Question: Trouble Setting up uWSGI + NGINX over socket

[liszca]

What I'm trying to do

Trying to run ImageTagger with uWSGI and NGINX over socket file

What I've tried

I first tried to follow this tutorial:
https://tonyteaches.tech/django-nginx-uwsgi-tutorial/

Additional context

In Tonys guide I am at 6. Get Nginx, uWSGI, and Django to Work Together testing my configuration.

after activating Venv I run following commands:

cd /var/django/it/imagetagger/imagetagger
uwsgi --socket /var/run/django/it.sock --module imagetagger.wsgi --chmod-socket=666

Output:

After the browser gave me an Internal Server Error and the terminal says no python application found:

--- no python application found, check your startup logs for errors ---

Variables I exported:

export IT_DB_PASSWORD
export DJANGO_CONFIGURATION
export IT_ALLOWED_HOSTS
export IT_DB_HOST
export IT_DOWNLOAD_BASE_URL
export IT_EMAIL_HOST
export IT_SECRET_KEY

Is there something I have to do in regards of missing variable DJANGO_SETTINGS_MODULE?

ImageTagger in general does work with the following commands (Variables are exported):

source /var/python3/venv/it/bin/activate
cd /var/django/it/imagetagger/imagetagger
 ./manage.py runserver 0.0.0.0:8000

Output after an request in the Browser:

Does it work if you set the environment variable DJANGO_SETTINGS_MODULE to imagetagger.settings?
