问题 I'm trying to setup a mosquitto broker which is encrypted using ssl/tls. I don't want to generate client certificates. I just want an encrypted connection. The man page only described the settings which are available, not which are needed and how they are used. Which settings are needed and how do you set them? I use mosquitto 1.3.5 回答1: There is a small guide here, but it does not say much: http://mosquitto.org/man/mosquitto-tls-7.html You need to set these: certfile keyfile cafile They can

Is there a way to store Mosquitto payload into an MySQL database for history purpose?

廉价感情. 提交于 2019-11-28 01:25:29
I am using Mosquitto MQTT broker and I would like to store every published message into a MySQL database without creating a client and subscribing to # wildcard. I found this https://github.com/jpmens/mosquitto-auth-plug but my english is not good enough to understand it thoroughly... I think it is only to store persistent message for the broker to resend them later. Am I right ? Thanks The mosquitto-auth-plugin uses the database to store username/password and ACL information, not message content. Writing some code to store messages in a database from any MQTT broker is relatively simple.

Python实现MQTT接收订阅数据

一、背景 目前MQTT的标准组织官网: http://www.mqtt.org ,里面列出了很多支持的软件相关资源。 一个轻量级的MQTT服务器是: http://www.mosquitto.org ,可以运行ARM/MIPS的嵌入式linux系统上。 物联网常使用 “消息队列遥测传输(Message Queuing Telemetry Transport, MQTT)” 协议订阅数据,这里用Python实现从MQTT服务器订阅数据。 首先和TCP协议比较 首先TCP是传输层协议,实现了一个双向的通信链路。 MQTT是基于TCP的应用层协议。(当然中间可能多一层,websocket) 两者不在一个层级,比较谁比谁好是没有意义的。 我们用raw TCP 也可以实现数据通信,比如发送传感器数据到服务器。为什么要用到MQTT呢 ? 假设现在有一个物联网的应用,题主当然可以直接用TCP socket 做通信,实际上不少人也是这么做的。然后你就会发现: 需要自己写确认重传的机制,因为TCP 连接说不定就断了。 如果有很多个传感器(生产者),又要写代码管理这么多TCP连接呢。 如果同时又有多个地方需要用到这些数据,还得写一个转发的逻辑。 如果系统很复杂,参与人或公司很多,那通信格式要怎么定,怎么改,沟通成本就很大了。 这些东西这么麻烦,又不想加班写代码,那有没有办法简便地解决呢?当然有

问题 I'm using mosquitto and the Eclipse PAHO Java client. Everything is working fine on plain TCP sockets. but now I want to use SSL for athentication (encryption not necessarily needed). first I followed the instructions from http://mosquitto.org/man/mosquitto-tls-7.html in mosquitto client I can not publish my message without the --insecure option, means i have to mosquitto_pub -h <server-ip> -p <port> -t "/topic1/test" -m "testmsg" --cafile ca_cert.pem --cert client.crt --key client_priv.key -

  物联网是新一代信息技术的重要组成部分,也是“信息化”时代的重要发展阶段。其英文名称是:“Internet of things(IoT)”。顾名思义,物联网就是物物相连的互联网。这有两层意思:其一,物联网的核心和基础仍然是互联网,是在互联网基础上的延伸和扩展的网络;其二,其用户端延伸和扩展到了任何物品与物品之间,进行信息交换和通信,也就是物物相息。物联网通过智能感知、识别技术与普适计算等通信感知技术,广泛应用于网络的融合中,也因此被称为继计算机、互联网之后世界信息产业发展的第三次浪潮。   而在物联网的应用上,对于信息传输,MQTT是一种再合适不过的协议工具了。 一、MQTT简介   MQTT(Message Queuing Telemetry Transport,消息队列遥测传输协议),是一种基于发布/订阅(publish/subscribe)模式的轻量级协议,该协议构建于TCP/IP协议之上,MQTT最大优点在于,可以以极少的代码和有限的带宽,为连接远程设备提供实时可靠的消息服务。作为一种低开销、低带宽占用的即时通讯协议,使其在物联网、小型设备、移动应用等方面有较广泛的应用。   MQTT是一个基于客户端-服务器的消息发布/订阅传输协议。MQTT协议是轻量、简单、开放和易于实现的,这些特点使它适用范围非常广泛。在很多情况下,包括受限的环境中,如:机器与机器(M2M
