Red Hat，所以需要把RHEL升级到CentOS，然后使用CentOS的免费yum库。

 

 

1.安装安全证书

rpm --import http://mirror.centos.org/centos-5/5/os/x86_64/RPM-GPG-KEY-CentOS-5

 

2.安装release package

rpm -Uvh http://mirror.centos.org/centos-5/5/os/x86_64/CentOS/centos-release-notes-5.8-0.x86_64.rpm

rpm -Uvh http://mirror.centos.org/centos-5/5/os/x86_64/CentOS/centos-release-5-8.el5.centos.x86_64.rpm

 

3.rpm -qa | grep yum

  卸载 原有的yum

 

4. 装上新CentOS的yum

rpm -Uvh http://mirror.centos.org/centos-5/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm

rpm -Uvh http://mirror.centos.org/centos-5/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm

 

强制安装

rpm -Uvh --nodeps http://mirror.centos.org/centos-5/5/os/x86_64/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm

 

5.更新

yum update

 

至此便可以正常使用yum来管理软件包了
