1 Introduction #
SUSE Liberty Linux 7 has reached the end of general support and is now in LTSS (Long Term Service Support).
If you have a SUSE Liberty Linux subscription but do not have an LTSS subscription, you can continue to use your systems. However, registering new RHEL 7 or CentOS Linux 7 systems with the general subscription is no longer supported.
To register new RHEL 7 or CentOS Linux 7 systems, and to continue receiving new updates for existing systems, you must use an LTSS subscription.
Additionally, the optional High Availability extension is no longer supported with SUSE Liberty Linux LTSS 7. You must remove this product from your system before you can register with an LTSS subscription.
If you previously registered your systems with a general subscription and want to move them to an LTSS subscription, see Section 3, “Registering RHEL or CentOS Linux with SUSE Manager”.
SUSE Liberty Linux is a technology and support solution for mixed Linux environments. With a SUSE Liberty Linux subscription, you can register and update Red Hat Enterprise Linux and CentOS Linux.
The following table shows which Linux distributions are supported by each subscription. These subscriptions also include an entitlement for a registration tool to manage package updates.
| Subscription | Supported distributions | Registration options |
|---|---|---|
SUSE Liberty Linux Enterprise |
CentOS Linux Red Hat Enterprise Linux SUSE Linux Enterprise Server |
SUSE Manager Repository Mirroring Tool |
SUSE Liberty Linux Professional |
CentOS Linux Red Hat Enterprise Linux |
SUSE Manager Repository Mirroring Tool |
SUSE Liberty Linux Basic | CentOS Linux |
SUSE Manager Repository Mirroring Tool |
SUSE Liberty Linux Lite |
CentOS Linux Includes one entitlement for SLES to host RMT | Repository Mirroring Tool |
CentOS Stream is not supported.
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 7 or CentOS Linux 7 with RMT.
If SUSE Manager is already set up and you only need to register your RHEL 7 or CentOS Linux 7 system, skip straight to Section 3, “Registering RHEL or CentOS Linux with SUSE Manager”.
If you still need to set up SUSE Manager, start with Section 2, “Deploying SUSE Manager”.
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.
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.
The SUSE Liberty Linux LTSS 7 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 15 GB of disk space for the default LTSS-Updates
repository. If you need the optional LTSS-Source and
LTSS-Debug repositories, you will need an additional 39 GB.
SUSE Liberty Linux LTSS 7 also has optional frozen BASE repositories
that contain the packages from the non-LTSS repositories. If you need these repositories,
to meet the 1.5 times size recommendation you will need approximately 210 GB for the
BASE-Updates repository and 730 GB for the
BASE-Source and BASE-Debug repositories.
3 Registering RHEL or CentOS Linux with SUSE Manager #
The repository structure has changed in SUSE Liberty Linux LTSS 7. If you previously registered your system with a general SUSE Liberty Linux subscription, follow the Client Configuration Guide again to add and synchronize the LTSS repositories.
To clean up the old repositories, see SUSE Manager Administration Guide: Remove Channels.
See the following guide to register Red Hat Enterprise Linux 7 or CentOS Linux 7 with SUSE Manager: SUSE Manager Client Configuration Guide: Registering SUSE Liberty Linux Clients.
CentOS Stream is not supported.
