如何在不通过NginX的情况下从外部访问流星应用？

Question

I am hosting a meteor app on an Ubunu Linux machine. The app is listening on port 3000 . If I use a webserver, like NginX and forwards the HTTP requests from port 80 to 3000 I can browse to the server from the outside and see reach the app. However, when I try to access the app directly at port 3000 , ie browse http://myhost:3000 it just tries to connect and nothing happens.

I have made sure that all firewalls are down and that the app is listening on all interfaces, ie 0.0.0.0:3000 , so that is not the issue.

To verify that port was actually reachable, I created a simple node js webserver:

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write('Hello World!');
  res.end();
}).listen(3000);

Now browsing to the the sever, I can see "Hello World!" . So obviously this works so why I can not reach meteor has nothing to do with firewalls or unopened ports.

Thus it seems that there is something strange when trying to access a meteor app directly at port 3000. But why? I use the following environment variables:

export MONGO_URL=mongodb://localhost:27017/meteor
export HOST=myhost
export PORT=3000
export ROOT_URL=http://myhost

So what am I missing? Ports are open and I can see that the node process instance is listening on port 3000 when I run netstat -tulpan

Answer 1

I was using the force-ssl meteor package which makes a redirect back to the ROOT_URL without port number. So solution is to remove the package to make it work with a custom port.

I was discussing the solution on the meteor forum where I got the solution: https://forums.meteor.com/t/can-not-access-meteor-app-without-passing-through-nginx-server/40739/11
