Aha! Thanks! Addition of proper user and group options to WSGIDaemonProcess
solved the ImportError! The last question i have might be not related to
mod_wsgi directly, but still.
I have a Flask app, purpose of which to be able to upload files provided by
user, do some math and return result on a new page. Simplified code looks
like this:
...
@app.route('/'):
def index()
return render_template('index.html')
@app.route('/analysis', methods=['POST'])
def upload():
uploaded_files = request.files.getlist('files')
...
for file in uploaded_files:
...
return render_template('analysis.html')
...
The folder with static files which Flask renders is:
home/user/flask_stuff_files/templates
in Apache ive corrected document root folder and added directory with
static files:
apache-wsgi config:
----------------------------
<VirtualHost *:80>
ServerName www.example.com
DocumentRoot /home/user/flask_stuff_files/templates
WSGIDaemonProcess home=/var/www/wsgi-scripts python-path=
/home/user/flask_stuff_files user=user group=user
WSGIScriptAlias /test /var/www/wsgi-scripts/simple_app.wsgi
process-group=app application-group=%{GLOBAL}
<Directory /var/www/wsgi-scripts>
Require all granted
</Directory>
<Directory /home/user/flask_stuff_files>
WSGIProcessGroup app
WSGIApplicationGroup %{GLOBAL}
Require all granted
</Directory>
<Directory /home/user/flask_stuff_files/templates>
WSGIProcessGroup app
WSGIApplicationGroup %{GLOBAL}
Require all granted
</Directory>
</VirtualHost>
So, www.example.com/test - it renders main page as intended, but when i
select files and submit them via POST request ive got a forbidden access
with error_log : Permission denied [...] : acces to /analysis denied
(filesystempath '/home/user/flask_stuff_files') because search permissions
are missing on a component of the path, referer: www.example.com/test.
For the test, i set permissions of the folder /home/user/flask_stuff_files
to the drwxrwxrwx, it belongs to user user.
So, could you share your thoughts on what is wrong here?
