Setting Up IIS 7.0 - Installing Application Servers

You can install an application server with or without Web server support by following these steps:

1.	Start Server Manager by clicking the Server Manager icon on the Quick Launch toolbar or by clicking Start, Administrative Tools, Server Manager.
2.	In Server Manager, select the Roles node in the left pane, and then, under Roles Summary, click Add Roles. This starts the Add Roles Wizard. If the wizard displays the Before You Begin page, read the Welcome page, and then click Next. You can avoid seeing the Welcome page the next time you start this wizard by selecting the Do Not Show Me This Page Again check box before clicking Next.
3.	On the Select Server Roles page, select the Application Server role. You'll then see the Add Features Required For Application Server dialog box. This dialog box lists the features that are required in order to install an application server. Click Add Required Features to close the dialog box and add the .NET Framework 3.0 components and the Windows Process Activation Service components to the application server installation.
4.	When you are deploying an application server with Web Server support, you can elect to accept the default common Web features or configure the exact features you'd like to use. If you have not installed Web Server (IIS) components previously and want to select the Web server (IIS) components for installation, select Web Server (IIS), and then click Next twice. Otherwise, just click Next twice to continue.
5.	You should now see the Select Role Services page. If not previously installed, select Web Server (IIS) Support to install the application server with Web server support in the standard default configuration. You'll then see a dialog box listing the additional required roles. After you review the required roles, click Add Required Role Services to close the dialog box. Note I recommend selecting Web Server (IIS) Support if the application server will host Web sites or Web services. This will ensure that Setup selects the required Web Common features by default, and this will be helpful later in the setup process.
6.	Select other role services to install as appropriate, and then click Next. If you select a role service with additional required features, you'll see a dialog box listing the additional required roles. After you review the required roles, click Add Required Role Services to close the dialog box.
7.	If you selected the WS-Atomic Transactions feature, you'll see the Choose A Certificate For SSL Encryption page next. You have the following options: Choose An Existing Certificate For SSL Encryption Select this option if you previously obtained a certificate from a certification authority (CA) and want to install it for use with the WS-AT site that Setup will configure on the server. If you've previously imported certificates using the Certificate snap-in or the Import Certificate Wizard, you'll see a list of available certificates, and you can click the certificate you want to use. Otherwise, click Import to start the Certificate Import Wizard, and then follow the prompts to import the certificate. Create A Self-Signed Certificate For SSL Encryption Select this option if you are using WS-Atomic transactions with a limited number of clients or for testing/development purposes and want to create and then automatically install a self-signing certificate for use with the WS-AT site that Setup will configure on the server. You will need to install the same certificate manually on all clients that need to be able to authenticate with the server. Choose A Certificate For SSL Encryption Later Select this option if you haven't obtained a certificate from a CA yet but plan to later. When you choose this option, IIS disables SSL on the WS-AT site until you import the certificate.
8.	If you selected Web Server (IIS) on the Select Server Roles page, as discussed in Step 5, click Next twice to display the Select Role Services page for Web server features. You can then select the Web server features to install. In most cases, you'll want to select additional features rather than trying to remove features. When selecting or clearing role services, keep the following in mind before you click Next to continue: If you select a role service with additional required features, you'll see a dialog box listing the additional required roles. After you review the required roles, click Add Required Role Services to accept the additions and close the dialog box. If you click Cancel instead, Setup clears the feature you previously selected. If you try to remove a role service that is required based on a previous selection, you'll see a warning prompt about dependent services that Setup must also remove. In most cases, you'll want to click Cancel to preserve the previous selection. If you click Remove Dependent Role Services, Setup will remove the previously selected dependent services, which could cause the Web server to not function as expected
9.	Click Next. On the Confirm Installation Selections page, click the Print, E-mail, Or Save This Information link to generate an installation report and display it in Windows Internet Explorer. You can then use standard Windows Internet Explorer features to print or save the report. After you've reviewed the installation options and saved them as necessary, click Install to begin the installation process.
10.	When Setup finishes installing the application server with the features you've selected, you'll see the Installation Results page. Review the installation details to ensure that all phases of the installation completed successfully. If any portion of the installation failed, note the reason for the failure, and then use these troubleshooting techniques: Click the Print, E-mail, Or Save The Installation Report link to create or update the installation report and display it in Windows Internet Explorer. Scroll down to the bottom of the installation report in Windows Internet Explorer, and then click Full Log (For Troubleshooting Only) to display the Server Manager log in Notepad. In Notepad, press Ctrl+F, type the current date in the appropriate format for your language settings, such as 2007-08-30, and then click Find Next. Notepad will then move through the log to the first Setup entry from the current date. Review the Server Manager entries for installation problems, and take corrective actions as appropriate.
