Vagrant: Creating Oracle Virtual Machines using Vagrant

Share At:

Introduction:

Vagrant is a tool for building and managing virtual machine environments in a single workflow. With an easy-to-use workflow and focus on automation, Vagrant lowers development environment setup time, increases production parity, and makes the “works on my machine” excuse a relic of the past.

Tools Needed to use vagrant:

In order to use vagrant, you should have following tools installed on your machine:

  1. Git
  2. Vagrant
  3. Oracle Virtual Box

Once you have downloaded and installed all the above tools, you can use “Gitbash” to create virtual machines so easily using vagrant.

1. Open Gitbash:

Look for your programs and open Gitbash.

You will see a unix shell like prompt.

2. Create a directory where you want your virtual machines to be created:

3. Change to the directory by using cd command:

4. Initialize Vagrant by using “vagrant init”

5. Now open the Vagrantfile using your favourite editor like Vi, Vim, etc and make below changes (as per your requirement):

config.vm.box = “bento/centos-7.5”

config.vm.network “private_network”, ip: “192.168.33.14”

vb.memory = “2048”

vb.cpus = “2”

6. Now create the machine with Configuration mentioned in the “Vagrantfile” using “Vagrant up” command:

Abhinav-PC@DESKTOP-81JH4D6 MINGW64 /e/gitlab/lab1/vm1

$ vagrant up

Bringing machine ‘default’ up with ‘virtualbox’ provider…

==> default: Box ‘bento/centos-7.5’ could not be found. Attempting to find and install…

……

default: shared folder errors, please make sure the guest additions within the

default: virtual machine match the version of VirtualBox you have installed on

default: your host and reload your VM.

default:

default: Guest Additions Version: 5.2.18

default: VirtualBox Version: 6.1

==> default: Configuring and enabling network interfaces…

==> default: Mounting shared folders…

default: /vagrant => E:/gitlab/lab1/vm1

Congratulations !!! Your Virtual Machine is Ready to use.

7. Login to your virtual machine by using “vagrant ssh” command:

8. Set your machine’s hostname by using bellow command:

[root@localhost ~]# hostnamectl set-hostname git.unixcloudfusion.in

Your Machine is ready to use !!!

Happy Learning !!!
