SQL连接问题

标签： c# asp.net sql-server

我使用Visual Studio 2012的内置模板为asp.net网站开发了一个网站。

它适用于ASP.NET开发服务器。

当我在IIS上载网站时。我尝试登录时遇到了下面提到的错误。

  

建立与SQL Server的连接时发生与网络相关或特定于实例的错误。找不到服务器或   无法访问。验证实例名称是否正确   SQL Server配置为允许远程连接。 （提供者：SQL   网络接口，错误：50 - 发生本地数据库运行时错误。   无法创建自动实例。请参阅Windows应用程序事件   记录错误详情。

应该是什么问题？

3 个答案:

答案 0 :(得分：3)

  

发生与网络相关或特定于实例的错误   建立与SQL Server的连接。找不到服务器或   无法访问。验证实例名称是否正确   SQL Server配置为允许远程连接。 （提供者：SQL   网络接口，错误：50 - 发生本地数据库运行时错误。   无法创建自动实例。请参阅Windows应用程序事件   记录错误详情。

在完整IIS下运行时，LocalDB有两个属性会导致问题：

  

1.LocalDB需要加载用户个人资料

     

2.LocalDB实例由单个用户拥有，私有（默认情况下）

很可能未加载用户个人资料。如果在IIS下执行LocalDB，请确保为当前用户启用了配置文件加载。

搜索了Google并找到了这篇精彩帖子：

Using LocalDB with Full IIS, Part 1: User Profile

当我将ASP.NET MVC 4应用程序部署到本地IIS中的新网站时，我也遇到了这个问题，并且它创建了一个新的应用程序池。 如上面的帖子所述，必须为文件

中的AppPool启用setProfileEnvironment = true 
 C:\Windows\System32\inetsrv\config\applicationHost.config.

所以添加这个

<add name="MyAppPoolName" />
<processModel identityType="ApplicationPoolIdentity"
              loadUserProfile="true"
              setProfileEnvironment="true" />
</add>

更改配置代码后，请不要忘记重新启动应用程序池。

现在您应该阅读第二篇文章来处理LocalDb Instance Ownership：

Using LocalDB with Full IIS, Part 2: Instance Ownership

答案 1 :(得分：1)

您在连接字符串中使用localhost\SQLEXPRESS作为数据库 - 如果这是服务器，则需要将其替换为实时服务器的数据库实例的名称。

这是您的配置部分

<connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-TimeCard-20131218110938;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-TimeCard-20131218110938.mdf"
      providerName="System.Data.SqlClient" />
    <add name="TimeCardConnectionString" connectionString="Data Source=localhost\SQLEXPRESS;Initial Catalog=TimeCard;Integrated Security=SSPI"
      providerName="System.Data.SqlClient" />
    <add name="MCASConnectionString" connectionString="Data Source=localhost\SQLEXPRESS;Initial Catalog=MCAS;Integrated Security=True"
      providerName="System.Data.SqlClient" />
    <add name="TimeCardConnectionString2" connectionString="Data Source=localhost\SQLEXPRESS;Initial Catalog=TimeCard;Integrated Security=True"
      providerName="System.Data.SqlClient" />
  </connectionStrings>

您的实时数据库服务器不知道localhost\SQLEXPRESS的位置。您需要更新这些connections strings以指向您的服务器正在使用的数据库。

我假设您还需要更新凭据。

答案 2 :(得分：0)

这一个

connectionString="Data Source=.\SQLEXPRESS;


    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-TimeCard-20131218110938;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-TimeCard-20131218110938.mdf"
      providerName="System.Data.SqlClient" />
    <add name="TimeCardConnectionString" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=TimeCard;Integrated Security=SSPI"
      providerName="System.Data.SqlClient" />
    <add name="MCASConnectionString" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=MCAS;Integrated Security=True"
      providerName="System.Data.SqlClient" />
    <add name="TimeCardConnectionString2" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=TimeCard;Integrated Security=True"
      providerName="System.Data.SqlClient" />
  </connectionStrings>
