实验设备

  主服务器:OpenElur Linux  IP地址为192.168.188.129

  从服务器:RedHat Linux  IP地址为192.168.188.128

实验步骤

1.进行主服务器的基础配置

#安装DNS对应工具
[root@OpenElurRJW ~]# yum install bind -y
#编辑DNS系统配置信息
[root@OpenElurRJW ~]# cat /etc/named.conf
options {
        listen-on port 53 { 192.168.188.129; };
        directory       "/var/named";
        allow-query     {any;};
        allow-transfer  {192.168.188.128; };
};
zone "RRR.com" IN {
        type master;
        file "RRR";
};
zone "188.168.192.in-addr.arpa" IN {
        type master;
        file "192";
};

 2.配置主服务器的解析配置文件

#编辑正向解析配置文件
[root@OpenElurRJW ~]# cat /var/named/RRR
$TTL 1D
@       IN SOA @ admin.RRR.com. ( 2024011700 1D 1H 3H 1D)
        IN NS  dns.RRR.com.
dns     IN A 192.168.188.129
www     IN A 192.168.188.129
ftp     IN A 192.168.188.129
a       IN A 192.168.188.129
aaa     IN CNAME        a
#编辑反向解析配置文件
[root@OpenElurRJW ~]# cat /var/named/192
$TTL 1D
@       IN SOA @        admin.RRR.com. ( 2024011701 1D 1H 3H 1D )
        IN NS           dns.RRR.com.
129     IN PTR          dns.RRR.com.
129     IN PTR          www.RRR.com.
#重启服务
[root@localhost ~]# systemct restart named

3.进行从服务器的基础配置 

#安装DNS对应工具
[root@RedHatRJW ~]# yum install bind -y
#编辑DNS系统配置文件
[root@RedHatRJW ~]# cat /etc/named.conf
options {
        listen-on port 53 { 192.168.188.129; };
        directory       "/var/named";
};
zone "RRR.com" IN {
        type slave;
        file "slaves/named.RRR.com";
        masters { 192.168.188.129 ; };
};
zone "188.168.129.in-addr.arpa" IN {
        type slave;
        file "slaves/named.192.coom";
        masters { 192.168.188.129 ;};
};
#重启服务
[root@localhost ~]# systemct restart named

 4.实验结果检验

[root@RedHatRJW ~]# nslookup
> server 192.168.188.129
Default server: 192.168.188.129
Address: 192.168.188.129#53
> 192.168.188.129
129.188.168.192.in-addr.arpa    name = dns.RRR.com.
129.188.168.192.in-addr.arpa    name = www.RRR.com.
> www.RRR.com
Server:         192.168.188.129
Address:        192.168.188.129#53
Name:   www.RRR.com
Address: 192.168.188.129
