RockerMq集群部署及简单使用

RockerMq分布式存储架构

Name Server
- NameServer是RockerMQ的寻址服务，用于聚合和管理Broker的路由信息，客户端持有Topic通过NameServer获取对应的Broker路由信息，从而与其Broker做连接
- NameServer集群本身没有状态，各NameServer节点也不做通信，仅提供负载均衡效果
- NamsServer通过Broker上报状态将Broker路由清单存储至内存中（类似于Eureka）
- 如果NameServer服务都停止了，仅会影响路由的更新，而如果客户端已和Broker做了长连接，则不会被影响之间的通信
Broker节点
- 是消息存储、消费和转发的服务器
- Broker集群通过Group进行组区分，每个组有一个Master节点和若干个Slave节点，其中只有Master具有写操作
- Slave会从Master同步数据，同步策略由Master配置决定，可采用同步双写和异步复制两种
- 客户端默认从Master中消费数据，如果NameServer感知Broker挂机后，则会从Slave中消费
- Broker会和所有NameServer节点做长连接，并注册Topic信息

RockerMq集群部署

注意：本次部署通过docker-compose一台机部署，生产环境可分开

mkdir -p nameserver/{nameserver1,nameserver2}/{logs,store}

mkdir -p broker/{broker-master,broker-salve1,broker-salve2}/{logs,store,conf}

编写主节点配置文件：vi broker/broker-master/conf/broker.conf

#集群名称
brokerClusterName=DefaultCluster
#broker名称
brokerName=broker-master
#对外网暴露的IP地址，brokerIP1是外界访问IP，brokerIP2是Slave同步master所使用的，如果是从节点配置，则不需要brokerIP2
brokerIP1=192.168.142.31
brokerIP2=192.168.142.31
# broker节点Id，0是主节点
brokerId=0
#默认的Topic队列数
defaultTopicQueueNums=4
#自动创建Topic，建议线上关闭，线下开启
autoCreateTopicEnable=true
#自动创建订阅组，建议线上关闭，线下开启
autoCreateSubscriptionGroup=true
#broker对外服务监听端口
listenPort=10911
#默认0时删除文件
deleteWhen=00
#文件保留120小时
fileReservedTime=120
#commitLog default size=1G
#mapedFileSizeCommitLog=1073741824
#ConsumeQueue per file=30W
#mapedFileSizeConsumeQueue=300000
#destroyMapedFileIntervalForcibly=120000
#redeleteHangedFileInterval=120000
#物理磁盘最大利用百分比，超过则报警
#diskMaxUsedSpaceRatio=88
#store path
storePathRootDir=/home/rocketmq/store
#commitLog path
storePathCommitLog=/home/rocketmq/store/commitlog
#consumer path
storePathConsumeQueue=/home/rocketmq/store/consumequeue
#index path
storePathIndex=/home/rocketmq/store/store/index
#checkpoint file path
storeCheckpoint=/home/rocketmq/store/checkpoint
#abort path

maxMessageSize=65536
#flushCommitLogLeastPages=4
#flushConsumeQueueLeastPages=2
#flushCommitLogThoroughInterval=10000
#flushConsumeQueueThoroughInterval=60000
# Broker role 
#-ASYNC_MASTER 异步复制Master   - SYNC_MASTER 同步双写Master
# 从节点的话：brokerRole=SLAVE
brokerRole=SYNC_MASTER
flushDiskType=SYNC_FLUSH
#checkTransactionMessageEnable=false
#sendMessageThreadPoolNums=128
#pullMessageThreadPoolNums=128
#磁盘满、且无过期文件情况下 TRUE 表示强制删除文件,优先保证服务可用;FALSE 标记服务不可用,文件 不删除 
cleanFileForciblyEnable=true

将配置文件拷贝到从节点中
- 修改节点名称：brokerName
- 修改节点ID：brokerId
- 去掉BrokerIP2配置（此配置是master提供给slave同步用的）
- 修改节点Role：brokerRole=SLAVE

cp broker/broker-master/conf/broker.conf broker/broker-salve1/conf/broker.conf;
cp broker/broker-master/conf/broker.conf broker/broker-salve2/conf/broker.conf

编写启动docker-compose配置文件：vi docker-compose.yml

        String producerGroup = "my-rmq-group";
        String namesrvAddr = "192.168.142.31:9876;192.168.142.31:9877;";

            Message message = new Message(topic, tags, body.getBytes());
            // 使用生产者生产信息
            SendResult sendResult = producer.send(message);
            System.out.println(sendResult);

        consumer.setNamesrvAddr(namesrvAddr);
        consumer.setInstanceName(consumerName);
        consumer.subscribe(topic, tags);
        // 事件监听器
        consumer.registerMessageListener((MessageListenerConcurrently) (list, consumeConcurrentlyContext) -> {
            for (MessageExt msg : list) {
                System.out.println("消费的消息：" + msg.getMsgId() + "，消息内容：" + new String(msg.getBody()));
            }
            return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
        });
        consumer.start();
        System.out.println("Rocket消费者客户端启动……");
    }
}
