Django application not running with Gunicorn and Supervisor

Question

I am trying to run a Django application from gunicorn and supervisord. I have configured bash script to run application from gunicorn which is working fine and I am able to see the GUI but when I was trying to start this application from supervisorctl. I am not able to see the GUI. However, Gunicorn processes are running.

gunicorn_start2

export ANALYTICS_ENV="dev"

It seems that the issue is with the environmental variable. Because when I am trying to run python manage.py runserver then its also not working. But when I am running ANALYTICS_ENV=dev python manage.py runserver then it's working.

However, I am unable to run it with gunicorn in anyway.

Any idea?

This has been solved by below steps.

1. source virtualenv
2. Export ANALYTICS_ENV.
3. Export PYTHONPATH of virtualenv.

Supervisor Configuration:

[program:analytics]
command = gunicorn analytics.wsgi:application --name analytics --workers 4 --user=ubuntu --timeout=3600 --bind 127.0.0.1:8000 ; Command to start app
user = ubuntu ; User to run as
stdout_logfile = /home/code/example/gunicorn_start2.log ; Where to write log messages
redirect_stderr = true ; Save stderr in the same log
environment=LANG=en_US.UTF-8,LC_ALL=en_US.UTF-8,ANALYTICS_ENV=dev,PYTHONPATH=/home/ubuntu/code/current/analytics/bin/python ; Set UTF-8 as default encoding
