How to create CentOS VM using Vagrant

Create CentOS VM using Vagrant


1. Download and install the latest Oracle VM VirtualBox. 

https://www.oracle.com/technetwork/server-storage/virtualbox/downloads/index.html

Like (For Mac OS X)
https://download.oracle.com/virtualbox/6.0.6/VirtualBox-6.0.6-130049-OSX.dmg

2. Download and install the latest Vagrant.

https://www.vagrantup.com/downloads.html

Like (For Mac OS X)
https://releases.hashicorp.com/vagrant/2.2.4/vagrant_2.2.4_x86_64.dmg

3. Download "centos/7" Vagrant Box using below command.

abhinavs-Air:~ agupta$ vagrant box add centos/7
==> box: Loading metadata for box 'centos/7'
    box: URL: https://vagrantcloud.com/centos/7
This box can work with multiple providers! The providers that it
can work with are listed below. Please review the list and choose
the provider you will be working with.


1) hyperv
2) libvirt
3) virtualbox
4) vmware_desktop


Enter your choice: 3
==> box: Adding box 'centos/7' (v1902.01) for provider: virtualbox
    box: Downloading: https://vagrantcloud.com/centos/boxes/7/versions/1902.01/providers/virtualbox.box
    box: Download redirected to host: cloud.centos.org
==> box: Successfully added box 'centos/7' (v1902.01) for 'virtualbox'!
abhinavs-Air:~ agupta$ 

4. Create a directory "centos7-test-vm" and create Vagrant config file.

abhinavs-Air:~ agupta$ mkdir -p vagrant_box/centos7-test-vm

abhinavs-Air:~ agupta$ cd vagrant_box/centos7-test-vm

abhinavs-Air:centos7-test-vm agupta$ vagrant init
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

abhinavs-Air:centos7-test-vm agupta$ ls -lrth

5. Check default vagrant file content.

abhinavs-Air:centos7-test-vm agupta$ cat Vagrantfile

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.
Vagrant.configure("2") do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at
  # https://docs.vagrantup.com.


  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://vagrantcloud.com/search.
  config.vm.box = "base"


  # Disable automatic box update checking. If you disable this, then
  # boxes will only be checked for updates when the user runs
  # `vagrant box outdated`. This is not recommended.
  # config.vm.box_check_update = false


  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,
  # accessing "localhost:8080" will access port 80 on the guest machine.
  # NOTE: This will enable public access to the opened port
  # config.vm.network "forwarded_port", guest: 80, host: 8080


  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine and only allow access
  # via 127.0.0.1 to disable public access
  # config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"


  # Create a private network, which allows host-only access to the machine
  # using a specific IP.
  # config.vm.network "private_network", ip: "192.168.33.10"


  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  # config.vm.network "public_network"


  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is

  # argument is a set of non-required options.
  # config.vm.synced_folder "../data", "/vagrant_data"


  # Provider-specific configuration so you can fine-tune various
  # backing providers for Vagrant. These expose provider-specific options.
  # Example for VirtualBox:
  #
  # config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
  #   vb.memory = "1024"
  # end
  #
  # View the documentation for the provider you are using for more
  # information on available options.


  # Enable provisioning with a shell script. Additional provisioners such as
  # Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the
  # documentation for more information about their specific syntax and use.
  # config.vm.provision "shell", inline: <<-SHELL
  #   apt-get update
  #   apt-get install -y apache2
  # SHELL
end
abhinavs-Air:centos7-test-vm agupta$ 

6. Edit below highlighted content inside the Vagrantfile.

- Change config.vm.box = "base" to "centos/7"

- Add config.vm.hostname = "centos7-test-vm"

- Uncomment config.vm.network "private_network", ip: "192.168.33.10" [Note : If default IP is already been used by any other VM then change it.] 

- Uncomment below section to define custom Physical RAM memory 

    config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true ---> This section can been uncommentted if you need GUI interface of VM.
  #
  #   # Customize the amount of memory on the VM:
      vb.memory = "1024"
    end 

7. Below is the content of Vagrantfile after editing above content

end
abhinavs-Air:centos7-test-vm agupta$ 

8. Now Start/UP CentOS VM. Verify current directory is "centos7-test-vm" directory. 

abhinavs-Air:centos7-test-vm agupta$ pwd
/Users/agupta/vagrant_box/centos7-test-vm

abhinavs-Air:centos7-test-vm agupta$ vagrant up

9. Verify VM created successfully and it is up/running. 

abhinavs-Air:centos7-test-vm agupta$ pwd
/Users/agupta/vagrant_box/centos7-test-vm

abhinavs-Air:centos7-test-vm agupta$ vagrant status
Current machine states:


default                   running (virtualbox)


The VM is running. To stop this VM, you can run `vagrant halt` to
shut it down forcefully, or you can run `vagrant suspend` to simply
suspend the virtual machine. In either case, to restart it again,
simply run `vagrant up`.
abhinavs-Air:centos7-test-vm agupta$ 

10. Connect to CentOS VM

abhinavs-Air:centos7-test-vm agupta$ pwd
/Users/agupta/vagrant_box/centos7-test-vm

abhinavs-Air:centos7-test-vm agupta$ vagrant ssh
-bash: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such file or directory

[vagrant@centos7-test-vm ~]$ sudo su -

[root@centos7-test-vm ~]


Enjoy CentOS VM 😊
