Question

我知道这个问题被问了很多次，但主题都没有对我有用。我已经在plesk控制面板Web服务器上发布了一个mvc网站，但我不断收到此错误：

CREATE DATABASE permission denied in database 'master'.

谁能告诉我发生了什么？我花了三天时间尝试了一切。这是我的连接字符串：

  <connectionStrings>
    <add name="application" connectionString="Data Source=.;Initial Catalog=bug.mdf;Integrated Security=false; User ID=admin;Password=###############" providerName="System.Data.SqlClient" />
  </connectionStrings>

错误：

Answer 1

错误完全是直截了当的。您的应用程序正在尝试创建数据库，并且与其连接的数据库用户没有该权限。至于为什么正在发生，很难用所提供的信息说出来。假设您实际上并未尝试在代码中显式创建数据库，这很可能是由于在您的上下文中设置了数据库初始化策略。默认情况下，如果数据库不存在，则尝试创建数据库。因此，您应该确保您要连接的实例确实具有您的应用程序尝试使用的数据库。

你可以也只是给DB用户创建数据库的权限，但这是一个非常糟糕的主意，安全性明智。您的Web应用程序的数据库用户应始终拥有最有限的权限集，基本上只有SELECT，INSERT，UPDATE和DELETE，甚至可能不是所有这些权限。在某些情况下，您可能也需要EXECUTE，但您可以逐个对象地授予它，而不是全局。

Answer 2

我认为您缺少数据库名称，即连接字符串中的初始目录

   <connectionStrings>
  <add name="application" connectionString="Data Source=.;Initial Catalog=NameOFDB; Integrated Security=false; User    ID=admin;Password=#slfsl$4554sll%" providerName="System.Data.SqlClient" />
  </connectionStrings>

在数据库＆＃39; master＆＃39;中拒绝CREATE DATABASE权限。发布到Web服务器时
