Matthew Kassawara 677d910899 [install] Fix environment structure
Address various structure and consistency issues with
environment content.

This patch only addresses the critical structure and
consistency problems that impact usability. A future
patch should address the larger, but less obvious problems
that mostly appeared during the RST conversion.

Environment

Note

The draft version of this guide focuses on the future Liberty release and will not work for the current Kilo release. If you want to install Kilo, you must use the Kilo version of this guide instead.

This section explains how to configure the controller and one compute node using the example architecture.

Although most environments include Identity, Image service, Compute, at least one networking service, and the dashboard, the Object Storage service can operate independently. If your use case only involves Object Storage, you can skip to swift after configuring the appropriate nodes for it. However, the dashboard requires at least the Image service, Compute, and Networking.

You must use an account with administrative privileges to configure each node. Either run the commands as the root user or configure the sudo utility.

obs

The systemctl enable call on openSUSE outputs a warning message when the service uses SysV Init scripts instead of native systemd files. This warning can be ignored.

For best performance, we recommend that your environment meets or exceeds the hardware requirements in figure-hwreqs. However, OpenStack does not require a significant amount of resources and the following minimum requirements should support a proof-of-concept environment with core services and several CirrOS instances:

  • Controller Node: 1 processor, 2 GB memory, and 5 GB storage
  • Compute Node: 1 processor, 2 GB memory, and 10 GB storage

To minimize clutter and provide more resources for OpenStack, we recommend a minimal installation of your Linux distribution. Also, you must install a 64-bit version of your distribution on each node.

A single disk partition on each node works for most basic installations. However, you should consider Logical Volume Manager (LVM) for installations with optional services such as Block Storage.

For first-time installation and testing purposes, many users elect to build each host as a virtual machine (VM). The primary benefits of VMs include the following:

  • One physical server can support multiple nodes, each with almost any number of network interfaces.
  • Ability to take periodic "snap shots" throughout the installation process and "roll back" to a working configuration in the event of a problem.

However, VMs will reduce performance of your instances, particularly if your hypervisor and/or processor lacks support for hardware acceleration of nested VMs.

Note

If you choose to install on VMs, make sure your hypervisor provides a way to disable MAC address filtering on the public network interface.
