Registering SUSE Linux Enterprise Server with Expanded Support Clients
This section contains information about registering traditional and Salt clients running SUSE Linux Enterprise Server with Expanded Support (Expanded Support) operating systems.
Expanded Support clients are based on Red Hat Enterprise Linux or CentOS.
They are sometimes also called SLESES, RES or Red Hat Expanded Support.
You are responsible for arranging access to Red Hat or CentOS base media repositories and installation media. |
SUSE does not provide support for Expanded Support systems on Uyuni. |
Traditional clients are not available on Expanded Support 8. Expanded Support 8 clients are only supported as Salt clients. |
Server Requirements
Before you begin, check that your Uyuni Server meets the requirements at installation:hardware-requirements.adoc.
Taskomatic uses one CPU core, and requires at least 3072 MB of RAM.
To ensure that taskomatic has access to enough memory, open the /etc/rhn/rhn.conf
configuration file, and add this line:
taskomatic.java.maxmemory=3072
Restart Taskomatic:
systemctl restart taskomatic
Add Client Tools
For Expanded Support clients, some required packages are contained on the Red Hat Enterprise Linux or CentOS installation media. You must have these packages installed before you can register a Expanded Support client.
The Expanded Support product is provided by SUSE Customer Center. This also includes the client tools package.
Before you register Expanded Support clients to your Uyuni Server, check that you have the corresponding Expanded Support product enabled, and the required channels are fully synchronized.
You need to select two different sets of channels, one for Expanded Support and the other for the Client Tools.
You will need an activation key associated with the correct Expanded Support channels. For more information about activation keys, see client-configuration:clients-and-activation-keys.adoc.
For Expanded Support 8 clients, add both the |
-
On the Uyuni Server, add the appropriate Expanded Support channels:
-
For Expanded Support 6:
From the Web UI, add
RHEL Expanded Support 6 x86_64
.From the command prompt, add
rhel-x86_64-server-6
andres6-suse-manager-tools-x86_64
. -
For Expanded Support 7:
From the Web UI, add
RHEL Expanded Support 7 x86_64
andSUSE Linux Enterprise Client Tools RES7 x86_64
.From the command prompt, add
rhel-x86_64-server-7
andres7-suse-manager-tools-x86_64
. -
For Expanded Support 8:
From the Web UI, add
RHEL8 Base x86_64
andSUSE Manager Tools for RHEL and ES 8 x86_64
.From the command prompt, add
rhel-x86_64-server-8
andres8-suse-manager-tools-x86_64

Synchronize the Uyuni Server with the SUSE Customer Center. You can do this using the Web UI, or by running
mgr-sync
at the command prompt. -
Add the new channel to your activation key.
There are two ways to check if a channel has finished synchronizing:
-
In the Uyuni Web UI, navigate to
, then click the channel associated to the repository. Navigate to theRepositories
tab, then clickSync
and checkSync Status
. -
Check the synchronization log file at the command prompt:
tail -f /var/log/rhn/reposync/<channel-label>.log
Each child channel will generate its own log during the synchronization progress. You will need to check all the base and child channel log files to be sure that the synchronization is complete.
The Expanded Support channels can be very large. The initial channel synchronization can sometimes take up to 24 hours. When the initial synchronization is complete, we recommended you clone the channel before you work with it. This gives you a backup of the original synchronization data. |
Add Base Media
The base Expanded Support channel does not contain any packages, because SUSE does not provide Red Hat Enterprise Linux or CentOS base media. You will need to obtain base media from Red Hat or CentOS, which you can add as a child channel to the Expanded Support parent channel. To ensure you have all the packages you need, use a full DVD image, not a minimal or JeOS image.
You can use Uyuni custom channels to set up the Red Hat Enterprise Linux or CentOS media. All packages on the base media are mirrored into a child channel.
Procedure: Creating a Red Hat Enterprise Linux or CentOS Custom Channel
|
-
In the Uyuni Web UI, navigate to
. -
Click Create Channel and set these parameters:
-
In the
Channel Name
field, type a name for your channel, specifying the OS name and architecture. -
In the
Channel Label
field, type a label for your channel, specifying the OS name and architecture. -
In the
Parent Channel
field, select the corresponding Red Hat Enterprise Linux or CentOS distribution channel for your architecture. The parent channel will not contain any packages. -
In the
Architecture
field, select the appropriate architecture. -
In the
Repository Checksum Type
field, selectsha1
. -
In the
Channel Summary
field, type a summary for your channel, specifying the OS name and architecture. -
In the
Organization Sharing
field, selectPublic
.
-
-
Click Create Channel.
-
Add the new channel to your activation key.
-
On the Uyuni Server, at the command prompt, as root, copy the base media image to the
/tmp/
directory. -
Create a directory to contain the media content. Replace
<os_name>
with eithersleses6
,sleses7
orsleses8
:mkdir -p /srv/www/htdocs/pub/<os_name>
-
Mount the image:
mount -o loop /tmp/<iso_filename> /srv/www/htdocs/pub/<os_name>
When the image is mounted, you can synchronize the base media. To manually synchronize the channels, navigate to
. Click each channel in the list, and navigate to menu:[Repositories > Sync]. Click Sync Now to begin synchronization immediately. You can also create a synchronization schedule from this screen.Monitor Synchronization Progress
You can check if a channel has finished synchronizing:
-
In the Uyuni Web UI, navigate to
, then click on the channel associated to the repository. Navigate to theRepositories
, thenSync
and checkSync Status
-
Check the synchronization log file at the command prompt with
tail -f /var/log/rhn/reposync/channel-label.log
.Each child channel will generate its own log during the synchronization progress.
You will need to check all the base and child channel log files to be sure that the synchronization is complete.
Register Expanded Support Clients
Your Expanded Support clients are now ready to be registered.
For more information on registering your clients, see client-configuration:registration-overview.adoc.
To register and use SUSE Linux Enterprise Server with Expanded Support 6 clients, you need to configure the Uyuni Server to support older types of SSL encryption.
