gunicorn

问题 First of all please let me be clear that I am a windows user and very new to the web world. For the past months I have been learning both python and django, and it has been a great experience for me. Now I have somehow created a small project that I would like to deploy in the production server. Since django has its built-in development server there was no problem for me.

问题 I read this about Tornado: On the other hand, if you already have a WSGI app and want to run it on a blazing fast tornado.httpserver.HTTPServer, wraps it with tornado.wsgi.WSGIContainer. But you need to be careful. Since your original application is not prepared for an asynchronous server, and will make a lot of IO/computation, it will block other requests while generating a response (further requests will be accepted and buffered but queued for later handling). And Guincorn says: 'a Python

问题 I'm deploying a ML model for the first time. I'm using flask-restful to create a rest api and gunicorn as stand-alone WSGI.my project directory has only 2 files , ML_model.py and rApi.py. i installed gunicorn and ran the server using gunicorn -w 4 -b 127.0.0.1:5000 rApi:app and i'm able to use the restAPi. I see many things like .env , .config and wsgi.py files mentioned in tutorials available online. what am I missing. why do i need all those files if i can use the API already? 回答1: I see

问题 I am trying to run a Docker container locally, via the command: docker run --rm -d mellon:latest The gunicorn command which is executing is: gunicorn -b 0.0.0.0:8000 mellon.wsgi (more specifically in the Dockerfile): ...

问题 While reading the docs of running Uvicorn: Gunicorn is a mature, fully featured server and process manager. Uvicorn includes a Gunicorn worker class allowing you to run ASGI applications, with all of Uvicorn's performance benefits, while also giving you Gunicorn's fully-featured process management. Is doc wrong or i didn't understand correctly? from my understanding, Gunicorn has a master slave structure to allow Uvicon class (async sever) to run in separate worker classes using command:

问题 I have my website finally working properly, but media files aren't served when debug = False what should I do? I've went through hell trying to make it work with nginx following this tutorial but it kept breaking and not serving static among other things, so I went with pure gunicorn and whitenoise. I really am not an expert at deploying, only development. Please help. Security isn't a problem with media files because only the admin can upload them, not end-users. Specifically I need to know

问题 I'm new to Flask/Gunicorn and have a very basic understanding of SQL. I have a Flask app that connects to a remote oracle database with cx_oracle. Depending on the app route selected, it runs one of two queries. I run the app using gunicorn -w 4 flask:app . The first query is a simple query on a table with ~70000 rows and is very responsive.
