[Rdo-list] RabbitMQ issue when starting Nova service on compute node

[Dave Neary]

Hi all,

I hit an issue today when installing RDO on 3 nodes (VMs) - when I got
to the point of starting the Nova service on the compute nodes, the
install crapped out. Logs weren't helpful, but some webs earching
uncovered this Ask question:
https://ask.openstack.org/en/question/48329/openstack-juno-using-rdo-fails-installation-amqp-server-closed-the-connection/

It turns out that the default RabbitMQ config file does not allow remote
connection of "guest/guest" user.
https://www.rabbitmq.com/access-control.html

I created a bug for the issue here (didn't find one before):
https://bugzilla.redhat.com/show_bug.cgi?id=1170385

The fixes would be straightforward: use a non-guest AMQP user and
password, or enable remote connection for the RabbitMQ guest user. But I
can't figure out how to do either of those - I don't think that

    CONFIG_AMQP_AUTH_USER=amqp_user
    CONFIG_AMQP_AUTH_PASSWORD=PW_PLACEHOLDER

in the answer file are what I'm looking for, I don't see any way to
update the RabbitMQ config file in amqp.pp

There is another optiuon: use qpid as the AMQP provider - but I wanted
to do a default install if at all possible.

Has anyone else hit this issue, and how did you get past it?

Thanks,
Dave.
