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#tar zxvf jdk-8u112-linux-x64.tar.gz#vi /etc/profile       添加以下内容export JAVA_HOME=/opt/jdk-8u112
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
#source /etc/profile
#java -version
java version "1.8.0_12"
Java(TM) SE Runtime Environment (build 1.8.0_12-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.12-b03, mixed mode)

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 -zxvf apache-activemq-5.14.5-bin.tar.gz
# vi conf/activemq.xml   192.168.1.104上进行配置（写入192.168.1.105:61626）<beansxmlns="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.xsdhttp://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd"><bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><value>file:${activemq.conf}/credentials.properties</value></property></bean><broker xmlns="http://activemq.apache.org/schema/core" brokerName="activemq-1"><networkConnectors><networkConnector uri="static:(tcp://192.168.1.105:61626)"/></networkConnectors><persistenceAdapter><kahaDB directory="${activemq.data}/kahadb"/></persistenceAdapter><transportConnectors><transportConnector name="openwire"uri="tcp://0.0.0.0:61616?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/></transportConnectors></broker><import resource="jetty.xml"/>
</beans>同理，在192.168.1.105上配置（写入192.168.1.104:61616）#vi conf/activemq.xml
<beansxmlns="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.xsdhttp://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd"><bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><value>file:${activemq.conf}/credentials.properties</value></property></bean><broker xmlns="http://activemq.apache.org/schema/core" brokerName="activemq-1"><networkConnectors><networkConnector uri="static:(tcp://192.168.1.104:61616)"/></networkConnectors><persistenceAdapter><kahaDB directory="${activemq.data}/kahadb"/></persistenceAdapter><transportConnectors><transportConnector name="openwire"uri="tcp://0.0.0.0:61626?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/></transportConnectors></broker><import resource="jetty.xml"/>
</beans>

配置完后，我们分别启动，

# bin/activemq start
#tail -f data/activemq.log 查看日志  可以看到已经建立连接2017-05-12 09:33:43,404 | INFO  | Establishing network connection from vm://activemq-1?async=false&create=false to tcp://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：

<bean id="jmsFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop"><property name="connectionFactory"><bean class="org.apache.activemq.ActiveMQConnectionFactory"><!--broker服务的地址--><property name="brokerURL" value="failover:(tcp://192.168.1.104:61616,tcp://192.168.1.105:61626)"/>...</bean></property>
</bean>

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。
