Which one is better, nginx or apache?

Both Nginx and Apache are web server applications. In layman's terms, our websites require web server applications to be displayed to customers, and the server is the basis for the normal and stable operation of web server applications.

So choosing a good web server application will affect the performance of the website and even the user's browsing experience. The current mainstream web server applications are Nginx and Apache. Today I will explain to you why I always recommend you to use Nginx instead of Apache? (Recommended learning: nginx tutorial)

I won’t go into details about the introduction of Nginx and Apache. You can understand it by yourself on Baidu and Google. No more nonsense. Let’s go straight to the topic:

1. As a Web server: Compared with Apache, Nginx uses fewer resources, supports more concurrent connections, and reflects higher efficiency. This makes Nginx especially popular with web hosting providers.

In the case of high connection concurrency, Nginx is a good alternative to the Apache server; Nginx is one of the software platforms often chosen by bosses in the virtual host business in the United States. Able to support responses of up to 50,000 concurrent connections, thanks to Nginx for choosing epoll and kqueue as the development model.

Nginx as a load balancing server: Nginx can not only directly support Rails and PHP programs to serve externally internally, but also support external services as an HTTP proxy server. Nginx is written in C, and its system resource overhead and CPU usage efficiency are much better than Perlbal.

2, Nginx configuration is simple, Apache is complex, Nginx is particularly easy to start, and can run almost 7*24 without interruption, even if it runs for several months, it does not need to be restarted.

You can also upgrade the software version without interrupting service. The static processing performance of Nginx is more than 3 times higher than that of Apache. Apache's support for PHP is relatively simple. Nginx needs to be used with other backends. Apache has more components than Nginx.

3. The core difference is that Apache is a synchronous multi-process model, and one connection corresponds to one process; Nginx is asynchronous, and multiple connections (10,000 levels) can correspond to one process.

4. The advantage of Nginx is that it handles static requests and has low CPU memory usage. Apache is suitable for handling dynamic requests. Therefore, Nginx is generally used as a reverse proxy on the front end to resist the pressure, and Apache is used as the backend to handle dynamic requests.
