將解析請求轉發給DNS服務器：192.168.0.4
Forwarders { 192.168.0.4; };
SLAVE
在DNS（SLAVE）：
Vim /var/named/chroot/etc/named.conf
加入：
Zone “baidu.com” IN {
Type slave;
File “slave/baidu.com.zone”;
Master { 192.168.0.4; };
};
Zone “0.168.192.in-addr.arpa” IN {
Type slave;
File “slave/0.168.192.com.zone”;
Master { 192.168.0.4; };
};
注意：在服務器iptables加入：
vim /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT –p udp –-deport 53 –j ACCEPT
★
[root@client~]vim /etc/resolv.conf
Nameserver 192.168.0.1
