This article is to share with you about the comparison of the advantages and disadvantages of Apache and nginx. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

First, the advantages of apache over nginx:

Rewrite is more powerful than nginx's rewrite.

Dynamic pages, nginx to deal with dynamic requests is a chicken rib, generally dynamic requests need to be done by apache, nginx is only suitable for static and reverse.

There are so many modules that you can find anything you can think of.

Less bug, more bug in nginx

Second, the advantages of nginx over apache:

Lightweight, similar to web services, takes up less memory and resources than apache, supports more concurrent connections, and embodies higher efficiency, which makes Nginx especially popular with web hosting providers. In the case of high connection concurrency, Nginx is a good alternative to Apache servers: Nginx is one of the software platforms often chosen by web hosting bosses in the United States. It can support responses of up to 50000 concurrent connections, thanks to Nginx choosing epoll and kqueue as the development model for us.

Anti-concurrency, nginx processes requests asynchronously and non-blocking, while apache is blocking. Under high concurrency, nginx can maintain low resources, low consumption and high performance.

Highly modular design, relatively simple to write modules

The community is active and all kinds of high-performance modules are produced quickly.

Nginx itself is a reverse proxy server

The load balancing ability is outstanding. Nginx can not only directly support Rails and PHP programs to serve externally, but also support external services as HTTP proxy servers. Nginx is written in C, both the system resource overhead and the efficiency of CPU are much better than Perlbal.

III. Core differences

Apache is a synchronous multi-process model, with one connection corresponding to one process; nginx is asynchronous, and multiple connections (ten thousand levels) can correspond to one process.

Fourth, the comparison of their advantages and disadvantages.

Nginx configuration is simple and Apache is complex.

The static processing performance of Nginx is 3 times higher than that of Apache.

It is relatively simple for Apache to support PHP, and Nginx needs to be used with other backends.

Apache has more components than Nginx

Apache is a synchronous multi-process model, with one connection corresponding to one process.

Nginx is asynchronous, and multiple connections (level 10,000) can correspond to one process

Nginx handles static files well and consumes less memory.

Dynamic requests are done by apache, and nginx is only suitable for static and reverse.

Nginx is suitable to be a front-end server with good load performance.

Nginx itself is a reverse proxy server and supports load balancing.

V. Summary

Nginx advantages: load balancing, reverse proxy, the advantage of handling static files. Nginx processes static requests faster than apache

Advantages of Apache: rewrite is powerful and dynamic request capability is strong.

The above is the comparison of the advantages and disadvantages of Apache and nginx. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
