Introduction
Node.js is particularly known for its event-driven, non-blocking I/O model, which allows it to handle many connections concurrently with minimal overhead.This makes it well-suited for applications that require real-time communication, such as web servers, chat applications, or data-intensive APIs.To install Node.js on AlmaLinux, you can follow these steps. Node.js is available through the official NodeSource repository, which provides the latest stable versions for RHEL-based distributions like AlmaLinux.
Step 1:Update Your System
Start by updating the system packages to ensure your system is up to date.
#sudo dnf update -y
Step 2:Add NodeSource Repository
The easiest way to install Node.js is through the NodeSource repository, which maintains up-to-date versions of Node.js for RHEL-based systems like AlmaLinux.
- Download and add the NodeSource repository for the desired version of Node.js. For example, to install Node.js 18.x (the latest LTS version as of now):
#curl -fsSL https://rpm.nodesource.com/setup_18.x | sudo bash – - If you want to install a different version (e.g., Node.js 16.x or 20.x), replace setup_18.x with setup_16.x or setup_20.x, respectively.
This script will automatically configure the NodeSource repository for you, including the correct GPG keys.
Step 3:Install Node.js
Once the repository is added, install Node.js using the dnf package manager:
#sudo dnf install -y nodejs
This command will install both Node.js and npm (Node Package Manager) on your system.
Step 4: Verify Node.js Installation
After installation, you can verify that Node.js and npm were installed correctly by checking their versions:
#node -v
v18.18.0.
#npm -v
8.19.3
Conclusion:
Successfully installed Node.js on your AlmaLinux server using the NodeSource repository.
- Added NodeSource repository to get the latest Node.js versions.
- Installed Node.js and npm.
- Verified the installation by checking the Node.js and npm versions.
- Optionally, installed development tools for building native Node.js modules.
