1、安装JDK运行环境
#cd/opt #wget--no-check-certificate--no-cookies--header"Cookie:oraclelicense=accept-securebackup-cookie"http://download.oracle.com/otn-pub/java/jdk/8u112-b15/jdk-8u112-linux-x64.tar.gz #tarzxvfjdk-8u112-linux-x64.tar.gz #vi/etc/profile添加以下内容 exportJAVA_HOME=/opt/jdk-8u112 exportPATH=$JAVA_HOME/bin:$PATH exportCLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar #source/etc/profile #java-version javaversion"1.8.0_12" Java(TM)SERuntimeEnvironment(build1.8.0_12-b12) JavaHotSpot(TM)64-BitServerVM(build25.12-b03,mixedmode)
二、安装配置activemq
在这里我们配置Networks of Brokers集群模式
activemq-1与activemq-2这二个broker就互为主备，发给你的消息会同步到我，发给我的消息也会同步到你，实现了HA，示意图如下：192.168.1.104:61616<-->192.168.1.105:61626
这种HA方案的优点是占用的节点数更少(只需要2个节点),而且2个broker都可以响应消息的接收与发送，性能比zookeeper方案要好一些。
#wget
#tar-zxvfapache-activemq-5.14.5-bin.tar.gz
#viconf/activemq.xml192.168.1.104上进行配置（写入192.168.1.105:61626）
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd
http://activemq.apache.org/schema/corehttp://activemq.apache.org/schema/core/activemq-core.xsd">
<beanclass="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<propertyname="locations">
<value>file:${activemq.conf}/credentials.properties</value>
</property>
</bean>
<brokerxmlns="http://activemq.apache.org/schema/core"brokerName="activemq-1">
<networkConnectors>
<networkConnectoruri="static:(tcp://192.168.1.105:61626)"/>
</networkConnectors>
<persistenceAdapter>
<kahaDBdirectory="${activemq.data}/kahadb"/>
</persistenceAdapter>
<transportConnectors>
<transportConnectorname="openwire"
uri="tcp://0.0.0.0:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
</transportConnectors>
</broker>
<importresource="jetty.xml"/>
</beans>
同理，在192.168.1.105上配置（写入192.168.1.104:61616）
#viconf/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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd
http://activemq.apache.org/schema/corehttp://activemq.apache.org/schema/core/activemq-core.xsd">
<beanclass="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<propertyname="locations">
<value>file:${activemq.conf}/credentials.properties</value>
</property>
</bean>
<brokerxmlns="http://activemq.apache.org/schema/core"brokerName="activemq-1">
<networkConnectors>
<networkConnectoruri="static:(tcp://192.168.1.104:61616)"/>
</networkConnectors>
<persistenceAdapter>
<kahaDBdirectory="${activemq.data}/kahadb"/>
</persistenceAdapter>
<transportConnectors>
<transportConnectorname="openwire"
uri="tcp://0.0.0.0:61626?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
</transportConnectors>
</broker>
<importresource="jetty.xml"/>
</beans>
配置完后，我们分别启动，
#bin/activemqstart #tail-fdata/activemq.log查看日志可以看到已经建立连接 2017-05-1209:33:43,404|INFO|Establishingnetworkconnectionfromvm://activemq-1?async=false&create=falsetotcp://192.168.1.105:61626| org.apache.activemq.network.DiscoveryNetworkConnector|main
访问activemq 控制台
http://ip:8161/admin/(默认的账号：admin默认密码：admin）
Producer与Consumer连接到activemq时，配置文件可以这么写：
<beanid="jmsFactory"class="org.apache.activemq.pool.PooledConnectionFactory"destroy-method="stop"> <propertyname="connectionFactory"> <beanclass="org.apache.activemq.ActiveMQConnectionFactory"> <!--broker服务的地址--> <propertyname="brokerURL"value="failover:(tcp://192.168.1.104:61616,tcp://192.168.1.105:61626)"/> ... </bean> </property> </bean>
性能比zookeeper方案要好一些。
