1，主服务器的配置

• 关闭防火墙和Linux的安全程序

[root@localhost ~]# systemctl stop firewalld.service #关闭防火墙
[root@localhost ~]# setenforce 0 #关闭安全策略

• 下载DNS

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

• 配置操作

[root@localhost ~]# vim /etc/named.confoptions{listen-on port 53 { 192.168.85.136; };directory "/var/named";allow-query { any; };allow-transfer { 192.168.85.135; };
};zone "openlab.com" IN {type master;file "named.openlab.com";
};zone "85.168.192.in-addr.arpa" IN {type master;file "named.192";allow-update { none; };
};

2，从服务器的配置 

• 关闭防火墙和Linux的安全程序

[root@localhost ~]# systemctl stop firewalld.service #关闭防火墙
[root@localhost ~]# setenforce 0 #关闭安全策略

• 下载DNS

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

• 配置操作

options{listen-on port 53 { 192.168.85.135; };directory "/var/named/slaves";allow-query { any; };
};zone "openlab.com" IN {type slave;file "named.openlab.com";masters { 192.168.85.136; };
};zone "85.168.192.in-addr.arpa" IN {type slave;file "named.192";masters { 192.168.85.136; };
};

3，完全区域传送

• 主服务器：

[root@localhost ~]# vim /var/named/named.openlab.com$TTL 1D
@       IN      SOA     @       lxx.qq.com. ( 20241101001D1H5H1D
)IN      NS      ns.openlab.com.
ns      IN      A       192.168.85.136www     IN      A       172.25.250.111
ftp     IN      A       172.25.250.100
mail    IN      A       172.25.250.132
wwww    IN      CNAME   www[root@localhost ~]# systemctl restart named

 

• 从服务器：

[root@localhost ~]# systemctl restart named[root@localhost ~]# ll /var/named/slaves
total 16
-rw-r--r--. 1 named named  821 Nov  1 22:16 managed-keys.bind
-rw-r--r--. 1 named named 3733 Nov  1 22:16 managed-keys.bind.jnl

-rw-r--r--. 1 named named  384 Nov  1 21:52 named.openlab.com

4，增量区域传送

• 主服务器：

[root@localhost ~]# vim /var/named/named.openlab.com$TTL 1D
@       IN      SOA     @       lxx.qq.com. ( 20241101011M1M1M1M
