Nginx

Nginx is a high-performance HTTP and reverse proxy service, and also an IMAP/POP3/ SMTP service.

1. Process response requests quickly

2. High concurrent connections

3. Low memory consumption

4. High reliability ：

5. High scalability

6. Hot deployment

The separation design of the master management process and the worker process makes Nginx have the function of hot deployment and can be deployed in 7 × Under the premise of 24-hour uninterrupted service, upgrade the Nginx executable file. You can also modify configuration files, replace log files and other functions without stopping the service.

7. Free BSD License Agreement

OpenResty (also known as ngx_openresty)

OpenResty is a high-end software based on Nginx and Lua A high-performance web platform that integrates a large number of sophisticated Lua libraries, third-party modules and most dependencies.

Used to easily build dynamic web applications, web services and dynamic gateways that can handle ultra-high concurrency and high scalability.

OpenResty effectively turns Nginx into a powerful universal web application platform by bringing together various well-designed Nginx modules (mainly developed independently by the OpenResty team). In this way, web developers and system engineers can use the Lua scripting language to mobilize various C and Lua modules supported by Nginx to quickly construct a high-performance web application system capable of handling more than 10K or even 1000K single-machine concurrent connections.

The goal of OpenResty is to let your Web service run directly inside the Nginx service, making full use of Nginx's non-blocking I/O model, not only for HTTP client requests, but also for remote backends Such as MySQL, PostgreSQL, Memcached and Redis all provide consistent high-performance response.

NGINX can be used to serve files and manage traffic. 1) Configure NGINX service static files: define the listening port and file directory. 2) Implement load balancing and traffic management: Use upstream module and cache policies to optimize performance.

NGINX vs. Apache: Comparing Web Server TechnologiesMay 02, 2025 am 12:08 AM

NGINX is suitable for handling high concurrency and static content, while Apache is suitable for dynamic content and complex URL rewrites. 1.NGINX adopts an event-driven model, suitable for high concurrency. 2. Apache uses process or thread model, which is suitable for dynamic content. 3. NGINX configuration is simple, Apache configuration is complex but more flexible.

NGINX and Apache: Deployment and ConfigurationMay 01, 2025 am 12:08 AM

NGINX and Apache each have their own advantages, and the choice depends on the specific needs. 1.NGINX is suitable for high concurrency, with simple deployment, and configuration examples include virtual hosts and reverse proxy. 2. Apache is suitable for complex configurations and is equally simple to deploy. Configuration examples include virtual hosts and URL rewrites.
