Setting up Apache to serve the django admin files - django

In my apache.conf file (see code below°), VirtualHost port 80 configuration works fine. However, in the port 443, the Alias /admin/media/ /usr/local/lib/python2.7/site-packages/django/contrib/admin/media/ shows two issues:
my settings.py has : STATIC_URL = '/m/' and ADMIN_MEDIA_PREFIX = STATIC_URL + 'admin/'
my admin directory is : /home/user/project/virtual-environment/lib/python2.7/site-packages/django/contrib/admin/static/admin/
When I put Alias /m/admin/ /home/user/project/virtual-environment/lib/python2.7/site-packages/django/contrib/admin/static/admin/ it shows error 403 access forbidden.
When I add:
<Directory "/home/user/project/virtual-environment/lib/python2.7/site-packages/django/contrib/admin/static/admin/">
Require all granted
</Directory>
<Directory "/home/user/project/">
<Files django.wsgi>
Require all granted
</Files>
</Directory>
It shows error 404 not found with error_log saying :[wsgi:error] Target WSGI script '/home/user/project/django.wsgi' does not contain WSGI application 'application'
Could you please help me configure my apache virtualhost port 443 to server django admin app?

You have a number of things wrong or sub optimal with your configuration.
The first is that when using mod_wsgi daemon mode and have only the one application, it is recommended you force use of the main Python interpreter context. This avoids problems with some third party Python modules that do not work with Python sub interpreters. To do this, add:
WSGIApplicationGroup %{GLOBAL}
to both VirtualHost definitions.
The second is that your SSL VirtualHost is not delegating the WSGI application to run in the same mod_wsgi daemon process group as non SSL VirtualHost defines. You need to add to the SSL VirtualHost:
WSGIProcessGroup askbot2
There is no need to add a WSGIDaemonProcess directive to the SSL VirtualHost as it is piggy backing off that setup in non SSL VirtualHost to avoid multiple copies of application. Right now you have an even bigger problem in that the SSL variant is running in embedded mode, with is even less desirable scenario.
The third is that when setting up a Python virtual environment, you should use the python-home option to refer to the root of the Python virtual environment and not use python-path to refer to site-packages. For details on that see:
http://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html
The fourth problem is how you are dealing with Django initialisation failing. There is no need to to use the try/except around creating the WSGI application object. What you should do if using mod_wsgi daemon mode is use a modern mod_wsgi version (not likely the ancient version your OS packages provide), and set the startup-timeout option on the WSGIDaemonProcess directive. That option will automatically force a restart of process if WSGI script file fails to load within a certain time. For details on that option see:
http://modwsgi.readthedocs.io/en/develop/configuration-directives/WSGIDaemonProcess.html
If you are not going to do that, you at least need to add a raise to the except part so that the exception is propagated back to mod_wsgi so it knows the WSGI script file couldn't be loaded. if you don't, mod_wsgi thinks the WSGI script file was loaded fine, but then when it looks for application can't find it and so generates a 404 response and the error your see.

Django: how to configure Apache to serve Django apps with mod_wsgi

I tried to set up a Django app with Apache and mod_wsgi, but ran into a problem that I have no ideas where is the cause. The app works fine with the command "python manage.py runserver", but when I tried to run it with Apache, I got the following errors in the Apache error log file.

The file /data/partsdb/partsdb/wsgi.py just contains the following lines of codes.
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'partsdb.settings')
application = get_wsgi_application()
Upon a brief debugging, I found out that the errors were from this line in wsgi.py.
from django.core.wsgi import get_wsgi_application

Please note I used this for a single app running in daemon mode as suggested in the documentation, on a Ubuntu server. Check the permissions on the folders, in my case I had to change permissions to allow apache to read and write to the folders the site was in.
You can also look at the answer Graham Dumpleton gave a few years back here:

Django apache internal server error

I got "500 Internal Server Error", when I try to connect to my django project.
I try lots of way to setting the configuration file, include some method on stackoverflow. But I still can't solve the problem.Can someone help? Thank you very much.
This is my vhost wsgi config
<Directory "/home/antus/bazoo/Antus_Bazoo_Web">
<Files wsgi.py>
Require all granted
</Files>
</Directory>
WSGIDaemonProcess antus_bazoo python-
path=/home/antus/bazoo:/home/antus/bazoo/bazoo_env/lib/python3.7/site-
packages display-name=antus_bazoo python-home=/home/antus/bazoo/bazoo_env
WSGIProcessGroup antus_bazoo
WSGIScriptAlias / /home/antus/bazoo/Antus_Bazoo_Web/wsgi.py process-
group=antus_bazoo
This is the wsgi file
import os
import sys
import site
# Add the site-packages of the chosen virtualenv to work with
site.addsitedir('/home/antus/bazoo/bazoo_env/lib/python3.7/site-packages')

sys.path.append('/home/antus/bazoo/Antus_Bazoo_Web')
sys.path.append('/home/antus/bazoo/antus_bazoo')

fh = open('/home/antus/bazoo/wsgi_hello.txt', 'w')
fh.write('wsgi execution')
fh.close()
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
I do also save the errors in error log but it does not have anything to consider and even the file is not created.
UPDATE
This is the Vhost configuration.
<VirtualHost *:80>
ServerName mywebsite
ServerAlias www.mywebsite
ServerAdmin webmaster#mywebsite
DocumentRoot /home/antus/public_html
UseCanonicalName Off
ScriptAlias /cgi-bin/ /home/antus/public_html/cgi-bin/
# Custom settings are loaded below this line (if any exist)

</IfModule>
<Directory "/home/antus/public_html">
AllowOverride All
</Directory>
</VirtualHost>
The "500 Internal Server Error" would indicate something has gone wrong on the server and seeing that the wsgi.py has a file open operation, I'd looking for errors start there seeing as well that you mentioned something about "the file is not created".
fh = open('/home/antus/bazoo/wsgi_hello.txt', 'w')
The above line will not create a file. To create a file with open() use:
fh = open('/home/antus/bazoo/wsgi_hello.txt', 'w+')
Also a bit of the logs would go a great way in debugging this

How do I get Apache to reliably serve a large number of ports?

I have a dedicated server using Apache to listen to nine non standard ports (8xxx) which are supplying API services over SSL. Ports 80 and 443 are used to serve static content and an 'overwatch' service that indicates the status of the other services.
After a few days, the services start to fail because it appears that Apache is directing the service requests to the overwatch service rather than to the intended service. Restarting Apache fixes this issue until it happens again.
The services are implemented using wsgi.
There is a legacy pyramid API service configured as follows:
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
WSGIDaemonProcess pyramid user=ubuntu group=ubuntu threads=4 \
python-path=/home/ubuntu/ev_mis/lib/python2.7/site-packages
WSGIScriptAlias /mis /home/ubuntu/ev_mis/mis.wsgi
<Directory /home/ubuntu/ev_mis>
WSGIProcessGroup pyramid
Order allow,deny
Allow from all
</Directory>
The other eight API services use Django and are configured like this:
# Built automatically on Wed Sep 25 13:59:51 2013
Listen 8325
<VirtualHost _default_:8325>
DocumentRoot /usr/local/services/h/rb/mis/mis_site/mis_site
Alias /media /usr/local/services/h/rb/mis/mis_site/mis_site/media
Alias /static /usr/local/services/h/rb/mis/mis_site/mis_site/assets
<Directory /usr/local/services/h/rb/mis/mis_site/mis_site>
Order allow,deny
Allow from all
</Directory>
SetEnv DJANGO_SETTINGS_MODULE mis_site.settings.h
WSGIScriptAlias / /usr/local/orb_services/h/rb/mis/mis_site/mis_site/mis_site/wsgi.py
SSLEngine On
SSLCertificateFile /etc/apache2/ssl/domain.crt
SSLCertificateKeyFile /etc/apache2/ssl/domain.key
SSLCertificateChainFile /etc/apache2/ssl/chain.crt
SSLOptions +StrictRequire
</VirtualHost>
Finally there is the overwatch service configuration:
<VirtualHost *:80>
DocumentRoot /var/www
Alias /static /var/www/static
<Directory /var/www/>
Order allow,deny
Allow from all
</Directory>
Alias /thumbnails /var/www/thumbnails
<Directory /var/www/thumbnails>
Order allow,deny
Allow from all
</Directory>
WSGIScriptAlias / /var/www/overwatch/overwatch/wsgi.py
ErrorLog ${APACHE_LOG_DIR}/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
This is an example wsgi.py file:
import os
from os.path import abspath, dirname
from sys import path
from os import environ
SITE_ROOT = dirname(dirname(abspath(__file__)))
path.append(SITE_ROOT)
from django.core.wsgi import get_wsgi_application
def application(req_environ, start_response):
environ["DJANGO_SETTINGS_MODULE"] = req_environ.get("DJANGO_SETTINGS_MODULE",
environ.get("DJANGO_SETTINGS_MODULE",
None))
return get_wsgi_application()(req_environ, start_response)
For example: https://example.com/ yields the overwatch status table and https://example.com:8123/data/ yields service data on one of the services.
Analysis reveals that apache has mis-directed the call to the overwatch service. For example https://example.com:8123/data/ now yields page not found the debug trace reveals that it has been served by the overwatch wsgi service.
Once this happens, it happens consistently until I restart the apache service. Then everything is fine for a few days until it happens again. Apache does not report any configuration issues and starts/restarts fine.
Currently the server is only experiencing very light test traffic but it is scheduled to go live soon and I have no idea how to address this issue... short of perhaps biting the bullet and delaying launch while I reconfigure the whole thing to use nginx/gunicorn instead of apache which feels like a cop out.
A few comments.
You should not set DocumentRoot to a directory above where your project code is. If you were to inadvertently comment out the WSGIScriptAlias, all your project code, including the settings file with database passwords could be downloaded by someone.
You can't use 'SetEnv DJANGO_SETTINGS_MODULE mis_site.settings.h' in Apache to specify where the Django settings module is. It needs to be set in the wsgi.py file.
Why aren't you using daemon mode of mod_wsgi for your Django sites as well? You would be running multiple instances in sub interpreters of the one process and if you aren't configuring Django correctly, that could result in requests being handled by the wrong application. See http://blog.dscpl.com.au/2012/10/requests-running-in-wrong-django.html
UPDATE 1
Instead of using:
from django.core.wsgi import get_wsgi_application
def application(req_environ, start_response):
environ["DJANGO_SETTINGS_MODULE"] = req_environ.get(
"DJANGO_SETTINGS_MODULE". environ.get("DJANGO_SETTINGS_MODULE", None))
return get_wsgi_application()(req_environ, start_response)
You should be using:
from django.core.wsgi import get_wsgi_application
_application = get_wsgi_application()
def application(req_environ, start_response):
environ["DJANGO_SETTINGS_MODULE"] = req_environ.get(
"DJANGO_SETTINGS_MODULE", environ.get("DJANGO_SETTINGS_MODULE", None))
return _application(req_environ, start_response)
You are calling get_wsgi_application() on every request, which is a bad idea. It causes a new instance of the WSGI handler to be created on each request, which is not necessary. Doing so will also screw up the operation of monitoring tools such as New Relic.

Issues in django deployment with two subdomains using Apache auth

I'm deploying a Django 1.5 with two sites, each one is independent from the other one (each one has its own database), but these two sites are subdomains: one is new.mydomain.com and the other dev.mydomain.com. I'm using Apache with mod_wsgi.
The problem is: I'm Authenticating against Django’s user database from Apache correctly, but when I try to use Django groups with the Apache authentication I get the following situation:
I can login to one of the subdomains e.g. new without problems, but if I try to login to the other one (dev) I can't. Apache says that the user isn't in the allowed groups. Then if I restart Apache and try to login to dev (which was impossible before) then there is no problem here, but now it's impossible to login with the other subdomain new!
To sum up: I can't login to the two sudomains at the same time, no matter which (allowed) users I use.
The virtualhost for new subdomain is (the other one looks like this one changing paths):
<VirtualHost *:80>
ServerName new.mydomain.com
ServerAlias www.new.mydomain.com
ServerAdmin caumons#gmail.com
Alias /robots.txt /var/www/sites/master/EurekaStart.git/EurekaStart/robots.txt

SITE_PKG_PATH = os.path.abspath(os.path.dirname(__file__))

sys.path.append(SITE_ROOT_PATH)

Many thanks to#GrahamDumpleton :)
I've updated the apache config files and the way I was setting DJANGO_SETTINGS_MODULE. Now, the configuration regarding WSGI for Apache looks like:

How are you setting SESSION_COOKIE_DOMAIN?
https://docs.djangoproject.com/en/dev/ref/settings/#session-cookie-domain
and SESSION_COOKIE_NAME?
https://docs.djangoproject.com/en/dev/ref/settings/#session-cookie-name
Are they the same for both sites? The one for the domain should at least refer to the sub domain and not the main domain.
UPDATE 1
Instead of:
WSGIAuthUserScript /var/www/sites/master/EurekaStart.git/EurekaStart/wsgi.py
WSGIAuthGroupScript /var/www/sites/master/EurekaStart.git/EurekaStart/wsgi.py
use:
WSGIAuthUserScript /var/www/sites/master/EurekaStart.git/EurekaStart/wsgi.py application-group=new.mydomain.com
WSGIAuthGroupScript /var/www/sites/master/EurekaStart.git/EurekaStart/wsgi.py application-group=new.mydomain.com
The Python code run by WSGIAuthUserScript and WSGIAuthGroupScript always runs in the Apache child worker processes, never in daemon mode process where the main web application is.
More of a problem in your case is that by default the code runs in the main interpreter (application group) context. Because you have two sites, the code will not be separated.
By using application-group option on those directives, you can force the code for each separate site to run in different sub interpreters of the process they run in. Use a different value for application-group for the other site.
You also cannot use:
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "EurekaStart.settings")
you must use:
os.environ["DJANGO_SETTINGS_MODULE"] = "EurekaStart.settings"
Using dict.setdefault() causes problems when used by more than one site in the same process, even though in different sub interpreters. For more details see:

apache 500 internal error when updating from django 1.3 to 1.4

Originally when I installed Django 1.3 with wsgi on my ubuntu server I used the included setup.py file and so when I wanted to update followed the Remove any old versions of Django section of the install guide by renaming the "django" folder in my site-packages "django.old" and then installing the new version by using the the setup.py file for Django 1.4
After restarting my apache server I got a standard 500 Internal error. I checked the apache error log and discovered that ADMIN_MEDIA_PREFIX has been deprecated so following the Django 1.4 release notes I removed ADMIN_MEDIA_PREFIX from the settings file and moved the admin files into the static directory under a folder called "admin" as indicated.
I restarted my apache server again and received the same standard 500 error but this time when I tried running a tail on the apache error log no new errors registered.
Without any further error messages I am really stuck so any help will be appreciated.
