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

Question

我正在尝试在 pythonanywhere 上部署一个 Django 项目，但出现错误-

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

我已经看到很多关于这个问题的问题，但没有答案能解决我的问题。可能是访问数据库时出现问题。

Database settings are-

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

在运行 show grants 命令上显示以下数据库（实际上我只需要其中一个数据库，但我无法删除多余的数据库）

mysql> show grants ;

+-------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for mutechrobotics@%                                                                                                               |
+-------------------------------------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'mutechrobotics'@'%' IDENTIFIED BY PASSWORD '*81F5E21E35407D884A6CD4A731AEBFB6AF209E1B' WITH MAX_USER_CONNECTIONS 3 |
| GRANT ALL PRIVILEGES ON `mutechrobotics$default`.* TO 'mutechrobotics'@'%'                                                                |
| GRANT ALL PRIVILEGES ON `mutechrobotics$mutechnew_db`.* TO 'mutechrobotics'@'%'                                                           |
| GRANT ALL PRIVILEGES ON `mutechrobotics$mutech_db`.* TO 'mutechrobotics'@'%'                                                              |
| GRANT ALL PRIVILEGES ON `mutechrobotics$mu_db`.* TO 'mutechrobotics'@'%'                                                                  |
+-------------------------------------------------------------------------------------------------------------------------------------------+
5 rows in set (0.00 sec)

my.cnf file is-
 [client]
password = "root"

当我尝试向用户提供所有特权时- "mutechrobotics" 然后我收到以下错误-

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


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

在尝试以 root 用户身份登录时出现错误 -

 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

谁能帮我解决这个问题。

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

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

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