.com
xingxing.com.
xingxing.com. IN NS ns1.xingxing.com.
IN NS ns2.xingxing.com.
ns1.xingxing.com. IN A 172.16.100.1
ns2.xingxing.com. IN A 172.16.100.2
dig -t A www.baidu.com @172.16.100.1
两台子域//配置主从
fin.xingxing.com. IN NS ns1.fin.xingxing.com.
fin.xingxing.com. IN NS ns2.fin.xingxing.com.
ns1.fin.xingxing.com. IN A 172.16.100.8
ns2.fin.xingxing.com. IN A 172.16.100.88
makert.xingxing.com. IN NS ns1.makert.xingxing.com.
ns1.makert.xingxing.com. IN A 172.16.100.9
配置步骤如下：
1- 在主DNS服务器中vi /var/named/xingxing.com.zone授权子域
vi /var/named/xingxing.com.zone
增加如下四行信息 增加两个子域fin.xingxing.com. market.xingxing.com.
in IN NS ns1.fin
ns1.fin IN A 192.168.1.3
market IN NS ns1.market
ns1.market IN A 192.168.1.33
2- 子域服务器配置
vi /etc/resolve.conf
//增加两行
nameserver 127.0.0.1
search fin.xingxing.com
网卡dns配置为本机子域的ip192.168.1.3
3- 安装bind 、bind-utils。
配置vi /var/named.rfc1912.conf
增加子域信息
zone "fin.xingxing.com" IN {
type master;
file "fin.xingxing.com.zone";
};
创建并配置fin.xingxing.com.zone文件注意文件权限
vi /var/named/fin.xingxing.com.zone
$TTL 86400
@ IN SOA ns1.fin.xingxing.com. root (
3 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
@ IN NS ns1.fin.xingxing.com.
@ IN MX 5 mail.fin.xingxing.com.
ns1 IN A 192.168.1.3
mail IN A 192.168.1.3
smtp IN A 192.168.1.3
pop3 IN A 192.168.1.3
pop IN A 192.168.1.3
4- 测试解析
//测试NS记录
dig -t NS fin.xingxing.com @192.168.1.3

配置转发
vi /etc/named.conf
forward first; //only 只找192.168.1.5 first 先找192.168.1.5，如果解析不了就找根
forwarders { 192.168.1.5; };
配置转发域指对配置的域就行转发
vi /etc/named.conf
zone "xingxing.com" IN {
type forward;
forward first;
forwarders { 192.168.1.5; };
};
