vagrant安装和使用

August 22, 2017 本文有 2388 个字 需要花费 5 分钟阅读

简介

在一次偶然的机会我碰到了vagrant，Vagrant是一个基于Ruby的工具，用于创建和部署虚拟化开发环境，总之简单的说vagrant就是一款管理虚拟机的工具

官网

https://www.vagrantup.com/
一些文档还有镜像可以在官网里找到

安装

安装很简单，只要下载对应的安装包，安装起来就好了，比如我用的是fedora那就下载rpm包，上面写着centos的就是了
下载好后安装
sudo dnf install ./vagrant_1.9.7_x86_64.rpm
接着安装virtualbox
virtualbox的安装和vagrant一样，先下载安装包之后安装就好了

使用

首先添加一个镜像
vagrant box add ubuntu/xenial64
我添加的是ubuntu16.04 64位的虚拟机镜像，具体你想下载什么镜像你可以在
https://app.vagrantup.com/boxes/search?_ga=2.204284501.492827600.1503221431-11326269.1503221431
这个网站里找
出现下面的提示说明镜像添加成功

➜  ~ vagrant box add ubuntu/xenial64
==> box: Loading metadata for box 'ubuntu/xenial64'
    box: URL: https://vagrantcloud.com/ubuntu/xenial64
==> box: Adding box 'ubuntu/xenial64' (v20170815.1.0) for provider: virtualbox
    box: Downloading: https://vagrantcloud.com/ubuntu/boxes/xenial64/versions/20170815.1.0/providers/virtualbox.box
==> box: Box download is resuming from prior download progress
==> box: Successfully added box 'ubuntu/xenial64' (v20170815.1.0) for 'virtualbox'!

之后你可以确认一下镜像是否添加成功

➜  ~ vagrant box list  
ubuntu/xenial64 (virtualbox, 20170815.1.0)

接着创建一个目录来存放Vagrantfile
mkdir bboysoul
cd bboysoul/
初始化，此操作会在当前目录下生成一个Vagrantfile

➜  bboysoul vagrant init ubuntu/xenial64
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.
➜  bboysoul ls
Vagrantfile
➜  bboysoul

接着启动一个虚拟机

➜  bboysoul vagrant up

    default: Guest Additions Version: 5.0.40
    default: VirtualBox Version: 5.1

    default: /vagrant => /home/bboysoul/bboysoul

启动完成之后你可以打开virtualbox，你可以看到一个已经启动完成的虚拟机
接着ssh进去

➜  bboysoul vagrant ssh

ubuntu@ubuntu-xenial:~$

从启动虚拟机的时候的输出信息我们可以看到还挂载了一个共享目录

==> default: Mounting shared folders...
    default: /vagrant => /home/bboysoul/bboysoul

在虚拟机里的路径是/vagrant，实体机的路径是/home/bboysoul/bboysoul
也就是Vagrantfile的所在路径

ubuntu@ubuntu-xenial:~$ ls /vagrant/
Vagrantfile  ubuntu-xenial-16.04-cloudimg-console.log
ubuntu@ubuntu-xenial:~$

接着你可以退出来重启虚拟机
vagrant reload

➜  bboysoul vagrant reload

你可以使用
vagrant halt
来关闭虚拟机

➜  bboysoul vagrant halt

vagrant up
来启动虚拟机

一些常用的命令

可以从vagrant的help来看

➜  bboysoul vagrant list-commands
Below is a listing of all available Vagrant commands and a brief
description of what they do.

box             manages boxes: installation, removal, etc.

现在列举一些常用的

  • vagrant box 用来管理box的
  • vagrant box add 添加一个box
  • vagrant box list 列出可用的box
  • vagrant box remove 删除一个box
  • vagrant box
  • vagrant halt 停止一个虚拟机
  • vagrant init 初始化一个虚拟机
  • vagrant package 打包一个虚拟机
  • vagrant reload 重启一个虚拟机
  • vagrant ssh ssh进虚拟机
  • vagrant up 启动一个虚拟机
  • vagrant status 查看虚拟机状态

打包分发虚拟机

当你把所有的环境都配置好之后，下一步要做的就是打包分发了
一个命令就可以搞定你的打包

➜  bboysoul vagrant package
==> default: Attempting graceful shutdown of VM...
==> default: Clearing any previously set forwarded ports...
==> default: Exporting VM...
==> default: Compressing package to: /home/bboysoul/bboysoul/package.box
➜  bboysoul ls
package.box  ubuntu-xenial-16.04-cloudimg-console.log  Vagrantfile

如显示所示vagrant会把你的虚拟机先关闭再进行打包，之后会在当前目录下生成一个package.box的文件，之后你把这个文件通过网盘或者其他文件共享的方式发给要部署的机器直接部署就好了

高级使用

你会看到我们一直没有说vagrant的配置文件Vagrantfile，这个文件主要配置了虚拟机的配置、SSH配置、Vagrant的一些基础配置。
下面我说一下常见的配置

  • box的名称配置
    config.vm.box = "ubuntu12.04"
  • 同步目录配置
    config.vm.synced_folder "本机地址", "虚拟机文件地址"
  • 主机hostname设置
    config.vm.hostname = "for_work"
  • 端口转发配置
    config.vm.network "forwarded_port", guest: 80, host: 8080

其他的配置文件大家可以参考下面这个网站https://www.vagrantup.com/docs/vagrantfile/

最后说两句

说真的我是真的不知道世界上还有一个系统叫windows，听说用windows的人技术水平都很高，所以我想见识一下。
