Important

Registering RHEL or CentOS Linux directly with SUSE Customer Center is not currently supported.

This guide describes how to register with SUSE Manager. SUSE Manager is a lifecycle management system for mixed Linux environments. The SUSE Manager Server is registered with SUSE Customer Center, and other systems are registered as clients of SUSE Manager and receive packages from it directly.

To register with Repository Mirroring Tool, see Registering RHEL 8 or CentOS Linux 8 with RMT.

Procedure overview
Note
Note: SUSE Liberty Linux and SUSE Linux Enterprise Server with Expanded Support

SUSE Liberty Linux now provides what used to be covered by the SUSE Linux Enterprise Server with Expanded Support subscription. Some components might still use the Expanded Support name during the transition period.

2 Deploying SUSE Manager

See the following guide to install SUSE Manager on SUSE Linux Enterprise Micro, a lightweight, immutable operating system for containerized and virtual workloads: SUSE Manager Quick Start: Deploy SUSE Manager Server.

You can use most SUSE Liberty Linux subscriptions to register this machine. However, the Lite subscription only includes an entitlement for RMT, so if you want to use SUSE Manager instead you will need a separate SUSE Manager subscription.

Tip
Tip: Other installation options

For additional installation options, see the full SUSE Manager Installation and Upgrade Guide.

To deploy SUSE Manager in the public cloud, see SUSE Manager Public Cloud Guide.

Important
Important: SUSE Liberty Linux 8 repository size

The SUSE Liberty Linux 8 repositories will grow over time because older package versions are not removed. Based on the current[1] size of the repositories, to meet the 1.5 times size recommendation you will need approximately 515 GB of disk space for the default repositories.

If you need the optional Source and Debug repositories, you will need an additional 1365 GB available.
