In this chapter you will learn how to install the Administration Server from scratch. It will run on SUSE Linux Enterprise Server 12 SP2 and include the SUSE OpenStack Cloud extension and, optionally, the Subscription Management Tool (SMT) server. Prior to starting the installation, refer to Section 2.4, “Hardware Requirements” and Section 2.5, “Software Requirements” for the requirements.
Start the installation by booting into the SUSE Linux Enterprise Server 12 SP2 installation system. For an overview of a default SUSE Linux Enterprise Server installation, refer to the SUSE Linux Enterprise Server Installation Quick Start. Detailed installation instructions are available in the SUSE Linux Enterprise Server Deployment Guide. Both documents are available at http://www.suse.com/documentation/sles-12/.
The following sections will only cover the differences from the default installation process.
Registering SUSE Linux Enterprise Server 12 SP2 during the installation process is required for getting product updates and for installing the SUSE OpenStack Cloud extension. Refer to the SUSE Customer Center Registration section of the SUSE Linux Enterprise Server 12 SP2 Deployment Guide for further instructions.
After having successfully registered you will be asked whether to add the update repositories. If you agree, the latest updates will automatically be installed, ensuring that your system is on the latest patch level after the initial installation. It is strongly recommended to add the update repositories now. If you choose to skip, you need to perform an online update later, before starting the SUSE OpenStack Cloud Crowbar installation.
To register a product, you need to have a SUSE login. If you do not have such a login, create it at http://www.suse.com/login.
SUSE OpenStack Cloud is an extension to SUSE Linux Enterprise Server. Installing it during the SUSE Linux Enterprise Server installation is the easiest and recommended way to set up the Administration Server. To get access to the extension selection dialog, you need to register SUSE Linux Enterprise Server 12 SP2 during the installation. After a successful registration, the SUSE Linux Enterprise Server 12 SP2 installation continues with the . Choose and provide the registration key you have obtained by purchasing SUSE OpenStack Cloud. The registration and the extension installation require an Internet connection.
Alternatively, install the SUSE OpenStack Cloud after the SUSE Linux Enterprise Server 12 SP2 installation via › › . For details, refer to the section Installing Modules and Extensions from Online Channels of the SUSE Linux Enterprise Server 12 SP2 Deployment Guide.
Currently, Crowbar requires /opt
to be writable. It is
also recommended to create a separate partition
or volume formatted with XFS for /srv
with a size of
at least 30 GB.
The default file system on SUSE Linux Enterprise Server 12 SP2 is Btrfs with snapshots enabled.
SUSE OpenStack Cloud installs into /opt
, a directory that is
excluded from snapshots. Reverting to a snapshot may therefore break the
SUSE OpenStack Cloud installation. It is recommended to disable Btrfs snapshots on
the Administration Server.
Help on using the partitioning tool is available at the section Using the YaST Partitioner of the SUSE Linux Enterprise Server 12 SP2 Deployment Guide.
The final installation step, Installation Settings section of the SUSE Linux Enterprise Server 12 SP2 Deployment Guide.
, lets you configure various settings. For the Administration Server setup, you need to adjust the software selection and the firewall settings. For more information refer to theInstalling a minimal base system is sufficient to set up the Administration Server. The following patterns are the minimum requirement:

Choose the pattern in addition to the patterns listed above to install the SMT server software.
SUSE OpenStack Cloud requires to disable the firewall on the Administration Server. You can disable the firewall now in the section. In case your environment requires a firewall to be active at this stage of the installation, you can postpone disabling the firewall until doing the final network configuration (see Chapter 6, Service Configuration: Administration Server Network Configuration). Optionally you can also enable SSH access to the admin server here.
