I have installed and configured RabbitMQ-server-2.8.6-1 on ubuntu 10.04.<br>
My java web application successfully connects using the library which is<br>
included in RabbitMQ-java-client-bin-2.8.<u></u>6.<br>
I repeated the same installation and configuration on centos 6.3.<br>
When the java application tries to connect to the server rabbit, takes<br>
the error:<br>
"com.rabbitmq.client.<u></u>MalformedFrameException: AMQP protocol version<br>
mismatch, we are version 0-9-1, server sent signature 1,1,0,10"<br>
<br></div>
I tried the same configuration on Ubuntu �and onCentos with<div class="im"><br>
RabbitMQ-server-2.7.1-1 and with the library AMQP-client-2.7.1.jar. The<br>
behavior is the same: it works on ubuntu but I have the same error<br>
message on centos<br>
<br>
someone can give me some indication about ?<br>

My guess is that on centos you have a Qpid server running on the 5672 port, rather than RabbitMQ (they speak different versions of the protocol). If you stop the qpidd service and start RabbitMQ you should be fine.<br>
