What is a Name server and how it works? How connect VPS to Domain?

Hi!

A domain’s nameservers are what provide the mapping from the domain name to an actual IP address, so that browsers and other clients know what server they should connect to. Since your domain’s nameservers are ns1-3.digitalocean.com, you will need to add any DNS records using DigitalOcean’s control panel.

According to a member of the VestaCP Team, it is not possible to host the control panel on port 80 or 443 (HTTPS). However, you can still add an A record called panel and point it to your Droplet. Once you’ve done that, you will be able to access the control panel by browsing to http://panel.yourdomain.com:PORT.

Theoretically, though, it is possible to configure Apache to proxy panel.yourdomain.com:PORT to 127.0.0.1:PORT by adding a virtualhost that looks like this:

<VirtualHost *:80>
    ProxyPreserveHost On
    ServerName panel.yourdomain.com

    ProxyPass / http://127.0.0.1:PORT/
    ProxyPassReverse / http://127.0.0.1:PORT/
</VirtualHost>

I have never used VestaCP myself before, so I do not know if that will break anything, but you can always give it a shot and just delete it if it doesn’t work. Good luck!
