//編譯執行測試
//當須要添加用戶時，有兩種方法，一修改配置文件，給pc主機添加用戶，推薦第一種

//單向認證與雙向認證

一、修改config.mk
prefix=/home/retry/mqtt_pc //指定本身的編譯路徑

二、編譯
make WITH_SRV=no 

三、安裝
make install


四、拷貝一份mosquitto.conf到etc目錄下

五、測試
mosquitto -c /etc/mosquitto/mosquitto.conf   //啓動代理
mosquitto_pub  -p 1883 -t "mqtt/server/topic" -m " hello,world"
mosquitto_sub  -p 1883 -t "mqtt/server/topic" 


2、ssl認證
一、修改mosquitto.conf文件

mosquitto -c /etc/mosquitto/mosquitto.conf   //啓動代理
mosquitto_pub  -p 1883 -t "mqtt/server/topic" -m " hello,world" --cafile /etc/mosquitto/ca.crt --insecure
mosquitto_sub  -p 1883 -t "mqtt/server/topic" --cafile /etc/mosquitto/ca.crt --insecure

測試發現：--insecure不加會致使鏈接失敗。
