由于apache 官网的 docker image 是单点，要实现集群方式部署。

rocketmq 分为 nameserver 和 broker ，对于之间调用频繁的服务，会增加网络压力，所以考虑又网络通信变成进程间通信，那么1个pod 中包含两个container。

关于rocketmq 下载编译， https://www.cnblogs.com/fengjian2016/p/10150394.html

拿到编译后的 apache-rocketmq , 需要修改一些配置，例如：

1. rm -rf  删除 rocketmq/bin/*.cmd

2 .把runserver.sh  HEAP_OPTS 变成环境变量， 把runbroker.sh  HEAP_OPTS 变成环境变量


3. 指定消息存储路径

[root@rocketmq1 conf]#mkdir -p /data/rocketmq/store
[root@rocketmq1 conf]#mkdir -p /data/rocketmq/store/commitlog
[root@rocketmq1 conf]#mkdir -p /data/rocketmq/logs

4. 指定日志输出路径

/data/rocketmq/conf/ 中的xml文件
sed -i 's#${user.home}#/data/rocketmq/logs#g' *.xml

5. 删除多余配置文件 2m-2s 2master 等等， 启动的时候k8s command 直接指向文件
/data/rocketmq/conf/ 目录下新建 broker-a.conf  broker-b.conf 2个文件

6. 配置修改

　　(1) rocketmqHome 修改

　　(2) namesrvAddr 修改，强调通一个pod 必须写localhost 或者 127.0.0.1 要不然调不通

[root@harbor conf]# cat broker-a.conf
