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
