The steps are as follows:
1. Insert the SQL Server installation media. From the root folder, double-click setup.exe. To install from a network share, locate the root folder on the share, and then double-click setup.exe. If the Microsoft SQL Server 2008 Setup dialog box appears, click OK to install the prerequisites, then click Cancel to exit SQL Server 2008 installation.
2. If the .NET Framework 3.5 SP1 installation dialog box appears, select the check box to accept the .NET Framework 3.5 SP1 License Agreement. Click Next. To exit SQL Server 2008 installation, click Cancel. When installation of .NET Framework 3.5 SP1 is complete, click Finish.
3. Windows Installer 4.5 is also required, and might be installed by the Installation Wizard. If you are prompted to restart your computer, restart it, and then restart SQL Server 2008 setup.exe.
4. When the prerequisites are installed, the Installation Wizard will run the SQL Server Installation Center. To create a new installation of SQL Server 2008, click New Installation or Add Features to an Existing Installation.
5. The System Configuration Checker will run a discovery operation on your computer. To continue, click OK. Setup log files are created for your installation.
6. On the Product Key page, select an option button to indicate whether you are installing a free edition of SQL Server, or a production version of the product that has a PID key.
7. On the License Terms page, read the license agreement, and then select the check box to accept the license terms and conditions.
8. The Installation Wizard will install SQL Server prerequisites if they are not already on the computer. These include the following:
– .NET Framework 3.5 SP1
– SQL Server Native Client
– SQL Server Setup Support Files
To install prerequisites, click Install.
9. The System Configuration Checker will verify the system state of your computer before Setup continues.
10. On the Feature Selection page, select the components for your installation. A description for each component group appears in the right pane after you select the feature name. You can select any combination of check boxes.
You can also specify a custom directory for shared components by using the field at the bottom of the Feature Selection page. To change the installation path for shared components, either update the path in the field at the bottom of the dialog box, or click Browse to move to an installation directory. The default installation path is C:\Program Files\Microsoft SQL Server\100\.
11. On the Instance Configuration page, specify whether to install a default instance or a named instance.
Instance ID — By default, the instance name is used as the Instance ID. This is used to identify installation directories and registry keys for your instance of SQL Server. This is the case for default instances and named instances. For a default instance, the instance name and instance ID would be MSSQLSERVER. To use a nondefault instance ID, select the Instance ID check box and provide a value.
Instance root directory — By default, the instance root directory is C:\Program Files\Microsoft SQL Server\100\. To specify a nondefault root directory, use the field provided, or click Browse to locate an installation folder.
All SQL Server service packs and upgrades will apply to every component of an instance of SQL Server.
Detected instances and features — The grid shows instances of SQL Server that are on the computer where Setup is running. If a default instance is already installed on the computer, you must install a named instance of SQL Server 2008.
12. The Disk Space Requirements page calculates the required disk space for the features that you specify. Then it compares the required space to the available disk space.
13. Work flow for the rest of this topic depends on the features that you have specified for your installation. You might not see all the pages, depending on your selections.
14. On the Server Configuration — Service Accounts page, specify login accounts for SQL Server services. The actual services that are configured on this page depend on the features that you selected to install.
You can assign the same login account to all SQL Server services, or you can configure each service account individually. You can also specify whether services start automatically, are started manually, or are disabled. Microsoft recommends that you configure service accounts individually to provide least privileges for each service, where SQL Server services are granted the minimum permissions they have to have to complete their tasks.
To specify the same logon account for all service accounts in this instance of SQL Server, provide credentials in the fields at the bottom of the page.
Security Note Do not use a blank password. Use a strong password.
When you are finished specifying login information for SQL Server services, click Next.
15. Use the Server Configuration — Collation tab to specify nondefault collations for the Database Engine and Analysis Services.
16. Use the Database Engine Configuration – Account Provisioning page to specify the following:
– Security Mode — select Windows Authentication or Mixed Mode Authentication for your instance of SQL Server. If you select Mixed Mode Authentication, you must provide a strong password for the built-in SQL Server system administrator account.
After a device establishes a successful connection to SQL Server, the security mechanism is the same for both Windows Authentication and Mixed Mode.
– SQL Server Administrators — You must specify at least one system administrator for the instance of SQL Server. To add the account under which SQL Server Setup is running, click Add Current User. To add or remove accounts from the list of system administrators, click Add or Remove, and then edit the list of users, groups, or computers that will have administrator privileges for the instance of SQL Server.
17. Use the Database Engine Configuration – Data Directories page to specify nondefault installation directories. To install to default directories, click Next.
18. Use the Database Engine Configuration – FILESTREAM page to enable FILESTREAM for your instance of SQL Server.
19. Use the Analysis Services Configuration — Account Provisioning page to specify users or accounts that will have administrator permissions for Analysis Services. You must specify at least one system administrator for Analysis Services. To add the account under which SQL Server Setup is running, click Add Current User. To add or remove accounts from the list of system administrators, click Add or Remove, and then edit the list of users, groups, or computers that will have administrator privileges for Analysis Services.
20. Use the Analysis Services Configuration — Data Directories page to specify nondefault installation directories. To install to default directories, click Next.
21. Use the Reporting Services Configuration page to specify the kind of Reporting Services installation to create. Options include the following:
– Native mode default configuration
– SharePoint mode default configuration
– Unconfigured Reporting Services installation
22. On the Error and Usage Reporting page, specify the information that you want to send to Microsoft that will help improve SQL Server. By default, options for error reporting and feature usage are enabled.
23. The System Configuration Checker will run one more set of rules to validate your computer configuration with the SQL Server features that you have specified.
24. The Ready to Install page shows a tree view of installation options that were specified during Setup. To continue, click Install.
25. During installation, the Installation Progress page provides status so that you can monitor installation progress as Setup continues.
26. After installation, the Complete page provides a link to the summary log file for the installation and other important notes. To complete the SQL Server installation process, click Close.
27. If you are instructed to restart the computer, do so now. It is important to read the message from the Installation Wizard when you have finished with Setup
