The above command will download Nodejs rpm package in our system.
For my case, the package of nodejs is nodejs-13.5.0-1nodesource.x86_64.rpm. You may also choose the newer packages of Node.js. let’s install the package with the following command:-

$ sudo rpm -ivh --nodeps nodejs-13.5.0-1nodesource.x86_64.rpm

Step 4 – Create demo on Web Server.

If you want to check and verify your node.js installed. Let’s create a web server with “Hellow World !!! Welcome to the Node.js world !!!” text. Creating a file with name test_server.js like below:-

# vim test_server.js

After creating a file adding the some following content

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hellow World !!! Welcome to the Node.js world !!!');
}).listen(3001, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3001/');

 

Now start the webserver using the following command.

# node --inspect demo_server.js

Debugger listening on ws://127.0.0.1:9229/9e0c7b4a-2ffe-48df-a4b0-b4635dcd9359
For help, see: https://nodejs.org/en/docs/inspector
Server running at http://127.0.0.1:3001/

 

Now Web server has been started on port number 3001.
Please check this http://127.0.0.1:3001/ url in browser.
