DNS服务器题目

DNS服务器题目

搭建主DNS服务器，要求如下：该DNS服务器能解析www.qq.com和www.163.com的IP地址。

步骤

1.配置文件
[root@localhost /]# vim /etc/named.conf 
options  {                                
        listen-on port 53 {192.168.182.133 ; };
        directory  "/var/named";
};

zone "qq.com" IN{
        type master;
        file "named.qq.com";
};

zone "163.com" IN{
        type master;
        file "named.163.com";
};


[root@localhost named]# vim named.qq.com

$TTL 1D
@	IN SOA	 master.qq.com. admin.qq.com. (
					0	; serial
					1D	; refresh
					1H	; retry
					1W	; expire
					3H )	; minimum
	NS	master.qq.com.
master	A	192.168.182.133
mail    A    192.168.74.30
www     A    192.168.74.20


[root@localhost named]# vim named.163.com

$TTL 1D
@	IN SOA	master.163.com.  admin.163.com. (
					0	; serial
					1D	; refresh
					1H	; retry
					1W	; expire
					3H )	; minimum
	NS	master.163.com.
master  A       192.168.182.133
mail	A	192.168.182.30
www     A       192.168.182.20

2.修改DNS
[root@localhost named]# vim /etc/resolv.conf 
# Generated by NetworkManager
nameserver 192.168.182.133

3.重启服务
[root@localhost named]# systemctl restart named

4.测试
[root@localhost named]# nslookup www.qq.com
Server:		192.168.182.133
Address:	192.168.182.133#53

Name:	www.qq.com
Address: 192.168.74.20

[root@localhost named]# nslookup www.163.com
Server:		192.168.182.133
Address:	192.168.182.133#53

Name:	www.163.com
Address: 192.168.182.20
