make
make install
cp mosquitto.conf /etc/mosquitto
修改mosquitto.conf文件
在/etc/mosquitto/mosquitto.conf的Default Listener一節添加如下幾行：
運行mosquitto
mosquitto -c /etc/mosquitto/mosquitto.conf
mosquitto -c /etc/mosquitto/mosquitto.conf -v
或mosquitto -c /etc/mosquitto/mosquitto.conf -d
本機測試mosquitto
在服務器上新建兩個shell，A和B
A 訂閱主題：
mosquitto_sub -t topicA
B 推送消息：
mosquitto_pub -t topicA -h localhost -m "topicA test"
