在Centos 上创建自动部署服务器的脚本

安装条件：

CentOS 系统

Centos 6.3 的 ISO 路径： /install/iso/CentOS-6.3-x86_64-bin-DVD1.iso。修改ISO为Centos 6.x版本的iso后就可以适用于6.x的各版本。就是下面这一行：

mount -o loop /install/iso/CentOS-6.3-x86_64-bin-DVD1.iso /media/cdrom

IP地址范围是172.17.80.0-172.17.95.254，掩码是255.255.240.0。部署服务器IP为172.17.80.250。可以根据需要修改相应的IP地址和DHCP配置。
