带有 SSL 的猎鹰服务器在几个小时/几天后停止工作

Question

I set up a very basic Python API server with falcon along the example given in the documentation . And it seems to work just fine.

Now I extended the code to support HTTPS requests using SSL certificates

import ssl

httpd = simple_server.make_server('', 8000, app)
httpd.socket = ssl.wrap_socket(
        httpd.socket, server_side=True,
        certfile='cert.pem',
        keyfile='key.pem')
httpd.serve_forever()

And again, it seems to work and HTTPS requests are served perfectly fine...in the beginning.

However, after a while -- maybe a few hours or 1-2 days (no heavy load during testing) -- the server hangs and no longer accepts any requests. Not even with Te.net I can make any kind of connection. The server script doesn't show any errors, and Ubuntu tells me that some process is still listening on this port.

Where do I go from here? I don't even know how to troubleshoot. With the basic HTTP server, I haven't experienced any issues so far

Answer 1

As discussed in the above comments, wsgiref 's simple_server isn't really suitable for production.

Assuming your application is contained in app.py , and you installed gunicorn into your current Python (virtual) environment, you can run your application with TLS as:

gunicorn -b 0.0.0.0:443 --workers 8 --certfile /path/to/your/cert/cert.pem --key=/pat/to/your/cert/privkey.pem --access-logfile - app:app

(You should of course tune the number of workers, threads, etc according to your application's needs.)
