Overview

Master Nginx configuration for production-grade web servers, reverse proxies, load balancing, SSL termination, caching, and API gateway patterns with advanced performance tuning.

When to Use

• Reverse proxy setup
• Load balancing between backend services
• SSL/TLS termination
• HTTP/2 and gRPC support
• Caching and compression
• Rate limiting and DDoS protection
• URL rewriting and routing
• API gateway functionality

Quick Start

Minimal working example:

# /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
worker_rlimit_nofile 65535;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
    worker_connections 4096;
    use epoll;
    multi_accept on;
}

http {
    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    # Logging
    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for"';

    log_format upstream_time '$remote_addr - $remote_user [$time_local] '
                            '"$request" $status $body_bytes_sent '
                            '"$http_referer" "$http_user_agent" '
// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Use HTTP/2 for performance
• Enable SSL/TLS with strong ciphers
• Implement proper caching strategies
• Use upstream connection pooling
• Monitor with stub_status or prometheus
• Rate limit to prevent abuse
• Add security headers
• Use least_conn load balancing
• Keep error logs separate from access logs

❌ DON'T

• Disable gzip compression
• Use weak SSL ciphers
• Cache authenticated responses
• Allow direct access to backends
• Ignore upstream health checks
• Mix HTTP and HTTPS without redirect
• Use default error pages in production
• Cache sensitive user data
