Vagrant的几个命令：
vagrant box add 添加box的操作vagrant init 初始化box的操作vagrant up 启动虚拟机的操作vagrant ssh 登录拟机的操作Vagrant还包括如下一些操作：
vagrant box list
显示当前已经添加的box列表
$ vagrant box list
base (virtualbox)
vagrant box remove
删除相应的box
$ vagrant box remove base virtualbox
Removing box ‘base‘ with provider ‘virtualbox‘...
vagrant destroy
停止当前正在运行的虚拟机并销毁所有创建的资源
$ vagrant destroy
Are you sure you want to destroy the ‘default‘ VM? [y/N] y
[default] Destroying VM and associated drives...
vagrant halt
关机
$ vagrant halt
[default] Attempting graceful shutdown of VM...
vagrant package
打包命令，可以把当前的运行的虚拟机环境进行打包

[default] Exporting VM...
[default] Compressing package to: /Users/astaxie/vagrant/package.box
vagrant plugin
用于安装卸载插件
vagrant provision
通常情况下Box只做最基本的设置，而不是设置好所有的环境，因此Vagrant通常使用Chef或者Puppet来做进一步的环境搭建。那么Chef或者Puppet称为provisioning，而该命令就是指定开启相应的provisioning。按照Vagrant作者的说法，所谓的provisioning就是"The problem of installing software on a booted system"的意思。除了Chef和Puppet这些主流的配置管理工具之外，我们还可以使用Shell来编写安装脚本。
例如： vagrant provision --provision-with chef
vagrant reload
重新启动虚拟机，主要用于重新载入配置文件
$ vagrant reload

vagrant status
获取当前虚拟机的状态
$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`.
vagrant suspend
挂起当前的虚拟机
$ vagrant suspend
[default] Saving VM state and suspending execution...
前面这些单主机单虚拟机主要是用来自己做开发机，从这部分开始的内容主要将向大家介绍如何在单机上通过虚拟机来打造分布式造集群系统。这种多机器模式特别适合以下几种人：
Vagrant支持单机模拟多台机器，而且支持一个配置文件Vagrntfile就可以跑分布式系统。
现在我们来建立多台VM跑起來，並且让他们之间能够相通信，假设一台是应用服务器、一台是DB服务器，那么这个结构在Vagrant中非常简单，其实和单台的配置差不多，你只需要通过config.vm.define来定义不同的角色就可以了，现在我们打开配置文件进行如下设置：
Vagrant.configure("2") do |config|
config.vm.define :web do |web|
web.vm.provider "virtualbox" do |v|
v.customize ["modifyvm", :id, "--name", "web", "--memory", "512"]
end
web.vm.box = "base"
web.vm.hostname = "web"
web.vm.network :private_network, ip: "11.11.1.1"
end
config.vm.define :db do |db|
db.vm.provider "virtualbox" do |v|
v.customize ["modifyvm", :id, "--name", "db", "--memory", "512"]
end
db.vm.box = "base"
db.vm.hostname = "db"
db.vm.network :private_network, ip: "11.11.1.2"
end
end
这里的设置和前面我们单机设置配置类似，只是我们使用了:web以及:db分別做了两个VM的设置，并且给每个VM设置了不同的hostname和IP，设置好之后再使用vagrant up将虚拟机跑起来：
$ vagrant up
Bringing machine ‘web‘ up with ‘virtualbox‘ provider...
Bringing machine ‘db‘ up with ‘virtualbox‘ provider...
[web] Setting the name of the VM...
[web] Clearing any previously set forwarded ports...
[web] Creating shared folders metadata...
[web] Clearing any previously set network interfaces...
[web] Preparing network interfaces based on configuration...
[web] Forwarding ports...
[web] -- 22 => 2222 (adapter 1)

[db] Creating shared folders metadata...

[db] -- 22 => 2200 (adapter 1)

[db] VM booted and ready for use!
[db] Setting hostname...
[db] Configuring and enabling network interfaces...
[db] Mounting shared folders...
[db] -- /vagrant
看到上面的信息输出后，我们就可以通过vagrant ssh登录虚拟机了，但是这次和上次使用的不一样了，这次我们需要指定相应的角色，用来告诉ssh你期望连接的是哪一台：
$ vagrant ssh web
vagrant@web:~$
$ vagrant ssh db
vagrant@db:~$
是不是很酷！现在接下来我们再来验证一下虚拟机之间的通信，让我们先使用ssh登录web虚拟机，然后在web虚拟机上使用ssh登录db虚拟机(默认密码是vagrant)：
$ vagrant ssh web

通过上面的信息我们可以看到虚拟机之间通信是畅通的，所以现在开始你伟大的架构设计吧，你想设计怎么样的架构都可以，唯一限制你的就是你主机的硬件配置了。
