This topic describes how to configure a SQL Server 2008 R2 database server to support web deployment and publishing.

The tasks described in this topic are common to every deployment scenario—it doesn’t matter whether your web servers are configured to use the IIS Web Deployment Tool (Web Deploy) Remote Agent Service, the Web Deploy Handler, or offline deployment or your application is running on a single web server or a server farm. The way you deploy the database may change according to security requirements and other considerations. For example, you might deploy the database with or without sample data, and you might deploy user role mappings or configure them manually after deployment. However, the way you configure the database server remains the same.

You don’t have to install any additional products or tools to configuring a database server to support web deployment. Assuming that your database server and your web server run on different machines, you simply need to:

This topic will show you how to perform each of these procedures. The tasks and walkthroughs in this topic assume that you’re starting with a default instance of SQL Server 2008 R2 running on Windows Server 2008 R2. Before you continue, ensure that:

The SQL Server instance only needs to include the Database Engine Services role, which is included automatically in any SQL Server installation. However, for ease of configuration and maintenance, we recommend that you include the Management Tools – Basic and Management Tools – Complete server roles.

Enable Remote Access to SQL Server

SQL Server uses TCP/IP to communicate with remote computers. If your database server and your web server are on different machines, you need to:

To enable SQL Server to communicate over TCP/IP, use SQL Server Configuration Manager to change the network configuration for your SQL Server instance.

To enable SQL Server to communicate using TCP/IP

  1. On the Start menu, point to All Programs, click Microsoft SQL Server 2008 R2, click Configuration Tools, and then click SQL Server Configuration Manager.

  2. In the tree view pane, expand SQL Server Network Configuration, and then click Protocols for MSSQLSERVER.

    [!NOTE] If you have installed multiple instances of SQL Server, you’ll see a Protocols for[instance name] item for each instance. You need to configure network settings on an instance-by-instance basis.

  3. In the details pane, right-click the TCP/IP row, and then click Enable.

  4. In the Warning dialog box, click OK.

  5. You need to restart the MSSQLSERVER service before your new network configuration will take effect. You can do that at a command prompt, from the Services console, or from SQL Server Management Studio. In this procedure, you’ll use SQL Server Management Studio.
  6. Close SQL Server Configuration Manager.
  7. On the Start menu, point to All Programs, click Microsoft SQL Server 2008 R2, and then click SQL Server Management Studio.

  8. In the Connect to Server dialog box, in the Server name box, type the name of the database server, and then click Connect.

  9. In the Object Explorer pane, right-click the parent server node (for example, TESTDB1), and then click Restart.

  10. In the Microsoft SQL Server Management Studio dialog box, click Yes.

  11. When the service has restarted, close SQL Server Management Studio.

To allow SQL Server traffic through a firewall, you first need to know which ports your SQL Server instance is using. This will depend on how the SQL Server instance was created and configured:

Assuming that you’re using a default instance of SQL Server, you need to configure your firewall to allow traffic.

Direction From Port To Port Port Type
Inbound Any 1433 TCP
Outbound 1433 Any TCP

[!NOTE] Technically, a client computer will use a randomly assigned TCP port between 1024 and 5000 to communicate with SQL Server, and you can restrict your firewall rules accordingly. For more information on SQL Server ports and firewalls, see TCP/IP port numbers required to communicate to SQL over a firewall and How to: Configure a Server to Listen on a Specific TCP Port (SQL Server Configuration Manager).

In most Windows Server environments, you’ll likely have to configure Windows Firewall on the database server. By default, Windows Firewall allows all outbound traffic unless a rule specifically prohibits it. To enable your web server to reach your database, you need to configure an inbound rule that allows TCP traffic on the port number that the SQL Server instance uses. If you’re using a default instance of SQL Server, you can use the next procedure to configure this rule.

To configure Windows Firewall to allow communication with a default SQL Server instance

  1. On the database server, on the Start menu, point to Administrative Tools, and then click Windows Firewall with Advanced Security.

  2. In the tree view pane, click Inbound Rules.

  3. In the Actions pane, under Inbound Rules, click New Rule.

  4. In the New Inbound Rule Wizard, on the Rule Type page, select Port, and then click Next.

  5. On the Protocol and Ports page, ensure that TCP is selected, and in the Specific local ports box, type 1433, and then click Next.

  6. On the Action page, leave Allow the connection selected and click Next.

  7. On the Profile page, leave Domain selected, clear the Private and Public check boxes, and then click Next.

  8. On the Name page, give the rule a suitably descriptive name (for example, SQL Server default instance – network access), and then click Finish.

Configure Logins and Database Permissions

When you deploy a web application to Internet Information Services (IIS), the application runs using the identity of the application pool. In a domain environment, application pool identities use the machine account of the server on which they run to access network resources. Machine accounts take the form [domain name]*[machine name]*$**—for example, **FABRIKAM\TESTWEB1$. To allow your web application to access a database across the network, you need to:

If your web application is running on a server farm, rather than a single server, you’ll need to repeat these procedures for every web server in the server farm.

[!NOTE] For more information on application pool identities and accessing network resources, see Application Pool Identities.

You can approach these tasks in various ways. To create the login, you can either:

A SQL Server login is a server-level object, rather than a database-level object, so it’s not dependent on the database you want to deploy. As such, you can create the login at any point, and the easiest approach is often to create the login manually on the database server before you start deploying databases. You can use the next procedure to create a login in SQL Server Management Studio.

To create a SQL Server login for the web server machine account

  1. On the database server, on the Start menu, point to All Programs, click Microsoft SQL Server 2008 R2, and then click SQL Server Management Studio.

  2. In the Connect to Server dialog box, in the Server name box, type the name of the database server, and then click Connect.

  3. In the Object Explorer pane, right-click Security, point to New, and then click Login.

  4. In the Login – New dialog box, in the Login name box, type the name of your web server machine account (for example, FABRIKAM1$).

  5. Click OK.

At this point, your database server is ready for Web Deploy publishing. However, any solutions you deploy won’t work until you map the machine account login to the required database roles. Mapping the login to database roles requires a lot more thought, as you can’t map roles until after you’ve deployed the database. To map the machine account login to the required database roles, you can either:

For more information on automating the creation of logins and database role mappings, see Deploying Database Role Memberships to Test Environments. Alternatively, you can use the next procedure to map the machine account login to the required database roles manually. Remember that you can’t perform this procedure until after you’ve deployed the database.

To map database roles to the web server machine account login

  1. Open SQL Server Management Studio as before.

  2. In the Object Explorer pane, expand the Security node, expand the Logins node, and then double-click the machine account login (for example, FABRIKAM1$).

  3. In the Login Properties dialog box, click User Mapping.
  4. In the Users mapped to this login table, select the name of your database (for example, ContactManager).

  5. In the Database role membership for: [database name] list, select the permissions required. In the case of the Contact Manager sample solution, you must select the db_datareader and db_datawriter roles.

  6. Click OK.

While manually mapping database roles is often more than adequate for test environments, it’s less desirable for automated or one-click deployments to staging or production environments. You can find more information on automating this kind of task using post-deployment scripts in Deploying Database Role Memberships to Test Environments.

[!NOTE] For more information on server projects and database projects, see Visual Studio 2010 SQL Server Database Projects.

Configure Permissions for the Deployment Account

If the account that you’ll use to run the deployment is not a SQL Server administrator, you’ll also need to create a login for this account. In order to create the database, the account must be a member of the dbcreator server role or have equivalent permissions.

[!NOTE] When you use Web Deploy or VSDBCMD to deploy a database, you can use Windows credentials or SQL Server credentials (if your SQL Server instance is configured to support mixed mode authentication). The next procedure assumes that you want to use Windows credentials, but there’s nothing stopping you from specifying a SQL Server user name and password in your connection string when you configure the deployment.

To set up permissions for the deployment account

  1. Open SQL Server Management Studio as before.
  2. In the Object Explorer pane, right-click Security, point to New, and then click Login.
  3. In the Login – New dialog box, in the Login name box, type the name of your deployment account (for example, **FABRIKAM*).
  4. In the Select a page pane, click Server Roles.

  5. Select dbcreator, and then click OK.

To support subsequent deployments, you’ll also need to add the deploying account to the db_owner role on the database after the first deployment. This is because on subsequent deployments you’re modifying the schema of an existing database, rather than creating a new database. As described in the previous section, you can’t add a user to a database role until you’ve created the database, for obvious reasons.

To map the deployment account login to the db_owner database role

  1. Open SQL Server Management Studio as before.
  2. In the Object Explorer window, expand the Security node, expand the Logins node, and then double-click the machine account login (for example, **FABRIKAM*).
  3. In the Login Properties dialog box, click User Mapping.
  4. In the Users mapped to this login table, select the name of your database (for example, ContactManager).

  5. In the Database role membership for: [database name] list, select the db_owner role.

  6. Click OK.

Conclusion

Your database server should now be ready to accept remote database deployments and to allow remote IIS web servers to access your databases. Before you attempt to deploy and use databases, you may want to check these key points:
