rocketmq安装使用教程
rocketmq安装使用教程
本文假设您已经完成了下列前序步骤：
- docker安装配置
一、docker安装rokcetmq
1.1 安装namesrv
docker pull rocketmqinc/rocketmq:latest
/**
- 安装namesrv
- -d # 后台运行
- -p #设置默认端口，这里rocketmq默认9876端口
- -v #设置映射本地目录到容器内的目录，这个注意我都是把本地 的/usr/local/docker/rocketmq/**映射到容器内的对应目录的，这个可以改成你本地的linux目录，当然也可以和我一样。我理解的就是MQ的数据和日志什么的不能放在容器中啊，因为容器毕竟占用的空间有限，就映射一下放在本地目录中。
*/
docker run -d -p 9876:9876 -v /usr/local/docker/rocketmq/data/namesrv/logs:/root/logs -v /usr/local/docker/rocketmq/data/namesrv/store:/root/store --name rmqnamesrv -e "MAX_POSSIBLE_HEAP=100000000" rocketmqinc/rocketmq:latest sh mqnamesrv
1.2 安装 broker
创建broker配置文件(路径不存在就创建路径)：
mkdir -p /usr/local/docker/rocketmq/conf
vi /usr/local/docker/rocketmq/conf/broker.conf
------------------------------------------------------------------
brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
brokerIP1 = 39.96.46.193
------------------------------------------------------------------
- 用broker.conf配置启动容器
docker run -d -p 10911:10911 -p 10909:10909 -v /usr/local/docker/rocketmq/data/broker/logs:/root/logs -v /usr/local/docker/rocketmq/data/broker/store:/root/store -v /usr/local/docker/rocketmq/conf/broker.conf:/opt/rocketmq-latest/conf/broker.conf --name rmqbroker --link rmqnamesrv:namesrv -e "NAMESRV_ADDR=namesrv:9876" -e "MAX_POSSIBLE_HEAP=200000000" rocketmqinc/rocketmq:latest sh mqbroker -c /opt/rocketmq-latest/conf/broker.conf
1.3 安装 rocketmq 控制台
- 拉取镜像
docker pull pangliang/rocketmq-console-ng
- 后台启动
docker run -d -e "JAVA_OPTS=-Drocketmq.namesrv.addr=39.96.46.193:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false" -p 8080:8080 -t pangliang/rocketmq-console-ng
- 检查镜像启动情况
docker ps -a
注意注意：一定要开启防火墙的相应端口
通过看上面的配置需要开启9876、10911、10909、18080四个端口号
1.4 查看web控制台
打开浏览器访问39.96.46.193:8080 注意访问你linux的ip和上面rocketmq控制台映射的8080端口。
这里就不过多介绍控制台的使用了，想了解的可以自己查找资料。
二、rocketmq代码使用
2.1 springboot整合rocketmq
- pom.xml
<dependency>
<groupId>org.apache.rocketmq</groupId>
<artifactId>rocketmq-spring-boot-starter</artifactId>
<version>2.0.4</version>
</dependency>
- application.yml
#name-server
rocketmq:
name-server: 39.96.46.193:9876
producer:
group: mygroup
myrocketmq-config:
my-topic: my_topic
my-consumer-group: my_consumer_group
- 生产者

SendResult sendResult = rocketMQTemplate.syncSendOrderly(my_topic+ ":hld-tag", msg,"hld");

System.out.println("同步发送字符串: " + msg + "至topic: "+my_topic+",发送结果: " + sendResult);
}
//异步发送
@GetMapping("/async")
public void async(){
//生产消息 topic:tag ,消息内容 ,回调函数
rocketMQTemplate.asyncSend("test", "Hello world!", new SendCallback() {
@Override
public void onSuccess(SendResult var1) {
System.out.println("异步发送成功: "+ var1);
}
@Override
public void onException(Throwable var1) {
System.out.println("异步发送失败: "+ var1);

}

@GetMapping("/oneway")
public void oneway(){
//生产消息 topic:tag ,消息内容 没有返回结果
rocketMQTemplate.sendOneWay("test", "Hello world!");
System.out.println("单向发送");
}
}
- 消费者
/**
* consumerGroup:消费组（一个ConsumerGroup中的Consumer实例平均分摊消费消息）
* topic ：主题
* selectorExpression：tag（消费哪个tag的消息）
*/
@Component
@Slf4j
@RocketMQMessageListener(consumerGroup = "${myrocketmq-config.my-consumer-group}", topic = "${myrocketmq-config.my-topic}"
,selectorExpression= "hld-tag")
public class MqConsumer implements RocketMQListener<String> {
@Value("${server.port}")
private String port;
@Override
public void onMessage(String message) {
log.info("port:{} consume收到消息:{} ",port,message);
}
}
如果想要启动多个消费者可以idea配置不同端口启动多个服务：
