Introduction

Welcome to this tutorial, where we’ll guide you through the process of install Nodejs on Rocky Linux or RHEL Linux using Vagrant. Node.js is a powerful runtime that allows you to run JavaScript on the server side, making it a crucial component for various web applications and development projects. With the help of Vagrant, we’ll simplify the installation process and ensure a smooth setup on your Rocky Linux or RHEL Linux environment.

What does Nodejs mean?

Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser. quote from Wikipedia.

My Setup for Installing Node.js with Vagrant

• Host OS: Window 11
• Vagrant version: 2.2.18
• Vagrant provider: VirtualBox
• Boxes Vagrant: rockylinux/8
• Terminal/PowerShell

The structure of the Vagrant directory and files will appear as follows:

C:\MYDATA\VAGRANT_VMS\PROJECTS\VAGRANT\ROCKY-NODEJS
│   Vagrantfile
│
├───sample-app
└───shell
        init-nodejs.sh

I created an init-nodejs.sh script to Install Node.JS from Nodesource Repositories or Install Node.JS from Rocky Linux AppStream Repositories.

The script content is as follows:

#!/bin/bash

# Update your system
sudo yum update -y
#Tools
sudo dnf install -y git unzip net-tools

# Install Node.JS from Rocky Linux AppStream Repositories
#sudo dnf module list nodejs -y 
#sudo dnf module install nodejs:14
#sudo dnf install nodejs
#node -v
#npm -v

# Install Node.JS from Nodesource Repositories
# curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -   # For ubuntu Server
curl -sL https://rpm.nodesource.com/setup_16.x | sudo bash -
sudo dnf install nodejs -y 
# Check version
node -v
npm -v


echo "##########################"
echo "Run npm install and then run app..."
echo "##########################"
#mkdir sample-app
#cd sample-app
#sudo npm install
#sudo forever start server.js


echo "##########################"
echo "Success! Navigate to localhost..."
echo "##########################"

Set Up a Virtual Machine

Navigate to my working directory

cd Rocky-Nodejs
vagrant init rockylinux/8

Configure the Virtual Machine

Edit the Vagrantfile and paste the content below

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|

  config.vm.box = "rockylinux/8"
  config.ssh.insert_key = false  

  config.vbguest.auto_update = false
  # Uncomment this if you want to link to a shared folder (e.g. if you are running source control and want to link it to Vagrant)
  config.vm.synced_folder "./sample-app", "/home/vagrant/sample-app", create: true, group: "vagrant", owner: "vagrant"
  
  config.vm.define "nodeserver" do |nodeserver|
    nodeserver.vm.hostname = "devopsroles.com"
    nodeserver.vm.network "private_network", ip: "192.168.4.4"
    nodeserver.vm.network "forwarded_port", guest: 3000, host: 3000
    nodeserver.vm.provision "shell", 
      path: "C:\\MyData\\Vagrant_VMS\\Projects\\Vagrant\\Rocky-Nodejs\\shell\\init-nodejs.sh"

  end

end

Use Vagrant install Nodejs on Rocky Linux
