docker-compose部署RocketMQ

1. 在根目录下创建rocketmq文件夹用来挂载数据 并赋予777权限chmod 777 rocketmq 
   再创建几个子目录 具体如下
   rocketmq/logs
   rocketmq/store
   rocketmq/console
   rocketmq/console/logs
   rocketmq/conf
   rocketmq/conf/broker.conf
   broker.conf文件添加以下内容:
brokerName=broker-a
brokerId=0
deleteWhen=04
fileReservedTime=48
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH
brokerIP1=47.93.156.108   (云服务器外网IP)

2. 在docker-compose.yml中追加rocketmq的namesrv, broker和console三个部分的配置
