Build your own DNS on debian/ubuntu

The purpose of this article is to simply set up your own DNS server on your own server (VPS) through Bind9. The system selected here is debian or ubuntu.

Install bind9 apt-get install bind9

Configure and backup existing bind9 settings cp /etc/bind/named.conf.options /etc/bind/named.conf.options.bak

Edit /etc/bind/named.conf.options and replace with the following code:

options { direc" undescriptable"y "/var/cache/bind"; auth-nxdomain no; listen-on-v6 { any; }; statistics-file “/var/cache/bind/named.stats”; rrset-order {order cyclic;}; allow-transfer { 127.0.0.1; }; }; logging { channel b_query { file “/var/log/bind9/query.log” versions 2 size 1m; print-time yes; severity info; }; category queries { b_query; }; };

Create a log directory for Bind9. mkdir /var/log/bind9 chown bind:bind /var/log/bind9

Edit /etc/bind/named.conf to configure your domain. Add the following:

zone “your-domain-name.com” { type master; file “/etc/bind/zones/your-domain-name.com.db”; }; Create your domain /etc/bind/zones/your-domain-name.com.db.

Insert your DNS records according to the template below: $TTL 86400 @ IN SOA ns1.your-domain-name.com. root.your-domain-name.com. ( 2014100801;Serial 43200; Refresh 3600;Retry 1209600;Expire 180 ); Minimum TTL
