脚本实现自动创建DNS域名服务器

后面用到yum，请事先配置yum无误！

#!/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`

 

cat > /etc/named.conf << "EOF"

options {

directory "/var/named" ;

};

zone "." IN {

type hint;

file "named.ca";

};

zone "0.0.127.in-addr.arpa" IN {

file "named.local";

};

zone "DOMAIN" IN {

};

};
