拒绝访问Django:（1045，“用户'darth_vader'@'151.33.241.48（使用密码：是）”的访问被拒绝）

Question

我正在使用Django3.0和MySQL数据库作为我的web应用程序。 My settings.py代码是：

    DATABASES = {
  'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': 'thirdihrms',
    'USERNAME': 'admin',
    'PASSWORD': 'xxxxxxxx',
    'HOST': 'database-1.xxxxxxxxx.us-east-1.rds.amazonaws.com',
    'PORT': '3306',
   }
}

而不是连接到admin@151.33.241.48它正在连接到达斯·维德的用户名。 达斯·维德的名字是我的乌班图机器（本地开发环境）的家庭用户名

我看到了“达斯”_vader@Rushikesh-HP:~$“当我打开终端时

错误消息：

因此，是否有任何配置更改或设置更改，以便我可以运行我的应用程序

Answer 1

指定用户名的键是^{} [Django-doc]，而不是'USERNAME'。如文件规定：

USER

Default: '' (Empty string)

The username to use when connecting to the database. Not used with SQLite.

因此，您应该使用以下方法解决此问题：

DATABASES = {
  'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': 'thirdihrms',
    'USER': 'admin',  # noUSERNAME
    'PASSWORD': 'xxxxxxxx',
    'HOST': 'database-1.xxxxxxxxx.us-east-1.rds.amazonaws.com',
    'PORT': '3306',
   }
}
