Registering Oracle Linux Clients

This section contains information about registering traditional and Salt clients running Oracle Linux operating systems.

Oracle Linux repository URLs are available from SUSE Customer Center, but the packages and metadata are provided by Oracle, not by SUSE. Oracle Linux base media repositories are freely available for download from https://yum.oracle.com/.

Traditional clients are not available on Oracle Linux 8. Oracle Linux 8 clients are only supported as Salt clients.

Add Software Channels

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

The products you need for this procedure are:

Table 1. Oracle Products - WebUI
OS Version Product Name

Oracle Linux 6

Oracle Linux 6 x86_64

Oracle Linux 7

Oracle Linux 7 x86_64

Oracle Linux 8

Oracle Linux 8 x86_64

Procedure: Adding Software Channels
  1. In the SUSE Manager 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 automatically checks 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.

Oracle Linux 6 is now at end-of-life, and the ISO images provided in the repository are out of date. Bootstrapping new Oracle Linux 6 clients using these packages will fail. If you need to bootstrap new Oracle Linux 6 clients, follow the troubleshooting procedure in client-configuration:tshoot-clients.adoc.

Procedure: Adding Software Channels
  1. In the SUSE Manager 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 mandatory channels. Also all recommended channels are checked as long as the include recommended toggle is turned on. 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.

Alternatively, you can add channels at the command prompt. The channels you need for this procedure are:

Table 2. Oracle Channels - CLI
OS Version Base Channel

Oracle Linux 6

oraclelinux6-x86_64

Oracle Linux 7

oraclelinux7-x86_64

Oracle Linux 8

oraclelinux8-x86_64

Oracle Linux 6 is now at end-of-life, and the ISO images provided in the repository are out of date. Bootstrapping new Oracle Linux 6 clients using these packages will fail. If you need to bootstrap new Oracle Linux 6 clients, follow the troubleshooting procedure in client-configuration:tshoot-clients.adoc.

Procedure: Adding Software Channels at the Command Prompt
  1. At the command prompt on the SUSE Manager Server, as root, use the mgr-sync command to add the appropriate channels:

    mgr-sync add channel <channel_label_1>
    mgr-sync add channel <channel_label_2>
    mgr-sync add channel <channel_label_n>
  2. Synchronization starts automatically. If you want to synchronize the channels manually, use:

    mgr-sync sync --with-children <channel_name>
  3. Ensure the synchronization is complete before continuing.

The AppStream repository provides modular packages. This results in the SUSE Manager Web UI showing incorrect package information. You cannot perform package operations such as installing or upgrading directly from modular repositories using the Web UI or API.

You can use the AppStream filter with content lifecycle management (CLM) to transform modular repositories into regular repositories. Alternatively, you can use Salt states to manage modular packages on Salt clients, or use the dnf command on the client. For more information about CLM, see administration:content-lifecycle.adoc.

Check Synchronization Status

Procedure: Checking Synchronization Progress
  1. In the SUSE Manager Web UI, navigate to Admin  Setup Wizard and select the Products tab. This dialog displays a completion bar for each product when they are being synchronized.

  2. Alternatively, you can navigate to Software  Manage  Channels, then click the channel associated to the repository. 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 SUSE Manager 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 need to check all the base and child channel log files to be sure that the synchronization is complete.

Create an Activation Key

You need to create an activation key that is associated with your Oracle Linux channels.

For more information on activation keys, see client-configuration:activation-keys.adoc.

Trust GPG Keys on Clients

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

Procedure: Trusting GPG Keys on Clients
  1. On the SUSE Manager 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 SUSE Manager Web UI, you 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

Oracle Linux clients are registered in the same way as all other clients. For more information, see client-configuration:registration-overview.adoc.

To register and use Oracle Linux 6 clients, you need to configure the SUSE Manager Server to support older types of SSL encryption. For more information about how to resolve this error, see Registering Older Clients at client-configuration:tshoot-clients.adoc.
