docker安装RocketMQ的实现步骤

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:%s\n",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:%s\n",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

http://192.168.23.131:8180/

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
