【原创】《从0开始学RocketMQ》—集群搭建

琳茹的技术轮子 2019-01-21 19:43:00 阅读数:363 评论数:0 点赞数:0 收藏数:0

用两台服务器,搭建出一个双master双slave、无单点故障的高可用 RocketMQ 集群。此处假设两台服务器的物理 IP 分别为:192.168.50.1、192.168.50.2。

内容目录

1. 启动 NameServer 集群

2. 启动 Broker 集群

3. RocketMQ 可视化管理控制台:rocketmq-console

4. 集群测试

 

1. 启动 NameServer 集群

在两台服务器上分别启动 NameServer,可以得到一个无单点故障的 NameServer 服务,服务地址分别为:192.168.50.1:9876、192.168.50.2:9876。

 

2. 启动 Broker 集群

修改 Broker 配置文件,以使每台服务器上都可以启动一个 Master 角色 的 Broker 和 一个Slave 角色的 Broker。
首先找到 Broker 配置文件,此处我们搭建一个同步双写模式的集群,所以需要修改 2m-2s-sync 目录下的 broker 配置文件:

[root@157-89 ~]# cd /usr/local/rocketmq-all-4.3.2-bin-release/conf/
[root@157-89 conf]# ls
2m-2s-async 2m-2s-sync 2m-noslave broker.conf logback_broker.xml logback_namesrv.xml logback_tools.xml
[root@157-89 conf]# cd 2m-2s-sync/
[root@157-89 2m-2s-sync]# ls
broker-a.properties broker-a-s.properties broker-b.properties broker-b-s.properties

1) 修改 192.168.50.1 服务器上的 broker-a.properties 为 Master 角色的 Broker:

namesrvAddr=192.168.50.1:9876;192.168.50.2:9876
brokerClusterName=rocketMqCluster
brokerIP1=192.168.50.1
brokerName=broker-a
brokerId=0
deleteWhen=04
fileReservedTime=120
mapedFileSizeConsumeQueue=500000
brokerRole=SYNC_MASTER
flushDiskType=ASYNC_FLUSH
listenPort=10911
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
storePathRootDir=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a
storePathCommitLog=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a/commitlog
storePathConsumeQueue=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a/consumequeue
storePathIndex=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a/index
storeCheckpoint=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a/checkpoint
abortFile=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a/abort

2) 修改 192.168.50.2 服务器上的 broker-b.properties 为 Master 角色的 Broker:

namesrvAddr=192.168.50.1:9876;192.168.50.2:9876
brokerClusterName=rocketMqCluster
brokerIP1=192.168.50.2
brokerName=broker-b
brokerId=0
deleteWhen=04
fileReservedTime=120
mapedFileSizeConsumeQueue=500000
brokerRole=SYNC_MASTER
flushDiskType=ASYNC_FLUSH
listenPort=10911
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
storePathRootDir=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b
storePathCommitLog=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b/commitlog
storePathConsumeQueue=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b/consumequeue
storePathIndex=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b/index
storeCheckpoint=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b/checkpoint
abortFile=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b/abort

3) 修改 192.168.50.1 服务器上的 broker-b-s.properties 为 Slave 角色的 Broker:

namesrvAddr=192.168.50.1:9876;192.168.50.2:9876
brokerClusterName=rocketMqCluster
brokerIP1=192.168.50.1
brokerName=broker-b
brokerId=1
deleteWhen=04
fileReservedTime=120
mapedFileSizeConsumeQueue=500000
brokerRole=SLAVE
flushDiskType=ASYNC_FLUSH
listenPort=10921
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
storePathRootDir=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s
storePathCommitLog=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s/commitlog
storePathConsumeQueue=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s/consumequeue
storePathIndex=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s/index
storeCheckpoint=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s/checkpoint
abortFile=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-b-s/abort

4) 修改 192.168.50.2 服务器上的 broker-a-s.properties 为 Slave 角色的 Broker:

namesrvAddr=192.168.50.1:9876;192.168.50.2:9876
brokerClusterName=rocketMqCluster
brokerIP1=192.168.50.2
brokerName=broker-a
brokerId=1
deleteWhen=04
fileReservedTime=48
brokerRole=SLAVE
flushDiskType=ASYNC_FLUSH
listenPort=10921
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
storePathRootDir=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s
storePathCommitLog=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s/commitlog
storePathConsumeQueue=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s/consumequeue
storePathIndex=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s/index
storeCheckpoint=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s/checkpoint
abortFile=/usr/local/rocketmq-all-4.3.2-bin-release/data/broker-a-s/abort

一台服务器上启动多个Broker 时,需指定不同的端口号,记得防火墙放开 NameServer 和 Broker 中用到的端口号哦~

分别启动四个 Broker:

nohup sh bin/mqbroker -c broker_config_file &

 

3. RocketMQ 可视化管理控制台:rocketmq-console

在服务器 192.168.50.1 上安装即可,无需集群

[root@153-215 rocketmq-externals]# vim rocketmq-console/src/main/resources/application.properties 

编辑 application.properties:

server.contextPath=/rocketmq
server.port=8080
#spring.application.index=true
spring.application.name=rocketmq-console
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true

#if this value is empty,use env value rocketmq.config.namesrvAddr NAMESRV_ADDR | now, you can set it in ops page.default localhost:9876
rocketmq.config.namesrvAddr=192.168.50.1:9876;192.168.50.2:9876
#if you use rocketmq version < 3.5.8, rocketmq.config.isVIPChannel should be false.default true
rocketmq.config.isVIPChannel=
#rocketmq-console's data path:dashboard/monitor
rocketmq.config.dataPath=/tmp/rocketmq-console/data
#set it false if you don't want use dashboard.default true
rocketmq.config.enableDashBoardCollect=true

移动 rocketmq-console 所在目录,编译并启动 rocketmq-console:

[root@153-215 rocketmq-console]# mv /usr/local/rocketmq-externals/rocketmq-console /usr/local/rocketmq-console

4. 集群测试

Producer 测试代码:

public class SyncProducerTest {
public static void main(String[] args) {
DefaultMQProducer producer = new DefaultMQProducer("producer_test_group");
producer.setNamesrvAddr("39.107.153.215:9876;39.107.157.89:9876");
try{
producer.start();
for(int i=0;i<100;i++){
Message message = new Message("topic_test", "tag_test", ("Hello World" + 1).getBytes("UTF-8"));
SendResult sendResult = producer.send(message);
System.out.println(JSON.toJSON(sendResult));
}
producer.shutdown();
}catch (Exception e){
e.printStackTrace();
}
}
}

Consumer 测试代码:

public class SyncConsumerTest {
public static void main(String[] args) {
DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("consumer_test_group");
consumer.setNamesrvAddr("39.107.153.215:9876;39.107.157.89:9876");
consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);
try {
consumer.subscribe("topic_test", "*");
consumer.registerMessageListener((MessageListenerConcurrently) (messageList, context) -> {
System.out.println(Thread.currentThread().getName() + " Receive New Message:" + messageList);
return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
});
consumer.start();
}catch (Exception e){
e.printStackTrace();
}
}
}

SyncProducerTest 运行日志:

SyncConsumerTest 运行日志:

通过日志可以看到,消费者、生产者收发消息都是正常的,我们去可视化管理控制台查看下 http://192.168.50.1:8080/rocketmq:

通过管控台可以看到,双 master 双 slave 的 broker 集群一切正常,并可进一步看到每个 broker 处理消息的情况。
