The information in this topic applies only to System Center
2012 Configuration Manager SP1. |
This topic provides the steps for how to configure Network Load
Balancing (NLB) in Configuration Manager with no service pack. NLB
can increase the reliability and performance of a network. You can
set up multiple WSUS servers that share a single SQL Server
failover cluster, and then configure a software update point to use
the NLB, but this configuration requires that you perform
additional steps during WSUS setup.
Note |
The maximum number of WSUS servers that can be configured as
part of a network load balancing cluster is four. |
Use the following sections to configure an active software
update point to use an NLB cluster:
- Prepare the network environment for network
load balanced software update point site systems.
- Install WSUS 3.0 (on each server that
will host the software update point site system role).
- Install the software update point site system
role (on each server that will be part of the software update point
network load balancing cluster).
- Configure the Windows Server network load
balancing cluster for installed software update site systems.
- Configure the active software update point
component for the Configuration Manager site as the software update
point network load balancing cluster.
Configure WSUS for Network
Load Balancing
Prepare the Network Environment for
NLB Software Update Point Site Systems
Use the following procedure to prepare the network
environment for the software update point to use an NLB
cluster.
To prepare the network environment for
NLB software update point site systems
-
Create or identify a domain user account to be used as
the Software Update Point Connection account.
-
Add the computer accounts of each site system that will
be configured as part of the software update point NLB cluster to
the local Administrators group on each server that will be part of
the NLB cluster.
Note |
The computer accounts for the cluster nodes must be able to
write to the WSUS database. If the local Administrators group is
removed from the SysAdmin role on the SQL server, the computer
accounts will not be able to write to the WSUS database, and the
software update point will fail to install until the computer
accounts are added to the SysAdmin role. |
-
Create a DFS share or a standard network shared folder
that is available to all of the WSUS servers that will be part of
the software update point NLB cluster to be used as the WSUS
resource content share. Each of the remote WSUS servers should be
given change permissions on the root of the shared folder (all
standard NTFS permissions except for Full Control). If the share is
created on one of the site systems that will be part of the NLB
cluster, the Network Access Account for the site system must have
change permissions on the root of the shared folder. The user
account used to run WSUS Setup must also have the same permissions
to the share.
-
Identify the computer running SQL Server to host
the WSUS database. The WSUS database can be installed on the same
SQL Server database server instance that hosts the site database or
a different SQL Server database server.
-
The WSUS 3.0 Administration console must be
installed on the primary site server to allow the site server and
remote Configuration Manager consoles to configure and synchronize
with WSUS.
-
If the Configuration Manager site is configured to
communicate by using SSL authentication, Web server signing
certificates must be configured on each of the software update
point site systems that will be configured as part of the NLB. For
more information about configuring Web server signing certificates
for network load balanced software update points, see PKI Certificate
Requirements for Configuration Manager.
Install WSUS 3.0 (on each server
that will host the software update point site system role)
Note |
The following procedure must be performed on each server that
will be part of the software update point NLB cluster. |
To install WSUS 3.0 to support the
Configuration Manager software update point site system role
-
On a server that will be part of the software update
point NLB cluster, create the following folder: <Program
Files directory>\Update Services.
-
Install WSUS 3.0 on each server that will be a
member of the software update point NLB cluster. For more
information about installing WSUS, see Install the WSUS 3.0 SP2 Server Software
Though the User Interface in the Windows Server Update Services
documentation library. During installation, consider the following
settings:
- On the Select Update Source page,
select the Store updates locally check box and enter the
path <Program Files directory>\Update
Services.
- On the Database Options page, do one
of the following.
- If you are running WSUS Setup on the server
hosting the WSUS SQL Server database, select Use an
existing database server on this computer select the instance
name to be used from the drop-down list.
- If you are running WSUS Setup on a computer
that will not host the WSUS SQL Server database, select Use
an existing database server on a remote computer and enter the
FQDN of the SQL Server that will host the WSUS database
followed by the instance name (if not using the default
instance).
Warning |
If another WSUS Server that will be part of the NLB cluster has
been configured to use the same SQL Server database server,
select Use existing database. |
-
Add the Software Update Point Connection Account to the
local WSUS Administrators group on the server.
-
On the SQL Server computer that hosts the WSUS
database, provide dbo_owner rights on the SUSDB database for
the Software Update Point Connection Account.
-
Configure Internet Information Services (IIS) to enable
content share access.
- Open the Internet Information Services (IIS) Manager
console.
- Expand <server name>, expand Sites, and
then expand the Site node for the WSUS Web site (either Default
Web Site or WSUS Administration).
- Configure the virtual directory Content to use the UNC share
name of the share created in step 3 of the To prepare the network environment for NLB
software update point site systems procedure in this topic.
- Configure the credentials used to connect to the virtual
directory with the user name and password of the Software Update
Point Connection Account created in step 1 of the To prepare the network environment for NLB
software update point site systems procedure in this topic.
-
Configure SSL authentication in Internet Information
Services (IIS).
Important |
This step is only required if the software update point will be
configured to communicate by using SSL. If you are not configuring
the software update point to use SSL, skip to step 6. |
- Open Internet Information Services (IIS) Manager.
- Expand Web Sites, and then expand the WSUS
administration Web site (either Default Web Site or WSUS
Administration).
- Configure the following virtual directories of the WSUS
administration Web site to use SSL:APIRemoting30,
ClientWebService, DSSAuthWebService,
ServerSyncWebService, and SimpleAuthWebService.
- Close Internet Information Services (IIS) Manager.
- Run the following command from <WSUS Installation
Folder>\Tools: WSUSUtil.exe configuressl
<Intranet FQDN of the software update point site system
node>.
-
Move the local content directory to the WSUS resource
content share created in step 3 of the To prepare the network environment for NLB
software update point site systems procedure in this topic.
Important |
This step must be followed for each of the front-end WSUS
servers that are not on the same server as the WSUS resource
content share |
- Open a command window and navigate to the WSUS tools directory
on the WSUS server: cd Program Files\Update
Services\Tools
- On the first WSUS server to be configured, at the command
prompt, type the following command:
wsusutil
movecontent<WSUSContentsharename><logfilename>
Where <WSUSContentsharename> is the name of the WSUS
content resource location share to which the content should be
moved, and logfilename is the name of the log file that will
be used to record the content move procedure.
- On the successive WSUS servers to be configured, at the command
prompt type the following command:
wsusutil
movecontent<WSUSContentsharename><logfilename>/skipcopy
Where <WSUSContentsharename> is the name of the WSUS
content resource location share to which the content should be
moved, and logfilename is the name of the log file that will
be used to record the content move procedure.
Note |
To verify that the content move was successful, review the log
file created during the procedure and use registry editor to review
the HKEY_LOCAL_MACHINE\Software\Microsoft\Update
Services\Server\Setup|ContentDir registry key to ensure that
the value has been changed to the WSUS content resource location
share name. |
