脚本实现自动创建DNS域名服务器
前提：保证yum可以正常使用！
#!/bin/bash
read -p "Please input your domain name:" DOMAIN
read -p "Please input your IPaddress:" NET
hostname www.$DOMAIN
yum install bind caching-nameserver -y
a=`echo $NET |cut -d"." -f1`
b=`echo $NET |cut -d"." -f2`
c=`echo $NET |cut -d"." -f3`
d=`echo $NET |cut -d"." -f4`
