Flask FastCGI

FastCGI is another deployment option for Flask applications on web servers (such as nginix, lighttpd, and Cherokee).

Configure FastCGI

Firstly, you need to create a FastCGI server file, for example, its name is: yourapplication.fcgiC .

from flup.server.fcgi import WSGIServer
　from yourapplication import app
　if __name__ == '__main__':
　　　　　WSGIServer(app).run()

nginx and earlier versions of lighttpd require an explicit socket to communicate with the FastCGI server. The path needs to be passed to the WSGIServer's socket.

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

Configure Apache

For basic Apache deployment, .fcgi The file will appear in your application URL, for example http://example.com/yourapplication.fcgi/hello/There are several methods to configure the application so that yourapplication.fcgi does not appear in the URL.

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

Configure lighttpd

The basic configuration of lighttpd looks like this -

#　Filename　:　example.py

#　Date　:　2020-08-08
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"
　)

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