How can I fix the 'WSGI application not found' error in my Django project using Apache and mod_wsgi?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

Hi everyone,

I’m new to Django and have set up my first project, but when I deployed it with Apache and mod_wsgi, I encountered the following error:

Target WSGI script '/path/to/myproject/wsgi.py' does not contain WSGI application 'application'

This error is preventing my site from running. Below is an outline of my setup:

Project Structure:

myproject/
    ├── myproject/
    │   ├── __init__.py
    │   ├── settings.py
    │   ├── urls.py
    │   └── wsgi.py
    ├── manage.py
    └── app/
        ├── __init__.py
        ├── models.py
        ├── views.py
        └── ...

Apache Configuration:

APACHE
<VirtualHost *:80>
    ServerAdmin admin@example.com
    ServerName example.com
    ServerAlias www.example.com

    DocumentRoot /path/to/myproject
    WSGIScriptAlias / /path/to/myproject/myproject/wsgi.py

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

    Alias /static /path/to/myproject/static
    <Directory /path/to/myproject/static>
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

wsgi.py File:

PYTHON
import os
from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')
application = get_wsgi_application()

Troubleshooting Steps I’ve Taken:

Verified that the DJANGO_SETTINGS_MODULE is correctly set to myproject.settings
Ensured that wsgi.py is in the proper project directory
Checked file permissions for the project directory and files
Restarted Apache several times after applying configuration changes

Despite these efforts, the error persists. I believe there might be a misconfiguration or a missing step. I would appreciate any guidance on the following:

Is there an issue with my project directory structure?
Should there be any additional configuration in the wsgi.py file?
Have I overlooked any crucial steps in the Apache setup?

Thank you in advance for your help!

Best regards,
Emily

Fixing the mod_wsgi Configuration Issue

Based on your error message and configuration, there are a few potential issues that could be causing the "Target WSGI script does not contain WSGI application 'application'" error. Let's address them one by one:

Missing Python Path Configuration

Your Apache configuration is missing the WSGIPythonPath directive, which is crucial for mod_wsgi to find your Django project modules. You should add this to your configuration:

APACHE
WSGIPythonPath /path/to/myproject

This ensures that your project is in the Python path so that imports work correctly.

Virtual Environment Configuration

If you're using a virtual environment (which is recommended), you should also specify it:

APACHE
WSGIPythonHome /path/to/your/virtualenv

Updated Apache Configuration

Here's an updated version of your Apache configuration:

APACHE
<VirtualHost *:80>
    ServerAdmin admin@example.com
    ServerName example.com
    ServerAlias www.example.com

    DocumentRoot /path/to/myproject
    
    WSGIScriptAlias / /path/to/myproject/myproject/wsgi.py
    WSGIPythonPath /path/to/myproject
    WSGIPythonHome /path/to/your/virtualenv  # If using a virtualenv
    
    <Directory /path/to/myproject/myproject>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>

    Alias /static /path/to/myproject/static
    <Directory /path/to/myproject/static>
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

WSGI File Modification

Your wsgi.py file looks correct, but if you're running multiple Django sites in a single mod_wsgi process, you might need to change:

PYTHON
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')

to:

PYTHON
os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'

This ensures that the settings module is always set correctly, regardless of which site loads first.

File Permissions

Ensure that Apache can access and execute your WSGI file:

BASH
chmod 755 /path/to/myproject/myproject/wsgi.py

Also, make sure the parent directories have appropriate permissions:

BASH
chmod 755 /path/to/myproject
chmod 755 /path/to/myproject/myproject

Additional Troubleshooting Steps

Check Apache error logs for more detailed information:
```
BASH
tail -f /var/log/apache2/error.log
```
Verify that mod_wsgi is properly installed and enabled:
```
BASH
apache2ctl -M | grep wsgi
```

If you're using a virtual environment, ensure it has Django installed:

BASH
source /path/to/your/virtualenv/bin/activate
pip list | grep Django

Try using daemon mode to isolate your application:

APACHE
WSGIDaemonProcess myproject python-path=/path/to/myproject python-home=/path/to/your/virtualenv
WSGIProcessGroup myproject

Your project structure looks correct, and your wsgi.py file contains the necessary code. The issue is most likely related to the Apache configuration or permissions.
