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：
