Mosquitto 未从 conf.d 加载配置文件

Question

我在树莓派3上安装了mosquito v2.0.11。我写了配置文件，允许匿名连接，但是mosquitto好像不加载这个配置。

/etc/mosquitto/conf.d/custom.conf:

listener 1883
allow_anonymous true

当我在 bash 中运行 "mosquitto" 时，输出如下所示：

1636892708: mosquitto version 2.0.11 starting
1636892708: Using default config.
1636892708: Starting in local only mode. Connections will only be possible from clients running on this machine.
1636892708: Create a configuration file which defines a listener to allow remote access.
1636892708: For more details see https://mosquitto.org/documentation/authentication-methods/
1636892708: Opening ipv4 listen socket on port 1883.

1636892708: Opening ipv6 listen socket on port 1883.
1636892708: Error: Address already in use

并且“systemctl status mosquitto.service”表示已加载 congfig 文件。仍然无法使用匿名连接。

当我指定配置文件时，通过“mosquitto -c /etc/mosquitto/conf.d/custom.conf”，配置文件被正确加载。我真的不知道如何让它发挥作用。

Answer 1

Mosquitto 不会自动加载配置文件，如果您想使用除默认值。当运行作为服务时，服务定义包括指向默认配置文件的 -c。

默认配置文件通常存储在/etc/mosquitto/mosquitto.conf中。该文件包括以下行：

include_dir /etc/mosquitto/conf.d

这告诉 mosquitto 包含 /etc/mosquitto/conf.d 目录

中所有以 .conf 结尾的文件

当您尝试运行 mosquitto 而不向其传递配置文件时，它失败了，因为该服务已经运行ning。如果您停止它 (sudo service mosquitto stop) 然后运行 mosquitto -c /etc/mosquitto/mosquitto.conf 它会更进一步但也会失败，因为您的用户将无法访问默认持久性文件或日志文件。

最简单的解决方案就是用

重新启动服务

sudo service mosquitto restart

它会获取您在 /etc/mosquitto/conf.d/custom.conf

中所做的更改

然后您应该检查日志文件 (/var/log/mosquitto/mosquitto.log) 以了解您的匿名客户端为何仍无法连接的指示。
