Description Dave Neary 2014-12-03 23:33:15 UTC

Description of problem: Trying to install RDO Juno on 3 VMs (running on OpenStack), with --install-hosts=$IP1,$IP2,$IP3

I have tested that all hosts are accessible, and root log-in from remote is possible (with private SSH key).

Packstack gets quite far, and I get the following error:

10.3.11.176_nova.pp:                                 [ DONE ]  
10.3.11.178_nova.pp:                              [ ERROR ]    
Applying Puppet manifests                         [ ERROR ]

ERROR : Error appeared during Puppet run: 10.3.11.178_nova.pp
cYou will find full trace in log /var/tmp/packstack/20141203-223128-IBnshK/manifests/10.3.11.178_nova.pp.log
Please check log file /var/tmp/packstack/20141203-223128-IBnshK/openstack-setup.log for more information

Packstack fails to start the Nova service on one of the compute nodes. Some searching shows that this is because of an incorrect set-up in /etc/rabbitmq/rabbitmq.conf on the control host: 
https://ask.openstack.org/en/question/48329/openstack-juno-using-rdo-fails-installation-amqp-server-closed-the-connection/

How reproducible:

Every time.

Steps to Reproduce:
1. Install and update CentOS 7 on 3 hosts
2. Follow the Packstack Quick start instructions
3. Observe failure to start Neutron on compute hosts

Please let me know if there is a known workaround.

Comment 1 Dave Neary 2014-12-04 19:06:29 UTC

This is looking like NOTABUG - I was running the "hosts" on OpenStack instances, with security group rules which did not allow AMQP ingress for the control host.

The problem is that this is totally outside the guests, so I spent a ton of time figuring this out.

I initially added the following line to amqpp.pp in the rabbitmq class:
    config_variables => {"loopback_users" =>  "[]",},

but have now backed it out, and things continued to work. Looks like the main issue was the security groups.

Actually I believe this *is* a bug.  I filed bug 1175428.
