mod_wsgi: Exception occurred processing WSGI script (django deployment)

Question

I'm trying to deploy a django project with the following Apache configuration:

Apache virtualhost configuration

<Virtualhost *:80>
    DocumentRoot /var/www/project/backend
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    WSGIDaemonProcess backend python-home=/var/www/project/myenv python-path=/var/www/gestor_documental/backend

    WSGIProcessGroup backend
    WSGIScriptAlias / /var/www/project/backend/backend/wsgi.py process-group=backend
    Alias /static/ /var/www/project/backend/static/

    <Directory /var/www/project/backend>
            Require all granted
    </Directory>
</Virtualhost>

wsgi.load file

LoadModule wsgi_module "/var/www/project/myenv/lib/python3.5/site-packages/mod_wsgi/server/mod_wsgi-py35.cpython-35m-x86_64-linux-gnu.so"
WSGIPythonHome "/var/www/project/myenv"

The wsgi.py is the one django brings by default

wsgi.py

import os
from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "backend.settings")

application = get_wsgi_application()

This is the project tree:

project
|- backend
|  |- api (django app)
|  |- backend
|     |- ...
|     |- settings.py
|     |- wsgi.py
|-- myenv (virtualenv)

And this is the error log I keep getting when i try to load the web:

mod_wsgi (pid=38953): Failed to exec Python script file '/var/www/project/backend/backend/wsgi.py'.
mod_wsgi (pid=38953): Exception occurred processing WSGI script '/var/www/project/backend/backend/wsgi.py'.

ImportError: No module named 'backend'

I've followed every single tutorial and try tons of configurations but still getting the same error.

I'm using python 3.5.2 in a virtualenv and Apache 2.4.18

I've installed mod_wsgi via pip3.

Could someone help me with this and tell me what am i doing wrong?

Thank you.

Answer 1

I solved it changing the wsgi.py file adding the next lines:

import sys

sys.path.append('/var/www/project/backend')

I don't know if this is the correct answer but it actually worked with this workaround.

Answer 2

Its this line in the wsgi.py:

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "backend.settings")

There's no backend.settings in project/backend/backend. It's trying to find a third backend folder, so remove backend from that line.
