SQL连接问题

Question

I have developed a website using Visual Studio 2012's inbuilt template for asp.net website.

It worked fine with ASP.NET development server.

When I uploaded the website on IIS. I faced the error mentioned below when I tried to login.

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.

What should be the problem?

Answer 1

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.

There are two properties of LocalDB that cause problems when running under full IIS:

1.LocalDB needs user profile to be loaded

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

Most probably a user profile is not loaded. If LocalDB is executed under IIS, make sure that profile loading is enabled for the current user.

Searched Google and found this great post:

Using LocalDB with Full IIS, Part 1: User Profile

I too had this problem when I deployed an ASP.NET MVC 4 app to a new Website in my local IIS and it created a new application pool. As the post above describes one must enable setProfileEnvironment=true for the AppPool in the file

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

So add this

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

After changing the config code, don't forget to restart the app pool.

Now you should read this second post to deal with LocalDb Instance Ownership:

Using LocalDB with Full IIS, Part 2: Instance Ownership

Answer 2

You're using localhost\\SQLEXPRESS for your database in the connection strings - if this is a server it needs to be replaced with the name of the live server's DB instance.

Here's your config section

<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>

Your live database server doesn't know where localhost\\SQLEXPRESS is. You will need to update these connections strings to point to the database your server is using.

I assume you'll need to update the credentials too.

Answer 3

This one

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>
