peewee.OperationalError - MySQL connection refused - mysql

Question

I'm using peewee for a Python ORM to a MySQL database and Flask to serve a web site from my local desktop running Ubuntu. I can connect to the database from the command line (mysql test -u user -p), but am getting a connection refused error when trying from Python. This code has worked on my previous Ubuntu PC, and I dumped the database from there, imported into the new PC and granted permissions, so I'm really not sure why it's giving me this.
Model.py:
from peewee import MySQLDatabase, Model, AutoField, CharField, IntegerField, \
ForeignKeyField, BooleanField, TextField, DateTimeField
from flask_security import UserMixin, RoleMixin
class BaseModel(Model):
"""
Base model for the model classes; prevents having to define Meta class with the
database for each Model class. Must call BaseModel._meta.database.init() before
connecting - should be able to just call once on BaseModel before
using derived model classes.
"""
class Meta:
database = MySQLDatabase(None) #init before calling connect()
#Additional code to define various tables
Trying to connect in Python command line:
import Model as mmm
db = mmm.BaseModel._meta.database
db.init('test', host = 'localhost', user = 'mike', passwd = password, port = 3306)
db.connect()
