Django 500 Internal Server Error - ImproperlyConfigured: Error loading MySQLdb module:

Im new to using MySQL in general and as a database for Django. I have followed a number of different tutorials and the documentation but keep getting a 500 Internal Server Error when i deploy to my production server. It works fine on my development machine.

What am I missing? is there a setting I should change or a step i missed?

Thanks

The Error logs

My Setup

My settings.py

DATABASES = {
    'default': { 
        'ENGINE': 'django.db.backends.mysql', 
        'NAME': 'django_db',                                       
        'USER': 'root',
        'PASSWORD': 'my_password',
        'HOST': '127.0.0.1',
        'PORT': '', 
    }
}

I have created the database on my production environment

CREATE DATABASE django_db;
Query OK, 1 row affected (0.01 sec) 
mysql>

I then ran syncdb

(bias_experiment)Macintosh-2:src user$ python manage.py syncdb
Creating tables ...
Creating table django_admin_log
....

In the interest of helping others who may come to this post with the same error:

I was receiving the same error, but my MySQL-python version was the same as the expected: 1.2.5. The problem was that I had the MySQLdb folder symlinked into my project's root folder. By moving the symlinked folder into the folder that holds my Django settings I was able to fix the issue.

This line:

ImproperlyConfigured: Error loading MySQLdb module: this is MySQLdb version (1, 2, 5, 'final', 1), but _mysql is version (1, 2, 3, 'final', 0)

indicates you might have a version mismatch between MysqlDB and MySQL. Sounds like looking in to it and reinstalling your dependent libraries resolved the issue.

To describe the issue in further detail:

In this case apt-get was installing MySQL-python==1.2.3. The latest version is MySQL-python==1.2.5. However apt-get was not finding it, so completely removing MySQL-python==1.2.3 using:

sudo apt-get remove --purge python-mysqldb

and then reinstall via pip 

sudo pip install mysql-python

(Note the package names are slightly different)
