2.下载Vagrant并安装：
https://releases.hashicorp.com/vagrant/2.0.4/vagrant_2.0.4_x86_64.msi
3.在任意空目录下通过Vagrant初始化Centos7

vagrant init centos/7
出现以下则表示初始化成功：
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.

4.安装Centos7并启动

vagrant up
出现以下内容则表示安装并启动成功：
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'centos/7'...
==> default: Matching MAC address for NAT networking...
==> default: Checking if box 'centos/7' is up to date...
==> default: Setting the name of the VM: docker-node1_default_1524538386737_11529
==> default: Fixed port collision for 22 => 2222. Now on port 2200.
==> default: Clearing any previously set network interfaces...

    default: SSH address: 127.0.0.1:2200
    default: SSH username: vagrant
    default: SSH auth method: private key
    default:

==> default: Checking for guest additions in VM...
    default: No guest additions were detected on the base box for this VM! Guest
    default: additions are required for forwarded ports, shared folders, host only
    default: networking, and more. If SSH fails on this machine, please install
    default: the guest additions and repackage the box to continue.

5.SSH连接并进入虚拟机：

vagrant ssh
出现以下命令行则表示连接成功：
[vagrant@localhost ~]$
这就已经连接到Centos下，可以进行相关操作了。
