➜ vagrant vagrant box add centOs7 /Users/xianbin.yang/Documents/vagrant/centos-7.0-x86_64.box

  box: Unpacking necessary files from: file:///Users/xianbin.yang/Documents/vagrant/centos-7.0-x86_64.box
==> box: Successfully added box 'centOs7' (v0) for 'virtualbox'!

➜ vagrant vagrant init centOs7
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.

➜ vagrant vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'centOs7'...
==> default: Matching MAC address for NAT networking...
==> default: Setting the name of the VM: vagrant_default_1612583375721_1893
==> default: Clearing any previously set forwarded ports...
==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
  default: Adapter 1: nat

  default: SSH address: 127.0.0.1:2222
  default: SSH username: vagrant
  default: SSH auth method: private key
  default:
  default: Vagrant insecure key detected. Vagrant will automatically replace
  default: this with a newly generated keypair for better security.
  default:
  default: Inserting generated public key within guest...
  default: Removing insecure key from the guest if it's present...
  default: Key inserted! Disconnecting and reconnecting using new SSH key...
==> default: Machine booted and ready!
==> default: Checking for guest additions in VM...
  default: The guest additions on this VM do not match the installed version of
  default: VirtualBox! In most cases this is fine, but in rare cases it can
  default: prevent things such as shared folders from working properly. If you see
  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: Guest Additions Version: 4.3.28
