3 Installing the Cloud Lifecycle Manager server Edit source

This chapter will show how to install the Cloud Lifecycle Manager from scratch. It will run on SUSE Linux Enterprise Server 12 SP3, include the SUSE OpenStack Cloud extension, and, optionally, the Subscription Management Tool (SMT) server.

3.1 Registration and Online Updates Edit source

Registering SUSE Linux Enterprise Server 12 SP3 during the installation process is required for getting product updates and for installing the SUSE OpenStack Cloud extension. Refer to https://documentation.suse.com/sles/12-SP5/single-html/SLES-deployment/#sec-i-yast2-conf-manual-cc for further instructions.

After a successful registration 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. We strongly recommend adding the update repositories immediately. If you choose to skip this step you need to perform an online update later, before starting the installation.

Note
Note: SUSE Login Required

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/.

3.2 Starting the Operating System Installation Edit source

Important
Important

Installing SUSE Linux Enterprise Server for SUSE OpenStack Cloud requires the following steps, which are different from the default SUSE Linux Enterprise Server installation process.

Note
Note

For an overview of a default SUSE Linux Enterprise Server installation, refer to https://documentation.suse.com/sles/12-SP5/single-html/SLES-installquick/#art-sle-installquick.

Start the installation by booting into the SUSE Linux Enterprise Server 12 SP3 installation system.

3.3 Partitioning Edit source

Create a custom partition setup using the Expert Partitioner. The following setup is required:

  • Two partitions are needed: one for boot, EFI or UEFI, and one for everything else.

  • If the system is using a UEFI BIOS, there must be a UEFI boot partition.

  • An LVM setup with no encryption is recommended, Btrfs will work. The file system must contain:

    • a volume group named ardana-vg on the first disk (/dev/sda)

    • a volume named root with a size of 50GB and an ext4 filesystem

  • no separate mount point for /home

  • no swap partition or file (No swap is a general OpenStack recommendation. Some services such as rabbit and cassandra do not perform well with swapping.)

3.4 Creating a User Edit source

Setting up Cloud Lifecycle Manager requires a regular user which you can set up during the installation. You are free to choose any available user name except for ardana, because the ardana user is reserved by SUSE OpenStack Cloud.

3.5 Installation Settings Edit source

With Installation Settings, you need to adjust the software selection for your Cloud Lifecycle Manager setup. For more information refer to the https://documentation.suse.com/sles/12-SP5/single-html/SLES-deployment/#sec-i-yast2-proposal.

Important
Important: Additional Installation Settings

The default firewall must be disabled, as SUSE OpenStack Cloud enables its own firewall during deployment.

SSH must be enabled.

Set text as the Default systemd target.

3.5.1 Software Selection Edit source

Installing a minimal base system is sufficient to set up the Administration Server. The following patterns are the minimum required:

  • Base System

  • Minimal System (Appliances)

  • Meta Package for Pattern cloud-ardana (in case you have chosen to install the SUSE OpenStack Cloud Extension)

  • Subscription Management Tool (optional, also see Tip: Installing a Local SMT Server (Optional))

  • YaST2 configuration packages

Tip
Tip: Installing a Local SMT Server (Optional)

If you do not have a SUSE Manager or SMT server in your organization, or are planning to manually update the repositories required for deployment of the SUSE OpenStack Cloud nodes, you need to set up an SMT server on the Administration Server. Choose the pattern Subscription Management Tool in addition to the patterns listed above to install the SMT server software.

3.5.2 Installing the SUSE OpenStack Cloud Extension Edit source

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 Cloud Lifecycle Manager. To get access to the extension selection dialog, you need to register SUSE Linux Enterprise Server 12 SP3 during the installation. After a successful registration, the SUSE Linux Enterprise Server 12 SP3 installation continues with the Extension & Module Selection. Choose SUSE OpenStack Cloud 8 and provide the registration key you obtained by purchasing SUSE OpenStack Cloud. The registration and the extension installation require an Internet connection.

If you do not have Internet access or are not able to register during installation, then once Internet access is available for the Cloud Lifecycle Manager do the following steps:

  1. tux > sudo SUSEConnect -r SLES_REGISTRATION_CODE

  2. List repositories to verify:

    ardana > zypper lr
  3. Refresh the repositories:

    tux > sudo zypper ref

Alternatively, install the SUSE OpenStack Cloud after the SUSE Linux Enterprise Server 12 SP3 installation via YaST › Software › Add-On Products. For details, refer to https://documentation.suse.com/sles/12-SP5/single-html/SLES-deployment/#sec-add-ons-extensions.
