虚机安装

Vagrant创建虚机

方式一

• 创建目录：mkdir centos7

• 初始化Vagrantfile文件：vagrant init centos/7

• 创建虚机：vagrant up

方式二

• 下载一个合适的box。下载地址如下

  下载方式一：vagrant官网下载镜像方式

  下载方式二：http://cloud.centos.org/centos/7/vagrant/x86_64/images/

  下载方式三：https://www.vagrantbox.es/

• 建立了如下的开发环境目录：

  $ /Users/helei/vagrant
  $ cd /Users/helei/vagrant

• 完成一个box的安装

  $ vagrant box add {title} {url}
  $ vagrant init {title}
  $ vagrant up

  vagrant box add 是添加box的命令

  其中｛title｝可以自行设置，我这里使用的是 centos7 ，｛url｝是下载到本地box路径。我的路径是：/Users/helei/vagrant/centos-7.0-x86_64.box

  # 安装box
  $ vagrant box add CentOs7 /Users/helei/vagrant/centos-7.0-x86_64.box

  输出内容：

  Downloading or copying the box...
  Extracting box...te: 47.5M/s, Estimated time remaining: --:--:--)
  Successfully added box 'base' with provider 'virtualbox'!

  box中的镜像文件被放到了：/Users/helei/.vagrant.d/boxes/，如果在window系统中应该是放到了： C:\Users\当前用户名.vagrant.d\boxes\目录下。

  # 如果是才add 的box，就必须执行本步骤，初始化一次后，以后启动系统，就不需要执行本步骤。
  $ vagrant init CentOs7

  输出内容：

  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.

  这样就会在当前目录生成一个 Vagrantfile的文件，里面有很多配置信息，后面我在慢慢说，默认不做任何配置改动，也是可以启动系统的。

  # 启动系统
  $ vagrant up

  输出内容：

  Bringing machine 'default' up with 'virtualbox' provider...
  [default] Importing base box 'base'...
  [default] Matching MAC address for NAT networking...
  [default] Setting the name of the VM...
  [default] Clearing any previously set forwarded ports...
  ...

Vagrant基本操作

• 启动虚机：vagrant up

• 查看虚机状态：vagrant status

• 显示当前用户Vagrant的所有环境状态：vagrant global-status

• 进入虚机：vagrant ssh docker-node1

• 删除虚机：vagrant destroy [name|id]
