Не подключается Mysql

Пытаюсь поменять sqllite на mysql в settings.py

DATABASES = {
'default': {
    'ENGINE': 'mysql',
    'NAME': 'djangodb51',                    
    'USER': 'djangodb51',
    'PASSWORD': '*******',
    'HOST': 'localhost',   
    'PORT': '3306',                     
} 
}

Выдаёт

Попробовал на новой машине: система Freebsd 10, Python2.7, Django 1.7.0.

То же самое.
