Can you guys help me please! This is driving me crazy. I have googled the problem but can't find an answer. When I run the command ./gunicorn_start I get this error:

I can run gunicorn wrw.conf.wsgi:application --bind 127.0.0.1:8000 and the application runs fine and I can access it from the web.

I have checked and double check your gnuicorn_start script but can not find anything I copied wrong.

So from what I understand the user www-data and the group www-data does not have permissions?
From the book:

"USER and GROUP are used to set Gunicorn to run as www-data, which is a user created
during our installation that is most often used to run web/app server. This is for security
concerns to limit access to the system."

But I do not remember creating them on installation when I followed the book.

My memory may be a bit foggy here but I believe thouse users should be created by the package manager when installing via apt-get (Debian based distros). Can you list out the steps you followed to install / setup gunicorn so far?

Cheers,
Jeremy

I am using Ubuntu 14.04

cd /opt/wrw/
workon wrw
pip install gunicorn
vim deploy/gunicorn_start

Then copied the instructions changing the directories and settings based on my set-up

I looked at the processes running and the nginx process has user: www-data and group: www-data
So they where created by the system. But now then how to I give them permission to run the gunicorn_start script.
