After you add the yum repository to your system, you can install the node.js package. NPM will also be installed with node.js. This command will also install many other dependent packages on the system.

# sudo yum install nodejs

Step 3: check the node.js and npm versions

After installing node.js, you need to verify and check the installed version. More details about the current version can be found on the official node.js website.

In addition, check the version of NPM.

# npm-v 6.7.0

Step 4: create a demo Web server (optional)

This is an optional step. If you want to test the node.js installation. Let's create a Web server with "Welcome Node.js" text. Create a demo_server.js file

# vim demo_server.js

And add the following

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

Now use the command to start the Web server.

# node-- debug demo_server.jsdebugger listening on port 5858Server running at http://127.0.0.1:3001/

The Web server is started on port 3001. Now access http://127.0.0.1:3001/url in your browser.
