Question

我坚持在Raspberry Pi上安装Mosquitto - 我安装了它：

aptitude install mosquitto mosquitto-clients python-mosquitto libmodule-pluggable-perl

这是我的配置：

pid_file /var/run/mosquitto.pid

persistence true
persistence_location /var/lib/mosquitto/
log_timestamp true 
password_file /etc/mosquitto/passwd


listener 1883 127.0.0.1 
listener 8883


log_dest file /var/log/mosquitto/mosquitto.log

include_dir /etc/mosquitto/conf.d

日志显示该服务已启动＆amp;运行：

netstat -an | grep 1883什么也没显示，端口没有收听。任何提示？出了什么问题？

Answer 1

如果netstat -an| grep 1883没有显示任何内容，则mosquitto可能无法运行，因为1883被配置为mosquitto代理配置文件的监听器。请检查运行ps aux|grep mosquitto的mosquitto进程是否正确，以便确认mosquitto是否正在运行。尝试sudo service mosquitto status也检查蚊子的服务状态。

最好运行killall -9 mosquitto以杀死蚊子进程。

如果没有运行，你可以执行mosquitto -c /etc/mosquitto/mosuitto.conf来运行mosquitto。这里可以使用配置文件的路径。您可以通过mosquitto -c /etc/mosquitto/mosuitto.conf -d

将mosquitto作为守护进程运行
