一：分离解析

1：实验环境部署

1：为dns服务器添加两个网卡，并按上图设置各个主机的网络桥接

DNS服务器的主机名设置为ns1

ns1的ens33网卡的桥接不变（NAT模式）------->内网客户机192.168.10.106（NAT模式）

ns1的ens36网卡桥接到仅主机模式------>外网客户机172.16.16.106，桥接为仅主机模式

备注：

用106主机做内网客户机

win10主机做外网客户机

2：用ifconfig命令查看网卡的名称

3：修改两个网卡的IP地址
两个网卡的参数如下：

[root@localhost network-scripts]# vim ifcfg-ens33

TYPE=Ethernet

PROXY_METHOD=none

BROWSER_ONLY=no

BOOTPROTO=static

IPADDR=192.168.10.101

NETMASK=255.255.255.0

GATEWAY=192.168.10.254

DNS1=114.114.114.114

DNS2=8.8.8.8

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_FAILURE_FATAL=no

IPV6_ADDR_GEN_MODE=stable-privacy

NAME=ens33

DEVICE=ens33

ONBOOT=yes

[root@localhost network-scripts]# vim ifcfg-ens36

TYPE=Ethernet

PROXY_METHOD=none

BROWSER_ONLY=no

BOOTPROTO=static

IPADDR=173.16.16.101

NETMASK=255.255.255.0

#GATEWAY=192.168.10.254

DNS1=114.114.114.114

DNS2=8.8.8.8

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_FAILURE_FATAL=no

IPV6_ADDR_GEN_MODE=stable-privacy

NAME=ens36

DEVICE=ens36

ONBOOT=yes

[root@localhost ~]# systemctl restart network：安装bind

2：安装软件包

[ro2ot@localhost ~]# hostnamectl set-hostname ns1

[root@localhost ~]# bash

[root@ns1 ~]# systemctl stop firewalld

[root@ns1 ~]# setenforce 0

[root@ns1 ~]# yum -y install bind

3：配置文件的修改

1：主配置文件

[root@ns1 ~]# vim /etc/named.conf

options {

        listen-on port 53 { any; };

        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";

        recursing-file  "/var/named/data/named.recursing";

        secroots-file   "/var/named/data/named.secroots";

        allow-query     { any; };

}；

#zone "." IN {

#       type hint;

#       file "named.ca";

#};

view "LAN" {

        match-clients { 192.168.10.0/24; };

        zone "bt.com" IN {

        type master;

        file "lan.bt.com.zone";

        };

};

view "WAN" {

        match-clients { any; };

        zone "bt.com" IN {

        type master;

        file "wan.bt.com.zone";

        };

};

#include "/etc/named.rfc1912.zones";

#include "/etc/named.root.key";

2：区域文件的设置

（1）内部区域文件

[root@ns1 ~]# cd /var/named/

[root@ns1 named]# vim lan.bt.com.zone

$TTL 1D

@       IN SOA  bt.com.   admin.bt.com. (

                                        0       ; serial

                                        1D      ; refresh

                                        1H      ; retry

                                        1W      ; expire

                                        3H )    ; minimum

@    IN  NS  ns1.bt.com.

ns1  IN  A   192.168.10.101

www  IN  A   192.168.10.102

mail IN  A   192.168.10.103

ftp  IN  A   192.168.10.104

（2）外部区域文件

[root@ns1 named]# vim wan.bt.com.zone

$TTL 1D

@       IN SOA  bt.com.  admin.bt.com. (

                                        0       ; serial

                                        1D      ; refresh

                                        1H      ; retry

                                        1W      ; expire

                                        3H )    ; minimum

@    IN NS  ns1.bt.com.

ns1  IN A   173.16.16.101

www  IN A   173.16.16.102

mail IN A   173.16.16.103

ftp  IN A   173.16.16.104

[root@ns1 named]# chown named lan.bt.com.zone wan.bt.com.zone

3：语法检测
[root@ns1 named]# named-checkconf -z /etc/named.conf

zone bt.com/IN: loaded serial 0

zone bt.com/IN: loaded serial 0

[root@ns1 named]# named-checkzone bt.com /var/named/lan.bt.com.zone

zone bt.com/IN: loaded serial 0

OK

[root@ns1 named]# named-checkzone bt.com /var/named/wan.bt.com.zone

zone bt.com/IN: loaded serial 0

OK

4：启动服务

[root@ns1 named]# systemctl start named

4：客户端验证

1：外网客户端

[root@localhost ~]# yum -y install bind-utils

[root@localhost ~]# nslookup www.bt.com

Server: 173.16.16.1

Address: 173.16.16.1#53

Name: www.bt.com

Address: 173.16.16.101

2：内网客户端

[root@localhost ~]# yum -y install bind-utils

[root@localhost ~]# nslookup www.bt.com

Server: 192.168.1.1

Address: 192.168.1.1#53

Name: www.bt.com

Address: 192.168.1.5

二：多域名解析

[root@ns1 named]# vim /etc/named.conf

view "LAN" {

        match-clients { 192.168.10.0/24;};

        zone "bt.com" IN {

        type master;

        file "lan.bt.com.zone";

        };

        zone "benet.com" IN {

        type master;

        file "lan2.bt.com.zone";

        };

};

[root@ns1 named]# vim lan2.bt.com.zone

$TTL 1D

@       IN SOA  bt.com.   admin.bt.com. (

                                        0       ; serial

                                        1D      ; refresh

                                        1H      ; retry

                                        1W      ; expire

                                        3H )    ; minimum

@    IN  NS  ns1.bt.com.

ns1  IN  A   192.168.10.101

www  IN  A   191.168.10.102

mail IN  A   191.168.10.103

ftp  IN  A   191.168.10.104

[root@ns1 named]# chown named lan2.bt.com.zone

[root@ns1 named]# systemctl restart named

备注：有几个域名，就添加多少个zone，每个zone对应一个区域文件

客户端测试

[root@client ~]# nslookup ftp.benet.com

Server: 192.168.10.101

Address: 192.168.10.101#53

Name: ftp.benet.com

Address: 191.168.10.104

三：子域

实验环境：

父域服务器：192.168.10.101

子域服务器：192.168.10.102

一：主服务器的配置

1：安装bind

[root@localhost ~]# setenforce 0

[root@localhost ~]# systemctl stop firewalld

[root@localhost ~]# yum -y install bind

2：设置named主配置文件

[root@localhost ~]# vim /etc/named.conf

options {

        listen-on port 53 { 192.168.10.101; };

        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";

        recursing-file  "/var/named/data/named.recursing";

        secroots-file   "/var/named/data/named.secroots";

        allow-query     { any; };

}；

3：创建主DNS服务器

[root@localhost ~]# vim /etc/named.rfc1912.zones

在末尾添加：

zone "accp.com" IN {

        type master;

        file "accp.com.zone";

};

4：创建正向区域文件

[root@localhost ~]# vim /var/named/accp.com.zone

$TTL 1D

@       IN SOA  accp.com.   admin.accp.com. (

                                        0       ; serial

                                        1D      ; refresh

                                        1H      ; retry

                                        1W      ; expire

                                        3H )    ; minimum

@    IN  NS  ns1.accp.com.

ns1  IN  A   192.168.10.101

ns2  IN  A   192.168.10.102

www  IN  A   192.168.10.103

ftp  IN  A   192.168.10.104

[root@localhost ~]# chown :named /var/named/accp.com.zone

二：子域服务器设置

1：安装bind服务

[root@localhost ~]# setenforce 0

[root@localhost ~]# systemctl stop firewalld

[root@localhost ~]# yum -y install bind

2：配置主配置文件

[root@localhost ~]# vim /etc/named.conf

options {

        listen-on port 53 { 192.168.10.102; };

        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";

        recursing-file  "/var/named/data/named.recursing";

        secroots-file   "/var/named/data/named.secroots";

        allow-query     { any; };

        dnssec-enable no;

        dnssec-validation no;

备注：

dnssec-enable no;   dnssec功能会对解析结果进行验证

dnssec-validation no;  是否为权威解答，不是就会报错

建议关闭，否则会影响委派转发

3：设置区域文件

[root@localhost ~]# vim /etc/named.rfc1912.zones

在末尾添加：

zone "zz.accp.com" IN {

        type master;

        file "zz.accp.com.zone";

};

zone "accp.com" IN {

        type forward;

        forwarders { 192.168.10.101; };

};

备注：

forwarders { 192.168.10.101; };    转发器，本机无法解析的条目转发至10.101为其解析

[root@localhost ~]# vim /var/named/zz.accp.com.zone

$TTL 1D

@       IN SOA  zz.accp.com.   admin.zz.accp.com. (

                                        0       ; serial

                                        1D      ; refresh

                                        1H      ; retry

                                        1W      ; expire

                                        3H )    ; minimum

@    IN  NS  ns2.zz.accp.com.

ns1  IN  A   192.168.10.101

ns2  IN  A   192.168.10.102

mail IN  A   192.168.100.103

ftp  IN  A   192.168.100.104

[root@localhost ~]# chown :named /var/named/zz.accp.com.zone
