DNS preparation

Prepare two DNS records before installation when possible: one for the control panel and one for the public site.

Example DNS 
panel.example.com    A    SERVER_PUBLIC_IP
example.com          A    SERVER_PUBLIC_IP

When DNS already resolves to the new server, the installer can attempt Let's Encrypt certificate provisioning automatically.

Deployment flow

E4S installation flow
  1. Prepare Linux. Start from a clean supported operating system.
  2. Prepare DNS. Point the panel and public-site records to the server.
  3. Run Quick Install. Download the bootstrap script and execute it.
  4. Answer installer prompts. Panel domain, site domain and owner identity.
  5. Install platform. Runtime, PostgreSQL, Redis, Nginx and E4S services are prepared.
  6. Activate entitlement. Commercial license or automatic trial.
  7. Open panel. Use the generated credentials file.
