And does /var/www/flask_stuff_files/templates/analysis exist? Does it have to 
be a directory or a file? For uploads those directories will need to be 
writable to Apache user.

Re: [modwsgi] Re: mod_wsgi importError

[Tierprot B.]

Hmm and now im more confused, i copied server files from
/home/user/flask_stuff_files
to the new directory /var/www/flask_stuff_files and corrected Apache conf,
now it looks like:

apache-wsgi config:


  ServerName www.example.com
  DocumentRoot /var/www/flask_stuff_files/templates
  WSGIDaemonProcess home=/var/www/wsgi-scripts python-path=/var/www
/flask_stuff_files user=user group=user
  WSGIScriptAlias /test /var/www/wsgi-scripts/simple_app.wsgi
process-group=app application-group=%{GLOBAL}

  
  Require all granted
  

 

Still main page www.example.com/test renders ok, but on files submission i
get error File does not exist: /var/www/flask_stuff_files/templates/analysis,
referer: http://www.example.com/test

What are you trying to have happen by adding this?

The Apache user would need access to that directory and once agains the 
permissions on the directories are such that that can’t happen. Changing user 
for mod_wsgi daemon process group only affects access to Python code, not 
static files Apache tries to serve up.

In general this is why is better not to have anything for your application 
under your home directory. Better under separate directory for project under 
/var/www.

May not need this entry for /home/user/flask_stuff_files.

May not need this entry for /home/user/flask_stuff_files/templates. Depends on 
answer about DocumentRoot.

The Directory block and access grants is only needed for where the WSGI script 
file is located.

The WSGIScriptAlias already specifies process-group and application-group so 
the WSGIProcessGroup and WSGIApplicationGroup not needed either.

Re: [modwsgi] Re: mod_wsgi importError

[Tierprot B.]

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:


  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}

  
  Require all granted
  

  
  WSGIProcessGroup app
  WSGIApplicationGroup %{GLOBAL}
  Require all granted
  

  
  WSGIProcessGroup app
  WSGIApplicationGroup %{GLOBAL}
  Require all granted
  

 

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?

Ok, ive got python modules which i try to import located at 
home/user/flask_stuff_files, 
mine wsgi file is in /var/www/wsgi-scripts, now to the code:

apache-wsgi config:


  ServerName www.example.com 
  DocumentRoot /var/www/html

  WSGIDaemonProcess home=/var/www/wsgi-scripts python-path=
home/user/flask_stuff_files
  WSGIScriptAlias /test /var/www/wsgi-scripts/simple_app.wsgi
  
  
  Require all granted
  
 
-

simple_app.wsgi:
--
import server_handle

def application(environ, start_response):
status = '200 OK'
output = b'Hello, World!'

response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
return [output]



server_handle.py module is located at /home/user/flask_stuff_files

on trying www.example.com/test Apache spits with error ImportError: no 
module named 'server_handle'  

adding of code like:

import sys
sys.path.insert(0,'/home/user/flask_stuff_files')

dont solve the problem too (do you know why, btw?)

Theres something i didn`t properly understood, so sorry for annoying and 
dumb questions :)

That is what WSGIScriptAlias is doing in giving it the path to the WSGI script 
file. If you mean something different you need to be clearer.

If you are talking about other places to look for Python modules to import, 
that is what the python-path option for WSGIDaemonProcess that I mentioned is 
for.
