1.确保RHEL5中已经安装了yum
[root@lvs-master ~]# rpm -qa |grep yum
yum-metadata-parser-1.1.2-3.el5
yum-updatesd-0.9-2.el5
yum-3.2.22-26.el5
yum-security-1.1.16-13.el5
yum-rhn-plugin-0.5.4-15.el5
cd /etc/yum.repos.d/ mv CentOS-Base.repo CentOS-Base.repo.bak wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo
运行上面三行代码,再vim CentOS-Base.repo 该文件内容如下:
[base]
