错误是没有建立mysql的权限，这个课程中有介绍，首先：

1、看看 settings中的配置，如下：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'imoocc',
        'USER': 'imoocc',
        'PASSWORD': 'imoocccom',
        'HOST': '127.0.0.1',
        'PORT': '',
        'OPTIONS': {},
        'init_command': 'SET storage_engine=INNODB,'
                        'SESSION TRANSACTION ISOLATION LEVEL READ COMMITTED, autocommit=1, names "utf8";',
    }
}

2、用root用户登陆mysql

mysql -uroot -p

先创建imoocc库，如下：

mysql> create database imoocc

登陆后建立imoocc用户权限，如下：

mysql> grant all on imoocc.* to imoocc@'%' identified by 'imoocccom';

Query OK, 0 rows affected (0.00 sec)

mysql> grant all on imoocc.* to imoocc@'localhost' identified by 'imoocccom';

Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;                                                   

Query OK, 0 rows affected (0.00 sec)

3、测试

用mysql命令测试，如下：

mysql -uimoocc -p'imoocccom' -h mysql服务的IP地址
