Web server

Domain configuration

DNS records, domain aliases and reverse proxy architecture (frontend Nginx → backend port).

  1. DNS A record

    At your domain registrar set A record (and AAAA for IPv6) to the server public IP. Verify:

    dig +short example.com A
dig +short www.example.com A

  2. Domain aliases

    Add extra domains (e.g. www) in Project settings. The panel includes them in the virtual host when created.

  3. Reverse proxy architecture

    If reverse proxy is enabled, frontend Nginx listens on 80/443 and forwards traffic to the project internal backend port (Apache or Nginx). Overview is in the Proxy tab.

  4. Global reverse proxy

    Reverse proxy module in the sidebar is for global frontend Nginx configuration and port management.

    Tip

    Ports 80 and 443 must be open in UFW before public access and SSL issuance.
