Question

我正在尝试在pythonanywhere上部署一个django项目，但它给出了错误 -

(2003, "Can't connect to MySQL server on 'mysql.server' (111)")

我已经看到许多问题已经被问到这个问题，但没有答案解决了我的问题。可能存在访问数据库的previlleges问题。

数据库设置是 -

DATABASES = {    'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': 'mutechrobotics$mutech_db',
    'USER': 'mutechrobotics',
    'PASSWORD':'root',
    'HOST': 'mysql.server',
} }

在运行show grants命令后显示数据库（实际上我只需要一个数据库，但我无法删除额外的数据库）

mysql> show grants ;

+-------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for mutechrobotics@%                                                                                                               |

| GRANT ALL PRIVILEGES ON `mutechrobotics$mu_db`.* TO 'mutechrobotics'@'%'                                                                  |

5 rows in set (0.00 sec)

my.cnf文件是 -
 [client]
password = "root"

当我尝试将所有优先权交给用户 - “mutechrobotics”时，我收到以下错误 -

mysql> GRANT ALL PRIVILEGES ON *.* TO 'mutechrobotics'@'%'
 IDENTIFIED BY PASSWORD 'root';


ERROR 1045 (28000): Access denied for
     user 'mutechrobotics'@'%' (using password: YES)

尝试以root身份登录时，我收到错误 -

 mysql> mysql -u root -p ;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'mysql
 -u root -p' at line 1

有人请帮我解决这个问题。

不推荐使用mysql.server作为主机名。根据官方PythonAnywhere Django tutorial，您现在应该使用：

'HOST': 'username.mysql.pythonanywhere-services.com',

（2003年，“无法连接到MySQL服务器'mysql.server'（111）”）错误在pythonanywhere
