1.5 启动容器以复制配置文件

1.5.1 启动NamerServer容器

docker run -d \
--privileged=true \
--name testnameserver \
apache/rocketmq:5.1.0 sh mqnamesrv

1.5.2 复制NameServer启动脚本

docker cp testnameserver:/home/rocketmq/rocketmq-5.1.0/bin/runserver.sh /home/rocketmq/nameserver/bin/runserver.sh

1.5.3 修改脚本文件

vim /home/rocketmq/nameserver/bin/runserver.sh

# 注释该行
calculate_heap_sizes

1.5.4 停止并删除NameServer容器

docker stop testnameserver

docker rm testnameserver

1.5.5 启动Broker容器

docker run -d \
--name testbroker \
--privileged=true \
apache/rocketmq:5.1.0 \
sh mqbroker

1.5.6 复制Broker启动脚本

docker cp testbroker:/home/rocketmq/rocketmq-5.1.0/bin/runbroker.sh /home/rocketmq/broker/bin/runbroker.sh

1.5.7 修改脚本文件

vim /home/rocketmq/broker/bin/runbroker.sh

# 注释该行
calculate_heap_sizes

1.5.8 停止并删除Broker容器

docker stop testbroker

docker rm testbroker

1.6 创建broker.conf配置文件

vim /home/rocketmq/broker/conf/broker.conf

# 你的NameServer服务器公网IP地址与端口号
namesrvAddr=127.0.0.1:9876
# 集群名称
brokerClusterName = DefaultCluster
# 节点名称
brokerName = broker-a
# broker id节点ID， 0 表示 master, 其他的正整数表示 slave，不能小于0 
brokerId = 0
# Broker服务地址（你的服务器公网IP地址）
brokerIP1 = 127.0.0.1
# Broker角色
brokerRole = ASYNC_MASTER
# 刷盘方式
flushDiskType = ASYNC_FLUSH
# 删除时间（4点）
deleteWhen = 04
# 文件保留时间（72小时）
fileReservedTime = 72
# 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
# 检测可用的磁盘空间大小，超过后会写入报错（95%）
diskMaxUsedSpaceRatio=95

1.7 文件夹赋权

chmod -R 777 /home/rocketmq/

1.8 启动容器

1.8.1 启动NameServer容器

docker run -d \
--privileged=true \
--restart=always \
--name nameserver \
-p 9876:9876  \
-v /home/rocketmq/nameserver/logs:/home/rocketmq/logs \
-v /home/rocketmq/nameserver/bin/runserver.sh:/home/rocketmq/rocketmq-5.1.0/bin/runserver.sh \
-e "MAX_HEAP_SIZE=256M" \
-e "HEAP_NEWSIZE=128M" \
-e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m -Xmn128m" \
apache/rocketmq:5.1.0 sh mqnamesrv

1.8.2 启动Broker容器

docker run -d \
--restart=always \
--name broker  \
-p 10911:10911 -p 10909:10909 \
--privileged=true \
-v /home/rocketmq/broker/logs:/root/logs \
-v /home/rocketmq/broker/store:/root/store \
-v /home/rocketmq/broker/conf/broker.conf:/home/rocketmq/broker.conf \
-v /home/rocketmq/broker/bin/runbroker.sh:/home/rocketmq/rocketmq-5.1.0/bin/runbroker.sh \
-e "MAX_HEAP_SIZE=512M" \
-e "HEAP_NEWSIZE=256M" \
-e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m -Xmn128m" \
apache/rocketmq:5.1.0 \
sh mqbroker -c /home/rocketmq/broker.conf

1.9 查看当前容器

docker ps

2 部署RocketMQ可视化控制台

2.1 查看镜像

docker search apacherocketmq/rocketmq-dashboard

2.2 拉取镜像（默认最新版本）

docker pull apacherocketmq/rocketmq-dashboard

2.3 启动容器

# 你的NameServer服务器公网IP地址与端口号
docker run -d \
--restart=always \
--name dashboard \
-e "JAVA_OPTS=-Xmx256M -Xms256M -Xmn128M -Drocketmq.namesrv.addr=127.0.0.1:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false" \
-p 8082:8080 \
apacherocketmq/rocketmq-dashboard

2.4 查看当前容器

docker ps

3 开放对应端口

4 访问可视化控制台

# 你的服务器公网IP地址
http://127.0.0.1:8082/

三、代码测试

1 根据项目信息搭建完成模块

2 补充配置信息（由于SpringBoot3.0以上版本所引发）

2.1 在resource下创建META-INF文件夹

2.2 在META-INF文件夹下创建spring文件夹

2.3 创建文件

# 文件名信息
org.springframework.boot.autoconfigure.AutoConfiguration.imports

# 文件内容
org.apache.rocketmq.spring.autoconfigure.RocketMQAutoConfiguration

3 创建消息发送测试类

package com.catalpa.study.test;
 
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class OrderController {
 
    @Autowired
    private RocketMQTemplate rocketMQTemplate;
 
    @RequestMapping("/test")
    public String order() {
        String test = "123测试";
        rocketMQTemplate.convertAndSend("ORDER_TOPIC", test);
        return test;
    }
}

4 创建消费测试类

package com.catalpa.study.listener;

import org.apache.rocketmq.spring.annotation.ConsumeMode;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Service;

@Service
@RocketMQMessageListener(topic = "ORDER_TOPIC", consumerGroup = "BREAD_ORDER_GROUP", consumeMode = ConsumeMode.ORDERLY)
public class NormalRocketMqListener implements RocketMQListener<String> {
    @Override
    public void onMessage(String s) {
        System.out.println("普通订阅-接收到的信息：{}"+ s);
    }
}

5 测试

5.1 启动项目

5.2 访问消息发送测试接口

http://127.0.0.1:8081/test

5.3 测试成功
