Modify message queue content for Kilo as follows: 1) Use upstream repository to obtain recent version of RabbitMQ. * Only impacts Ubuntu. 2) Create "openstack" account instead of using the "guest" account. 3) Replace "message broker" with "message queue" to improve wording. * Additional patches should implement this change.

<title>Message queue</title>
|
|
<para>OpenStack uses a <glossterm>message queue</glossterm> to coordinate
|
|
operations and status information among services. The message queue
|
|
service typically runs on the controller node. OpenStack supports several
|
|
message queue services including <application>RabbitMQ</application>,
|
|
<application>Qpid</application>, and <application>ZeroMQ</application>.
|
|
However, most distributions that package OpenStack support a particular
|
|
message queue service. This guide implements the RabbitMQ message queue
|
|
service because most distributions support it. If you prefer to implement
|
|
a different message queue service, consult the documentation associated
|
|
with it.</para>
