Introductions:
Node.js is a powerful, open-source JavaScript runtime environment that allows developers to build fast, scalable, and server-side applications. It’s widely used for developing web servers, APIs, and full-stack JavaScript applications.
In this guide, we’ll walk you through step-by-step instructions to install Node.js on your Linux server (Ubuntu, Debian, AlmaLinux, CentOS, or Rocky Linux) using different methods.
Prerequisites
Before starting, make sure:
- You have SSH access to your Linux server.
- You are logged in as a root user or a user with sudo privileges.
- The system is up-to-date.
Update your server package list:
sudo apt update && sudo apt upgrade -y # For Ubuntu/Debian
sudo dnf update -y # For AlmaLinux/CentOS/RockyStep 1: Check if Node.js Is Already Installed
First, verify if Node.js is already installed on your server:
node -vIf you see a version number (e.g., v20.11.0), Node.js is already installed.
If not, continue with the installation steps below.
Step 2: Install Node.js Using the Package Manager
Install from the Default Repository
Most Linux distributions include Node.js in their repositories, but the version may be outdated.
On Ubuntu/Debian:
sudo apt install nodejs -y
sudo apt install npm -y
On CentOS/RHEL/AlmaLinux:
sudo dnf module install nodejs:20 -yAfter installation, verify:
node -v
npm -v
