Vagrant(、)是一款构建虚拟开发环境的工具,支持 Window,Linux,Mac OS,Vagrant 中的 Boxes 概念类似于 Docker(实质是不同的),你可以把它看作是一个箱子,里面装了一些东西,Vagrant 创建虚拟机的时候,需要用到 Box ,它里面包含了虚拟机配置、虚拟机硬盘镜像和 Vagrant 配置的压缩包,有了 Box,你不需要再重新下载 ISO 镜像文件、新建虚拟机、修改虚拟机等配置,而是直接运行你所需要的操作系统。

更多 Vagrant 概念,参考:

Vagrant 支撑 VirtualBox、HyperV、VMWare 等虚拟机软件,我 Mac 电脑装的是 VMWare Fusion,但 Vagrant 支持是收费的(79 美元),好黑呀,不过 VirtualBox 是免费的,我又安装了个 VirtualBox(大概 300 M),以便做示例。

使用 Vagrant 的目的,就是方便在虚拟机中做 Consul 的集群()。

安装 Vagrant(使用 )

$ brew install vagrant

安装好 Vagrant 之后,就可以使用初始化 Box 了,你可以使用别人封装好的 Box,也可以自己封装 Box,比如下面命令:

$ vagrant box add ubuntu/trusty64

ubuntu/trusty64是一个公开 Boxes()。运行上面第一行命令后,Vagrant 会在工作目录下创建 Vagrantfile 配置文件。在线下载 Box 会比较慢,你可以先下载 Box 之后,再加载本地的 Box 进行初始化。

我使用的是 Ubuntu 64 Box:,其他 Box 下载地址:

下载好 Box 之后,你可以创建这样的工作目录:

$ tree.├── boxes│   └── precise64.box└── works2 directories, 1 files

创建命令:

$ mkdir vagrant_projects$ mkdir boxes$ mkdir works

然后把下载好的 Box 放到 boxes 文件夹下,然后命令转到 boxes 目录下(cd boxes),然后执行添加 Box 命令:

$ vagrant box add ubuntu precise64.box

添加后之后,可以查看所添加的 Box 列表:

$ vagrant box listubuntu64 (virtualbox, 0)

命令转到 works 目录下(cd works)接着进行初始化虚拟机:

$ vagrant init ubuntu64

初始化完成后,会在当前目录下生成一个 VagrantFile 配置文件,里面是对虚拟机环境的一些配置(可以手动修改),然后启动虚拟机:

$ vagrant upBringing machine 'default' up with 'virtualbox' provider...==> default: Clearing any previously set forwarded ports...==> default: Clearing any previously set network interfaces...==> default: Preparing network interfaces based on configuration...    default: Adapter 1: nat    default: Adapter 2: bridged==> default: Forwarding ports...    default: 22 (guest) => 2222 (host) (adapter 1)==> default: Booting VM...==> default: Waiting for machine to boot. This may take a few minutes...    default: SSH address: 127.0.0.1:2222    default: SSH username: vagrant    default: SSH auth method: private key==> default: Machine booted and ready!==> default: Checking for guest additions in VM...    default: The guest additions on this VM do not match the installed version of    default: VirtualBox! In most cases this is fine, but in rare cases it can    default: prevent things such as shared folders from working properly. If you see    default: shared folder errors, please make sure the guest additions within the    default: virtual machine match the version of VirtualBox you have installed on    default: your host and reload your VM.    default:     default: Guest Additions Version: 4.2.0    default: VirtualBox Version: 5.1==> default: Configuring and enabling network interfaces...==> default: Mounting shared folders...    default: /vagrant => /Users/xishuai/vagrant_project/works==> default: Machine already provisioned. Run `vagrant provision` or use the `--provision`==> default: flag to force provisioning. Provisioners marked to run always will still run.

虚拟机启动好之后(可以在 VirtualBox 中查看是否已启动),就可以登录虚拟机了:

$ vagrant sshWelcome to Ubuntu 12.04 LTS (GNU/Linux 3.2.0-23-generic x86_64) * Documentation:  https://help.ubuntu.com/New release '14.04.5 LTS' available.Run 'do-release-upgrade' to upgrade to it.Welcome to your Vagrant-built virtual machine.Last login: Tue Dec 27 10:16:06 2016 from 10.0.2.2vagrant@precise64:~$

这个命令就表示已经进入了 Ubuntu 的系统,可以像在虚拟机中使用一样使用它了。

当然也可以把你配好的 Box 导出出来,给其他人使用,执行命令:

$ cd ~/VirtualBox\ VMs/works_default_1482820841651_93029$ vagrant package  --output works_default_1482820841651_93029 --base ubuntu64.box

Vagrant 命令列表:

  • vagrant box list:查看box列表
  • vagrant add box box 名字 box地址:添加box,自动帮你生成 Vagrantfile
  • vagrant init box 名字:初始化 Vagrantfile
  • vagrant up:启动虚拟机
  • vagrant ssh:连接虚拟机
  • vagrant halt:关闭虚拟机
  • vagrant reload:重新加载 Vagrantfile 文件
  • vagrant suspend:暂时挂起虚拟机
  • vagrant destroy:销毁虚拟机
  • vagrant status:查看虚拟机运行状态
  • vagrant package:导出 Box

在使用 Vagrant 的时候,遇到了这样一个问题:创建的 Ubuntu 虚拟机,需要访问外部网络,所以需要将虚拟机的网络模式设置为桥接模式(Bridged),于是就使用 VirtualBox 进行设置,但设置成功之后,每次 Vagrant 启动虚拟机的时候,都会进行网络模式重置,但如果用 VirtualBox 启动的话,就没有什么问题。

这个问题搞了好久,最后的解决方案是修改 Vagrantfile 配置文件,添加如下配置:

config.vm.network "public_network", bridge: "en0: Wi-Fi (AirPort)"config.vm.boot_timeout = 20

boot_timeout是链接超时设置(20 秒),bridge后面表示桥接的网络模式(WiFi 网络),如果不进行设置的话,每次启动虚拟机的时候,会进行选择网络模式:

$ vagrant upBringing machine 'default' up with 'virtualbox' provider...==> default: Clearing any previously set forwarded ports...==> default: Clearing any previously set network interfaces...==> default: Specific bridge 'en1: Wi-Fi (AirPort)' not found. You may be asked to specify==> default: which network to bridge to.==> default: Available bridged network interfaces:1) en0: Wi-Fi (AirPort)2) en1: Thunderbolt 13) en2: Thunderbolt 24) p2p05) awdl06) bridge07) vmnet18) vmnet8==> default: When choosing an interface, it is usually the one that is==> default: being used to connect to the internet.    default: Which interface should the network bridge to?

由于之前的 Ubuntu 版本太低(12.04),安装 .NET Core 的时候,遇到了一些问题,后来又换了一个 (版本 14.04),但配置的时候,又遇到了下面问题:

$ vagrant init ubuntu_server1A `Vagrantfile` has been placed in this directory. You are nowready to `vagrant up` your first virtual environment! Please readthe comments in the Vagrantfile as well as documentation on`vagrantup.com` for more information on using Vagrant.xishuaideMacBook-Pro:ubuntu_server1 xishuai$ vagrant upBringing machine 'default' up with 'virtualbox' provider...==> default: Importing base box 'ubuntu_server1'...==> default: Matching MAC address for NAT networking...==> default: Setting the name of the VM: ubuntu_server1_default_1482924693668_66404==> default: Clearing any previously set network interfaces...==> default: Preparing network interfaces based on configuration...    default: Adapter 1: nat==> default: Forwarding ports...    default: 22 (guest) => 2222 (host) (adapter 1)==> default: Booting VM...==> default: Waiting for machine to boot.

This is usuallybecause the filesystem "vboxsf" is not available. This filesystem ismade available via the VirtualBox Guest Additions and kernel module.Please verify that these guest additions are properly installed in theguest. This is not a bug in Vagrant and is usually caused by a faultyVagrant box. For context, the command attempted was:mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrantThe error output from the command was:mount: unknown filesystem type 'vboxsf'

解决方案(参考 ):

$ vagrant plugin install vagrant-vbguest

另外,附一些 Linux 常用命令:

  • command &:将进程放在后台执行
  • ctrl + z:暂停当前进程 并放入后台
  • jobs:查看当前后台任务
  • bg( %id):将任务转为后台执行
  • fg( %id):将任务调回前台
  • kill( %id):杀掉任务
