bind9

This repo details the configuration for BIND DNS on Ubuntu 22.04. You can set up your own DNS server by following this guide.

The basic configuration is as below:

1. Install bind9 and check its status

apt update -y && apt upgrade -y
apt install bind9 bind9utils bind9-doc -y
sudo systemctl status bind9

2. Edit /etc/bind/named.conf.options and check its syntax with named-checkconf /etc/bind/named.conf.options. There should be no output.

3. Edit /etc/bind/named.conf.local and check its syntax with named-checkconf /etc/bind/named.conf.local. There should be no output.

4. Create a directory for your zone files with mkdir /etc/bind/zones and create your zone file in it as /etc/bind/zones/example.com. Replace example.com with your domain name.

5. Check its syntax with named-checkzone example.com /etc/bind/zones/example.com.

6. Restart bind9 with sudo systemctl restart bind9.
