Comprehensive Nginx Configuration, Optimization, and Deployment Guide

The article begins with a preface explaining why front‑end developers need to grasp Nginx and introduces the core nginx.conf file, which can appear overwhelming at first glance.

It then presents the original configuration (118 lines) and a cleaned‑up version (22 lines) after removing comments, followed by an annotated version that explains each directive such as worker_processes , worker_connections , sendfile , and keepalive_timeout .

Next, the guide breaks the configuration into three logical sections:

Global block – settings affecting the whole Nginx server (user, worker processes, PID, logs, includes).

Events block – network‑connection parameters like worker_connections and event models.

Http block – the most frequently used part, containing MIME types, file handling, server definitions, and location blocks.

For a simple site deployment, only two locations need modification: the server_name and root directives, allowing Nginx to serve static files from a specified directory.

The article then covers common optimizations:

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

Reverse proxy configuration for API requests: 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; }

Enabling gzip compression with typical mime types and performance‑tuning parameters.

Maintenance page activation via a commented rewrite rule.

Hosting multiple websites on a single IP by defining separate server blocks with different ports and root directories.

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

Finally, the guide lists essential Nginx commands for installation, process inspection, port checking, starting, reloading, stopping, and testing the configuration:

yum install nginx

netstat -anp | grep nginx

netstat -ntlp

nginx

nginx -s reload

nginx -s stop

nginx -s quit

nginx -t

These instructions equip readers with a clear understanding of Nginx’s structure, practical configuration examples, and deployment best practices.
