NGINX _ nginx 上的 rtmp nodejs 服务器配置：[emerg] bind() to 0.0.0.0:1935 failed (98: Address already in use)

Question

I have media server running on port 1935.

and I have a subdomain: "streaming.foo.com"

I need to configure Nginx to access rtmp://streaming.foo.com

I tried the RTMP Nginx plugin with this blog:

https://www.nginx.com/blog/video-streaming-for-remote-learning-with-nginx/

and configured the /etc/nginx/nginx.conf file.

rtmp {
    server {
        listen 1935;
        application live {
            live on;
            dash on;
            dash_path /tmp/dash; // what is this config??
            dash_fragment 15s;
        }
    }
}

but I get this error from nginx:

nginx[176987]: nginx: [emerg] bind() to 0.0.0.0:1935 failed (98: Address already in use)

Answer 1

It is RTMP , not HTTP . Nginx is a web server, which can proxy and balance HTTP only. It is not a general proxy server.

Use a general Proxy or Load balancer, like HA Proxy .

Answer 2

You can't have two services listening on the same port.

The common solution is to configure the real service (your media service) on another port (let's say 19350) than configure a reverse proxy on nginix to forward requests from the exposed port (1935 in this case) to the back-end service (19350 in our example).

Sorry but I don't know nginix (I use this config with apache) so I can't help you on how to configure a reverse proxy on it.
