<para>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

<para>All nodes require Internet access to install OpenStack packages
|
|
and perform maintenance tasks such as periodic updates. In most
|
|
cases, nodes should obtain Internet access through the management
|
|
network interface. For simplicity, the network diagrams in this guide
|
|
only show Internet access for OpenStack network services.</para>
