Question

我在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我在运行syndcb后无法登录管理页面。我检查了我的数据库并且表格已成功构建，但当我尝试登录/admin/页面时，我得到：

   / admin /的OperationalError   无法打开数据库文件

/usr/lib/python2.7/dist-packages/django/db/backends/sqlite3/base.py in   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也无法工作。

更新追溯：

Answer 1

我审查了那个＆my;＆＃39; myhost＆＃39;不在您的resolvconf文件中，所以我将127.0.0.1或您需要连接到您的数据库的IP

如果这是正确的，那么接下来要看的是apache配置和BBDD permisions。
