在AWS EC2上设置SocketIO服务器

Question

I've got a problem to run the server with socketIO module on AWS EC2 server. My current code:

const port     = process.env.PORT || 8080;
var server = require('http').Server();
var io = require('socket.io')(server);
const socketioHandler = require(backPath + 'functions/socketioHandler');
socketioHandler.ioConnections(io);

server.listen(port, 'ec2-IP_XXX.compute-1.amazonaws.com');

And the URI that I'm using to connect client to the server:

ec2-IP_XXX.compute-1.amazonaws.com:8080

It seams that for some reason the client cannot find the server.

Answer 1

This is the issue regarding the Security Group.

Security Groups has an Inbound rule, which is actually related to Port block or which all port should be open for the outside world.

So you have to open port 8080 for outside world.

So just add port 8080 (through edit option) in your inbound rules
