Comprehensive Guide to Nginx Configuration, Optimization, and Deployment

For front‑end developers who need to work with Nginx, this guide reorganizes the default configuration file and explains each part to build a solid overall understanding.

The core file nginx.conf is introduced, showing the original verbose version and a cleaned‑up version with comments removed, reducing it to 22 lines.

Three main sections of nginx.conf :

Global block – sets worker processes, user, PID, log paths, and includes.

Events block – controls network connection handling, worker connections, and event models.

Http block – contains most server directives, including MIME types, sendfile, keepalive, and server blocks for virtual hosts.

Key directives are explained with annotated examples, e.g., worker_processes 1; determines concurrency, and worker_connections 1024; sets the maximum connections per worker.

Basic Nginx commands:

yum install nginx

netstat -anput | grep nginx

netstat -ntlp

nginx

nginx -s reload

nginx -s stop

nginx -s quit

nginx -t

Note: changes to nginx.conf require a reload, while updating static files does not.

Optimization tips:

History‑mode 404 handling: location / { try_files $uri $uri/ /index.html; }

Reverse proxy example: location /police/ { proxy_pass http://192.168.1.182:8852/police/; proxy_redirect default; proxy_http_version 1.1; proxy_connect_timeout 60; proxy_send_timeout 60; proxy_read_timeout 90; }

Enable gzip compression: gzip on; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; (additional optional settings are shown)

Maintenance page toggle: # rewrite ^(.*)$ /maintainace.html break;

Multiple sites on one IP using separate server blocks with different ports and roots.

Static‑dynamic separation using dedicated location blocks for images, static assets, and other file types.

These configurations provide a solid foundation for deploying a website, handling cross‑origin requests, and improving performance.
