RocketMQ安装与demo

服务器设置

1. 安装64位JDK；

2. 设置Linux文件系统为Ext4

3.开启9876，10911防火墙端口

源码编码

1. 安装Maven 2. 下载RocketMQ源码，下载地址：http://github.com/alibaba/RocketMQ.git/trunk，进入到源码解压目录下运行install.bat或DOS命令行切换到解压目录运行： mvn -Dmaven.test.skip=true clean package install assembly:assembly -U，编译成功后，在target目录下会有alibaba-rocketmq-3.1.1.tar.gz，该压缩包就是安装包。

3. 安装

将alibaba-rocketmq-3.1.1.tar.gz上传到linux服务器，解压：tar -zxvf

alibaba-rocketmq-3.1.1.tar.gz设置执行权限chmod +x ./alibaba-rocketmq/bin/*

4. 运行

配置采用双Master，双Slave，异步复制的配置方式，共需要4台服务器做硬件支持。 a. 修改配置

（1）创建目录

mkdir /home/rocket/alibaba-rocketmq/logs #创建日志目录

mkdir -p /home/rocket/alibaba-rocketmq/data/store/commitlog #创建数据存储目录

更改日志目录

cd /home/rocket/alibaba-rocketmq/conf

（2）修改A主配置

vi ./conf/2m-2s-async/broker-a.properties:

1. # brokerClusterName=DefaultCluster

2. brokerName=broker-a

3. brokerId=0

4. namesrvAddr=192.168.1.119:9876;192.168.1.120:9876;192.168.1.121:9876;1

92.168.1.122:9876

5. defaultTopicQueueNums=4

6. autoCreateTopicEnable=true

7. autoCreateSubscriptionGroup=true

8. listenPort=10911

9. deleteWhen=04

10. fileReservedTime=120

12. mapedFileSizeConsumeQueue=50000000

13. destroyMapedFileIntervalForcibly=120000

14. redeleteHangedFileInterval=120000

15. diskMaxUsedSpaceRatio=88

16. storePathRootDir=/usr/framework/rocketmq/datas

17. storePathCommitLog=/usr/framework/rocketmq/logs

18. maxMessageSize=65536

19. flushCommitLogLeastPages=4

20. flushConsumeQueueLeastPages=2

21. flushCommitLogThoroughInterval=10000

22. flushConsumeQueueThoroughInterval=60000

23. checkTransactionMessageEnable=false

24. sendMessageThreadPoolNums=128

25. pullMessageThreadPoolNums=128

26. brokerRole=SYNC_MASTER

27. flushDiskType=ASYNC_FLUSH
