一、VirtualBox和vagrant的安装
VirtualBox 是一款开源的虚拟机软件，和VMWare是同类型的软件，用于在当前的电脑上构建一台虚拟机，在这台虚拟机上可以安装系统和软件，与真实的电脑一般无二。
Vagrant用于创建和部署虚拟化开发环境。它使用Oracle的开源VirtualBox虚拟化系统.。
注意的是这两个的版本，如果匹配不上在运行vagrant命令时就会出现版本问题，笔者使用的是windows7系统，这里提供上面两个安装包的百度云的地址：
1、VirtualBox

（一）VirtualBox的安装
1、下载完毕后如下
2、点击安装
不需要改变什么，只需要按照步骤，一直next进行安装即可。
（二）Vagrant的安装
1、下载后如下
2、点击安装
这与VirtualBox的安装一样，只是不断的next就可以进行安装完毕，这个安装完毕后会进行重启电脑，在重启电脑后可以打开cmd命令行窗口进行验证看是否已经可以使用了。
可以看到并没有出现什么问题，可以正常的使用了，下面是vagrant对应的命令。
Usage: vagrant [options] <command> [<args>] -v, --version Print the version and exit. -h, --help Print this help. Common commands: box manages boxes: installation, removal, etc. connect connect to a remotely shared Vagrant environment destroy stops and deletes all traces of the vagrant machine global-status outputs status Vagrant environments for this user halt stops the vagrant machine help shows the help for a subcommand init initializes a new Vagrant environment by creating a Vagrant file login log in to HashiCorp's Atlas package packages a running vagrant environment into a box plugin manages plugins: install, uninstall, update, etc. port displays information about guest port mappings powershell connects to machine via powershell remoting provision provisions the vagrant machine push deploys code in this environment to a configured destinatio n rdp connects to machine via RDP reload restarts vagrant machine, loads new Vagrantfile configurati on resume resume a suspended vagrant machine share share your Vagrant environment with anyone in the world snapshot manages snapshots: saving, restoring, etc. ssh connects to machine via SSH ssh-config outputs OpenSSH valid configuration to connect to the machi ne status outputs status of the vagrant machine suspend suspends the machine up starts and provisions the vagrant environment validate validates the Vagrantfile version prints current and latest Vagrant version
二、创建虚拟机
（一）使用Vagrant创建centos虚拟机
1、新建文件夹
可以先创建一个文件夹，比如centos7：
2、Vagrant创建虚拟机
- 下载box
box就是我们需要安装的虚拟机操作系统，Vagrant开源社区提供了许多已经打包好的操作系统：
官方镜像：https://vagrantcloud.com/boxes/search
第三方仓库：http://www.vagrantbox.es/
当从这上面下载box后，将其拷贝到上述新建文件夹中，如下所示：
- vagrant box add --name base vagrant-centos-7.box
将下载好的box通过下面命令进行添加：
- vagrant box list
查看是否添加成功
- vagrant init base
在命令行下进入到该目录，然后执行
vagrant init base
此时会在该目录下生成一个Vagrantfile这样的一个文件，它是对你将要创建的虚拟机的一个描述信息

- vagrant up
启动虚拟机
3、连接虚拟机
其实当你创建好虚拟机后，在你的VirtureBox中已经有这个虚拟机的信息了。
此时你直接点击登陆即可，默认的用户名和密码是：vagrant
或者你也可以通过xshell进行连接，这些都是可以的。
