初始化介绍

1）安装vagrant

2）安装Centos7

$ vagrant init centos/7
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.

　　

执行完上面的命令后，会在用户的家目录下生成Vagrantfile文件。

$ vagrant up

下载镜像过程比较漫长，也可以采用先用下载工具下载到本地后，然后使用“ vagrant box add ”添加，再“vagrant up”即可

#将下载的镜像添加到virtualBox中
$ vagrant box add centos/7 E:\迅雷下载\CentOS-7-x86_64-Vagrant-1905_01.VirtualBox.box
==> box: Box file was not detected as metadata. Adding it directly...
