Open Stack

Can you verify if the servers where rabbitmq instances are running are reachable from other nodes?

# rabbit_hosts=rabbit1:5672,rabbit2:5672,rabbit3:5672
Are the above hosts reachable?
If yes, check if rabbitmq is listening on correct ports:
netstat –nap | grep rabbit

Also, did you set up correct credentials and access for “openstack” user on all rabbitmq hosts?

# rabbitmqctl add_user openstack RABBIT_PASS
# rabbitmqctl set_permissions openstack ".*" ".*" ".*"

Subject: [Openstack] AMQP server is unreachable / AMQP server closed the connection. Check login credentials

Hello,
I am a new to OpenStack. I am deploying from scratch and my architecture as such:
2 servers - computes
3 servers - controllers
3 servers - SAN
1 server - network
On every controller node I have created lxc contrainer for every service, so I have 3 containers for every service, and each container live on bare server.
Operation system - Ubuntu 14.04 with cloud-archive:liberty on each server/container and there are no firewall enabled.
Messages server is RabbitMQ, with I have deployed step-by-steb from this guide: http://docs.openstack.org/ha-guide/controller-ha-rabbitmq.html#rabbitmq-services
My first try to launch instance was failed. From the log I assume that the problem is near the messages server. Here is some log.
