Simple Load Balancing

An example NGINX configuration that performs simple load balancing across multiple backend servers.

nginx.conf

http {
  upstream myproject {
    server 127.0.0.1:8000 weight=3;
    server 127.0.0.1:8001;
    server 127.0.0.1:8002;    
    server 127.0.0.1:8003;
  }

  server {
    listen 80;
    server_name www.domain.com;
    location / {
      proxy_pass http://myproject;
    }
  }
}

Key points

• The upstream block defines a group of backend servers.
• The weight parameter controls load distribution (higher weight = more requests).
• By default, NGINX uses round-robin load balancing.
• Other load balancing methods include least_conn, ip_hash, and hash.
