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 -------------- next part -------------- An HTML attachment was scrubbed...
