一 . 在本地电脑上安装emqtt服务器:
1.首先安装补丁:把补丁拷贝到" C:\Windows\System32 "文件夹下
2. 控制台模式下启动:emqttd console
(1) 控制台下切换到emqtt的bin目录下。如：
快速切换方法：在此目录下按住“Shift”同时点击鼠标右键选择“在此处打开 命令窗口”
(2)启动mqtt服务器 “emqttd console”
3. 通过网页登陆查看链接信息 用户名：admin 密码：public
查看本机ip：
链接上一个客户端 我们再启动一个客户端让两个客户端通信 我们在查看下链接的客户端 客户端通信
此种方法会打开一个窗口，关掉窗口emqtt服务也关闭； 让emqtt服务器一直运行的 （1）控制台先定位到emqtt的bin目录下“D:\MqttServer\emqttd\bin” （2）emqttd install （3）启动emqttd服务：emqttd start （4）停止emqttd服务：emqttd stop （5）卸载emqttd服务：emqttd uninstall
二. ESP8266 模块连接emqtt服务器进行远程控制
init.lua文件: - RELAY_Pin = 1
- gpio.mode(RELAY_Pin, gpio.OUTPUT)
- gpio.write(RELAY_Pin,0)
- tmr.alarm(0,4000,0,function()
- dofile("mqtt.lua")
- end)

- end)
- uart.on("data",0,function(data)
- UartReceData = UartReceData..data
- UartReceCnt = UartReceCnt + 1
- end,0)
- printip = 0
- wifi.eventmon.register(wifi.eventmon.STA_DISCONNECTED, function(T)

mqtt.lua文件结束
模块通过串口发送数据
PC客户端发送”open”开继电器
PC客户端发送”close”关继电器
