[rabbitmq-discuss] How to use HAProxy as a load balancer in RabbitMQ cluster?

[Rajasekhar P]

Thanks Marutha for the reply. Here, HAProxy is running on xxx.xxx.xxx.xxx
machine and listening port is 5720 . While getting the connection at
producer and consumer end, do we need to use this ip address or IP
addresses where RabbitMQ nodes are running in cluster?

CachingConnectionFactory connectionFactory = new CachingConnectionFactory(
"xxx.xxx.xxx.xxx");

(OR)

CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
connectionFactory.setAddresses("ip_addr2:5672,ip_addr2:5672");


Thanks in advance.
