500 内部服务器错误 mod_wsgi apache "importerror: No Module named 'django'

Question

Issues running django and apache2/mod_wsgi. I keep getting 500 Internal Server Error. I have tried many combinations of fixes to which none have worked. Any help is greatly appreciated. This is my setup:

Ubuntu 16.04
django 1.10.5
apache 2.4.18
python 3.4(virtualenv)
libapache2-mod-wsgi-py3 

My folder structure is:

/home/user/site/venv (virtualenv folder)
    bin
    include
    lib

/home/user/site/mysite
    |- manage.py
    static
    mysite
        |__init__.py
        |settings.py
        |urls.py
        |wsgi.py

site.conf

<VirtualHost *:80>
WSGIDaemonProcess myproject python-home=/home/user/site/venv python-path=/home/user/site/mysite
WSGIProcessGroup myproject
WSGIScriptAlias / /home/user/site/mysite/mysite/wsgi.py

        Alias /static /home/user/site/mysite/static
        <Directory /home/user/site/mysite/static>
            Require all granted
        </Directory>

        <Directory /home/user/site/mysite/mysite>
            <Files wsgi.py>
                Require all granted
            </Files>
        </Directory>


</VirtualHost>

wsgi.py

import os

from django.core.wsgi import get_wsgi_application

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

application = get_wsgi_application()

apache2/error.log

I have given the permissions to the folders below:

sudo chown -R www-data:www-data /home/user/site/venv
sudo chown -R www-data:www-data /home/user/site/mysite

Any help or criticism I would love thank you in advance.

Answer 1

So after some intense head bashing against the wall. It turns out I needed to compile my own mod_wsgi for the version of python I was using. I was using the standard repo for ubuntu libapache2-mod-wsgi-py3 which is compiled to use with python3.5.2 as it shows in my error.log.

I went here for the most up to date version : mod_wsgi_releases

be sure to use the command below when installing mod_wsgi

.configure --with-python=/your/virtualenv/bin/python(your python_verion here)

Answer 2

Try using something like this. Just to confirm, is myproject the user group ?

WSGISocketPrefix /var/run/wsgi
WSGIPythonPath /home/user/site/venv/lib/python2.7/site-packages
WSGIDaemonProcess ec2-user processes=1
WSGIProcessGroup ec2-user
WSGIScriptAlias / /home/user/site/mysite/mysite/wsgi.py

Answer 3

try which django-admin in your virtual env. If this is different location than the location you desire it to be to work with, install django in your virtual env. Or try pip freeze > requirements.txt in your virtual env to see django is actually there.

Answer 4

有同样的问题，我通过卸载 gunicorn 并在我的项目中通过虚拟环境登录时重新安装来修复它
