CWP DNS Part 2 : How to Configure DNS properly for CentOS WebPanel on CentOS 7.6

7.Open Main Configuration file

 # vi /etc/named.conf

     12 options {
     13         listen-on port 53 { any; };
     14         listen-on-v6 port 53 { ::1; };
     15         directory       "/var/named";
     16         dump-file       "/var/named/data/cache_dump.db";
     17         statistics-file "/var/named/data/named_stats.txt";
     18         memstatistics-file "/var/named/data/named_mem_stats.txt";
     19         recursing-file  "/var/named/data/named.recursing";
     20         secroots-file   "/var/named/data/named.secroots";
     21         allow-query     { any; };


     33         recursion no;
     34
     35         dnssec-enable yes;
     36         dnssec-validation yes;

     54 zone "." IN {
     55         type hint;
     56         file "named.ca";
     57 };
     58
     59 include "/etc/named.rfc1912.zones";
     60 include "/etc/named.root.key";
     61
     62
     63 zone "ns1.datahead.biz" {type master;file "/var/named/ns1.datahead.biz.db";};
     64 zone "ns2.datahead.biz" {type master;file "/var/named/ns2.datahead.biz.db";};
     65
     66 // zone datahead.biz
     67 zone "datahead.biz" {type master; file "/var/named/datahead.biz.db";};
     68 // zone_end datahead.biz
     69 

8.Open Zone file and Create A Record if missing

 # vi /var/named/ns1.datahead.biz.db

; Panel %version%
; Zone file for ns1.datahead.biz
$TTL 14400
ns1.datahead.biz.      86400      IN      SOA      ns1.datahead.biz.      info.datahead.biz.      (
                                2013071600 ;serial, todays date+todays
                                86400 ;refresh, seconds
                                7200 ;retry, seconds
                                3600000 ;expire, seconds
                                86400 ;minimum, seconds
      )
ns1.datahead.biz. 86400 IN NS ns1.datahead.biz.
ns1.datahead.biz. 86400 IN NS ns2.datahead.biz.
ns1.datahead.biz. 14400 IN A 192.120.10.3

 # vi /var/named/ns2.datahead.biz.db

; Panel %version%
; Zone file for ns2.datahead.biz
$TTL 14400
ns2.datahead.biz.      86400      IN      SOA      ns1.datahead.biz.      info.datahead.biz.      (
                                2013071600 ;serial, todays date+todays
                                86400 ;refresh, seconds
                                7200 ;retry, seconds
                                3600000 ;expire, seconds
                                86400 ;minimum, seconds
      )
ns2.datahead.biz. 86400 IN NS ns1.datahead.biz.
ns2.datahead.biz. 86400 IN NS ns2.datahead.biz.
ns2.datahead.biz. 14400 IN A 192.120.10.3

9. Now open the master file and Create the below records with your own IP

 # vi /var/named/datahead.biz.db

; Generated by CWP
; Zone file for datahead.biz
$TTL 14400
@    86400        IN      SOA     ns1.datahead.biz. admin.datahead.biz. (
                                2019012401      ; serial, todays date+todays
                                3600            ; refresh, seconds
                                7200            ; retry, seconds
                                1209600         ; expire, seconds
                                86400 )         ; minimum, seconds

10.Now check the configuration file and Restart the DNS Server

# named-checkconf /etc/named.conf
# named-checkzone datahead.biz /var/named/datahead.biz.db
zone datahead.biz/IN: loaded serial 2019012401
OK

# systemctl restart named
