Django & MySQL - unable to open database file

Question

I'm setting up a new server in AWS (Ubuntu) to run Django, using WSGI, Python 2.7, Apache2 and MySQL. The initial page and the admin page are showing fine but I'm not able to login to the admin page after running syndcb. I have checked my database and the tables were built successfully, but when I try to login to the /admin/ page, I get:

OperationalError at /admin/ unable to open database file

/usr/lib/python2.7/dist-packages/django/db/backends/sqlite3/base.py in get_new_connection, line 346

I'm suspecting that is a cache somewhere pointing to sqlite3, which is wrong. There are no .pyc files in my app folder and here is the relevant part of my settings.py:

    DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'name',
        'USER': 'user',
        'PASSWORD': 'pw',
        'HOST': 'myhost',
        'PORT': '3306',
    }
}

Restarting Apache also won't work.

Exception Type: OperationalError at /admin/
Exception Value: unable to open database file

Answer 1

I vet that 'myhost' is not in your resolvconf file, so I'll put 127.0.0.1 or the ip you need to connect to your DB

If that's correct the next thing to look at, will be the apache config and BBDD permisions.
