1. Reverse Proxy Snippet
Route incoming port 80 traffic to a local app running on port 3000:
nginx server { listen 80; server_name yourdomain.com; location / { proxy_pass [http://127.0.0.1:3000](http://127.0.0.1:3000); proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } 2. Load Balancer Snippet Distribute requests across multiple upstream backend nodes using Round-Robin:upstream backend_servers { server 10.0.0.1:8080; server 10.0.0.2:8080; } server { listen 80; server_name loadbalancer.yourdomain.com; location / { proxy_pass http://backend_servers; } } 📖 Want the complete step-by-step setup guide including SSL configuration with Let's Encrypt? 👉 Read the Full Step-by-Step Guide on My Blog
