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

Install Node.js is very easy in ubuntu server.Node.js is a JavaScript runtime for server-side programming. It allows developers to create scalable backend functionality using JavaScript, a language many are already familiar with from browser-based web development.<\/p>\n

In this guide, we will show you three different ways of getting Node.js installed on an Ubuntu 20.04 server.Node.js is a powerful and versatile runtime environment that allows developers to execute JavaScript code on the server side.<\/p>\n

Installing Node.js on the latest version of Ubuntu is straightforward. You can use several methods, but here\u2019s a common and reliable way using the NodeSource repository. Follow these steps,<\/p>\n

Step 1: Update Your Package Index<\/h3>\n

First, open a terminal and update your package index to ensure you have the latest information on available packages.<\/p>\n

sudo apt update<\/pre>\n
Step 2: Install Required Packages<\/h3>\n
You’ll need curl<\/code> to fetch the installation script. If you don\u2019t have it installed, you can do so with below command<\/p>\n
sudo apt install curl<\/pre>\n
Step 3: Download and Install Node.js<\/h3>\n
NodeSource maintains a repository for Node.js. You can choose the version you want to install (e.g., Node.js 16 or 18). Here\u2019s how to install Node.js 18<\/p>\n
curl -fsSL https:\/\/deb.nodesource.com\/setup_18.x | sudo -E bash -<\/pre>\n
Then, install Node.js:<\/p>\n
sudo apt install -y nodejs<\/pre>\n
Step 4: Verify the Installation<\/h3>\n
To check if Node.js and npm (Node Package Manager) are installed correctly, run<\/p>\n
node -v\r\nnpm -v<\/pre>\n
Step 5: Install Build Tools (Optional)<\/h3>\n
If you plan to compile and install native add-ons from npm, it\u2019s a good idea to install build tools<\/p>\n
sudo apt install -y build-essential<\/pre>\n
To host your Node.js application on Ubuntu, you\u2019ll need to set up a few things beyond just installing Node.js. Here\u2019s a step-by-step guide to help you get started<\/p>\n
Step 1: Prepare Your Application<\/h3>\n
Make sure your Node.js application is ready. If you haven’t created one yet, you can create a simple app as follows<\/p>\n
Create a project directory<\/p>\n
mkdir myapp\r\ncd myapp<\/pre>\n
Initialize a new Node.js project<\/p>\n
npm init -y<\/pre>\n
create a simple server in index.js<\/code><\/p>\n
const http = require('http');\r\n\r\nconst hostname = '0.0.0.0';\r\nconst port = 3000;\r\n\r\nconst server = http.createServer((req, res) => {\r\nres.statusCode = 200;\r\nres.setHeader('Content-Type', 'text\/plain');\r\nres.end('Hello World\\n');\r\n});\r\n\r\nserver.listen(port, hostname, () => {\r\nconsole.log(`Server running at http:\/\/${hostname}:${port}\/`);\r\n});<\/pre>\n
Install PM2 (Process Manager)<\/h3>\n
PM2 is a popular process manager for Node.js applications that helps keep your app running. Install it globally<\/p>\n
sudo npm install -g pm2<\/pre>\n
Step 3: Start Your Application with PM2<\/h3>\n
Run your application using PM2:<\/p>\n
pm2 start index.js --name myapp<\/pre>\n
Step 4: Set Up PM2 to Run on Startup<\/h3>\n
To ensure PM2 starts your app on server reboot, run<\/p>\n
pm2 startup\r\npm2 save<\/pre>\n
Step 5: Configure a Reverse Proxy with Nginx<\/h3>\n
Using Nginx as a reverse proxy will help manage incoming traffic to your Node.js application.<\/p>\n
Install Nginx:<\/strong><\/p>\n
sudo apt install nginx<\/pre>\n
Configure Nginx:<\/strong> Create a new configuration file for your application:<\/p>\n
sudo nano \/etc\/nginx\/sites-available\/myapp<\/pre>\n
Add the following configuration, replacing your_domain_or_IP<\/code> with your domain name<\/a> or server IP address:<\/p>\n
server {\r\nlisten 80;\r\nserver_name your_domain_or_IP;\r\n\r\nlocation \/ {\r\nproxy_pass http:\/\/localhost:3000; # The port your app is running on\r\nproxy_http_version 1.1;\r\nproxy_set_header Upgrade $http_upgrade;\r\nproxy_set_header Connection 'upgrade';\r\nproxy_set_header Host $host;\r\nproxy_cache_bypass $http_upgrade;\r\n}\r\n}<\/pre>\n
Enable the configuration:<\/p>\n
sudo ln -s \/etc\/nginx\/sites-available\/myapp \/etc\/nginx\/sites-enabled\/<\/pre>\n
Test Nginx configuration:<\/p>\n
sudo nginx -t<\/pre>\n
Restart Nginx:<\/p>\n
sudo systemctl restart nginx<\/pre>\n
Step 6: Open Your Firewall (If Applicable)<\/h3>\n
If you have a firewall running (like UFW), allow HTTP traffic<\/p>\n
sudo ufw allow 'Nginx Full'<\/pre>\n
Step 7: Access Your Application<\/h3>\n
Now, you should be able to access your application by navigating to http:\/\/your_domain_or_IP<\/code> in your web browser.<\/p>\n
Conclusion<\/h3>\n
Your Node.js application is now hosted on your Ubuntu server! If you have any further questions or need more details on specific steps, feel free to ask.<\/p>\n
