ActiveMQ 基于zookeeper的主从(levelDB Master/Slave)搭建以及Spring-boot下使用

0:说明

  ActiveMQ 5.9.0新推出的主从实现,基于zookeeper来选举出一个master,其他节点自动作为slave实时同步消息。因为有实时同步数据的slave的存在,master不用担心数据丢失,所以leveldb会优先采用内存存储消息,异步同步到磁盘,所以该方式的activeMQ读写性能最好因为选举机制要超过半数,所以最少需要3台节点,才能实现高可用。如果集群是两台则master失效后slave会不起作用,所以集群至少三台。此种方式仅实现主备功能,避免单点故障,没有负载均衡功能。

1:环境准备

IP
192.168.3.10    server1
192.168.3.11    server2
192.168.3.12 server3

安装软件信息:

apache-activemq-5.13.0-bin.tar.gz

zookeeper-3.5.2-alpha.tar.gz

ZooInspector.zip

2:搭建Zookeeper集群

(1)将zookeeper-3.5.2-alpha.tar.gz文件解压到/home/wzh/zk目录;

(2)将zoo_sample.cfg复制一份为 zoo.cfg,并修改其配置信息

wzh@hd-master:~/zk/zookeeper-3.5.2-alpha/conf$ cp zoo_sample.cfg zoo.cfg

wzh@hd-master:~/zk/zookeeper-3.5.2-alpha/conf$vim zoo.cfg

tickTime=2000

initLimit=10

syncLimit=5

dataDir=/tmp/zookeeper

clientPort=2181

 

server.1=192.168.3.10:2888:3888

server.2=192.168.3.11:2888:3888

server.3=192.168.3.11:2888:3888

(3)创建/tmp/zookeeper目录

在该目录下创建名为myid的文件,内容为1(这个值随server而改变)

(4)将server1上的/home/wzh/zk/zookeeper-3.5.2-alpha文件夹复制到server2,server3,然后创建/tmp/zookeeper目录

在该目录下创建名为myid的文件,内容为2

(5)启动zookeeper

[192.168.3.10]

wzh@hd-master:~/zk/zookeeper-3.5.2-alpha/bin$ ./zkServer.sh start

ZooKeeper JMX enabled by default

Using config: /home/wzh/zk/zookeeper-3.5.2-alpha/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

[192.168.3.11]

wzh@hd-slave1:~/zk/zookeeper-3.5.2-alpha/bin$ ./zkServer.sh start

ZooKeeper JMX enabled by default

Using config: /home/wzh/zk/zookeeper-3.5.2-alpha/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

[192.168.3.12]

wzh@hd-slave2:~/zk/zookeeper-3.5.2-alpha/bin$ ./zkServer.sh start

ZooKeeper JMX enabled by default

Using config: /home/wzh/zk/zookeeper-3.5.2-alpha/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

3:搭建ActiveMQ集群

(1)将apache-activemq-5.13.0-bin.tar.gz解压到/home/wzh/amq

(2)修改activemq.xml配置文件

【1】将broker节点的brokerName设置为wzhamq

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

【2】将persistenceAdapter的持久化方式选用replicatedLevelDB,将kahaDB方式注释掉

 <persistenceAdapter>
         <!--
            <kahaDB directory="${activemq.data}/kahadb"/>
         -->
        <replicatedLevelDB 
                directory="${activemq.data}/leveldb" 
                replicas="3" 
                bind="tcp://0.0.0.0:0"        
                zkAddress="192.168.3.10:2181,192.168.3.11:2181"     
                hostname="192.168.3.10"          
                sync="local_disk"          
                zkPath="/activemq/leveldb-stores"/>
        </persistenceAdapter>

将apache-activemq-5.13.复制到11,12机器

wzh@hd-master:~/amq$ scp -r apache-activemq-5.13.0/ wzh@192.168.3.11:/tmp

修改配置文件中的hostname="192.168.3.11"   

修改配置文件中的hostname="192.168.3.12"   

(3)启动ActiveMQ

wzh@hd-master:~/amq$ ./apache-activemq-5.13.0/bin/activemq status
INFO: Loading '/home/wzh/amq/apache-activemq-5.13.0//bin/env'
INFO: Using java '/opt/java/jdk1.8.0_91/bin/java'
ActiveMQ is running (pid '2031')
wzh@hd-master:~/amq$

依次启动192.168.3.11,192.168.3.12机器

4:集群管理

(1)通过使用ZooInspector工具查看zookeeper集群情况

(2)http://192.168.3.10:8161/admin/ 默认用户名与口令为admin登录ActiveMQ管理端

 

5:通过Spring-boot操作ActiveMQ JMS

(1)通过gradle构建Spring-boot应用,在 gradle文件中增加

dependencies {
    compile('org.springframework.boot:spring-boot-starter-activemq')
    compile('org.springframework.boot:spring-boot-starter-web')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

(2)application中增加以下配置

spring.activemq.broker-url=failover:(tcp://192.168.3.10:61616,tcp://192.168.3.11:61616,tcp://192.168.3.12:61616)
spring.activemq.in-memory=true
spring.activemq.pool.enabled=false
spring.activemq.user=admin
spring.activemq.password=admin

(3)JMS消息发送

@Service
public class Producer {

    @Autowired
    private JmsMessagingTemplate jmsTemplate;

    public void sendMessage(Destination destination, final String message){
        jmsTemplate.convertAndSend(destination, message);
    }
}

(4)JMS消息接收

@Component
public class Consumer {
    @JmsListener(destination = "test.queue")
    public void receiveQueue(String text){

        System.out.println("Consumer收到的报文为:"+text);
    }
}

(5)测试

@RestController
@RequestMapping(
        value = "/test",
        headers = "Accept=application/json",
        produces = "application/json;charset=utf-8"
)
public class TestCtrl {
    @Autowired
    Producer producer;

    Destination destination = new ActiveMQQueue("test.queue");

    @RequestMapping(
            value = "/say/{msg}/to/{name}",
            method = RequestMethod.GET
    )
    public Map<String, Object> say(@PathVariable String msg, @PathVariable String name){
        Map<String, Object> map = new HashMap<>();
        map.put("msg", msg);
        map.put("name", name);

        producer.sendMessage(destination, msg);

        return map;
    }
}

(6)进入ActiveMQ管理控制台创建一个消息队列

test.queue

(7)通过POSTMAN进行测试

2017-08-03 08:10:44.928 INFO 12820 --- [ActiveMQ Task-3] o.a.a.t.failover.FailoverTransport : Successfully reconnected to tcp://192.168.3.10:61616
2017-08-03 08:11:08.854 INFO 12820 --- [ActiveMQ Task-1] o.a.a.t.failover.FailoverTransport : Successfully connected to tcp://192.168.3.10:61616
Consumer收到的报文为:hello
2017-08-03 08:43:39.464 INFO 12820 --- [ActiveMQ Task-1] o.a.a.t.failover.FailoverTransport : Successfully connected to tcp://192.168.3.10:61616
Consumer收到的报文为:hello

(8)目前系统连接的是10,如果此时将10集群Down掉,系统会理解选择一台slave作为master提供服务,从而启动案例主备的效果。
