Binding a Single Domain to a VPS Server on NodeJS

Let's try the simplest way to bind a domain to a server. This method will work if you will have only one domain on your server.

For this method, you need to run the test site script on port 80:

app.jsapp.listen(80, function() {
  console.log('running');
});

The site running on this port will be accessible only by IP address, without specifying a port:

urlhttp://12.345.678.90

Next, you need to have a domain or subdomain purchased from a registrar. In the domain registrar's panel, go to the Domains section, look for Zone Management there, and there find our domain (or subdomain) and change its A-record to the IP of our server.

Wait a few minutes (no more than 10) and then try to visit the domain name. If everything is done correctly, we should see the result of the test script's work.
