About this tool

Create the Nginx server block without starting from scratch.

In Nginx, each site is configured by a server block that defines which port to listen on, which domain it serves, where the files are and how to handle SSL, caching and security. Building this by hand requires remembering the exact syntax of several directives. This generator creates a commented server block from a few choices: the application type (static site, SPA with try_files to index.html, reverse proxy to an upstream like Node or an app on port 3000, or PHP with FastCGI), the domain, the root directory, and options for HTTPS with a certificate, automatic HTTP-to-HTTPS redirect, HTTP/2, Gzip compression, one-year static asset caching and security headers. When HTTPS is enabled, the tool also generates the block that redirects port 80 to 443. Copy the result to a file in /etc/nginx/sites-available and enable it with a symlink in sites-enabled. Everything is generated locally.

How to use

Generate the server block in three steps.

Choose the application type and provide the domain and directory (or the proxy upstream).
Enable HTTPS, HTTP/2, Gzip, caching and security as needed, and adjust the certificate paths.
Copy the config to /etc/nginx/sites-available and reload Nginx with nginx -t && systemctl reload nginx.

FAQ

Frequently asked questions

Where do I put this configuration on the server?

The standard is to save it in /etc/nginx/sites-available/your-domain and create a symlink in /etc/nginx/sites-enabled. Then run nginx -t to validate the syntax and systemctl reload nginx (or service nginx reload) to apply without dropping connections.

What's the difference between the application types?

Do I need an SSL certificate to use HTTPS?

Is the HTTP-to-HTTPS redirect safe?

What is proxy_pass for?

How do I test that the configuration is correct?
