Note

For an overview of the OpenStack components and their interfaces, see the Architecture Guide (https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/).
The document includes tasks, such as database setup and firewall configuration, that are common to all components, and tasks that are specific to configuring each component.

1.1. Subscribe to the Required Channels

To install RHEL OpenStack Platform, you must register all systems in the OpenStack environment with Red Hat Subscription Manager, and subscribe to the required channels.

Procedure 1.1. Subscribing to the Required Channels

  1. Register your system with the Content Delivery Network, entering your Customer Portal user name and password when prompted: 
    # subscription-manager register
  2. Obtain detailed information about the Red Hat OpenStack Platform subscription available to you: 
    # subscription-manager list --available --matches '*OpenStack Platform*'
    This command should print output similar to the following: 
    +-------------------------------------------+
    Available Subscriptions

  3. Use the Pool ID printed by this command to attach the Red Hat OpenStack Platform entitlement: 
    # subscription-manager attach --pool=Pool ID
  4. Disable any irrelevant and enable the required channels: 
    # subscription-manager repos --disable=\* \
--enable=rhel-7-server-rpms \
--enable=rhel-7-server-openstack-7.0-rpms \
--enable=rhel-7-server-rh-common-rpms
  5. Run the yum update command and reboot to ensure that the most up-to-date packages, including the kernel, are installed and running. 
    # yum update
# reboot
You have successfully configured your system to receive Red Hat Enterprise Linux OpenStack Platform packages. You may use the yum repolist command to confirm the repository configuration again at any time.
