最近需要在 RHEL 上安装 KVM,但是 RHEL 上安装需要额外的 Extra CD,还是 yum 直接安装方便。但是我们不是 RHEL 的付费用户啊。在网上 Google 一下找到好多方法,无外乎修改为 CentOS 源,更新 yum,导入 Key。以下是我找到并试验下来最简单的方法。
- 在 /etc/yum.repos.d/ 目录下新建一个文件 CentOS-Base.repo;
vim /etc/yum.repos.d/CentOS-Base.repo
- 复制以下内容并保存;
[base] name=CentOS-5 - Base #mirrorlist=http://mirrorlist.centos.org/?release=$releasever5&arch=$basearch& repo=os #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ baseurl=http://ftp.sjtu.edu.cn/centos/5/os/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #released updates [update] name=CentOS-5 - Updates #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=updates baseurl=http://ftp.sjtu.edu.cn/centos/5/updates/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #packages used/produced in the build but not released [addons] name=CentOS-5 - Addons #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=addons baseurl=http://ftp.sjtu.edu.cn/centos/5/addons/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #additional packages that may be useful [extras] name=CentOS-5 - Extras #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=extras baseurl=http://ftp.sjtu.edu.cn/centos/5/extras/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-5 - Plus #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=centosplus baseurl=http://ftp.sjtu.edu.cn/centos/5/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #contrib - packages by Centos Users [contrib] name=CentOS-5 - Contrib #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=contrib baseurl=http://ftp.sjtu.edu.cn/centos/5/contrib/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5
- 导入 Key。
64位: rpm --import http://ftp.sjtu.edu.cn/centos/5.4/os/x86_64/RPM-GPG-KEY-CentOS-5
32位: rpm --import http://ftp.sjtu.edu.cn/centos/5.4/os/i386/RPM-GPG-KEY-CentOS-5
- 执行 yum makecache。可使用 yum list 查看。
现在可以享受免费的 RHEL 啦。注意 yum update 会将系统更新成 CentOS。
