Django 和 MySQL 的数据库访问问题

我已经mod_wsgi启动并运行了 Apache，现在正尝试将 Django 引入 MySQL。

我创建了一个名为“django”的数据库和一个“django”用户；并且我已在 django 上将所有权限授予 django：

grant ALL on django.* to 'django'@'localhost';

Django 的 settings.py 已经配置了 MySQL 的设置：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'django': '',                      # Or path to database file if using sqlite3.
        'django': '',                      # Not used with sqlite3.
        '<a password>': '',                  # Not used with sqlite3.
        '': '',                      # Set to empty string for localhost. Not used with sqlite3.
        '': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

但是当我尝试运行 syncdb( python manage.py syncdb) 时我得到：

raceback (most recent call last):
  File "manage.py", line 14, in <module>
    execute_manager(settings)
  File "/usr/lib/python2.6/site-packages/django/core/management/__init__.py", line 438, in execute_manager
    utility.execute()
  File "/usr/lib/python2.6/site-packages/django/core/management/__init__.py", line 379, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "/usr/lib/python2.6/site-packages/django/core/management/base.py", line 191, in run_from_argv
    self.execute(*args, **options.__dict__)
  File "/usr/lib/python2.6/site-packages/django/core/management/base.py", line 219, in execute
    self.validate()
  File "/usr/lib/python2.6/site-packages/django/core/management/base.py", line 249, in validate
    num_errors = get_validation_errors(s, app)
  File "/usr/lib/python2.6/site-packages/django/core/management/validation.py", line 102, in get_validation_errors
    connection.validation.validate_field(e, opts, f)
  File "/usr/lib/python2.6/site-packages/django/db/backends/mysql/validation.py", line 14, in validate_field
    db_version = self.connection.get_server_version()
  File "/usr/lib/python2.6/site-packages/django/db/backends/mysql/base.py", line 338, in get_server_version
    self.cursor()
  File "/usr/lib/python2.6/site-packages/django/db/backends/__init__.py", line 250, in cursor
    cursor = self.make_debug_cursor(self._cursor())
  File "/usr/lib/python2.6/site-packages/django/db/backends/mysql/base.py", line 322, in _cursor
    self.connection = Database.connect(**kwargs)
  File "/usr/lib/python2.6/site-packages/MySQLdb/__init__.py", line 81, in Connect
    return Connection(*args, **kwargs)
  File "/usr/lib/python2.6/site-packages/MySQLdb/connections.py", line 187, in __init__
    super(Connection, self).__init__(*args, **kwargs2)
_mysql_exceptions.OperationalError: (1045, "Access denied for user 'ec2-user'@'localhost' (using password: NO)")

最后一行让我很困惑。我不确定它为什么尝试以ec2-user而不是进行连接Django。

答案1

您知道，我不确定为什么它会默认为 ec2-user（除非它恰好是运行 Django 的进程的所有者），但该配置文件远非标准。我相信您想要：

default': {
        'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME':'django',                      # Or path to database file if using sqlite3.
        'USER':'django',                      # Not used with sqlite3.
        'PASSWORD':'<a password>',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }

看起来最初您不是替换“NAME”值，而是替换了“NAME”键（对于字典中的所有其他键也一样）。
