[SOLVED] How to run NodeJs SocketIO on server (Centos 7)

Issue

I create app with nodejs socket io. It works clearly at localhost (port: 3000). But when i deploy it to my server in there i can run my app on 3000 port but client side throw timeout. How can i solve it?

var fs = require('fs');

var https = require('https');
var options = {
  key: fs.readFileSync('ssl.my-key.key'),
  cert: fs.readFileSync('ssl.my-cert.crt')
};
var server = https.createServer(options);
var io  = require('socket.io').listen(server);
var port = 3000;

const database = require('./Database');

io.on('connection', (socket) => {

  socket.on('message', async (msg) => {
    // I do some action here.
  });

  socket.on('disconnect', (msg) => {
    // some action in here too
  });

});

server.listen(port, () => {
  console.log('listening on *:' + port);
});

Solution

It seems like your issue is with port forwarding. In order for your server to be publicly accessed, it needs to have all ports forwarded appropriately. Locally and on the router.

Check this link to learn more about how to port forward on linux: https://linuxacademy.com/guide/11630-internal-port-forwarding-on-linux-using-the-firewall/

And this to learn more about router port forwarding, but this will really depend on your router.

However, I don't recommend you to take care of hosting on your own machine(s). I suggest you use Heroku, you can op in for their free servers, you don't need to pay.
