Registration of a domain name for the web server of the SAYMON server

Before installation and configuration of an SSL certificate, a domain name (for example, example.com) should be registered. You can register a domain name with the primary and/or secondary DNS hosting. For this, you can contact any domain name registrar.

If you choose only the secondary DNS hosting, you will need to configure a primary DNS server locally.

Before you register a domain name, it is necessary to obtain a fixed IP address from the provider.

Configuration of primary DNS server

Configure the following records:

  • the A record, where example.com points to your server’s public IP address;

  • the A record, where www.example.com points to your server’s public IP address.

You need to create a server block for a domain (for example, /etc/nginx/sites-available/example.com).

You also need to open port 80 for HTTP and port 443 for HTTPS.

Example of how to open ports in ufw:

$ sudo ufw allow 80

$ sudo ufw allow 443
