我尝试在嵌入式Linux设备上运行mosquitto，并配置（如下所示）作为root用户和cmd：mosquitto -c /etc/mosquitto/mosquitto.conf
### /etc/mosquitto/mosquitto.conf ###
log_dest stdout
#mosquitto user
user mosquitto
#bridge Config
connection 1234567890
address 192.168.0.101:1883
start_type automatic
topic # both 0
topic # both 1
#cleansession false
bridge_protocol_version mqttv311
#need to be false otherwise error on hivemq-side
notifications false
### end of conf file ###
mosquitto无法创建桥梁，我抓住了这个日志：
1472052730: mosquitto version 1.4.8 (build date 2016-07-05 08:47:49+0200) starting

然而，当我将conf文件中的用户从mosquitto更改为root（但我知道它不正确）时，一切正常。 你能帮我解决这个问题吗？
