1、准备

例：两台192.168.219.146(主), 192.168.219.147(从), 域名www.panyangduola.com

主、从DNS服务器均需要安装bind、bind-chroot、bind-utils

yum -y install bind bind-utils bind-chroot

如果防火墙开启，配置防火墙，添加服务(防火墙已禁用则忽略)

firewall-cmd --permanent --add-service=dns
firewall-cmd --reload

2、主DNS服务器(192.168.219.146)配置

编辑配置文件

vim /etc/named.conf

找到其中两行

1. listen-on port 53 { 127.0.0.1; };

2. allow-query { localhost; };

   修改为

3. listen-on port 53 { any; };

4. allow-query { any; };

2-1、配置正向解析

编辑文件/etc/named.rfc1912.zones，在末尾添加需要解析的域

vim /etc/named.rfc1912.zones

zone "panyangduola.com" IN {
      type master;
      file "data/panyangduola.com.zone";
};

创建panyangduola.com.zone解析域

vim /var/named/data/panyangduola.com.zone

$TTL 3600
$ORIGIN panyangduola.com.
@       IN      SOA   panyangduola.com. admin.panyangduola.com. (
        2018042101
        1D
        1H
        1W
        3H
)
@       IN      NS      ns1.panyangduola.com.
@       IN      NS      ns2.panyangduola.com.
ns1     IN      A       192.168.219.146
ns2     IN      A       192.168.219.147
www     IN      A       192.168.219.146
web     IN      CNAME   www

2-2、配置反向解析

编辑文件/etc/named.rfc1912.zones，在末尾添加需要解析的域

vim /etc/named.rfc1912.zones

zone "219.168.192.in-addr.arpa" IN {
          type master;
          file "data/219.168.192.zone"; 
};

创建219.168.192.zone解析域

vim /var/named/data/219.168.192.zone

$TTL 3600
$ORIGIN  219.168.192.in-addr.arpa.
@       IN      SOA  panyangduola.com. admin.panyangduola.com. (
        2018042101
        1D
        1H
        1W
        3H
)
@       IN      NS      ns1.panyangduola.com.
@       IN      NS      ns2.panyangduola.com.
146      IN      PTR     ns1.panyangduola.com.
147      IN      PTR     ns2.panyangduola.com.
146      IN      PTR     www.panyangduola.com.

2-3、对DNS配置文件进行一下语法检查：

cd /etc
named-checkconf named.conf
named-checkconf named.rfc1912.zones
cd /var/named/data
named-checkzone panyangduola.com panyangduola.com.zone
named-checkzone 219.168.192.in-addr.arpa 219.168.192.zone

2-4、编辑/etc/resolv.conf，添加

vim /etc/resolv.conf

search localdomain
nameserver 192.168.219.146

2-5、如果2-3步骤没有错误发生的话，启动named服务

重启named

systemctl restart named

查看状态

systemctl status named

2-6、检查主DNS服务器解析是否成功

ping命令验证

ping -c 4 www.panyangduola.com

nslookup命令验证

nslookup
>www.panyangduola.com

nslookup
>192.168.219.146

3、从DNS服务器(192.168.219.147)配置

编辑named.conf文件

vim /etc/named.conf

找到其中两行　　

1. listen-on port 53 { 127.0.0.1; }; 　　
2. allow-query { localhost; };

修改为

1. listen-on port 53 { any; };
2. allow-query { any; };

3-1、修改主DNS服务器(192.168.219.146)的配置/etc/named.rfc1912.zones

vim /etc/named.rfc1912.zones

zone "panyangduola.com" IN {
      type master;
      file "data/panyangduola.com.zone";
      allow-transfer {192.168.219.147;};
      notify yes;
      also-notify {192.168.219.147;};
};
zone "219.168.192.in-addr.arpa" IN {
      type master;
      file "data/219.168.192.zone";
      allow-transfer {192.168.219.147;}; 
      notify yes;   
      also-notify {192.168.219.147;};  
};

3-2、配置从DNS服务器(192.168.219.147)正向解析

编辑文件/etc/named.rfc1912.zones，在末尾添加需要解析的域

vim /etc/named.rfc1912.zones

zone "panyangduola.com" IN {
　　type slave;
　　file "data/panyangduola.com.zone";
　　masters { 192.168.219.146; };
};

创建panyangduola.com.zone空文件

touch /var/named/data/panyangduola.com.zone 

设置所有者　　

cd /var/named/data
chown named:named panyangduola.com.zone

3-3、配置从DNS服务器(192.168.219.147)反向解析

在文件/etc/named.rfc1912.zones中添加

vim etc/named.rfc1912.zones

zone "219.168.192.in-addr.arpa" IN {
    type slave;
    file "data/219.168.192.zone";
    masters { 192.168.219.146; };　　　
};

创建空文件219.168.192.zone

touch /var/named/data/219.168.192.zone

设置所有者

cd /var/named/data
chown named:named 219.168.192.zone

3-4、对DNS配置文件进行一下语法检查：

cd /etc
named-checkconf named.conf
named-checkconf named.rfc1912.zones

3-5、编辑/etc/resolv.conf，添加

vim /etc/resolv.conf

search localdomain
nameserver 192.168.219.147

3-6、如果3-4步骤没有错误发生的话，启动named服务

重启named

systemctl restart named

查看状态

systemctl status named

3-7、查看文件/var/named/data/panyangduola.com.zone和/var/named/data/219.168.192.zone是否有二进制数据

cat /var/named/data/panyangduola.com.zone
cat /var/named/data/219.168.192.zone

3-8、检查从DNS服务器解析是否成功

ping命令验证

ping -c 4 www.panyangduola.com

nslookup命令验证

nslookup
>192.168.219.147
