Registering SUSE Linux Enterprise Clients

This section contains information about registering clients running SUSE Linux Enterprise operating systems.

Add Software Channels

Before you register SUSE Linux Enterprise clients to your Uyuni Server, check that you have the SUSE Linux Enterprise product enabled, and the required channels are fully synchronized.

The products you need for this procedure are:

Table 1. SLE Products - WebUI
OS Version Product Name

SUSE Linux Enterprise Server 15 SP1

SUSE Linux Enterprise Server 15 SP1 x86_64

SUSE Linux Enterprise Server 15 SP2

SUSE Linux Enterprise Server 15 SP2 x86_64

Procedure: Adding Software Channels
  1. In the Uyuni Web UI, navigate to Admin  Setup Wizard  Products.

  2. Locate the appropriate products for your client operating system and architecture using the search bar, and check the appropriate product. This will automatically check all required channels. Click the arrow to see the complete list of related products, and ensure that any extra products you require are checked.

  3. Click Add Products and wait until the products have finished synchronizing.

To add the client tools, add these channels from the command prompt:

Table 2. OpenSUSE Channels - CLI
OS Version Client Channel

SUSE Linux Enterprise Server 15 SP1

sles15-sp1-uyuni-client

SUSE Linux Enterprise Server 15 SP2

sles15-sp2-uyuni-client

Procedure: Adding Software Channels at the Command Prompt
  1. At the command prompt on the Uyuni Server, as root, use the spacewalk-common-channels command to add the appropriate channels:

    spacewalk-common-channels \
    <base_channel_name> \
    <child_channel_name_1> \
    <child_channel_name_2> \
    ... <child_channel_name_n>
  2. Synchronize the channels:

    mgr-sync refresh --refresh-channels

Check Synchronization Status

Procedure: Checking Synchronization Progress
  1. In the Uyuni Web UI, navigate to Software  Manage  Channels, then click the channel associated to the repository.

  2. Navigate to the Repositories tab, then click Sync and check Sync Status.

Procedure: Checking Synchronization Progress from the Command Prompt
  1. At the command prompt on the Uyuni Server, as root, use the tail command to check the synchronization log file:

    tail -f /var/log/rhn/reposync/<channel-label>.log
  2. Each child channel generates 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.

SUSE Linux Enterprise channels can be very large. Synchronization can sometimes take several hours.

Trust GPG Keys on Clients

By default, some operating systems do not trust the GPG key for the Uyuni client tools. The clients can be successfully bootstrapped without the GPG key being trusted. However, you will not be able to install new client tool packages or update them until the keys are trusted.

Procedure: Trusting GPG Keys on Clients
  1. On the Uyuni Server, at the command prompt, check the contents of the /srv/www/htdocs/pub/ directory. This directory contains all available public keys. Take a note of the key that applies to the client you are registering.

  2. Open the relevant bootstrap script, locate the ORG_GPG_KEY= parameter and add the required key. For example:

    uyuni-gpg-pubkey-0d20833e.key

    You do not need to delete any previously stored keys.

  3. If you are bootstrapping clients from the Uyuni Web UI, you will need to use a Salt state to trust the key. Create the Salt state and assign it to the organization. You can then use an activation key and configuration channels to deploy the key to the clients.

Register Clients

To register your SUSE Linux Enterprise clients, you need a bootstrap repository. By default, bootstrap repositories are automatically created, and regenerated daily for all synchronized products. You can manually create the bootstrap repository from the command prompt, using this command:

mgr-create-bootstrap-repo --with-custom-channels
