你好我来自这篇文章为MQTT配置Nginx反向代理
我有一个虚拟机，在这个虚拟机中我有 nginx 代理侦听客户端连接的端口 1885，我想让它在所有 Mosquitto 容器之间重新分发消息（在这个例子中我删除了其他两个容器我有）这个来创建一个蚊子体积
version: '3'
services:
nginx:
image: nginx:latest
ports:
- "1885:1885"
- "443:443"
volumes:
- ./nginx.conf:/var/lib/docker/volumes/nginx-conf/_data/nginx.conf
networks:
- backend
mosquitto1:
image: eclipse-mosquitto
ports:
- "1886:1886"
environment:
- listener=1886:1886
- allow_anonymous=true
networks:
- backend
volumes:
- ./mosquitto.conf:/etc/mosquitto/mosquitto.conf
networks:
backend:
driver: bridge
然后我有 nginx.conf
events {
}
http {
upstream mosquitto_backend {
zone tcp_mem 64k;
proxy_protocol on;
}
server {
listen 1885;
server_name localhost;
log_format mqtt '$remote_addr [$time_local] $protocol $status $bytes_sent $bytes_received $session_time "$request" "$http_referer" "$http_user_agent" "$upstream_addr"';
access_log /var/log/nginx/mqtt_access.log mqtt;
error_log /var/log/nginx/mqtt_error.log; # Health check notifications
location / {
proxy_pass http://mosquitto_backend;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
}
}
我遇到的问题是尽管能够订阅端口 1885，但我无法从其他终端写入消息或使用 mqtt explorer 连接
运行 docker-compose up 将在它尝试使用端口 1883 并与某些东西发生冲突时返回此消息
docker-compose up --remove-orphans

我用lsof -i:1883和netstat -tuln看这个端口有没有被占用
我知道我正在使用一个图像 eclipse-mosquitto 并且该图像应具有端口 1883，尽管稍后更改它访问它并且如果是这样的话没问题，但我不知道还有什么正在访问它制作冲突。
你能帮帮我吗？
你正在尝试的一些问题
您已将
mosquitto.conf/mosquitto/config/mosquitto.conf/etc/mosquitto/mosquitto.confenvironmentmosquitto.conf您不能将 HTTP 代理与本机 MQTT 一起使用，它们只是完全不同的协议。您可以在流代理模式下配置 Nginx，这将起作用。您可以配置 mosquitto 以支持 WebSockets 上的 MQTT（同样您需要提供一个配置文件来启用此功能），它将与 HTTP 代理一起使用，但确实依赖于您的所有客户端也支持 WebSockets 上的 MQTT 并专门配置为使用它.
除非您配置多个 MQTT 代理之间的桥接，否则此设置将不起作用。由于没有桥接，发布到一个代理的消息将不会最终传递给连接到其他 2 个代理的任何客户端。 （mosquitto 容器之间的共享卷不会共享任何消息）
