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
