Re: [modwsgi] Re: mod_wsgi importError
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

Re: [modwsgi] Re: mod_wsgi importError
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 :)

[modwsgi] Re: mod_wsgi importError
Thanks for the fast reply! I did what you`ve wrote and yay it worked! Now i wondering how can i tell to mod_wsgi two things - a) that wsgi file itself lies in /var/www/wsgi-scripts and b) that it should include python files from outside directory, for example home/user/flask_stuff_files ? -- You received this message because you are subscribed to the Google Groups "modwsgi" group.

[modwsgi] mod_wsgi importError
Good day, im trying to deploy a server on CentOs7 in combination
Flask+Apache 2.4+mod_wsgi 4.5.5. Mod_wsgi was compiled with python 3.5.2
and test-run from manual works fine. However when i tried to connect mine
app i failed so i reduced tests to only Apache+mod_wsgi stack and found
that somehow import of python modules isnt working. The simplest test ive
run is - ive got folder with wsgi file and some function deployed in the
same folder.
insides of simple_app.wsgi:
---
import sys, os
sys.path.insert(0,os.getcwd())
import add
def application(environ, start_response):
status = '200 OK'
output = add.echo()
response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
return [output]
-
insides of add.py:
-
def echo():
return b'module import is fine'
-
Apache VirtualHost config:
-
ServerName www.example.com
DocumentRoot /var/www/html
WSGIScriptAlias /test /var/www/wsgi-scripts/simple_app.wsgi
Require all granted
Apache logs are telling:
...
[wsgi:error] [pid 11717] [client 83.220.186.194:56534] ImportError: no
module named 'add'
...
If i will leave the same Apache config, remove importing stuff from
simple_app.wsgi and as a result will return some byte string, like in this
code:
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]
everything will work just fine without errors and by opening
www.example.com/test i will see
"Hello, World!"
Since im totally newbie in Apache/mod_wsgi stuff all suggestions are
welcome!
