node.js - Why this port number is not acceptable for my localhost server? -

-

i have hapi.js code below: ` 'use strict';

const hapi = require("hapi");  const server = new hapi.server();  server.connection({     host: 'localhost',     port: 2922, });  server.route({     method: 'get',     path: '/hello',     handler: function (req, res) {                     res('hello world hapi.js');     } });  server.start((err) => { });

` problem when run server port number 22291 executes , exit without error, reason for? using linux centos 7

you need check error in start callback:

server.start((err) => {    if (err) throw err; });

that give details need debug. make sure check errors in callbacks or you'll repeatedly run problem in node.
