I'm trying to deploy my Django project in my server but I'm encountering some issues.
My environment :
Ubuntu 16.04 Server
Django 2.0
Python 3.5
Apache2 2.4
WSGI
Django configuration :
My Django project is located to : /var/www/html/DatasystemsCORE
I have wsgi.py file (/var/www/html/DatasystemsCORE/DatasystemsCORE) which looks like :
import os, sys
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "DatasystemsCORE.settings")
application = get_wsgi_application()
I have ALLOWED_HOST like this :
ALLOWED_HOSTS = ['localhost', '172.30.10.86', '[::1]']
Apache2 configuration :
In my apache2.conf file, I have :
WSGIScriptAlias / /var/www/html/DatasystemsCORE/DatasystemsCORE/wsgi.py
WSGIPythonPath /var/www/html/DatasystemsCORE
Alias /static/ /var/www/html/DatasystemsCORE/static/Theme/
<Directory /var/www/html/DatasystemsCORE/static/Theme/>
Require all granted
</Directory>
<Directory /var/www/html/DatasystemsCORE/DatasystemsCORE>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
And I have in sites-available/000-default.conf :
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/html/DatasystemsCORE
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
To my mind, all parameters seem to be right, but when I write : 172.30.10.86:80 in my browser, I get : 500 Internal Server Error
Traceback
This is the Traceback given by error.log in apache2 :

I tried lots of things according to multiple stackoverflow questions, but none answer up to now.
Did I miss something with wsgi or mod_wsgi ?
Edit
My latest apache conf file looks like :
<VirtualHost *:80>
ServerName DatasystemsCORE
DocumentRoot /var/www/html/DatasystemsCORE/DatasystemsCORE
WSGIPassAuthorization On
WSGIScriptAlias / /var/www/html/DatasystemsCORE/DatasystemsCORE/DatasystemsCORE.wsgi

</Directory>
<Directory /var/www/html/DatasystemsCORE/DatasystemsCORE>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
</VirtualHost>
SOLUTION
Servername in my apache2.conf file should refer to my server hostname and not my Django project !
HI can you try the below configuration:
import os
from django.core.wsgi import get_wsgi_application
import sys
sys.path.append('/var/www/html/DatasystemsCORE')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "DatasystemsCORE.settings")
application = get_wsgi_application()
Apache2 python wsgi module
sudo apt-get install python3-pip apache2 libapache2-mod-wsgi-py3
<VirtualHost *:80>
ServerName dev.example.com #your server name
ServerAlias dev.example.com #your server alias
DocumentRoot #your document root
WSGIProcessGroup dev.example.com
WSGIPassAuthorization On
WSGIDaemonProcess dev.example.com python-home=/home/robert/django/robertenv python-path=/var/www/html/DatasystemsCORE <Here should be your virtual env path >
WSGIScriptAlias / /var/www/html/DatasystemsCORE/DatasystemsCORE/wsgi.py
Alias /static/ /var/www/html/DatasystemsCORE/static/Theme/ #static directory
<Directory /var/www/html/DatasystemsCORE/static/Theme/>
Require all granted

Use above virtual host configuration

I have an init.py file inside itemcatalog directory, I did some search and found that maybe that python doesn't identify my itemcatalog as a package, what is the reason for this?
Python was installed globally but then I also tried to also install it inside a virtual environment.
This is the code for the virtual host:
<VirtualHost *:80>
ServerName 18.194.244.229
ServerAdmin admin#18.194.244.229
WSGIDaemonProcess itemcatalog python-path=/var/www/itemcatalog:/var/www/itemcatalog/venv/lib/python2.7/site-packages
WSGIProcessGroup itemcatalog
WSGIScriptAlias / /var/www/itemcatalog/itemcatalog.wsgi
<Directory /var/www/itemcatalog/>
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
And this is the file structure inside /var/www/itemcatalog/
Instead of:
WSGIDaemonProcess itemcatalog python-path=/var/www/itemcatalog:/var/www/itemcatalog/venv/lib/python2.7/site-packages
use:
WSGIDaemonProcess itemcatalog python-path=/var/www \
python-home=/var/www/itemcatalog/venv
The Python path must be the parent directory of the package, not the package directory itself.
Instead of using python-path to setup virtual environment, use python-home as explained in official documentation:
http://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html
