nginx - Gunicorn和Nginx之间的区别

Question

这是一个初学者的问题，但是我很难理解Gunicorn和Nginx之间的抽象。我不是在寻找详细的答案，只是在更高层次上，每个角色扮演什么角色？他们如何互动？

Answer 1

对于Gunicorn's deploy doc，我的理解是您将Nginx用作Gunicorn的代理服务器。

由于Gunicorn是从Ruby's Unicorn移植的，因此我假设Unicorn的限制和规格也适用于Gunicorn:

Unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels. Slow clients should only be served by placing a reverse proxy capable of fully buffering both the request and response in between Unicorn and slow clients.

Gunicorn's deploy doc说的差不多。

Although there are many HTTP proxies available, we strongly advise that you use Nginx. If you choose another proxy server you need to make sure that it buffers slow clients when you use default Gunicorn workers. Without this buffering, Gunicorn will be easily susceptible to denial-of-service attacks.

因此，Gunicorn为快速，低延迟的高带宽客户端提供服务，而Nginx为其余部分提供服务。
