This chapter outlines the main requirements for setting up an environment in which to provision a Red Hat Enterprise Linux OpenStack Platform environment using the Red Hat Enterprise Linux OpenStack Platform installer, including the requirements for setting up and accessing the installer itself, and the hardware requirements for hosts on to which the installer provisions the environment.

⁠2.1. User Interface Environment Requirements

A typical deployment of the Red Hat Enterprise Linux OpenStack Platform installer requires:
  • A private network accessible by physical machines or virtual machines on which Red Hat Enterprise Linux OpenStack Platform components can be deployed. Services such as DHCP, DNS, and PXE must be disabled on this network because these services can interfere with the installer.
  • A machine running Red Hat Enterprise Linux on which to set up the installer. This guide outlines how to install the user interface on this machine. For this machine, 6 GB of memory is recommended; a minimum of 4 GB memory is required.

    Important

    The machine on which you set up the installer must have a fully qualified domain name that satisfies the following requirements:
    • Matches the domain of the network to be provisioned.
    • Does not conflict with any existing domains (to prevent resource conflicts).

    Important

    The installer can only run on Red Hat Enterprise Linux 6.6. To deploy Red Hat Enterprise Linux OpenStack Platform 5.0 on Red Hat Enterprise Linux 7.2 using the installer, you must first install the user interface for the installer on a Red Hat Enterprise Linux 6.6 system. From that system, you can then use the tool to deploy Red Hat Enterprise Linux OpenStack Platform 5.0 on Red Hat Enterprise Linux 7.2.
  • A machine that is a member of the private network and that also has access to external networks that can act as a router or gateway. The machine on which the user interface is installed can perform this function if required; see Appendix B, Configuring a Gateway for information on how to configure this machine to act as a gateway.
  • The details of a Customer Portal account for subscribing the machine on which to install the user interface and for subscribing all hosts in your RHEL OpenStack Platform environment, including the user name, password, the ID of pools to attach, the names of channels to enable, and the details of a HTTP proxy, if any.
