MQTTbridge_to_target授权问题

Question

我正在尝试在一台 Linux 设备上运行两个单独的代理。

我使用以下小脚本设置了两个代理（为了便于阅读，省略了第二个脚本，因为它是相同的，除了结尾的 IoT 更改为 HA 并且端口为 1884）：

temp_file=/tmp/mosquittoIoT.conf
cat <<EOF > $temp_file
listener 1883
allow_anonymous false
password_file /etc/mosquitto/conf.d/brokerIoT/credentialsIoT

connection bridge_to_target
address 192.168.0.2:1884  # Assuming the target broker is running on port 1884
topic cmnd/# both 0

log_dest file /var/log/mosquitto/mosquitto.log
log_type all
EOF
sudo mv $temp_file /etc/mosquitto/conf.d/brokerIoT/mosquittoIoT.conf

temp_file=/tmp/mosquittoIoT.service
cat <<EOF > $temp_file
[Unit]
Description=Mosquitto MQTT Broker IoT

[Service]
ExecStart=/usr/sbin/mosquitto -c /etc/mosquitto/conf.d/brokerIoT/mosquittoIoT.conf

[Install]
WantedBy=multi-user.target
EOF
sudo mv $temp_file /etc/systemd/system/mosquittoIoT.service

我正在尝试同步两个经纪人之间的

我不明白为什么会出现授权问题。两个经纪商使用相同的用户名和密码。我可以与 MQTT Explorer 连接，并且我的设备正在成功向两个代理发送数据。这似乎只是桥上的问题。

有人看到我做错了什么吗？

谢谢大家 亚历克斯

您需要在配置文件中指定

local_user

、

local_password

、

remote_user

和

remote_password

，以便代理知道在桥的两端使用哪些凭据。
