【问题描述】：
我正在 AWS (Ubuntu) 中设置一个新服务器来运行 Django，使用 WSGI、Python 2.7、Apache2 和 MySQL。
初始页面和管理页面显示正常，但运行syndcb 后我无法登录管理页面。我已经检查了我的数据库并且表构建成功，但是当我尝试登录到/admin/ 页面时，我得到：
/admin/ 处的操作错误 无法打开数据库文件
/usr/lib/python2.7/dist-packages/django/db/backends/sqlite3/base.py 在 get_new_connection，第 346 行
我怀疑这是一个指向 sqlite3 的缓存，这是错误的。我的 app 文件夹中没有 .pyc 文件，这是我的 settings.py 的相关部分：
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'name',
'USER': 'user',
'PASSWORD': 'pw',
'HOST': 'myhost',
'PORT': '3306',
}
}
重启 Apache 也不行。
