<title>Compute</title>
|

<para>The OpenStack Compute service is a cloud computing
|
||
fabric controller, the main part of an IaaS system. It can
|
||
be used for hosting and manging cloud computing systems.
|

This section describes the OpenStack Compute configuration

options.</para>

<title>Post-installation configuration</title>
|
||
|
||
<para>Configuring your Compute installation involves many
|
||
configuration files: the <filename>nova.conf</filename> file,
|
||
the <filename>api-paste.ini</filename> file, and related Image
|
||
and Identity management configuration files. This section
|
||
contains the basics for a simple multi-node installation, but
|
||
Compute can be configured many ways. You can find networking
|
||
options and hypervisor options described in separate
|
||
chapters.</para>

<para>The <filename>nova.conf</filename> file should have its

owner set to <literal>root:nova</literal>, and mode set to

<literal>0640</literal>, since the file could contain your

MySQL server’s username and password. You also want to ensure

<title>Configuring Resize</title>
|

<para>Resize (or Server resize) is the ability to change the

flavor of a server, thus allowing it to upscale or downscale
|
||
according to user needs. For this feature to work
|
||
properly, some underlying virt layers may need further
|

configuration; this section describes the required configuration

steps for each hypervisor layer provided by OpenStack.</para>
