docker安装rocketMq

在搭建之前，我们需要做一些准备工作，这里我们需要使用 docker 搭建服务，所以需要提前安装 docker。

此外，由于 rocketmq 需要部署 broker 与 nameserver ，考虑到分开部署比较麻烦，这里将会使用docker-compose，如果还未安装docker-compose的可移步至此处：《Docker-Compose安装教程》

1.创建相关配置文件

创建三个目录/conf，/logs，/store，位置随意，自己能够找的到就可以，并在/conf该目录中创建：borker.conf，最后创建 docker-compose.yml 文件
在这里插入图片描述

borker.conf的配置如下：

需要注意：borkerIp1需要写成自己服务的ip
