Starting the ActiveMQ broker, results in an error
activemq-classic
Solution
Change the amqp port in activemq_home/conf/activemq.xml to something else like 5673 and restart activemq `<transportConnectors> <!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB --> <transportConnector name="openwire" uri="tcp://0.0.0.0:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/> <transportConnector name="amqp" uri="**amqp://0.0.0.0:5673**?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/> <transportConnector name="stomp" uri="stomp://0.0.0.0:61613?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/> <transportConnector name="mqtt" uri="mqtt://0.0.0.0:1883?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/> <transportConnector name="ws" uri="ws://0.0.0.0:61614?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/> </transportConnectors>`
Problem
I am trying to start the activemq broker on a Windows machine by following the instructions at http://activemq.apache.org/getting-started.html#GettingStarted-StartingActiveMQ After downloading the Windows binaries, I changed to the installation directory and launched the broker using bin/activemq as instructed. The launch fails and after scanning the wall of text I found the following error. ``` ERROR | Failed to start Apache ActiveMQ ([localhost, ID:[Computer ID]:1], java.io.IOException: Transport Connector could not be registered i n JMX: Failed to bind to server socket: amqp://0.0.0.0:5672?maximumConnections=1 000&wireFormat.maxFrameSize=104857600 due to: java.net.BindException: Address al ready in use: JVM_Bind) ``` The address already in use caused me to believe that another amqp broker, such as RabbitMQ or Qpid(both of which are installed), might have allocated the connection so I restarted my computer but with no success on eliminating the error. Can anyone give me some ideas on what to try to get ActiveMQ running properly.
