解决问题：

定义转发域

代码语言：javascript
复制
父域配置(全局转发)

vim /etc/name.conf
options {
        listen-on port 53 { 10.201.106.128;127.0.0.1; };
        //listen-on-v6 port 53 { ::1; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { any; };
        recursion yes;
        forward first;                  ***
        forwarder { 10.201.106.2; };    ***

子域（区域转发），配置子域对zz.com的解析都转发给主服务器解析；

vim /etc/named.rfc1912.conf

zone "zz.com" IN {
        type forward;
        forward only;
        forwarders { 10.201.106.129; };
};

测试：在子域解析父域的域名
[root@zz ~]# dig -t A www.magedu.com @10.201.106.128

将子域的转发区域测试，将不能解析父域 ###、

复制
将转发域注释掉（/etc/named.rfc1912.conf）
[root@zz ~]# dig -t A www.zz.com @10.201.106.128

清空缓存
rndc flsuh

区域解析优先级大于全局解析

代码语言：javascript
复制
当子域服务器同时配置区域和全局解析配置时，解析内网的域名时找父域服务器，解析外网的域名时找外网DNS服务器；

配置：
全局解析配置：
[root@zz ~]# vim /etc/named.conf
forward first;
forwarders { 10.201.106.2; };
区域解析配置：
[root@zz ~]# vim /etc/named.rfc1912.zones 

zone "zz.com" IN {
        type forward;
        forward only;
        forwarders { 10.201.106.129; };
};

如果失败失败，可以看下named.conf里的一些安全配置改为no，两边服务器的安全配置都需要一模一样，不能一边项关闭，一边项注释；

bind的基础安全配置

acl的定义

代码语言：javascript
复制
[root@qq ~]# vim /etc/named.conf

acl slaves {
    10.201.106.129;
    127.0.0.1
};

只需要特定主机查询主域服务器的解析困

代码语言：javascript
复制
如果不在白名单，就算是自己服务器的其它IP也无法查询
/etc/named.rfc1912.conf
zone "zz.com" IN {
        type master;
        file "zz.com.zone";
        allow-query { 10.201.106.129; };

};

换成any，任意主机都可以查询；
zone "zz.com" IN {
    type master;
    file "zz.com.zone";
    allow-query { any; };

}; 子域发起查询主域名 [root@zz ~]# dig -t A www.zz.com @10.201.106.129

代码语言：javascript
复制

;; QUESTION SECTION:
;www.zz.com.            IN  A

;; ANSWER SECTION:
www.zz.com.     86400   IN  A   10.201.106.129

;; AUTHORITY SECTION:
zz.com.         86400   IN  NS  ns1.zz.com.
zz.com.         86400   IN  NS  ns2.zz.com.

只需许主域本机区域传送

代码语言：javascript
复制
未配置前子域可以从主域区域传送：
[root@zz ~]# dig -t AXFR zz.com @10.201.106.129

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.47.rc1.el6 <<>> -t AXFR zz.com @10.201.106.129
;; global options: +cmd
zz.com.         86400   IN  SOA ns1.zz.com. admin.zz.com. 2016042501 3600 300 259200 86400
zz.com.         86400   IN  NS  ns1.zz.com.
zz.com.         86400   IN  NS  ns2.zz.com.
*.zz.com.       86400   IN  A   10.201.106.129
ns1.zz.com.     86400   IN  A   10.201.106.129
ns2.zz.com.     86400   IN  A   10.201.106.128
ops.zz.com.     86400   IN  NS  ns1.ops.zz.com.
ns1.ops.zz.com.     86400   IN  A   10.201.106.128
www.zz.com.     86400   IN  A   10.201.106.129
zz.com.         86400   IN  SOA ns1.zz.com. admin.zz.c

主机配置/etc/named.rfc1912.conf进行限制
zone "zz.com" IN {
        type master;
        file "zz.com.zone";
        allow-query { any; };
        allow-transfer { 10.201.106.129; };

};

子域再测试，不能再传送了：
[root@zz ~]# dig -t AXFR zz.com @10.201.106.129

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.47.rc1.el6 <<>> -t AXFR zz.com @10.201.106.129
;; global options: +cmd
; Transfer failed.

主域可以正常传送区域
[root@qq ~]# dig -t AXFR zz.com @10.201.106.129

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.30.rc1.el6 <<>> -t AXFR zz.com @10.201.106.129

允许哪些主机递归

/etc/named.confg allow-recursion { ip; };

禁止更新区域数据库中的内容

代码语言：javascript
复制
zone "zz.com" IN {
        type master;
        file "zz.com.zone";
        allow-update { none; };
