Enter Database Credentials for a new MariaDB database user, then select Next. The new user is created.

If a password for the MariaDB root user is already set, enter the password when prompted, then select OK.

If no password is set for the MariaDB root user, enter and confirm a new password when prompted, then select OK.

Enter a Common Name for the SSL certificates. The common name is usually the FQDN of the server.

On the RMT server, update the available product and repository metadata:

# rmt-cli sync

Synchronization is also performed automatically by rmt-server-sync.timer. You can check the status and the next scheduled sync time with the following command:

# systemctl status rmt-server-sync.timer

Enable SUSE Liberty Linux using the product ID 1921:

# rmt-cli product enable 1921
Found product by target 1921: SUSE Linux Enterprise Server with Expanded Support 8 x86_64.
Enabling SUSE Linux Enterprise Server with Expanded Support 8 x86_64:
  SUSE Linux Enterprise Server with Expanded Support 8 x86_64:
    Enabled repository RES-8-Updates.
    Enabled repository RES-AS-8-Updates.
    Enabled repository RES-CB-8-Updates.

This enables all of the default repositories associated with the product.

If your subscription includes the High Availability extension, enable the extension using the product ID 1922:

# rmt-cli product enable 1922
Found product by target 1922: SUSE Linux Enterprise High Availability Extension with Expanded Support 8 x86_64.
Enabling SUSE Linux Enterprise High Availability Extension with Expanded Support 8 x86_64:

    Enabled repository RES-8-HA-Updates.

To check whether the High Availability extension is available, run this command: rmt-cli products list --all --name="Expanded Support" --version=8

If you also need the Source or Debug repositories, find and enable them with the following commands:

# rmt-cli repo list --all | grep RES-
# rmt-cli repo enable REPO_ID

Start package mirroring for the enabled repositories:

# rmt-cli mirror

Packages are downloaded to the RMT server once per day by rmt-server-mirror.timer. You can check the status and the next scheduled download time with the following command:

# systemctl status rmt-server-mirror.timer

Disable the RHEL or CentOS repositories in /etc/yum.repos.d by setting enabled=0 in each .repo file.

Download the rmt-client-setup-res script:

# curl http://RMT_SERVER/tools/rmt-client-setup-res --output rmt-client-setup-res

Run the rmt-client-setup-res script with the URL of the RMT server as a parameter:

# sh rmt-client-setup-res https://RMT_SERVER

The script performs the following tasks:

If the script works, you will see Successfully registered system. If the script fails, see Section 6, “Troubleshooting” for potential solutions.

Verify the installed product:

# SUSEConnect --status-text

You should see the following output:

Installed Products:

Verify the available repositories:

# dnf repolist

If your subscription includes the High Availability extension, activate it with the following command:

# SUSEConnect –p RES-HA/8/x86_64

To check whether the extension is available, run the SUSEConnect --list-extensions command.

Run the update command to make sure there are no errors:

# dnf update
