ActiveMQ消息集群的搭建：
在本地创建一个文件夹，名为activemq，将ActiveMQ的安装包下载到这个文件夹中，我下载的版本是5.14.2，然后将其解压，修改名字为activemq-a，然后再复制两份，分别命名为activemq-b和activemq-c，再次新建一个share文件夹用于消息存储共享文件夹。
1.修改activemq-a中的配置
$ cd activemq-a/conf
$ vim activemq.xml
<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://0.0.0.0:5672?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>
<networkConnectors>
<networkConnector name="local_network" uri="static:(tcp://127.0.0.1:61617,tcp://127.0.0.1:61618)" />
</networkConnectors>
2.修改activemq-b中的配置
$ cd activemq-b/conf
$ vim activemq.xml
<persistenceAdapter>
<kahaDB directory="/home/huyj/Downloads/activemq/share"/>
</persistenceAdapter>
...
<transportConnectors>
<!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB -->
<transportConnector name="openwire" uri="tcp://0.0.0.0:61617?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
<!--<transportConnector name="amqp" uri="amqp://0.0.0.0:5672?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>
<networkConnectors>
<networkConnector name="network_a" uri="static:(tcp://127.0.0.1:61616)" />
</networkConnectors>
3.修改activemq-c中的配置
$ cd activemq-c/conf
$ vim activemq.xml
<persistenceAdapter>
<kahaDB directory="/home/huyj/Downloads/activemq/share"/>
</persistenceAdapter>
...
<transportConnectors>
<!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB -->
<transportConnector name="openwire" uri="tcp://0.0.0.0:61618?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
<!--<transportConnector name="amqp" uri="amqp://0.0.0.0:5672?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>
<networkConnectors>
<networkConnector name="network_a" uri="static:(tcp://127.0.0.1:61616)" />
</networkConnectors>
最后再修改activemq-a,activemq-b,activemq-c文件中conf下的jetty.xml，端口号分别改为8161,8162,8163
<bean id="jettyPort" class="org.apache.activemq.web.WebConsolePort" init-method="start">
<!-- the default port number for the web console -->
<property name="host" value="0.0.0.0"/>
<property name="port" value="8163"/>
</bean>
