Answer:
Before start, please make sure you already install nodejs and npm. Let's go to /root/bin for example. Name a file server.js
In this section, nodejs will deploy custom port 3000 and listening all network interfaces.
const http = require('http');
const hostname = '0.0.0.0'; // Listen on all network interfaces
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello, World from Exabytes!\n');
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});And then run it.
# node server.js Server running at http://0.0.0.0:3000/
Check at your browser and open IP server with port 3000
You can change to random ports as your project needs.
