Master Nginx: From Basics to Advanced Configuration – Free Study Guide Inside

Why Nginx Became the Leading Web Server

Before Nginx, Apache dominated the web‑server market, but Nginx was created for performance optimization, offering high efficiency, stability, and mature code, which quickly made it the most popular web server.

Adoption by Major Chinese Internet Companies

Companies such as Baidu, JD.com, Tencent, NetEase, and Taobao rely on Nginx for their online services.

Core Capabilities of Nginx

Nginx can provide web services, load balancing (reverse proxy), and web caching.

Free "Nginx Study Notes" Overview

The free guide contains eight chapters (113 pages) covering web service basics, Nginx fundamentals, core configuration, advanced configuration, rewrite rules, reverse proxy, system parameter tuning, and an LNMP practical tutorial.

Fundamental Knowledge

Nginx is an open‑source, high‑performance HTTP server, reverse proxy, mail proxy, and TCP/UDP proxy. It uses a multi‑process model consisting of a master process and multiple worker processes.

Master Process Functions

Read and validate Nginx configuration files.

Create, bind, and close socket connections.

Manage worker processes according to the configuration.

Accept external commands such as restart, upgrade, or shutdown.

Perform graceful upgrades without interrupting service.

Open log files and obtain file descriptors.

Rollback on upgrade failure.

Compile and execute Perl scripts.

Worker Process Functions

Accept and process client requests.

Dispatch requests to appropriate modules.

Perform I/O operations to generate responses.

Communicate with backend servers and retrieve results.

Cache data and query cache indexes.

Send response data back to clients.

Handle commands from the master process (restart, upgrade, exit).

Core Configuration Details

The location directive is used to define request handling rules.

Four‑layer access control is implemented via the ngx_http_access_module, allowing IP‑based restrictions.

File existence checks can be performed using the if and try_files directives.

Advanced Configuration and Reverse Proxy

Reverse proxy forwards external requests to internal web servers and returns the data to the client.
