System Center Service Manager 2016 step by step installation

Server Names & Roles

SQL-01: SQL Database Services, SQL Analysis Services, SQL Reporting Services.
SM-01:  Management Server
DW-01:  Data Warehouse Management Server
SMP-01: Self Service Portal

SQL 2016 Enterprise with SP2 will be the base standard for all SQL Database, Analysis, and Reporting services.

Service Accounts

In AD, create the following accounts and groups, according to your naming convention:

DOMAIN\Srv-SMSrv             Service Manager Server Service Account
DOMAIN\Srv-SMWf             Service Manager Mail Enabled Workflow Account
DOMAIN\Srv-SMRep           Service Manager Reporting and Analysis Account
DOMAIN\Srv-SQL                 SQL Service Account
DOMAIN\Service Manager Admins   SM Administrators security group

Add the three SM service accounts, and the domain users who will be Service Manager Admins to the “Service Manager Admins” Group.  Also add the “Service Manager Admins” domain group to the Local Administrators group on each server.

Obviously change the naming conventions to meet your organisational requirements.


Prerequisites

Service Manager setup requires some prerequisites.  Before starting with Service Manger 2016 installation, make sure that these are installed. The following prerequisites are required to successfully install Service Manager 2016:


Installation

Now you start the Service Manager installation.  Click Service Manager management server under the Install section:

Enter your product registration details and product key if applicable:

Select the default installation location unless you wish to change it:

If you installed all the necessary prerequisites, you should see a similar screen to this, if not ensure you carry out the required actions install any missing items:

Next you need to specify SQL Server and Instance name where Service Manager will create the main database. Note i am installing the databases on a stand alone SQL server in this series of articles and Service Manager 2016 also supports SQL AlwaysOn installations:

Note: The Service Manager Sizing Helper Tool is provided as a downloadable utility, the Service Manager Sizing Helper tool can help to establish the number of Server Manager servers you need and assist with sizing your databases.  The tool is a graphical utility that is part of the Service Manager Job Aids documentation set. You can download the Service Manager Sizing Helper Tool from http://go.microsoft.com/fwlink/?LinkId=186291.

Note that if you are using the default collation (SQL_Latin1_General_CP1_CI_AS), you will receive the following warning. It basically warns you that support for multiple languages in Service Manager is not possible when using the default collation:image

Now define the name of the new Service Manager management group. They must be unique and not the same as the DW server or Operations Manager management groups!  Also specify the  administrators group you created earlier:

image

Enter the credentials of the Service Manager Service Account (In this case its Srv-SMSrv). This will be the Operational System Account and becomes the logon account for the “System Center Data Access Service” and “System Center Management Configuration service”.

This account should already be a member of the Local Admin group on the SM server as you should of added the Service Manager Admins group to the servers earlier in this article.

image

Now enter the credentials of the Service Manager Workflow Account (In this case Srv-SMWf). This account is used for all the workflows and is made a member of the Service Manager Workflows user role.

By default Microsoft now collects diag and usage data.  This can be turned off later but click next to continue the installation:

Click Install to start the installation:

After 15 minutes or so the installation should complete, click close and the Encryption Backup or Restore wizard should start:

image

You MUST backup the encryption key as it is used to encrypt sensitive information in Service Manager and is required should you ever need to perform a management server restore.  Save it somewhere safe, NOT on the Service Management Servers! Winking smile

SPN Records

One configuration step often missed is setting the SPNs (Service Principle Names) for Service Manager.  Note, the account completing the install doesn’t has permission to create the SPN as its not a Domain Admin!

If the SPNs aren’t registered you will notice an event log warning is registered. The event ID is 26371 “The System Center Data Access Service failed to register an SPN”.

To check the SPNs registered to your service account you can use the SETSPN command:

SETSPN –l DOMAIN\SMServiceAccount

Where domain is your domain and SMServiceAccount is the Service Manager Server Service Account.

image

You can see above there are no SPN’s registered therefore in order to register them run the following commands:

setspn –A SMServiceAccount/SMSERVERNAME DOMAIN\SMServiceAccount
setspn –A SMServiceAccount/SMSERVERNAME.fqdn.name DOMAIN\SMServiceAccount

For Example:

setspn –A Srv-SMSrv/IC-OR-SM-01 INDICIUM\Srv-SMSrv
setspn –A Srv-SMSrv/IC-OR-SM-01.indicium.cloud INDICIUM\Srv-SMSrv

Now when you run:

SETSPN –l DOMAIN\SMServiceAccount

image

You can see the SPN has been registered.
