⁠Chapter 3. Installing the User Interface

Setting up an enterprise Red Hat Enterprise Linux OpenStack Platform environment involves provisioning that environment using the Red Hat Enterprise Linux OpenStack Platform installer. The installer is a graphical user interface that provides functions for managing the provisioning of Red Hat Enterprise Linux OpenStack Platform components on a set of machines.

There are two main methods for setting up a machine on which to run the installer: manually installing Red Hat Enterprise Linux 6.6 on a machine and configuring the required repositories, or by using the installer live CD. The key difference between these methods is in how the base operating system and packages are installed; all steps from installing the Red Hat Enterprise Linux OpenStack Platform installer are identical for both methods. This guide outlines how to manually configure the required channels and repositories on a machine where Red Hat Enterprise Linux 6.6 is installed. For information on how to use the installer live CD, see How to Install the Red Hat Enterprise Linux OpenStack Platform Installer Using the Live CD.

After you have set up this machine, there are three key steps to the provisioning process: installing the user interface for the Red Hat Enterprise Linux OpenStack Platform installer, adding hosts to the user interface onto which to provision the environment, and then provisioning the environment. This guide outlines these steps and provides additional information on how to manually configure aspects of the installer.

Warning

Upgrading the Red Hat Enterprise Linux OpenStack Platform installer is not currently supported. To use the latest version of the installer, you must use a fresh installation.

Important

The role of the installer is to provision Red Hat Enterprise Linux OpenStack Platform environments and manage the life cycle of the hosts in that environment. After you have provisioned your environment, all additional configuration of Red Hat Enterprise Linux OpenStack Platform components on hosts you have provisioned must be performed manually on those hosts. For more information, see Section 6.6.4, “Next Steps”.

⁠3.1. Subscribing to the Required Channels Using Subscription Manager

To install the RHEL OpenStack Platform installer user interface, you must register the system where the user interface will be installed with Red Hat Subscription Manager, and subscribe to the required channels.

⁠

Procedure 3.1. Subscribing to the Required Channels Using Subscription Manager

Register your system with the Customer Delivery Network, entering your Customer Portal user name and password when prompted:
```
# subscription-manager register
```

Find entitlement pools containing the channels required to install the Red Hat Enterprise Linux OpenStack Platform Installer.

# subscription-manager list --available | grep -A8 "Red Hat Enterprise Linux Server"
# subscription-manager list --available | grep -A8 "Red Hat Enterprise Linux OpenStack Platform"

Use the pool identifiers located in the previous step to attach the Red Hat Enterprise Linux 6 Server and Red Hat Enterprise Linux OpenStack Platform entitlements:
```
# subscription-manager attach --pool=pool_id
```

Enable the required channels:

# subscription-manager repos --enable=rhel-6-server-rpms
# subscription-manager repos --enable=rhel-6-server-openstack-foreman-rpms
# subscription-manager repos --enable=rhel-server-rhscl-6-rpms
