主服务器配置：

1.在/var/named/neo.zone里添加如下数据

...前面省略... SOA部分序号加大，其余不变

dep1.neo.com. IN NS dns.dep1.neo.com.

dns.dep1.neo.com. IN A 10.3.156.45

从服务器配置：

1.修改/etc/named.rfc1912.zones，假设文件名叫做dep1.neo.zone

zone "dep1.neo.com" IN {

type master;

file "dep1.neo.zone";

};

2.建立dep1.neo.zone

$TTL 86400

@ IN SOA dns.dep1.neo.com. root.neo.com. (

2013110901

2H

15M

1W

1D )

@ IN NS dns.dep1.neo.com.

dns IN A 10.3.156.45

www IN A 10.3.156.45

mail IN A 10.3.156.45

@ IN A 10.3.156.45

3.重启dns服务 service named restart
