1.软件的选型
1.1.使用免费版EMQX
1.1.1.下载
百度搜索的目前是会打开官网，这里提供下免费版的使用链接EMQX使用手册
文档很详细，这里不再记录了。
1.2.使用rabbitmq
rabbitmq一般做消息队列用，作为mqtt用我没有找到详细资料，这里总结下使用方法：
1.window安装rabbitmq
首先安装rabbitmq得依赖，也就是opt_win64_24.0.exe,然后傻瓜式安装接可
安装完毕，进入安装目录下，sbin文件夹
1.浏览器查看插件 执行命令
rabbitmq-plugins enable rabbitmq_management
回车，浏览器输入http://127.0.0.1:15672/#/看到此页面及安装成功，默认账号密码均是 guest
2.注意：如果做mqtt使用的话，需安装mqtt插件 安装命令
rabbitmq-plugins enable rabbitmq_mqtt
执行完命令，在浏览器上查看 mqtt及其端口号出现了的话，就证明安装成功，下面就可以开始整合了
2.linux安装rabbitmq
以前公司都是用window服务器，没用过linux，折腾了好久，安装 erlang与rabbitmq不对应 不是最新 等等一系列问题，最后看了一个视频 用 dock安装 根据官网
docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management
一句话就可以安装
如果后期需要安装插件
docker exec <容器id> rabbitmq-plugins enable rabbitmq_mqtt
ps:查看容器id 方法
1.使用docker ps -aqf “name=containername” -------简短容器id
2.docker inspect --format="{{.Id}}" container_name -------详情容器id
带密码启动dock
docker run -it --rm --name rabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=密码 -p 15672:15672 -p 5672:5672 -p 1883:1883 rabbitmq:management
15672 是rabbitmq management管理界面默认访问端口
5672 是amqp默认端口
1883 是mqtt tcp协议默认端口
15675 是web_mqtt ws协议默认端口
2.springboot集成mqtt
