下载源码
之前使用的ＥＭＱＸ,现在在树莓派安装另一个ＭＱＴＴServer, mosquitto。 来运行我的ＯrangeIOT。
wget https://mosquitto.org/files/source/mosquitto-1.5.7.tar.gz
安装依赖
su
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 .. -DLIB_SUFFIX=64
make
make install
编译
为了支持websocket，需要修改config.mk, 找到websocket选项 改为yes
WITH_WEBSOCKETS:=yes
make
make install
运行
mosquitto -c 配置文件
测试
mosquitto_sub -t mqtt -u test -P t123456
mosquitto_pub -h localhost -t mqtt -m "hello world" -u test -P t123456
出现错误
mosquitto_sub: error while loading shared libraries: libmosquitto.so.1: cannot open shared object file: No such file or directory
