## 环境准备 ##

### 下载virtualbox ###

https://download.virtualbox.org/virtualbox/6.1.10/VirtualBox-6.1.10-138449-Win.exe

### 下载Vagrant ###

https://releases.hashicorp.com/vagrant/2.2.9/vagrant_2.2.9_x86_64.msi

### 初始化Vagrantfile ###

vagrant init centos/7

`注意本地下载镜像慢，将virtualbox.box路径复制，借助迅雷，将镜像下载到本地，通过本地镜像安装系统。`

![downloading][]

### 将Vagrantfile指向本地 ###

vagrant init box boxName 本地Box路径

#### 创建三台虚拟机Vagrantfile文件 ####

Vagrant.configure("2") do |config|
       (1..3).each do |i|
            config.vm.define "k8s-node#{i}" do |node|
                # 设置虚拟机的Box
                node.vm.box = "./CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box"
    
                # 设置虚拟机的主机名
                node.vm.hostname="k8s-node#{i}"
    
                # 设置虚拟机的IP(public_network：桥接 private_network：仅主机)
                node.vm.network "public_network", ip: "192.168.56.#{99+i}", netmask: "255.255.255.0"
    
                # 设置主机与虚拟机的共享目录
                # node.vm.synced_folder "~/Documents/vagrant/share", "/home/vagrant/share"
    
                # VirtaulBox相关配置
                node.vm.provider "virtualbox" do |v|
                    # 设置虚拟机的名称
                    v.name = "k8s-node#{i}"
                    # 设置虚拟机的内存大小
                    v.memory = 4096
                    # 设置虚拟机的CPU个数
                    v.cpus = 2
                end
            end
       end
    end

### vmware: ###

Vagrant.configure("2") do |config|

                    #v.name = "k8s-node#{i}"
                    # 设置虚拟机的内存大小
                    v.memory = 2048
                    # 设置虚拟机的CPU个数
                    v.cpus = 2
                    v.gui = true
