Zookeeper+ActiveMQ集群搭建

搭建三台虚拟机安装centos7。要提前安装好jdk环境

1.环境准备,搭建三台虚拟机ip分别是

  • 192.168.192.130
  • 192.168.192.131
  • 192.168.192.134

192.168.192.134

62623

51513

8163

activemq-cluster/node3

 

 

2.搭建zookeeper环境(三个虚拟机操作一样)

  • 解压zookeeper-3.4.5.tar.gz 复制到/opt/usr/local下(三台虚拟机都这么做)
  • 配置zookeeper的环境变量。vim/etc/profile(配置完成后要记得source /etc/profile 生效修改)

JAVA_HOME=/usr/lib/java/jdk1.7 ZOOKEEPER_HOME=/usr/local/zookeeper-3.4.5 CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar PATH=$JAVA_HOME/bin:$ZOOKEEPER_HOME/bin:$PATH export JAVA_HOME CLASS_PATH ZOOKEEPER_HOME PATH

  • 修改zookeeper配置文件名,到zookeeper的conf目录下将zoo_sample.cfg文件改名为zoo.cfg

  $ mv zoo_sample.cfg zoo.cfg

  • 编辑zoo.cfg文件 

  $ vim zoo.cfg

# The number of milliseconds of each tick tickTime=2000 # The number of ticks that the initial # synchronization phase can take initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. #这个地方的目录地址改一下 dataDir=/usr/local/zookeeper-3.4.5/data #日志目录 dataLogDir=/usr/local/zookeeper-3.4.5/logs # the port at which the clients will connect clientPort=2181 # # Be sure to read the maintenance section of the # administrator guide before turning on autopurge. # # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance # # The number of snapshots to retain in dataDir #autopurge.snapRetainCount=3 # Purge task interval in hours # Set to "0" to disable auto purge feature #autopurge.purgeInterval=1 #配置三个server server.0=192.168.192.130:2888:3888 server.1=192.168.192.131:2888:3888 server.2=192.168.192.134:2888:3888

  • 在zookeeper-3.4.5目录下创建data文件夹和logs文件夹

  $ cd /usr/local/zookeeper-3.4.5

  $mkdir data

  $mkdir logs

  • 在三个虚拟机下的data文件夹下创建三个myid文件,并且三个文件里面分别写入0,1,2

  $ cd /usr/local/zookeeper-3.4.5/data

#192.168.192.130下 vim myid 在文件里面写入0,保存退出 #192.168.192.131下 vim myid 在文件里面写入1,保存退出 #192.168.192.134下 vim myid 在文件里面写入2,保存退出

  • 启动三个zookeeper

   $ zkServer.sh start

[root@localhost data]# zkServer.sh start JMX enabled by default Using config: /usr/local/zookeeper-3.4.5/bin/../conf/zoo.cfg Starting zookeeper ... STARTED [root@localhost data]#

  • ps:常用命令:

  启动: zkServer.sh start

  停止: zkServer.sh stop

  重启: zkServer.sh restart

  查看服务状态: zkServer.sh status

  • 遇到的问题1:

  用zkServer.sh start启动报错说zkServer.sh:未找到命令 就用 ./zkServer.sh start 来启动

  • 遇到的问题2: 

  三台虚拟机启动后用zkServer.sh status查看状态发现有错误

[root@localhost conf]# zkServer.sh status JMX enabled by default Using config: /usr/local/zookeeper-3.4.5/bin/../conf/zoo.cfg Error contacting service. It is probably not running.

  然后用$zkServer.sh start-foreground命令来启动查看启动日志 发现日志报错

  初步断定是防火墙的问题,我们关闭防火墙试试看能不能解决问题

  #关闭防火墙

  $ systemctl stop firewalld.service

  重新启动zookeeper我们发现可以使用了。问题解决

3、搭建ActiveMQ并和Zookeeper建立集群

  搭建三个ActiveMQ,分在三个服务器上,每一个服务器上一个。192.169.192.130是node1,192.168.192.131是node2,192.168.192.134是node3

  (1) 解压 tar -zxvf apache-activemq-5.14.1-bin.tar.gz

  (2) 创建文件夹mkdir /usr/local/activemq-cluster

  (3) 将第一步解压的文件夹移动到activemq-cluster下

  (4) 改名文件夹 mv apache-activemq-5.14.1 node1 (其他两台服务器也如此操作并分别改名为node2,node3)

  (5) 修改conf/activemq.xml文件 vim activemq.xml。修改其中的bind、zkAddress、bhotname、zkPath。

  (6) node1第一处修改:brokerName="active-cluster"

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="activemq-cluster" dataDirectory="${activemq.data}"> ...... </broker>

  (7)node1 第二处修改:

<persistenceAdapter> <!-- <kahaDB directory="${activemq.data}/kahadb"/> --> <replicatedLevelDB directory="${activemq.data}/leveldb" replicas="3" bind="tcp://0.0.0.0:62621" zkAddress="192.168.192.130:2181,192.168.192.131:2181,192.168.192.134:2181" hostname="192.168.192.130" zkPath="/activemq/leveldb-stores"/> </persistenceAdapter>

  (8)node1 第三处修改:修改name="openwire"

<transportConnectors> <!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB --> <transportConnector name="openwire" uri="tcp://0.0.0.0:51511?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="amqp" uri="amqp://0.0.0.0:5672?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="stomp" uri="stomp://0.0.0.0:61613?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="mqtt" uri="mqtt://0.0.0.0:1883?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="ws" uri="ws://0.0.0.0:61614?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> </transportConnectors>

  (9) node2 第一处修改

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="activemq-cluster" dataDirectory="${activemq.data}"> ...... </broker>

  (10) node2第二处修改

<persistenceAdapter> <!-- <kahaDB directory="${activemq.data}/kahadb"/> --> <replicatedLevelDB directory="${activemq.data}/leveldb" replicas="3" bind="tcp://0.0.0.0:62622" zkAddress="192.168.192.130:2181,192.168.192.131:2181,192.168.192.134:2181" hostname="192.168.192.131" zkPath="/activemq/leveldb-stores" /> </persistenceAdapter>

  (11) node2第三处修改参考

<transportConnectors> <!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB --> <transportConnector name="openwire" uri="tcp://0.0.0.0:51512?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="amqp" uri="amqp://0.0.0.0:5672?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="stomp" uri="stomp://0.0.0.0:61613?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="mqtt" uri="mqtt://0.0.0.0:1883?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="ws" uri="ws://0.0.0.0:61614?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> </transportConnectors>

  (12) node3第一处修改

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="activemq-cluster" dataDirectory="${activemq.data}"> ...... </broker>

  (13) node3第二处修改

<persistenceAdapter> <!-- <kahaDB directory="${activemq.data}/kahadb"/> --> <replicatedLevelDB directory="${activemq.data}/leveldb" replicas="3" bind="tcp://0.0.0.0:62623" zkAddress="192.168.192.130:2181,192.168.192.131:2181,192.168.192.134:2181" hostname="192.168.192.134" zkPath="/activemq/leveldb-stores" /> </persistenceAdapter>

  (14) node3第三处修改

<transportConnectors> <!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB --> <transportConnector name="openwire" uri="tcp://0.0.0.0:51513?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="amqp" uri="amqp://0.0.0.0:5672?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="stomp" uri="stomp://0.0.0.0:61613?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="mqtt" uri="mqtt://0.0.0.0:1883?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> <transportConnector name="ws" uri="ws://0.0.0.0:61614?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/> </transportConnectors>

4、集群搭建完毕,测试一下

  • 先启动zookeeper $ zkServer.sh start(有三个zookeeper,貌似第二个启动的是leader,用$zkServer.sh status查看)
  • 再启动activemq $ ./activemq start
  • 查看日志看是否出错 $ tailf node1/data/activemq.log(最先启动的是master,其他的都是slaver)
  • 在浏览器中输入http://192.168.192.130/admin来查看

5、用代码来测试一下

package com.lee; import javax.jms.Connection; import javax.jms.ConnectionFactory; import javax.jms.DeliveryMode; import javax.jms.Destination; import javax.jms.MessageProducer; import javax.jms.Session; import javax.jms.TextMessage; import org.apache.activemq.ActiveMQConnectionFactory; public class Sender { public static void main(String[] args) { try { //第一步:建立ConnectionFactory工厂对象,需要填入用户名、密码、以及要连接的地址,均使用默认即可,默认端口为"tcp://localhost:61616" ConnectionFactory connectionFactory = new ActiveMQConnectionFactory( ActiveMQConnectionFactory.DEFAULT_USER, ActiveMQConnectionFactory.DEFAULT_PASSWORD, "failover:(tcp://192.168.192.130:51511,tcp://192.168.192.131:51512,tcp://192.168.192.134:51513)?Randomize=false"); //第二步:通过ConnectionFactory工厂对象我们创建一个Connection连接,并且调用Connection的start方法开启连接,Connection默认是关闭的。 Connection connection = connectionFactory.createConnection(); connection.start(); //第三步:通过Connection对象创建Session会话(上下文环境对象),用于接收消息,参数配置1为是否启用是事务,参数配置2为签收模式,一般我们设置自动签收。 Session session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE); //第四步:通过Session创建Destination对象,指的是一个客户端用来指定生产消息目标和消费消息来源的对象,在PTP模式中,Destination被称作Queue即队列;在Pub/Sub模式,Destination被称作Topic即主题。在程序中可以使用多个Queue和Topic。 Destination destination = session.createQueue("first"); //第五步:我们需要通过Session对象创建消息的发送和接收对象(生产者和消费者)MessageProducer/MessageConsumer。 MessageProducer producer = session.createProducer(null); //第六步:我们可以使用MessageProducer的setDeliveryMode方法为其设置持久化特性和非持久化特性(DeliveryMode),我们稍后详细介绍。 //producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT); //第七步:最后我们使用JMS规范的TextMessage形式创建数据(通过Session对象),并用MessageProducer的send方法发送数据。同理客户端使用receive方法进行接收数据。最后不要忘记关闭Connection连接。 for(int i = 0 ; i < 500000 ; i ++){ TextMessage msg = session.createTextMessage("我是消息内容" + i); System.out.println("我是消息内容" + i); // 第一个参数目标地址 // 第二个参数 具体的数据信息 // 第三个参数 传送数据的模式 // 第四个参数 优先级 // 第五个参数 消息的过期时间 producer.send(destination, msg, DeliveryMode.NON_PERSISTENT, 0 , 1000L); System.out.println("发送消息:" + msg.getText()); Thread.sleep(1000); } if(connection != null){ connection.close(); } } catch (Exception e) { e.printStackTrace(); } } }

 

package com.lee; import javax.jms.Connection; import javax.jms.ConnectionFactory; import javax.jms.Destination; import javax.jms.MapMessage; import javax.jms.Message; import javax.jms.MessageConsumer; import javax.jms.Session; import javax.jms.TextMessage; import org.apache.activemq.ActiveMQConnectionFactory; public class Receiver { public static void main(String[] args) { try { //第一步:建立ConnectionFactory工厂对象,需要填入用户名、密码、以及要连接的地址,均使用默认即可,默认端口为"tcp://localhost:61616" ConnectionFactory connectionFactory = new ActiveMQConnectionFactory( ActiveMQConnectionFactory.DEFAULT_USER, ActiveMQConnectionFactory.DEFAULT_PASSWORD, "failover:(tcp://192.168.192.130:51511,tcp://192.168.192.131:51512,tcp://192.168.192.·34:51513)?Randomize=false"); //第二步:通过ConnectionFactory工厂对象我们创建一个Connection连接,并且调用Connection的start方法开启连接,Connection默认是关闭的。 Connection connection = connectionFactory.createConnection(); connection.start(); //第三步:通过Connection对象创建Session会话(上下文环境对象),用于接收消息,参数配置1为是否启用是事务,参数配置2为签收模式,一般我们设置自动签收。 Session session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE); //第四步:通过Session创建Destination对象,指的是一个客户端用来指定生产消息目标和消费消息来源的对象,在PTP模式中,Destination被称作Queue即队列;在Pub/Sub模式,Destination被称作Topic即主题。在程序中可以使用多个Queue和Topic。 Destination destination = session.createQueue("first"); //第五步:通过Session创建MessageConsumer MessageConsumer consumer = session.createConsumer(destination); while(true){ TextMessage msg = (TextMessage)consumer.receive(); if(msg == null) break; System.out.println("收到的内容:" + msg.getText()); } } catch (Exception e) { e.printStackTrace(); } } }
