所有操作均在192.168.1.104上进行

一、安装bind9：

yum install -y bind

二、修改配置文件：

cp /etc/named.conf{,.back}              //先做备份

vim /etc/named.conf

三、启动服务：

chkconfig --level 35 named on          //设置开机启动

service named start

验证：

dig -t A www.souhu.com @192.168.1.104      //在192.168.1.0/24主机上操作

dig -t A www.sina.com @192.168.1.104     //在非192.168.1.0/24主机上操作

附：
