Mirantis (https://fuel.mirantis.com/)  supports Folsom on CentOS. I have installed RDO from RHAT.

To answer your first question, you only need one AMQP messenger, RabbitMQ and qpid are simply two different options. RabbitMQ is the default, but RedHat tends to lean towards qpid (for instance RDO, openstack.redhat.com, uses qpid). Because RabbitMQ is the default, you'll need to change rpc_backend in files like nova.conf and quantum.conf, for instance:


I don't know of any other repos for Folsom and CentOS other than EPEL. For Grizzly+ they've moved to http://repos.fedorapeople.org/repos/openstack/ , but there is no Folsom there.

I have been asked to setup Folsom for the first time.

I am currently following the documentation found at http://docs.openstack.org/folsom/openstack-compute/install/yum/content/compute-minimum-configuration-settings.html and there are two AMQP messaging solutions referenced.  One being referenced in RabbitMQ, and the other being 

qpid-cpp.  Based on comments I understand that I can just change nova.conf to use qpid and match the rest of the instructions as closely as possible.  

But using the same base documentation I have already configured and tested glance as much as I can at this stage and looking at /etc/glance/glance-api.conf it references a rabbit_host and qpid_host with defaults configured.

So my first question is, is it right to assume that you need only one messaging tool?  Or would most Folsom installs use both RabbitMQ and qpid together ?

The other question I have is do people see significant differences in the ease of getting Folsom up and running if you are using Ubuntu vs CentOS?

>From what I can see at the moment a lot of the Issues identified with Folsom have been identified and marked as fixed by openstack dev's but the issues still exist in the EPEL rpms.  Are there other repositories that people would recommend?  

As this is a new install I am guessing that a lot of people would recommend that we install Grizzly rather than Folsom, but currently this isn't an option, so thank you for any insight you care to share.

Have a Good day :)
