vagrant用於建立和部署虛擬化開發環境。以下是在ubuntu系統上進行操作

1.vagrant 安裝

   apt-get install vagrant ----安裝agrant

   vagrant box add   puppetlabs/ubuntu-14.04-64-nocm ----新增vagrant box

   apt-get install virtualbox-5.1 ----安裝virtualbox，vagrant是通過virtual/vm進行虛擬機器建立的

安裝遇到的問題：

  （1）apt-get intall vagrant安裝的版本比較老

  解決辦法：從官網上下載最新版本的agrant進行安裝，下載地址：https://www.vagrantup.com/downloads.html

  （2）vagrant box add命令會主動從網路上下載需要的box，但是會比較慢，而且時間長了就中斷，需要重新下

 解決辦法：找到對應的vagrant box檔案，下載到本地安裝。下載地址：https://vagrantcloud.com/puppetlabs/boxes/ubuntu-14.04-64-nocm/versions/1.0.3/providers/virtualbox.box

2.vagrant配置檔案

以我本地的配置檔案為例，通過vagrant同時建立三臺虛擬機器

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|
    (1..3).each do |i|
        config.vm.define "vpp#{i}" do |node|
          # Pick the right distro and bootstrap, default is ubuntu1404

          node.vm.box = "puppetlabs/ubuntu-14.04-64-nocm"
          #node.vm.hostname="node#{i}"
          node.vm.box_check_update = false

          homedir = File.expand_path("~/")
          Dir["#{homedir}/.gnupg/**/*"].each do |fname|
            if File.file?(fname)
              destname = fname.sub(Regexp.escape("#{homedir}/"),'')
              node.vm.provision "file", source: fname, destination: destname
            end
          end

          # Copy in the .gitconfig if it exists
          if File.file?(File.expand_path("~/.gitconfig"))
            node.vm.provision  "file", source: "~/.gitconfig", destination: ".gitconfig"
          end

          # vagrant-cachier caches apt/yum etc to speed subsequent
          # vagrant up
          # to enable, run
          # vagrant plugin install vagrant-cachier
          #
          if Vagrant.has_plugin?("vagrant-cachier")
            node.cache.scope = :box
          end

          # Define some physical ports for your VMs to be used by DPDK
          nics = (ENV['VPP_VAGRANT_NICS'] || "4").to_i(10)
          for i in 1..nics
            node.vm.network "private_network", type: "dhcp"
          end

          # use http proxy if avaiable
          if ENV['http_proxy'] && Vagrant.has_plugin?("vagrant-proxyconf")
           node.proxy.http     = ENV['http_proxy']
           node.proxy.https    = ENV['https_proxy']
           node.proxy.no_proxy = "localhost,127.0.0.1"
          end

          vmcpu=(ENV['VPP_VAGRANT_VMCPU'] || 2)
          vmram=(ENV['VPP_VAGRANT_VMRAM'] || 4096)

          node.ssh.forward_agent = true

          node.vm.synced_folder "../../", "/vpp", disabled: false

          node.vm.provider "virtualbox" do |vb|
              vb.customize ["modifyvm", :id, "--ioapic", "on"]
              vb.memory = "#{vmram}"
              vb.cpus = "#{vmcpu}"

              #support for the SSE4.x instruction is required in some versions of VB.
              vb.customize ["setextradata", :id, "VBoxInternal/CPUM/SSE4.1", "1"]
              vb.customize ["setextradata", :id, "VBoxInternal/CPUM/SSE4.2", "1"]
          end
        end  
    end
end

3.vagrant常用命令

  vagrant up ----建立並啟動虛擬機器

  vagrant status ----檢視虛擬機器狀態

  vagrant ssh ----登入虛擬機器

  vagrant destroy ----刪除虛擬機器

  vagrant reload ----修改vagrantfile後重新載入
