Mosquitto－Ubuntu 14.04快速安装问题解决

Mosquitto是一个轻量级的MQTT Broker，支持很多种系统。

下载与安装：http://mosquitto.org/download/

注意：由于客户端paho工程进展较快，目前需要使用最新的3.1.1版本的mqosuitto服务器才能连接，因此用Ubuntu内置库的mosquitto将无法正常访问。我就是因为这个莫名奇妙的原因，死活调试不通org.eclipse.paho.mqtt.embedded-c-1.0.0源码中示例，折腾了好几天。

安装最新的1.4以上版本的Mosquitto(适用于所有基于Debian的Linux ,如Ubuntu系列)，步骤如下：

#!/bin/sh#To use the new repository you should first import the repository package signing key:
wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
sudo apt-key add mosquitto-repo.gpg.key#Then make the repository available to apt:
cd /etc/apt/sources.list.d/#Then one of the following, depending on which version of debian you are using:
sudo wget http://repo.mosquitto.org/debian/mosquitto-wheezy.list
#sudo wget http://repo.mosquitto.org/debian/mosquitto-jessie.list#Then update apt information:
sudo apt-get update#And discover what mosquitto packages are available:
sudo apt-cache search mosquitto#Or just install:
sudo apt-get install mosquittoecho =========================================
echo MQTT Broker-Mosquitto Server Installed.
