CentOS7 - não é possível iniciar o BIND

Question

Eu tentei várias vezes, mas ainda não consigo iniciar o BIND depois de adicionar minha primeira zona.

1. Meu /etc/named.conf se parece com:

   options {
   listen-on port 53 { any; };
   listen-on-v6 port 53 { ::1; };
   directory   "/var/named";
   dump-file   "/var/named/data/cache_dump.db";
   statistics-file "/var/named/data/named_stats.txt";
   memstatistics-file "/var/named/data/named_mem_stats.txt";
   allow-query     { localhost;172.19.0.0/24; };
   
   recursion no;
   
   dnssec-enable yes;
   dnssec-validation yes;
   
   /* Path to ISC DLV key */
   bindkeys-file "/etc/named.iscdlv.key";
   
   managed-keys-directory "/var/named/dynamic";
   
   pid-file "/run/named/named.pid";
   session-keyfile "/run/named/session.key";
   };
   
   logging {
       channel default_debug {
               file "data/named.run";
               severity dynamic;
           };
   };
   
   zone "." IN {
       type hint;
       file "named.ca";
   };
   
   zone "netlabbuilder.net" IN {
       type master;
       file "netlabbuilder.net.zone";
       allow-update { none; };
   };
   
   include "/etc/named.rfc1912.zones";
   include "/etc/named.root.key";
   

   "systemctl status named" mostra o erro " fim inesperado de entrada " na zona do netlabbuilder.net.

2. Quando eu removo a seção da zona "netlabbuilder.net", ela funciona bem:

   ● named.service - Berkeley Internet Name Domain (DNS)
   Loaded: loaded (/usr/lib/systemd/system/named.service; enabled; vendor preset: disabled)
   Active: active (running) since Wed 2017-08-09 15:50:50 CEST; 7s ago
   Main PID: 15763 (named)
   CGroup: /system.slice/named.service
          └─15763 /usr/sbin/named -u named
   

3. O netlabbuilder.net.zone definido em / var / named /
