mqtt 记录（emqx作为服务器）

20190929

（1）搞了差不多两天吧

STM32当客户端

然后找服务器。看了个各个服务器比较的文章，里面有个emqtt感觉功能挺全的。找了emqx-windows-v3.2.3下载下来。然后安装。

也没记下来看了哪个网站的文章，反正很简单，就是一句启动指令 。

F:\emqx-windows-v3.2.3>cd emqx

F:\emqx-windows-v3.2.3\emqx>bin
'bin' 不是内部或外部命令，也不是可运行的程序
或批处理文件。

F:\emqx-windows-v3.2.3\emqx>cd bin

F:\emqx-windows-v3.2.3\emqx\bin>
F:\emqx-windows-v3.2.3\emqx\bin>emqx start

F:\emqx-windows-v3.2.3\emqx>
 

然后串口打印显示：

电脑当作服务器显示：

 

也看不懂都是什么。反正意思是能通讯上了！慢慢熟悉吧！

20200319 今天又搞了一把，竟然不会弄了，于是参考这个网站，https://blog.youkuaiyun.com/qq_38422317/article/details/103685011，包括用户名 密码 启动mqtt

--

20200323 刚才又试了一下，又不会弄了。

总结一下：

（1）从官网下载https://packages.emqx.io/emqx-ce/v4.0.5/emqx-windows-v4.0.5.zip

（2）解压到F盘，我是WIN10系统，在bin文件夹里面 按SHIFT 和 鼠标右键，在出现的菜单里面，如下：

然后再弹出的界面输入  ./emqx start

如下：

然后打开浏览器输入  127.0.0.1:18083

然后用户名是 admin  密码是public
