Flask 简明教程

Flask – FastCGI

FastCGI 是适用于 nginix、lighttpd 和 Cherokee 等网络服务器的 Flask 应用程序的另一个部署选项。

FastCGI is another deployment option for Flask application on web servers like nginix, lighttpd, and Cherokee.

Configuring FastCGI

首先，您需要创建 FastCGI 服务器文件。让我们称之为 yourapplication.fcgi 。

First, you need to create the FastCGI server file. Let us call it yourapplication.fcgi.

from flup.server.fcgi import WSGIServer
from yourapplication import app

if __name__ == '__main__':
   WSGIServer(app).run()

nginx 和更早版本的 lighttpd 需要一个套接字来明确地传递与 FastCGI 服务器进行通信。要做到这一点，您需要将套接字的路径传递给 WSGIServer 。

nginx and older versions of lighttpd need a socket to be explicitly passed to communicate with the FastCGI server. For that to work, you need to pass the path to the socket to the WSGIServer.

WSGIServer(application, bindAddress = '/path/to/fcgi.sock').run()

Configuring Apache

对于基本的 Apache 部署，您的 .fcgi 文件将出现在您的应用程序 URL 中，例如 example.com/yourapplication.fcgi/hello/ 。有几种方法可以配置您的应用程序，以便 yourapplication.fcgi 不出现在 URL 中。

For a basic Apache deployment, your .fcgi file will appear in your application URL e.g. example.com/yourapplication.fcgi/hello/. There are few ways to configure your application so that yourapplication.fcgi does not appear in the URL.

<VirtualHost *>
   ServerName example.com
   ScriptAlias / /path/to/yourapplication.fcgi/
</VirtualHost>

Configuring lighttpd

lighttpd 的基本配置如下所示 -

Basic configuration of lighttpd looks like this −

fastcgi.server = ("/yourapplication.fcgi" => ((
   "socket" => "/tmp/yourapplication-fcgi.sock",
   "bin-path" => "/var/www/yourapplication/yourapplication.fcgi",
   "check-local" => "disable",
   "max-procs" => 1
)))

alias.url = (
   "/static/" => "/path/to/your/static"
)

url.rewrite-once = (
   "^(/static($|/.*))$" => "$1",
   "^(/.*)$" => "/yourapplication.fcgi$1"
)

请记住启用 FastCGI ，别名和重写模块。此配置将应用程序绑定到 /yourapplication 。

Remember to enable the FastCGI, alias and rewrite modules. This configuration binds the application to /yourapplication.
