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-fail... 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.

Turned out the main issue was that I was installing this in OpenStack instances, and forgot about the security group rules. Since those get enforced in the host, not in the guest, it was invisible to me - iptables looked fine. I did add that line to rabbitmq.conf, with Dan Radez's help, in /usr/lib/python2.7/site-packages/packstack/puppet/templates/amqp.pp in the rabbitmp class. I still have not had a successful run, but I've been hitting a different issue each time. My latest issue was due to using floating IP addresses for the hosts - mongodb would not bind to that address - so I had to switch to the internal IP addresses (unfortunately, as I understand those will not stay the same over time). After resolving that, I have now hit an issue with Swift ring failing to rebalance. I have no idea what that means or how to fix it, the information I have suggests that nuking from orbit and restarting is the best approach. Thanks, Dave.
