ActiveMQ拓展连接
此例简单介绍基于Docker的activemq安装与集群搭建
一 ：安装
1.获取activemq镜像

docker pull webcenter/activemq

 2.启动容器

docker run --name activemq -p 61616:61616 -e ACTIVEMQ_ADMIN_LOGIN=admin -e ACTIVEMQ_ADMIN_PASSWORD=123 --restart=always -d activemq:latest

 二 ：集群搭建
1.activemq.xml

<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd">

        <!-- Allows us to use system properties as variables in this configuration file -->
        <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
            <property name="locations">
                <value>file:${activemq.conf}/credentials.properties</value>
            </property>
        </bean>

        <!-- Allows accessing the server log -->
        <bean id="logQuery" class="io.fabric8.insight.log.log4j.Log4jLogQuery"
            lazy-init="false" scope="singleton"
            init-method="start" destroy-method="stop">
        </bean>

        <!--
            The <broker> element is used to configure the ActiveMQ broker.
        -->
        <broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}">

            <destinationPolicy>
                <policyMap>
                    <policyEntries>
                        <policyEntry topic=">" >
                            <pendingMessageLimitStrategy>
                                <constantPendingMessageLimitStrategy limit="1000"></constantPendingMessageLimitStrategy>
                            </pendingMessageLimitStrategy>
                        </policyEntry>
                    </policyEntries>
                </policyMap>
            </destinationPolicy>
            <managementContext>
                <managementContext createConnector="false"></managementContext>
            </managementContext>
            <persistenceAdapter>
                <kahaDB directory="${activemq.data}/kahadb"></kahaDB>
            </persistenceAdapter>
            <systemUsage>
                <systemUsage>
                    <memoryUsage>
                        <memoryUsage percentOfJvmHeap="70" ></memoryUsage>
                    </memoryUsage>
                    <storeUsage>
                        <storeUsage limit="100 gb"></storeUsage>
                    </storeUsage>
                    <tempUsage>
                        <tempUsage limit="50 gb"></tempUsage>
                    </tempUsage>
                </systemUsage>
            </systemUsage>

            <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>
                <transportConnector name="amqp" uri="amqp://0.0.0.0:5672?maximumConnections=1000&wireFormat.maxFrameSize=104857600"></transportConnector>
                <transportConnector name="stomp" uri="stomp://0.0.0.0:61613?maximumConnections=1000&wireFormat.maxFrameSize=104857600"></transportConnector>
                <transportConnector name="mqtt" uri="mqtt://0.0.0.0:1883?maximumConnections=1000&wireFormat.maxFrameSize=104857600"></transportConnector>
                <transportConnector name="ws" uri="ws://0.0.0.0:61614?maximumConnections=1000&wireFormat.maxFrameSize=104857600"></transportConnector>
            </transportConnectors>

            <!-- destroy the spring context on shutdown to stop jetty -->
            <shutdownHooks>
                <bean xmlns="http://www.springframework.org/schema/beans" class="org.apache.activemq.hooks.SpringContextHook" ></bean>
            </shutdownHooks>

        </broker>

        <import resource="jetty.xml"></import>
</beans>

 2.首先在Broker-A节点中添加networkConnector节点

<networkConnectors> 
    <networkConnector uri="static:(tcp://0.0.0.0:61617)" userName="admin" password="123" duplex="false" ></networkConnector>
</networkConnectors>

 3.修改Broker-A节点中的服务提供端口为61616

<transportConnectors>
    <transportConnector name="openwire" uri="tcp://0.0.0.0:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600" ></transportConnector>
</transportConnectors>

 4.在Broker-B节点中添加networkConnector节点

<networkConnectors> 
    <networkConnector uri="static:(tcp:// 0.0.0.0:61616)" userName="admin" password="123" duplex="false" ></networkConnector>
</networkConnectors>

 5.修改Broker-A节点中的服务提供端口为61616

<transportConnectors>
    <transportConnector name="openwire" uri="tcp://0.0.0.0:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600" ></transportConnector>
</transportConnectors>

 6.分别启动容器

docker run --name activemq1 -p 61616:61616 -v /showcase/activemq/activemq1.xml:/opt/activemq/conf/activemq.xml -e ACTIVEMQ_ADMIN_LOGIN=admin -e ACTIVEMQ_ADMIN_PASSWORD=123 --restart=always -d activemq:latest

docker run --name activemq2 -p 61617:61616 -v /showcase/activemq/activemq2.xml:/opt/activemq/conf/activemq.xml -e ACTIVEMQ_ADMIN_LOGIN=admin -e ACTIVEMQ_ADMIN_PASSWORD=123 --restart=always -d activemq:latest1
