Matthew Kassawara e0cdea9a6e [install] Liberty updates for cinder

Update cinder configuration for Liberty. Includes moving
basic host configuration of the block storage node to
environment section. Also addresses some consistency
issues, mostly from the RST conversion.

Changes and testing specific to distribution packages
primarily involve Ubuntu. Other distributions may require
additional patches.

After installing the operating system on each node for the architecture that you choose to deploy, you must configure the network interfaces. We recommend that you disable any automated network management tools and manually edit the appropriate configuration files for your distribution. For more information on how to configure networking on your distribution, see the documentation .

All nodes require Internet access for administrative purposes such as package installation, security updates, DNS, and NTP. In most cases, nodes should obtain internet access through the management network interface. To highlight the importance of network separation, the example architectures use private address space for the management network and assume that the physical network infrastructure provides Internet access via NAT or other method. The example architectures use routable IP address space for the public network and assume that the physical network infrastructure provides direct Internet access. In the provider networks architecture, all instances attach directly to the public network. In the self-service networks architecture, instances can attach to a private or public network. Private networks can reside entirely within OpenStack or provide some level of public network access using NAT.

The example architectures assume use of the following networks:

Management on 10.0.0.0/24 with gateway 10.0.0.1

Note

This network requires a gateway to provide Internet access to all nodes for administrative purposes such as package installation, security updates, DNS, and NTP.
Public on 203.0.113.0/24 with gateway 203.0.113.1

Note

This network requires a gateway to provide Internet access to instances in your OpenStack environment.

You can modify these ranges and gateways to work with your particular network infrastructure.

Note

Network interface names vary by distribution. Traditionally, interfaces use "eth" followed by a sequential number. To cover all variations, this guide simply refers to the first interface as the interface with the lowest number and the second interface as the interface with the highest number.

Unless you intend to use the exact configuration provided in this example architecture, you must modify the networks in this procedure to match your environment. Also, each node must resolve the other nodes by name in addition to IP address. For example, the controller name must resolve to 10.0.0.11, the IP address of the management interface on the controller node.

Warning

Reconfiguring network interfaces will interrupt network connectivity. We recommend using a local terminal session for these procedures.

Note

rdo or obs

Your distribution enables a restrictive firewall by default. During the installation process, certain steps will fail unless you alter or disable the firewall. For more information about securing your environment, refer to the OpenStack Security Guide.

ubuntu or debian

Your distribution does not enable a restrictive firewall by default. For more information about securing your environment, refer to the OpenStack Security Guide.
