Hi, Option 2 is afaik the most stable option. Please also check your "durable"-setting in openstack and "replication"-policies in rabbitmq. I would suggest to use * durable-queue without replication *OR* * non-durable-queue with replication *OR* * do it the big-scale-way (f.e. vexxhost) and run one rabbitmq server per service and HA (failover) is done by some external service (like k8s, pacemaker, ...)

Hi,

I have been trying to configure HA for rabbitmq service for my Openstack installation. I found varying options on the Internet. I am facing some issues with rabbitmq with HAproxy.

Option 1. I want to know if victoria supports the following configuration directive for openstack services.

rabbit_hosts=rabbit1:5672,rabbit2:5672,rabbit3:5672

as told in this guide

https://docs.openstack.org/ha-guide/control-plane-stateful.html

Option 2. Can we configure as follows:

transport_url = rabbit://RABBIT_USER:RABBIT_PASS@rabbit1:5672, RABBIT_USER:RABBIT_PASS@rabbit2:5672,RABBIT_USER:RABBIT_PASS@rabbit3:5672

Option 3. I have been using this configuration in haproxy

listen rabbitmq_cluster_openstack bind controllers:5672 mode tcp balance roundrobin server controller1 controller1:5672 check inter 2000 rise 2 fall 5 server controller2 controller2:5672 backup check inter 2000 rise 2 fall 5

I am getting the following error in my log files for all the services.

2021-04-28 09:59:05.857 129188 INFO oslo.messaging._drivers.impl_rabbit [-] [bbf40d1a-e095-47ad-8629-931af485d4cf] Reconnected to AMQP server on controllers:5672 via [amqp] client with port 44818.

I have set transport_url as follows:

...

transport_url = rabbit://openstack:rabbit123@controllers:5672

The error goes away if I change host to controller1 or controller.

Please suggest which is the recommended one of the 3.

Thanks in advance -- Shalabh Goel
