Django (1.6) + Apache2 - django

First time I setup Django and Apache, and I'm having a tough time. It's seems easy by following tutorials, but it doesn't seem to work.
Basically, the steps I followed (on Debian):
Install Django (and some libraries)
Install Apache2
Install mod_wsgi
Then I've put my Django app in /root/, so the path is something like :
root/
.Projet/
.myprojet/
.site/
. .#here the models.py, views.py, etc of my site
.myprojet/
. .#here the settings.py, wsgi.py
. .static/
. .#static files in folders
.templates
. .#my templates
.database.sql
.manage.py
Then in /etc/apache2 I created the file httpd.conf, with this inside :
WSGIScriptAlias / /root/Projet/myprojet/myprojet/wsgi.py
WSGIPythonPath /root/Projet/myprojet
<Directory /root/Projet/myprojet/myprojet>
<Files wsgi.py>
Order deny,allow
Allow from all
</Files>
</Directory>
I do a2enmod wsgi (it tells me "Module wsgi already enabled").
Then service apache2 restart (successful, but tells me I have no VirtualHosts).
When I go to my website (using the IP adress), just the Apache "It works" display.
Thank you for your help ^^

You shouldn't put your Apache configuration file in /etc/apache2/. The fact that you mention a2enmod implies that you are on a Debian-based distro like Ubuntu. For those systems, you need to give that file a name related to the app - call it django if you like - and put it in /etc/apache2/sites-available. Then you can run a2ensite django to link it to sites-enabled, restart Apache, and it should work.

Unabled to deploy django + apache on aws Ubuntu server

I am trying to deploy a Django Application using Apache on an Ubuntu Server, I am having a weird error (500 internal error server error) when using port :80.
I made some test using port :8000 running the command:
python3 manage.py runserver 0.0.0.0:8000
And the application is working without any problem there, but when I try to access the application using port 80 it does work.
My apache config file looks like this:
<VirtualHost *:80>
Alias /static /home/ubuntu/gh_system/static
<Directory /home/ubuntu/gh_system/static>
Require all granted
</Directory>
<Directory /home/ubuntu/gh_system/HRSYSTEM>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
WSGIDaemonProcess HRSYSTEM python-home=/home/ubuntu/gh_system/env python-path=/home/ubuntu/gh_system>
WSGIProcessGroup HRSYSTEM
WSGIScriptAlias / /home/ubuntu/gh_system/HRSYSTEM/wsgi.py
I reviewed the apached2 errors logs, and I am getting a: No module named 'django', my wsgi files is:
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "HRSYSTEM.settings")
application = get_wsgi_application()
After some research, testing and reviewing the apache logs with:
sudo tail -100 /var/log/apache2/error.log
I found that the problem was related to this line:
WSGIDaemonProcess HRSYSTEM ***python-home=/home/ubuntu/gh_system/env*** python-path=/home/ubuntu/gh_system>
Basically, apache was trying to read the packages inside of the virtual environment but I did install them using the command:
sudo pip3 install -r requirements.txt
Apparently, using the "sudo" command was installing the packages outside the virtual environment, it is so weird; but without "sudo" the console logs the error permission denied, so I give chmod 700 permission to the virtual environment and install again the packages without the "sudo", and then it works!
Some of the things I learned about the errors:
Problem: Not module 'encodings' --> this problem occurs when apache can not access your packages, usually for a bad path specified in the config file.
Problem: Not module 'x module, could be django' means you need to install the package using pip3.
Hope it helps someone! and just to point out, something I have been learning lately, is: when you spend too much time trying to solve a problem, and there is not much information about it on internet, it means that something really, really basic is failing in your project; for example, installing the packages outside the virtual environment without even realizing it, just like I did.

Server isnt recognizing python virtualenv anymore

I have a deployed Django app on a Centos 7 server. I ran into problems when git pulling from my repository. It doesn't recognize python-home at the location where my virtualenv is anymore.
When i print(sys.prefix), it shows '/usr', but when i activate my virualenv (source /path/to/virtualenv/bin/activate) it shows the correct path that is assigned to python-home in my httpd .conf file
.conf file
Alias /static /var/www/ek/static
<Directory /var/www/ek/static>
Require all granted
</Directory>
<Directory /var/www/ek/new>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
WSGIApplicationGroup %{GLOBAL}
WSGIDaemonProcess ek python-path=/var/www/ek python-home= /var/www/kpi_env
WSGIProcessGroup ek
WSGIScriptAlias / /var/www/ek/new/wsgi.py
I'm not exactly sure what the problem is, when im not in my virtualenv, should the prefix be the path to the virtualenv? Should print(sys.prefix) only show var/www/kpi_env when im in the virtualenv?
Whatever it is, it doesn't recognize python-home=/var/www/kpi_env as anything anymore.
When i change it to python-home = /usr it works but the application is giving me errors that i've never run into before on my server or on my workstation. This error being Permission denied is Server running on host 12.0.0.1 and accepting tcp con on port 5432 This is referring to postgresql, and i'm sure that it is running and accepting tcp connection on port 5432. And that my settings.py reflect the right configurations. I havent changed any configurations with changes with git pull and havent touched configs for postgresql at all, so i can only think that its because of the python library it is using, because thats the only thing that has changed.
How do i make my httpd server recognize python-home= /var/www/kpi_envagain ?
This doesn't exactly answer what i asked but this was the workaround i did:
I ran this command to allow my httpd server to accept the connection to my postgresql database,
setsebool -P httpd_can_network_connect_db 1
-P will do this permanently and 1 will set it to on.
And in this, i used python-home = /usr since i couldnt get my virtualenv to work anymore

Django project doesn't show up with Apache and mod_wsgi

I've installed Apache and mod_wsgi on windows xp service pack 3 and added these line to my httpd.conf :
WSGIScriptAlias / "C:/Documents and Settings/X/My Documents/Downloads/Foo/Foo/wsgi.py"
WSGIPythonPath "C:/Documents and Settings/X/My Documents/Downloads/Foo"
<Directory "C:/Documents and Settings/X/My Documents/Downloads/Foo/Foo">
<Files wsgi.py>
Require all granted
</Files>
</Directory>
but when I open localhost on my firefox, it shows Apache's It Works! message, what should I do to run my project on localhost ?
EDIT :
I checked and recognized that my project's path is not included in PYTHONPATH. Isn't the line WSGIPythonPath ... expected to add the address to PYTHONPATH ?
Alright, so my setup is in linux so this is not tested on windows, but:
I did not see your LoadModule statement
File: httpd.conf
LoadModule wsgi_module modules/mod_wsgi.so
modwsgi wont work without that.
Also: the your grant statement seems a bit suspicious.
In the wsgi configuration guide suggests using a Directory directive for allowing this access to your mod_wsgi application.
<Directory "C:/Documents and Settings/X/My Documents/Downloads/Foo/Foo/">
Order allow,deny
Allow from all
</Directory>
Finally:
Make your life easy down the road.
configure apache in worker mode
configure mod_wsgi in daemon mode.
profit
Might I suggest watching this PyCon talk Making Apache suck less for hosting Python web applications from 'the-man' Graham. I wish I knew all of that stuff years ago.
Note: To figure out if you have apache in mpm worker mode.
httpd.exe -V
look for the "Server MPM" value of worker.
Django runs on port 8000 so you'll want to do two things. First, you need to run the server by entering into your console python manage.py runserver. Second, you need to direct your browser to localhost:8000.
As an aside, you don't need Apache to run a simple, local development environment. Django has its own server built in that you can leverage.

Configuring Apache 2 with mod_wsgi for Django - no httpd.conf file

I am using Apache 2 on raspbian os. I read somewhere that in the newest versions of Apache there is no httpd.conf file, is this true? [Edit] (This is true)
My apache server is running (I can see the default web page), and mod_wsgi is successfully installed. So I began the instructions here for using django 1.5 with apache. However it tells me I need to add the following lines to the httpd.conf file:
WSGIScriptAlias / /path/to/mysite.com/mysite/wsgi.py
WSGIPythonPath /path/to/mysite.com
<Directory /path/to/mysite.com/mysite>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
However, there is no httpd.conf file present in my version of apache. I have checked /etc/httpd/confand /etc/apache2 for the http.conf file. /etc/apache2 is where apache is though.
In short, where should I add the required settings so that apache recognizes mod_wsgi.
Possibly, many distros use
/etc/apache2/apache2.conf
Instead. However you shouldn't really edit that and it affects apache2 globally, i.e. all you sites (virtual-hosts). If you have only the one site better edit the contents of:
/etc/apache2/sites-available/default
The Ubuntu Apache2 configuration documentation is a good getting started guide: https://help.ubuntu.com/14.04/serverguide/httpd.html#http-configuration
Here is tutorial configuring Apache2 with mod_wsgi for Django on Ubuntu 11.04 wihtout httpd.conf: http://blog.madspace.me/configure-python-django-with-apache/, and one on 12.04: http://www.lennu.net/2012/05/14/django-deployement-installation-to-ubuntu-12-dot-04-server/

I need help on configuring mod_wsgi and Django

Apache & mod_wsgi are configured correctly (I've created a hello
world .html apache file and a hello world mod_wsgi application with
no problems). I now need my Django app to work with my django.wsgi
file. What makes me think that it's not recognizing my wsgi file is that I
went into my django.wsgi file I created and completely deleted all of
the code in the file and restarted Apache and it still gives me the
same page (a listing of the files from Django app, not my actual
Django application. Configuring Apache and mod_wsgi went really well
but I'm at a loss of how to fix this. Here are some details:
Here is my current django.wsgi file:
import os
import sys
sys.path.append('/srv/www/duckling.org/store/')
os.environ['DJANGO_SETTINGS_MODULE'] = 'store.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
I've tried a few different versions of the django.wsgi file
(including a version like the one over at http://www.djangoproject.com/).
This version of my wsgi is from here:
http://library.linode.com/frameworks/django-apache-mod-wsgi/ubuntu-10...
Also, here is my vhost apache configuration file below. I think these
are the main files that are suppose to do the job for me. Let me know if
you see any errors in what I'm doing and what else I might do to fix
this. The django app runs fine on the django's built-in development
server so I'm thinking it might have something with my paths.
No errors in my apache error.log file as well. It's acting as there's
no problem at all, which is not the case...the project isn't loading,
like I said just a listing of my files and directories of my Django
project. Here is my apache config file:
<VirtualHost 1.2.3.4:80>
ServerAdmin hi#duckling.org
ServerName duckling.org
ServerAlias www.duckling.org
DocumentRoot /srv/www/duckling.org/store/
<Directory /srv/www/duckling.org/store/>
Order Allow,Deny
Allow from all
</Directory>
Alias /static/ /srv/www/duckling.org/store/static/
<Directory /srv/www/duckling.org/store/static>
Order deny,allow
Allow from all
</Directory>
WSGIScriptAlias store/ /srv/www/duckling.org/store/wsgi-scripts/django.wsgi
<Directory /srv/www/wsgi-scripts>
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
And here are versions of the stack that I'm using, I saw over at the
mod_wsgi site that you all would like the versions of what I'm using
on the server:
Apache/2.2.14 (Ubuntu) PHP/5.3.2-1ubuntu4.5 with Suhosin-Patch
mod_python/3.3.1 Python/2.6.5 mod_wsgi/2.8
thanks,
j.
For a start, you should definitely not keep your Django files under your DocumentRoot. There's no need for them to be there, and it's a potential security risk - as you've seen, your current misconfiguration allows Apache to serve up your files directly: an attacker could guess that and download your settings.py, complete with your database password.
So, get rid of that DocumentRoot directive completely, as well as the first Directory section which allows direct access to /srv/www/duckling.org/store/. (You probably don't need the one serving up /srv/www/wsgi-scripts either.) That should make things a bit better.
By the way, this configuration will serve your website under duckling.org/store - is that what you want? If you want it under the root, you should just use:
WSGIScriptAlias / /srv/www/duckling.org/store/wsgi-scripts/django.wsgi
