<para>You can configure OpenStack Compute to use any
|
|
SQLAlchemy-compatible database. The database name is
|
|
<literal>nova</literal>. The <systemitem
|
|
class="service">nova-conductor</systemitem> service is the
|
|
only service that writes to the database. The other Compute
|
|
services access the database through the <systemitem
|
|
class="service">nova-conductor</systemitem> service.</para>
|
|
<para>To ensure that the database schema is current, run the following command:</para>
|
|
<screen><prompt>#</prompt> <userinput>nova-manage db sync</userinput></screen>
|
|
<para>If <systemitem class="service">nova-conductor</systemitem>
|
|
is not used, entries to the database are mostly written by the
|
|
<systemitem class="service">nova-scheduler</systemitem>
|
|
service, although all services must be able to update
|
|
entries in the database.</para>
|
|
<para>In either case, use the configuration option settings documented in
|
|
<xref linkend="config_table_nova_database"/> to configure the connection
|
|
string for the nova database.</para>
