docker安装RocketMQ的实现步骤

目录 一、检索镜像 二、创建Broker Server 三、创建broker 四、创建rocketmq console 五、测试 六、java样例 七、其他 参考：

一、检索镜像

docker search rocketmq

检索具体版本

curl https://registry.hub.docker.com/v1/repositories/foxiswho/rocketmq/tags | tr -d [[]” ] | tr } n | awk -F: -v image=foxiswho/rocketmq {if(NR!=NF && $3 != “”){printf(“%s:%sn”,image,$3)}}

查看当前镜像所有的版本shell命令

curl https://registry.hub.docker.com/v1/repositories/foxiswho/rocketmq/tags | tr -d [[]” ] | tr } n | awk -F: -v image=foxiswho/rocketmq {if(NR!=NF && $3 != “”){printf(“%s:%sn”,image,$3)}}

 

二、创建Broker Server

docker run -d -p 9876:9876 –name rmqserver foxiswho/rocketmq:server-4.5.1

 

三、创建broker

docker run -d -p 10911:10911 -p 10909:10909 –name rmqbroker –link rmqserver:namesrv -e “NAMESRV_ADDR=namesrv:9876” -e “JAVA_OPTS=-Duser.home=/opt” -e “JAVA_OPT_EXT=-server -Xms128m -Xmx128m” foxiswho/rocketmq:broker-4.5.1

配置broker.conf

进入rmqbroker容器

docker exec -it rmqbroker /bin/bash cd /etc/rocketmq/ vi broker.conf

四、创建rocketmq console

docker run -d –name rmqconsole -p 8180:8080 –link rmqserver:namesrv -e “JAVA_OPTS=-Drocketmq.namesrv.addr=namesrv:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false” -t styletang/rocketmq-console-ng

然后通过如下命令检查一下启动情况

docker ps|grep rocketmq

五、测试

由于我在宿主机安装rocketmq,测试如下：

#测试消息发送命令 sh tools.sh org.apache.rocketmq.example.quickstart.Producer

#测试消息接收命令 sh tools.sh org.apache.rocketmq.example.quickstart.Consumer

 

六、java样例

<dependency> <groupId>org.apache.rocketmq</groupId> <artifactId>rocketmq-client</artifactId> <version>4.9.2</version> </dependency>

消息发送（Producer端发送同步消息）

import org.apache.rocketmq.client.producer.DefaultMQProducer; import org.apache.rocketmq.client.producer.SendResult; import org.apache.rocketmq.common.message.Message; import org.apache.rocketmq.remoting.common.RemotingHelper; public class SyncProducer { public static void main(String[] args) throws Exception { // 实例化消息生产者Producer DefaultMQProducer producer = new DefaultMQProducer(“zhuzeqing-1”); // 设置NameServer的地址 producer.setNamesrvAddr(“192.168.23.131:9876”); // 启动Producer实例 producer.start(); for (int i = 0; i < 1; i++) { // 创建消息，并指定Topic，Tag和消息体 Message msg = new Message(“zhuzeqing-1-Topic” /* Topic */, “TagA” /* Tag */, (“hello，rocketmq –” + i).getBytes(RemotingHelper.DEFAULT_CHARSET) /* Message body */ ); // 发送消息到一个Broker SendResult sendResult = producer.send(msg); // 通过sendResult返回消息是否成功送达 System.out.printf(“%s%n”, sendResult); } // 如果不再发送消息，关闭Producer实例。 producer.shutdown(); } }

消费消息

import java.util.List; import org.apache.rocketmq.client.consumer.DefaultMQPushConsumer; import org.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyContext; import org.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyStatus; import org.apache.rocketmq.client.consumer.listener.MessageListenerConcurrently; import org.apache.rocketmq.client.exception.MQClientException; import org.apache.rocketmq.common.message.MessageExt; public class Consumer { public static void main(String[] args) throws InterruptedException, MQClientException { // 实例化消费者 DefaultMQPushConsumer consumer = new DefaultMQPushConsumer(“zhuzeqing-1”); // 设置NameServer的地址 consumer.setNamesrvAddr(“192.168.23.131:9876”); // 订阅一个或者多个Topic，以及Tag来过滤需要消费的消息 consumer.subscribe(“zhuzeqing-1-Topic”, “*”); // 注册回调实现类来处理从broker拉取回来的消息 consumer.registerMessageListener(new MessageListenerConcurrently() { public ConsumeConcurrentlyStatus consumeMessage(List<MessageExt> msgs, ConsumeConcurrentlyContext context) { System.out.printf(“%s Receive New Messages: %s %n”, Thread.currentThread().getName(), msgs); // 标记该消息已经被成功消费 return ConsumeConcurrentlyStatus.CONSUME_SUCCESS; } }); // 启动消费者实例 consumer.start(); System.out.printf(“Consumer Started.%n”); } }

七、其他

查看rmqbroker IP

docker inspect rmqbroker

Broker容器中默认的配置文件的路径为

/etc/rocketmq/broker.conf

官网：Apache RocketMQ
