1. 挂载centos6.4 DVD镜像
[root@centos64 ~]# mount /dev/cdrom /mnt2. 安装vsftp软件,启动vsftpd服务,拷贝centos6.4 DVD内容到ftp的匿名用户某一目录。

===============以后碰到了如下问题:
以上方法只是解决了yum -y install XXXXX的 安装问题,但是对于 yum groupinstall 安装的时候,就会报错,如下:
[root@BG-DB:/etc/yum.repos.d]$yum grouplist

【centos5.X】需要如下方法执行:
[root@server202:/var/ftp/centos5.9-x86_64]$createrepo -g repodata/comps.xml . ##注意,这里和上面的不同,这个是组的数据库配置。3579/3579 - CentOS/xorg-x11-drv-cirrus-1.1.0-2.fc6.x86_64.rpm pm6_64.rpmSaving Primary metadataSaving file lists metadataSaving other metadata[root@server202:/var/ftp/centos5.9-x86_64]$【centos6.X】需要如下方法执行:
