Mosquitto:在仅本地模式下启动，但无法修复

Question

我的运行家庭自动化的Rpi4最近将自己从蚊子升级到版本1.6.12到2.0.8，因此它在仅本地模式下启动。

做了一些挖掘，但仍然不能让它再次工作，主要使用了前面的这个有用的问题Mosquitto: Starting in local only mode但我的设备仍然无法连接。

从我的mosquiito日志中我看到

1614386087: mosquitto version 2.0.8 starting
1614386087: Config loaded from /etc/mosquitto/mosquitto.conf.
1614386087: Opening ipv4 listen socket on port 1883.
1614386087: Opening ipv6 listen socket on port 1883.
1614386087: mosquitto version 2.0.8 running

该服务显示如下

在我的calz.conf文件中，我有

listener 1883
allow_anonymous true

但是我的Domoticz的本地版本(在相同的机器上运行)在它的日志中显示了这一点

Error: Plugin: Connection Exception: 'resolve: Host not found (authoritative)' connecting to '127.0.0.1:1883'
Error: (ShellyMQTT) Failed to connect to: 127.0.0.1:1883, Description: resolve: Host not found (authoritative)

我所有的Tasmota设备现在都显示

14:49:38 MQT: Attempting connection...
14:49:38 MQT: Connect failed to 192.168.1.19:1883, rc -2. Retry in 120 sec

我也能看到端口打开了

有什么想法吗？

Answer 1

我想我最后把它整理好了，奇怪的组合...

更新Mosquito需要侦听器端口和匿名部分，但由于某种原因，我的Raspberry Pi在重启时切换到了来宾网络，并获得了一个新的IP，因此任何东西都不会到达它:(

我意识到当端口正在侦听时无法访问它，然后其他所有东西都是如此，比如kodi，ssh等。我碰巧在控制台上，因为当时它更方便，如果我试图通过SSH连接到它，也会失败。

Answer 2

您的问题不是Mosquitto没有监听，而是您的设备正在尝试解析主机名127.0.0.1:1883

我怀疑您已经在字段中输入了host:port组合，

1. 仅包含主机名/IP地址
2. 你可能不应该进入127.0.0.1因为这总是指向输入它的设备，所以您应该输入代理实际在其上运行的IP地址。
