With the release of SQL Server 2005 Express Edition and the SQL Server Management
Studio Express, Microsoft has entered the small, free database market with a splash
trumping even their own Microsoft SQL Desktop Edition. SQL Server Management Studio
Express — a full-featured management tool comparable to the legacy SQL Server Enterprise
Manager — makes this entry-level database software usable and formidable for running
small businesses, small Web sites, and more.

To get SQL Server 2005 Express Edition install on your server,
follow these steps.

Software prerequisites

.NET Framework 2.0 & MSXML 6

Other requirements

Server joined to your Active Directory domain.

I highly recommend that you don’t use one of your existing servers
for this purpose. If you don’t have any reasonable spare hardware, consider using
VMware Server or Virtual
Server 2005 R2
and creating a virtual machine. Both products are free, and great
for creating test beds. SQL Server 2005 requires the .NET Framework 2.0, which breaks
some applications, so keeping the database separate is a good idea.

Step 3: Install database software prerequisites

I mentioned above that there are a number of software prerequisites
for SQL Server 2005 Express Edition. Before you can install the database software,
you need to take the necessary steps to get these items installed.

Install the following items in order.

Internet Information Server 5 or higher

If your Windows server does not have IIS installed, go to Start
| Control Panel | Add or Remove Programs | Add/Remove Windows Components.

.NET Framework 2.0

Download the .NET Framework 2.0 (x86) from here.
After downloading, execute dotnetfx.exe
and follow the instructions to complete the installation. I’d show a screenshot,
but there’s really not a whole lot to see!

MSXML6

Download MSXML6 from here.
Execute msxml6.msi. This is a quick installation.

Step 4: Create a SQL Server service account

From a security perspective, it’s best to run SQL Server as a
normal everyday user. When possible, don’t use the built-in service accounts on
your SQL Server as this practice does not limit your server’s attack surface as
much as using an unprivileged user account.

Create a domain account named “SQLExpressUser” for
this purpose. If you’re joined to a domain — which you should be — use Active
Directory Users and Computers. If you’re just testing locally, use Computer Management
to add the account. Make sure to also assign a strong password to the account.

I have also configured this user account so that the password
does not expire. In addition, anyone logging in as this user — no one should
be doing that though — will not be able to change the password.

Step 5: Install SQL Server 2005 Express Edition

For this article, I am installing SQL Server 2005 Express Edition
with Advanced Services SP1. The name of the downloaded file is SQLEXPR_ADV.EXE. Double-click this file to
start the product installation. The contents of the file are extracted and the installation
begins.

After you start the installation, you have to agree to the typical
End User License Agreement after which you’re presented with a screen that shows
you what prerequisites you need to get the express edition on your system. The installer
will handle the installation of these prerequisites for you. Click the Install button
to install these items. Once the items are installed, click the Next button.

Figure A

The new Native Client and the Setup Support Files need to be installed.

Once the prerequisites are in place the SQL Server installation
wizard will start. The first screen you’re shown provides you with a list of items
that may or may not give you trouble if you continue the
installation. In Figure B below, you
can see that my test system has a warning regarding the minimum hardware requirements.
I am installing SQL Server 2005 Express Edition into a VMware Server-based virtual
machine and the installer doesn’t seem to like that I have allocated only 768MB
RAM to the virtual machine when it really wants 1GB. However, this warning is not
a show-stopper, so I’ll continue. Note that the installer provides you with a complete
status report to make it easy for you to determine what needs to be done. Click
Next to continue.

Figure B

If you have any serious problems, correct them before you continue.

After that, you have to provide your name and, optionally, your
company’s name. I have also unchecked the box marked “Hide advanced configuration
options” so you can get a look at these options during the installation.

Figure C

Provide registration details for your server installation.

Next, you get to choose which features you want to install. Even
though the Express Edition is free, it includes many of the features found in the
Standard and Enterprise editions. I’ve decided to install everything except replication.
Note that I’ve opted also to install the Management Studio Express. This is an outstanding
utility provided by Microsoft and it replaces Query Analyzer and Enterprise Manager.
I highly recommend you install this tool. I’m installing into the default location,
C:\Program Files\Microsoft SQL Server.
If you want to install to a different location, click the Browse button to choose
this new location.

Figure D

Decide which features you want to install. The only one you absolutely need
is the Database Services option, but the others are very useful.

Instances were introduced in SQL Server 2000 and provide a way
for you to more seamlessly serve multiple databases from a single SQL Server. SQL
Server 2005 Express Edition supports up to 16 named instances while the Enterprise
Edition supports up to 50. For my installation, I’m installing SQL Server 2005 Express
Edition as the default database instance on my server.

Figure E

Choose your instance.

Service accounts are used in order to better protect your SQL
Server — and the rest of your network — in the event of a security breach. If
you run your SQL Server under an administrative account, you run the risk of additional
damage should your server be compromised. Therefore, run SQL Server 2005 Express
Edition under a user account with few, if any, rights.

Figure F

Use the account you created before as the service account for SQL Server 2005.

SQL Server can authenticate users in two ways: (1) directly against
Active Directory (Windows Authentication Mode); (2) against its own database (Mixed
Mode, since Windows Authentication is also supported). From a security perspective,
Windows Authentication mode is highly preferred. First off, you have only a single
user database — Active Directory — to worry about.

However, Windows Authentication Mode is not always appropriate.
For example, I’ve had better luck scripting against a Mixed Mode SQL Server versus
a Windows Authentication Mode SQL Server. If you choose Mixed Mode (which you should)
you will also need to provide a password for the SQL Server ‘sa‘ user. Make sure that you assign a strong
password if you take this route.

Figure G

Choose the mode under which you want to authenticate SQL Server users.

The next step of the installation involves selecting a collation
method, which defines the way that your SQL Server will sort data. If you need to
maintain backward compatibility with older versions of SQL Server, you should choose
SQL Collations. If, however, you do not need to worry about backward compatibility,
you should choose the Latin1_General collation method, unless, of course, you’re
using a different language.

Figure H

Choose your collation method.

SQL Server 2005 Express provides a new feature: The ability to
run sub-instances of the product under a normal user account. User instances are
useful in situations in which users are logged into Windows under a least-privileged
user account. Using user instances, the user can still have SQL system administrator
privileges to their SQL “sandbox”, but the rest of the system is protected
since the user’s primary account does not have rights to make global changes. Databases
housed under user instances support only a single connection and higher-end features
such as replication are not supported.

If you want to support user instances in your installation, make
sure the checkbox next to “Enable User Instances” is selected.

Figure I

Decide whether you want to enable support for user instances.

Introduced as an add-on for SQL Server 2000, an enhanced version
of Reporting Services is included with SQL Server 2005. For your small SQL Server
2005 Express Edition installation, I recommend that you install this feature, but
don’t worry about customizing the configuration. The default configuration places
the tool at http://{your server name}/ReportServer.
The Report Manager tool is placed at http://{your
server name}/Reports
.

If you decide to use SQL Server 2005 and Reporting Services in
a production environment, make sure to obtain an SSL certificate for use with the
Reporting Services site, which is housed in IIS. I’ll provide another “How
Do I” article that explains how to install a certificate in IIS.

Figure J

Reporting Services is a welcome addition to SQL Server.

Microsoft has included an error reporting tool in other applications
for quite some time. This feature is now optionally included in SQL Server 2005
Express. Further, Microsoft wants you to send them anonymous usage data about your
installation. Neither option is enabled by default. Personally, I like the error
reporting service and the only way it will improve is by adding data. I don’t like
sending usage data, however. While it’s supposedly confidential, it doesn’t directly
benefit my installation.

Figure K

Decide what information you want to send to Microsoft.

These are all of your options for SQL Server 2005 Express Edition.
Continue on to install the product using these selections.

Figure L

The installation’s progress.

In some cases, your installation may fail with errors reported
for the SQL Native Client and the SQL Server Database Services. In addition, the
Workstation Components selection may indicate a failure. If this happens to you,
it may be because you formerly had a conflicting SQL Server service on the machine
and the Native Client previously installed is creating a problem. If this is the
case for you, follow these steps:

  1. Change to the directory in which you saved the downloaded
    SQL Server Express 2005 installer.
  2. Extract the contents of the installer to a new directory:
    SQLEXPR_ADV.EXE /x:c:\sqltmp.
    If you are using the download that does not contains the advanced services,
    this command is SQLEXPR.EXE /x:c:\sqltmp instead.
  3. Change to C:\sqltmp\setup.
  4. Execute “sqlncli.msi
  5. Choose the “Uninstall
    option.
  6. Reboot your server.
  7. Run the SQL Server Express 2005 installer again. It should
    be successful this time around.

Installed and ready

At this point, SQL Server 2005 Express Edition is installed and
can be managed using the SQL Server Management Studio Express tool that was installed
along with the database server. To access this tool go to Start | All Programs |
Microsoft SQL Server 2005 | SQL Server Management Studio Express.

In my next article, I will show you how to manage your new database
installation using the Surface Area Configuration tool and the Management Studio
Express.
