Nginx Server Configuration: Proxy Pass, URL Rewrites, SSL, and Error Pages

The guide explains how to configure an Nginx server to listen on port 80, serve static files, and proxy requests to different backend APIs. It also shows how to define custom error pages and enable HTTPS with SSL certificates.

server { listen 80; root /data/php/; server_name api.open.com; # URL rewrite for test1api location ^~ /test1api/ { proxy_set_header Host test1api.open.com; proxy_set_header X-forwarded-for $proxy_add_x_forwarded_for; proxy_set_header X-real-ip $remote_addr; proxy_pass http://test1api.open.com/; } # URL rewrite for test2api location ^~ /test2api/ { proxy_set_header Host test2api.open.com; proxy_set_header X-forwarded-for $proxy_add_x_forwarded_for; proxy_set_header X-real-ip $remote_addr; proxy_pass http://test2api.open.com/; } # Custom error pages error_page 404 /404.html; location = /404.html { root /usr/share/nginx/html; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } }

For HTTPS, the configuration adds SSL settings and points to the certificate and key files.

server { listen 443; root /data/php/; server_name api.open.com; ssl on; ssl_certificate /usr/local/ssl/1_api.open.com_bundle.crt; ssl_certificate_key /usr/local/ssl/1_api.open.com.key; }

Repeated sections illustrate how the same URL rewrite blocks can be placed in both HTTP and HTTPS server blocks. The article ends with a decorative line and a list of recommended reading links.
