Why Linux

Linux provides exceptional stability, minimal disk space usage, and robust networking capabilities. It also offers a higher level of security compared to most operating systems. Known for its reliability and resistance to crashes, Linux is an ideal environment for deploying application servers in production.

Linux VM

In case you have windows workstation, you can install linux virtual machine and practice linux.

Steps to install

• Download and install Oracal VM vistual box : Oracle VM
• Install vagrant which is used a config manager for your virtual box : Vagrant
• Install git bash (optional): Git Bash

• Make sure virtualization is on in your bios setting

• create a folder say : my_vm
• create a file Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure("2") do |config|
  config.vm.provision "shell", path: "pg_config.sh"
  config.vm.box = "bento/ubuntu-19.04"
  # config.vm.network "forwarded_port", guest: 80, host: 8080
  config.vm.boot_timeout = 1000
  config.vm.provider "virtualbox" do |v|
  #  v.gui = true
    v.memory = 1024
    v.cpus = 1
  end 	
  config.vm.network "private_network", ip: "10.11.12.14"
  config.vm.hostname = "myvm19"
  config.vm.network :forwarded_port, guest: 22, host: 2224, id: "ssh", auto_correct: true
  # config.vm.box_check_update = false
  # config.vm.synced_folder "../data", "/vagrant_data"
end

• change ubuntu version as per your need ex: config.vm.box = “bento/ubuntu-18.04” or you can change linux distribution as well : config.vm.box = “centos/7”

• create a file : pg_config.sh

  vagrantTip="The shared directory is located at /vagrant\nTo access your shared files: cd /vagrant(B"
  echo -e $vagrantTip > /etc/motd
  

• now open command line and go to my_vm folder and run below commands

vagrant up   # to start vm - first time it will download provided virtual box and complete the setup

vagrant ssh  # to go inside the vm (ssh to vm). you are into linux for your practice

vagrant halt # to turn off vm

vagrant status # to check status of VM - on or off

vagrant destroy # to delete a VM
