在当我们安装CentOS 6.4而又不能联网时，那么我们的yum命令是用不了的，这是我们可以配置本地源使用yum命令
1.配置repo文件，
cd /etc/yum.repos.d
备份好原有的配置文件
mv CentOS-Base.repo CentOS-Base.repo.bak
mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.bak
mv CentOS-Vault.repo CentOS-Vault.repo.bak
mv CentOS-Media.repo CentOS-Media.repo.bak
创建新的配置文件 vim CentOS-Debuginfo.repo
[debug]
name=centos
baseurl=file:///mnt
enabled=1
gpgcheck=0
gpgkey=file:///mnt/RPM-GPG-KEY-RedHat-release
:wq 保存
2.配置yumRepo.py文件，
cd /usr/lib/Python2.6/site-packages/yum
vim yumRepo.py
将 remote = url + ‘/’ + relative
改为 remote = "/mnt" + '/' + relative
:wq 保存修改
3 配置iso挂载文件
mount /dev/cdrom /mnt
4 验证测试(使用vsftpd)
rpm -qa |grep vsftpd
yum list |grep vsftpd
[root@hsj2 yum]# yum list |grep vsftpd
vsftpd.i686 2.2.2-11.el6_3.1 @debug
yum install vsftpd.i686
[root@hsj2 yum]# yum install vsftpd.i686
