SQL連接問題

我開發了一個使用Visual Studio 2012的asp.net網站內置模板的網站。SQL連接問題

它在ASP.NET開發服務器上運行良好。

當我上傳在IIS上的網站。當我嘗試登錄時遇到了下面提到的錯誤。

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 50 - Local Database Runtime error occurred. Cannot create an automatic instance. See the Windows Application event log for error details.

應該是什麼問題呢？

http://stackoverflow.com/questions/16256533/a-network-related-or-instance-specific-錯誤發生雖然建立一個連接 –

這個問題是非常普遍的，請檢查我的答案中的鏈接，並有幾個步驟要做，然後如果你得到錯誤，甚至在此之後，請讓我知道..！ –

您在連接字符串中爲您的數據庫使用localhost\SQLEXPRESS - 如果這是一個服務器，它需要替換爲活動服務器的數據庫實例的名稱。

這是你的配置部分

<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>

你實時的數據庫服務器不知道在哪裏localhost\SQLEXPRESS是。您需要更新這些connections strings以指向您的服務器正在使用的數據庫。

我想你還需要更新憑證。

你可以引導任何例子，因爲我只是初學者在軟件開發 – SPandya

事情是我不能甚至將mdf文件附加到管理工作室 – SPandya

@SPandya我試圖擴展，我不完全確定我還能做什麼添加 - 你可以聯繫你的託管服務提供商的支持團隊詢問有關連接和部署數據庫嗎？ – Liath

這一個

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>

我發現是因爲AppData文件夾中存在LocalDb數據庫發生錯誤 – SPandya

@SPandya您是否使用'.mdf'文件 –

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 50 - Local Database Runtime error occurred. Cannot create an automatic instance. See the Windows Application event log for error details.

有下完整的IIS運行時會產生問題的LocalDB的兩個屬性：

1.LocalDB needs user profile to be loaded

2.LocalDB instance is owned by a single user and private (by default)

很可能用戶配置文件未加載。如果LocalDB在IIS下執行，請確保爲當前用戶啓用配置文件加載。

谷歌搜索，發現這個偉大的職位：

Using LocalDB with Full IIS, Part 1: User Profile

當我在本地IIS部署一個ASP.NET MVC 4應用程序到一個新的網站，它創造了一個新的應用程序，我也有這個問題池。正如上面的文章描述一個必須啓用setProfileEnvironment =真正的應用程序池的文件中

C:\Windows\System32\inetsrv\config\applicationHost.config.

所以添加此

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

改變配置代碼後，不要忘記重新啓動應用程序池。

現在你應該閱讀的第二個職位，以應付LocalDB實例所有權：

Using LocalDB with Full IIS, Part 2: Instance Ownership
