在Anaconda内部的Python上使用mod_wsgi配置Django时出错：“ImportError：没有名为django.core.wsgi的模块”

Question

I'm having few problems running django+apache2 on ubuntu. Django 1.7, Apache2.4.7

I'm running anaconda stack with 3.4 as main + another environment on python 2

I was trying to set up simple test site and received internal error 500, with below error messages in error log of Apache:

wsgi.py:

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

its running ok with

python manage.py runserver

So the issue here is (I think) mod-wsgi wasn't configured on correct python, as default python is ("mod_wsgi/3.4 Python/2.7.6 configured") and django is installed on anaconda 2.7.9 one.

If my guess is good (please let me know what other info would we need for soultion) My question is: how do I recompile mod-wsgi so its linked against 2.7.9 environment from anaconda? Another question would be, can I leave it as it is and just add some directive to link to anaconda libraries? Which folder would be that and where do I put WSGIPythonHome directive then?

Thank you for having a look

Answer 1

Had similar problem, answer was in virtual host file:

WSGIDaemonProcess mysite python-path=/path/to/mysite:/path/to/anaconda3/envs/python2/lib/python2.7/site-packages/
WSGIProcessGroup mysite
WSGIScriptAlias / /path/to/mysite/mysite/wsgi.py

ServerName www.mysite.com
ServerAlias mysite.com
ServerAdmin webmaster@mysite.com

<Directory /path/to/mysite/mysite>
<Files wsgi.py>
Require all granted
</Files>
</Directory>

ErrorLog /path/to/web/test/error.log

Answer 2

Check this setting in httpd.conf of your Apache:
In your <VirtualHost x:y> section, make sure that value of python-path in WSGIDaemonProcess is including the Python site-packages directory in your Anaconda installation .
Othwerwise, mod_wsgi may not find Django that you've installed for Python inside Anaconda .

For example, if you've installed Anaconda to: /opt/anaconda2
Python site-packages directory may be: /opt/anaconda2/lib/python2.7/site-packages
Therefore, change WSGIDaemonProcess as:
WSGIDaemonProcess YOUR_PROJECT_NAME python-path=/opt/anaconda2/lib/python2.7/site-packages:YOUR_PROJECT_DIRECTORY ......
(Separate each path by colon : )

Note:
1. The version number within the path may change according to your tools' version. Please find similar path and try it.
2. This issue may happen on every Linux distribution (not only Ubuntu), even Windows.
