二、安装教程

但是cmake 后面不要用64的，树莓派32位所以 cmake .. 即可

1、先安装libwebsockets

sudo apt-get install build-essential python quilt libwrap0-dev libssl-dev devscripts python-setuptools cmake uuid-dev
git clone -b v2.4.1 https://github.com/warmcat/libwebsockets.git
cd libwebsockets
mkdir build
cd build
cmake .. 
sudo make
sudo make install
#这里注意前面的路径是你本地的，后面是指向新生成文件的路径
sudo ln -s /home/pi/libwebsockets/libwebsockets-2.4.1/build/lib/libwebsockets.so.12 /usr/lib/libwebsockets.so.12
sudo ldconfig

2、安装mosquitto

wget https://mosquitto.org/files/source/mosquitto-1.5.7.tar.gz
cd mosquitto-1.5.7
vim config.mk
#修改WITH_WEBSOCKETS的no为yes如下
WITH_WEBSOCKETS:=yes
vim mosquitto.conf
#添加如下内容
user root
port 1883
listener 9001
protocol websockets
#编译开始
sudo make
sudo make install
#软链接一下
sudo ln -s /usr/local/lib/libmosquitto.so.1 /usr/lib/libmosquitto.so.1
sudo ldconfig
#新增mosquitto用户
sudo adduser mosquitto
#开始执行，这里后面路径根据你自己的来
sudo mosquitto -c ~/mqtt/mosquitto-1.5.7/mosquitto.conf

测试如下，复制SSH渠道，复制两次，每个命令窗口运行一条
mosquitto_sub -t hello  
mosquitto_pub -t hello -h localhost -m "hello world!"
