主DNS服务器配置

1. 主DNS服务器使用Redhat7.5，域名为juzldream.fun,且搭配的IP网段为192.168.5.0/24这一段，因此主要的正解网域为juzldream.fun，而反解的网域则为192.168.5.0/24。

2. 配置/etc/named/named.conf options选项配置

   options {
           directory       "/var/named";
           allow-recursion {192.168.5.136;};
           notify yes;         #启动通知功能
   };
   
   zone "." IN {
           type hint;
           file "named.ca";
   };
   
   zone "localhost" IN {
           type master;
           file "named.localhost";
           allow-transfer {none;};  #不允许增量传送
   };
   
   zone "0.0.127.in-addr.arpa" IN {
           type master;
           file "named.loopback";
           allow-transfer {none;};
   };
   
   zone "juzldream.fun" IN {
           type master;
           file "juzldream.fun";
           allow-transfer {192.168.5.128;};     #允许192.168.5.128从服务器传送
   }; 
   
   zone "5.168.192.in-addr.arpa" IN {
       type master;
       file "juzldream.back";
       allow-transfer {192.168.5.128;};
   };
   

3. juzldream.fun 正向区域数据文件配置

   $TTL 600
   @       IN      SOA     ns1.juzldream.fun. admin.juzldream.fun. (
                                              2019021805
                                              1H
                                              5M
                                              2D
                                              6H
   )
           IN      NS      ns1
           IN      NS      ns2
           IN      MX  10  mail
   ns1     IN      A       192.168.5.130
   ns2     IN      A       192.168.5.128  ;从DNS服务地址,tips 从服务器需要配置ns2地址。
   mail    IN      A       192.168.5.140
   www     IN      A       192.168.5.150
   www     IN      A       192.168.5.151
   ftp     IN      A       192.168.5.160
   pop     IN      CNAME   mail
   web     IN      CNAME   www
   test    IN      A       192.168.5.170
   *.juzldream.fun. IN     A       192.168.5.88 ;DNS泛域名解析
   

4. juzldream.jun 反向区域数据文件配置

   $TTL 600
   @       IN      SOA     ns1.juzldream.fun. admin.juzldream.fun. (
                                               2019021803
                                               1H
                                               5M
                                               2D
                                               6H
   )
           IN      NS      ns1.juzldream.fun.
           IN      NS      ns2.juzldream.fun.
   130     IN      PTR     ns1.juzldream.fun.
   128     IN      PTR     ns2.juzldream.fun.
   140     IN      PTR     mail.juzldream.fun.
   150     IN      PTR     www.juzldream.fun.
   151     IN      PTR     www.juzldream.fun.
   160     IN      PTR     ftp.juzldream.fun.
   170     IN      PTR     test.juzldream.fun.
   

5. 检查配置文件设置是否正确

   [root@testdns ~]# named-checkconf

6. 检查zone文件配置是否正确

   [root@testdns ~]# named-checkzone "5.168.192.in-addr.arpa" /var/named/juzldream.back 
   zone 5.168.192.in-addr.arpa/IN: loaded serial 2019021804
   OK
   [root@testdns ~]# named-checkzone "juzldream.fun" /var/named/juzldream.fun
   zone juzldream.fun/IN: loaded serial 2019021806
   OK
   
   

7. 启动DNS服务器

   named -f -g -d 3 -u named

8. 域名正反向测试
