下载和安装
- 下载 RocketMQ
从这里下载：https://github.com/alibaba/RocketMQ/releases，当前版本标签为 3.5.8
$ ls
RocketMQ-3.5.8RocketMQ-3.5.8.tar.gz
- 安装
$ pwd
/Users/houbinbin/it/tools/rocketMQ/RocketMQ-3.5.8
$ bash install.sh
...
然后我们得到
To refactor, move this assembly into a child project and use the flag <useAllReactorProjects>true</useAllReactorProjects> in each moduleSet.

环境配置
确保以下环境变量正确设置：JAVA_HOME
现在设置 ROCKETMQ_HOME 环境变量：
cd devenv
echo "ROCKETMQ_HOME=`pwd`" >> ~/.bash_profile
立即生效：
source ~/.bash_profile
启动 RocketMQ Name Server 和 Broker
确保在 devenv 目录下：
$ cd bin
$ pwd
/Users/houbinbin/it/tools/rocketMQ/RocketMQ-3.5.8/devenv/bin
- 启动 Name Server
screen bash mqnamesrv
现实是可能会遇到这个:
$ screen bash mqnamesrv
[screen is terminating]
执行以下命令(暂时提权):
su
使用 screen 命令进入, 运行:
$ bash mqnamesrv
接下来
sh-3.2# bash mqnamesrv

The Name Server boot success. serializeType=JSON
如果您看到 "The Name Server boot success. serializeType=JSON"，这表示命名服务器已成功启动。
按下 Ctrl + A，然后按 D 分离会话。

The broker[houbinbindeMacBook-Pro.local, 192.168.2.102:10911] boot success. serializeType=JSON and name server is localhost:9876
如果您看到类似以下输出：
The broker[lizhanhui-Lenovo, 172.30.30.233:10911] boot success. serializeType=JSON and name server is localhost:9876，则您的 broker 已成功运行。
发送和接收消息
在发送/接收消息之前，我们需要告诉客户端名称服务器的位置。RocketMQ 提供了多种实现方式。
为简单起见，我们使用环境变量 NAMESRV_ADDR。
$ export NAMESRV_ADDR=localhost:9876
