Introduction:<\/strong><\/p>\n\n\n\n

Node.js is a JavaScript runtime environment that allows developers to write server-side applications using the same language as client-side web development. It uses an event-driven, non-blocking I\/O model that makes it efficient and scalable, even for handling large amounts of data in real-time. Its rich library of modules and tools makes it a popular choice for building web APIs and microservices.<\/p>\n\n\n\n

Prerequisites<\/strong>:<\/p>\n\n\n\n

SSH login details<\/p>\n\n\n\n

Procedure<\/strong>:<\/p>\n\n\n\n

Step 1: <\/strong>Login to the server via ssh<\/p>\n\n\n\n

$ ssh username@IP<\/mark><\/p>\n\n\n\n

Step 2:<\/strong> Install the Node.js stable version.<\/p>\n\n\n\n

$ sudo apt install nodejs -y<\/mark><\/p>\n\n\n\n

The above command is used for ubuntu os, For centos you can use yum<\/strong> instead of apt<\/strong>.<\/p>\n\n\n\n

Step 3:<\/strong> Verify the installed Node.js version.<\/p>\n\n\n\n

$ sudo nodejs -v<\/mark><\/p>\n\n\n\n

Step 4: <\/strong>Create the sample .js file using the command as mentioned below,<\/p>\n\n\n\n

$ sudo vim test.js<\/mark><\/p>\n\n\n\n

Step 5: <\/strong>Copy paste the below content in that test.js file<\/p>\n\n\n\n

const http = require(‘http’);
const hostname = ‘127.0.0.1’;
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader(‘Content-Type’, ‘text\/plain’);
  res.end(‘Hello World!<\/code>‘);
});

server.listen(port, hostname, () => {
  console.log(`Server running at http:\/\/${hostname}:${port}\/`);
});<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Step 6:<\/strong> Start the node using the following command, <\/p>\n\n\n\n

$ sudo node test.js<\/mark><\/p>\n\n\n\n

Now the node gets started.<\/p>\n\n\n\n

Step 7:<\/strong>  If the port is blocked in the firewall run the below command to allow the port,<\/p>\n\n\n\n

$ sudo iptables -I INPUT 1 -p tcp –dport 3000 -j ACCEPT<\/mark><\/p>\n\n\n\n

Step 8: <\/strong>Then try to start a node, using the node command below.<\/p>\n\n\n\n

$ sudo node test.js<\/mark><\/p>\n\n\n\n

Open a browser and enter url http:\/\/127.0.0.1:3000\/<\/a>. The browser will display Hello World!<\/code><\/strong> message on the screen.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Conclusion:<\/strong><\/p>\n\n\n\n

You have installed Node.js and successfully started the node on server.<\/p>\n","protected":false},"excerpt":{"rendered":"
