nginx (13: Permission denied) on socket
Solution 1:
After a few hours of pain I found a solution to this exact issue.
The problems are two: 1) the folder's permissions 2) the virtual environment
The virtual environment messes with your permissions and prevents uwsgi from creating the socket correctly - just deactivate the venv and pip install django and uwsgi system wide. There may be a way to solve this within the venv, but I don't know of any.
Then, set your django project folder's permissions to 777 (or change its owner to root).
cd into the folder and run the wsgi command as root:
sudo uwsgi --socket mysite.sock --module mysite.wsgi --chmod-socket=664 --uid www-data --gid www-data
this creates mysite.sock with owner www-data and I no longer get the permission denied error.
I hope this helps.
-edit- after some more investigation, I followed this tutorial and got it working as a systemd service without any of these issues - I guess the official tutorial takes some things for granted.
