1. install:

https://mosquitto.org/download/

2. conf:

打开/etc/mosquitto/mosquitto.conf，发现需要将配置文件放置于/etc/mosquitto/conf.d/目录下，示例文件可以从/usr/share/doc/mosquitto/examples/目录下提取，发现其是一个压缩包，将其解压缩，然后复制到/etc/mosquitto/conf.d/目录下。

xx@ubuntu:/etc/mosquitto$ cd /usr/share/doc/mosquitto/examples/
xx@ubuntu:/usr/share/doc/mosquitto/examples$ ls -lh

cd /usr/share/doc/mosquitto/examples/
sudo gzip -d mosquitto.conf.gz
sudo cp mosquitto.conf /etc/mosquitto/conf.d/

手动启动mosquitto，方便查看日志排查出现的问题。

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

配置文件如上配置，然后启动mosquito。

3. stat:

service mosquitto status    // 查看服务状态
service mosquitto start     // 启动
service mosquitto stop      // 停止
service mosquitto restart   // 重启

4. test:

mosquitto_sub -h "192.168.10.111" -p 1883 -t "mqtt/test" -v

mosquitto_pub -h "192.168.10.111" -p 1883 -t "mqtt/test" -m "hello"
