Answer 1

You could create the conexión using

sqlalchemy.create_engine(
        mysql_str = sqlalchemy.engine.url.URL(
            drivername='mysql+pymysql',
            username="db_user",
            password="db_pass",
            database=db_name,
            query={
                'unix_socket': '/usr/local/mysql5/mysqld.sock'
            }
        )
)

Answer 2

You'll have to dig up the exact syntax, but for MySQL I think they use a unix_socket query opt. Something like:

mysql:///dbname?unix_socket=/opt/mysql/mysql.sock'

Should be your connect URI for SQLAlchemy.

Answer 3

Yes! Sean was right

app.config['SQLALCHEMY_DATABASE_URI'] = ''mysql://dayenu:secret.word@localhost/dayenu?unix_socket=/usr/local/mysql5/mysqld.sock
db = SQLAlchemy(app)

works fine! I think this parameter is used by pyodbc, which is what SQLAlchemy uses to talk to mysql, but I couldn't find this parameter anywhere in the pyodbc documentation.
