RocketMQ源码阅读（1）-环境搭建

1、rocketmq源码导入

jdk/maven安装配置略，源码地址：

https://github.com/apache/rocketmq.git

2、项目启动

2.1、NameServer启动

1)找到NamesrvStartup主类

2）配置环境变量（ROCKETMQ_HOME=d:\rocketmq）

3）创建相应目录（d:\rocketmq，并在该目录下创建conf、logs、store目录）

4）、拷贝相应配置文件（distribution：broker.conf、logback_broker.xml、logback_broker.xml）到D:\rocketmq\conf目录下，修改修改logback_broker.xml文件的日志路径，broker.conf文件部分配置

brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH

# nameServer地址，分号分割
namesrvAddr=127.0.0.1:9876

# 存储路径
storePathRootDir=D:\\rocketmq\\store

# commitLog 存储路径
storePathCommitLog=D:\\rocketmq\\store\\commitlog

# 消费队列存储路径
storePathConsumeQueue=D:\\rocketmq\\store\\consumequeue

# 消息索引存储路径
storePathIndex=D:\\rocketmq\\store\\index

# checkpoint 存储路径
storeCheckpoint=D:\\rocketmq\\store\\checkpoint

# abort文件存储路径
abortFile=D:\\rocketmq\\store\\abort

5）、运行NamesrvStartup主类

 

2.2、Broker启动

1）、配置启动参数

2）、运行BrokerStartup主类

2.3、测试消息发送与消息消费

1）、发送消息：org.apache.rocketmq.example.quickstart.Producer

    设置NameServer地址：

producer.setNamesrvAddr("127.0.0.1:9876");

   然后运行该类的main方法,有如下响应证明消息发送成功：

SendResult [sendStatus=SEND_OK, msgId=C0A8008149AC18B4AAC2189669D503E7, offsetMsgId=C0A8380100002A9F000000000002E11D, messageQueue=MessageQueue [topic=TopicTest, brokerName=broker-a, queueId=0], queueOffset=249]

2）、消费者消费消息：org.apache.rocketmq.example.quickstart.Consumer

 设置NameServer地址：

consumer.setNamesrvAddr("127.0.0.1:9876");

然后运行该类的main方法，有如下响应证明消息消费成功：

ConsumeMessageThread_12 Receive New Messages: [MessageExt [queueId=1, storeSize=189, queueOffset=239, sysFlag=0, bornTimestamp=1567679710658, bornHost=/192.168.56.1:55552, storeTimestamp=1567679710658, storeHost=/192.168.56.1:10911, msgId=C0A8380100002A9F000000000002C15E, commitLogOffset=180574, bodyCRC=730101603, reconsumeTimes=0, preparedTransactionOffset=0, toString()=Message{topic='TopicTest', flag=0, properties={MIN_OFFSET=0, MAX_OFFSET=250, CONSUME_START_TIME=1567680098005, UNIQ_KEY=C0A8008149AC18B4AAC2189669C203BC, WAIT=true, TAGS=TagA}, body=[80, 114, 111, 100, 117, 99, 101, 114, 45, 72, 101, 108, 108, 111, 32, 82, 111, 99, 107, 101, 116, 77, 81, 32, 57, 53, 54], transactionId='null'}]]
