RocketMQ的简单使用

一、RocketMQ部署【双Master方式】

1.1、服务器环境

192.168.100.24 root nameServer1,brokerServer1 Master1

192.168.100.25 root nameServer2,brokerServer2 Master2

1.2、Hosts添加信息

192.168.100.24 rocketmq-nameserver1

192.168.100.24 rocketmq-master1

192.168.100.25 rocketmq-nameserver2

192.168.100.25 rocketmq-master2

1.3、上传解压【两台机器】

# 上传alibaba-rocketmq-3.2.6.tar.gz文件至/usr/local

# tar -zxvf alibaba-rocketmq-3.2.6.tar.gz -C /usr/local

# mv alibaba-rocketmq alibaba-rocketmq-3.2.6

# ln -s alibaba-rocketmq-3.2.6 rocketmq

1.4、创建存储路径【两台机器】

# mkdir /usr/local/rocketmq/store

# mkdir /usr/local/rocketmq/store/commitlog

# mkdir /usr/local/rocketmq/store/consumequeue

# mkdir /usr/local/rocketmq/store/index

1.5、RocketMQ配置文件【两台机器】

# vim /usr/local/rocketmq/conf/2m-noslave/broker-a.properties

# vim /usr/local/rocketmq/conf/2m-noslave/broker-b.properties

#所属集群名字
brokerClusterName=rocketmq-cluster
#broker名字，注意此处不同的配置文件填写的不一样
brokerName=broker-a|broker-b
#0 表示 Master，>0 表示 Slave
brokerId=0
#nameServer地址，分号分割
namesrvAddr=rocketmq-nameserver1:9876;rocketmq-nameserver2:9876
#在发送消息时，自动创建服务器不存在的topic，默认创建的队列数
defaultTopicQueueNums=4
#是否允许 Broker 自动创建Topic，建议线下开启，线上关闭
autoCreateTopicEnable=true
#是否允许 Broker 自动创建订阅组，建议线下开启，线上关闭
autoCreateSubscriptionGroup=true
#Broker 对外服务的监听端口
listenPort=10911
#删除文件时间点，默认凌晨 4点
deleteWhen=04
#文件保留时间，默认 48 小时
fileReservedTime=120
#commitLog每个文件的大小默认1G
mapedFileSizeCommitLog=1073741824
#ConsumeQueue每个文件默认存30W条，根据业务情况调整
mapedFileSizeConsumeQueue=300000
#destroyMapedFileIntervalForcibly=120000
#redeleteHangedFileInterval=120000
#检测物理文件磁盘空间
diskMaxUsedSpaceRatio=88
#存储路径
storePathRootDir=/usr/local/rocketmq/store
#commitLog 存储路径
storePathCommitLog=/usr/local/rocketmq/store/commitlog
#消费队列存储路径存储路径
storePathConsumeQueue=/usr/local/rocketmq/store/consumequeue
#消息索引存储路径
storePathIndex=/usr/local/rocketmq/store/index
#checkpoint 文件存储路径
storeCheckpoint=/usr/local/rocketmq/store/checkpoint
#abort 文件存储路径
abortFile=/usr/local/rocketmq/store/abort
#限制的消息大小
maxMessageSize=65536
#flushCommitLogLeastPages=4
#flushConsumeQueueLeastPages=2
#flushCommitLogThoroughInterval=10000
#flushConsumeQueueThoroughInterval=60000
#Broker 的角色
#- ASYNC_MASTER 异步复制Master
#- SYNC_MASTER 同步双写Master
#- SLAVE
brokerRole=ASYNC_MASTER
#刷盘方式
#- ASYNC_FLUSH 异步刷盘
#- SYNC_FLUSH 同步刷盘
flushDiskType=ASYNC_FLUSH
#checkTransactionMessageEnable=false
#发消息线程池数量
#sendMessageThreadPoolNums=128
#拉消息线程池数量
#pullMessageThreadPoolNums=128

1.6、修改日志配置文件【两台机器】

# mkdir -p /usr/local/rocketmq/logs

# cd /usr/local/rocketmq/conf && sed -i ‘s#${user.home}#/usr/local/rocketmq#g’*.xml

1.7、修改启动脚本参数【两台机器】

# vim /usr/local/rocketmq/bin/runbroker.sh

JAVA_OPT=”${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:PermSize=128m -XX:MaxPermSize=320m”

# vim /usr/local/rocketmq/bin/runserver.sh

JAVA_OPT=”${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:PermSize=128m -XX:MaxPermSize=320m”

1.8、启动NameServer【两台机器】

# cd /usr/local/rocketmq/bin

# nohup sh mqnamesrv &

对应的关闭命令是：sh mqshutdown namesrv

1.9、启动BrokerServer A【192.168.100.24】

# cd /usr/local/rocketmq/bin

# nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-a.properties >/dev/null 2>&1 &# netstat -ntlp

# jps

# tail -f -n 500 /usr/local/rocketmq/logs/rocketmqlogs/broker.log

# tail -f -n 500 /usr/local/rocketmq/logs/rocketmqlogs/namesrv.log

1.10、启动BrokerServer B【192.168.100.25】

# cd /usr/local/rocketmq/bin

# nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-b.properties >/dev/null 2>&1 &

# netstat -ntlp

# jps

# tail -f -n 500 /usr/local/rocketmq/logs/rocketmqlogs/broker.log

# tail -f -n 500 /usr/local/rocketmq/logs/rocketmqlogs/namesrv.log

对应的关闭Broker的命令是：sh mqshutdown broker

1.11、部署RocketMQ Console（没有的可以联系我）

1.12、数据清理

# cd /usr/local/rocketmq/bin

# sh mqshutdown broker

# sh mqshutdown namesrv

# –等待停止# rm -rf /usr/local/rocketmq/store

# mkdir /usr/local/rocketmq/store

# mkdir /usr/local/rocketmq/store/commitlog

# mkdir /usr/local/rocketmq/store/consumequeue

# mkdir /usr/local/rocketmq/store/index

# –按照上面步骤重启NameServer与BrokerServer

二、简单示例：

所需jar包(Maven)：

<dependency>
      <groupId>com.alibaba.rocketmq</groupId>
      <artifactId>rocketmq-client</artifactId>
      <version>3.2.6</version>
    </dependency>
    <dependency>
      <groupId>com.alibaba.rocketmq</groupId>
      <artifactId>rocketmq-common</artifactId>
      <version>3.2.6</version>
    </dependency>
    <dependency>
      <groupId>com.alibaba.rocketmq</groupId>
      <artifactId>rocketmq-remoting</artifactId>
      <version>3.2.6</version>
    </dependency>

Producer类：

public class producer {
    public static void main(String[] args) throws MQClientException, RemotingException, InterruptedException, MQBrokerException {
        DefaultMQProducer producer = new DefaultMQProducer("quickstart_producer");
        producer.setNamesrvAddr("192.168.100.24:9876;192.168.100.25:9876");
        producer.start();
        for (int i = 0;i<100;i++){
            Message msg = new Message("TopicQuickStart","TagA",
                    ("Hello RocketMQ" + i).getBytes());
            SendResult sendResult = producer.send(msg);
            System.out.println(sendResult);

        }
    }
}

Consumer类：

public class Consumer {
    public static void main(String[] args) throws MQClientException {
        DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("quickstart_consumer");
        consumer.setNamesrvAddr("192.168.100.24:9876;192.168.100.25:9876");
        consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);

        consumer.subscribe("TopicQuickStart","*");

        consumer.registerMessageListener(new MessageListenerConcurrently() {
            @Override
            public ConsumeConcurrentlyStatus consumeMessage(List<MessageExt> list, ConsumeConcurrentlyContext context) {
                System.out.println(Thread.currentThread().getName() + "Receive New Messages:" + list);
                return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
            }
        });

        consumer.start();

        System.out.println("Consumer Started");
    }

}

三、查看RocketMQ控制台结果：

四、对于2m-2s-async模式的broker启动命令：

# nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-a.properties >/dev/null 2>&1 &

# nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-b.properties >/dev/null 2>&1 &

# nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-a-s.properties >/dev/null 2>&1 &

# nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-b-s.properties >/dev/null 2>&1 &
