sudo ln -s /usr/local/lib/libmosquitto.so.1 /usr/lib/libmosquitto.so.1

添加用户

      sudo groupadd mosquitto
      sudo useradd -g mosquitto mosquitto //可以自定义用户组和用户名

MQTT程序配置

mv /etc/mosquitto/mosquitto.conf.example /etc/mosquitto/mosquitto.conf

启动MQTT

mosquitto -c /etc/mosquitto/mosquitto.conf -d

新建窗口1添加订阅服务

mosquitto_sub -t hello_test

另新建窗口2添加发布服务

mosquitto_pub -t hello_test -h localhost -m "hello world!"

会在新建窗口1中出现  hello world!
