子域

子域同父域在同一个服务器上

新建子域jevon.danran.com

1. vim /etc/named.rfc1912.zones

   zone "jevon.danran.com" IN {
   
   type master;
   
   file "jevon.danran.zone";
   
   allow-update { none; };
   
   };

2. 编辑jevon.danran.com域的数据库文件

   1. 编辑正向解析文件
      
      cp -p /var/named/danran.zone /var/named/jevon.danran.zone \带权限复制数据库文件
      
      vim /var/named/jevon.danran.zone
      
      $TTL 1D
      
      @ IN SOA ns1.jevon.danaran.com. dnsadmin.jevon.danran.com. (
      
      0 ; serial
      
      1D ; refresh
      
      1H ; retry
      
      1W ; expire
      
      3H ) ; minimum
      
      NS ns1.jevon.danran.com.
      
      NS ns2

       ns1     A       192.168.198.134
      
       ns2     A       192.168.198.11
      
       websrv  A       192.168.198.51
      
       ftpsrv  A       192.168.198.52
      
       www     CNAME   websrv
      

   2. 编辑反向解析文件
      
      cp -p /var/named/IP.danran.zone /var/named/IP.jevon.danran.zone
      
      vim /var/named/IP.jevon.danran.zone
      
      $TTL 1D
      
      @ IN SOA ns1.jevon.danran.com. admin.jevon.danran.com. (
      
      0 ; serial
      
      1D ; refresh
      
      1H ; retry
      
      1W ; expire
      
      3H ) ; minimum
      
      NS @

               A       192.168.198.134
      
       134     PTR     ns1.jevon.danran.com.
      
       131     PTR     ns2.jevon.danran.com.

       52      PTR     ftpsrv.jevon.danran.com.
      

3. 加载配置文件
   
   rndc reload

4. 访问测试
   
   dig www.jevon.danran.com @192.168.198.134

子域同父域不在同一台服务器上

新建子域zijie.danran.com
