• 超详细的 Vagrant 上手指南
• 使用vagrant搭建hadoop环境

第一篇文章是Vagrant的详细用法介绍，第二篇文章是Vagrant搭建4个虚拟机节点的具体操作。

1.下载

下载CentOS镜像，我选择的是CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box
下载Vagrant，Vagant 网站
下载VirtualBox，VirtualBox 主页

2.创建虚拟机

1. vagrant添加镜像
   ```cmd
   // 查看vagrant版本号
   C:\Users\itlgl>vagrant -v
   Vagrant 2.2.18

// 查看box列表
C:\Users\itlgl>vagrant box list
There are no installed boxes! Use vagrant box add to add some.

// 添加本地box
C:\Users\itlgl>vagrant box add C:\itlgl\hadoop\安装包\CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box –name centos-7
==> box: Box file was not detected as metadata. Adding it directly…
==> box: Adding box ‘centos-7’ (v0) for provider:
box: Unpacking necessary files from: file:///C:/itlgl/hadoop/%B0%B2%D7%B0%B0%FC/CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box
box:
==> box: Successfully added box ‘centos-7’ (v0) for ‘virtualbox’!

C:\Users\itlgl>vagrant box list
centos-7 (virtualbox, 0)

  
2. vagrant安装vagrant-hostmanager插件  
```cmd  
C:\itlgl\hadoop\vm1>vagrant plugin list  
No plugins installed.  
  
C:\itlgl\hadoop\vm1>vagrant plugin install vagrant-hostmanager  
Installing the 'vagrant-hostmanager' plugin. This can take a few minutes...  
Fetching vagrant-hostmanager-1.8.9.gem  
Installed the plugin 'vagrant-hostmanager (1.8.9)'!  

1. 新建vagrant配置文件
   本地创建目录C:\itlgl\hadoop\vm1，用于存放vagrant新的虚拟机配置
   在vm1文件夹内创建init.sh和Vagrantfile

Vagrantfile文件内容：

Vagrant.configure("2") do |config|  
    config.vm.define :master1, primary: true do |master|  
        master.vm.provider "virtualbox" do |v|  
			v.customize ["modifyvm", :id, "--name", "hadoop-master1", "--memory", "1024"]  
       end  
       master.vm.box = "centos-7"  
       master.vm.hostname = "hadoop-master1"  
       master.vm.network :private_network, ip: "192.168.10.10"  
    end  
  
   (1..3).each do |i|  
    config.vm.define "slave#{i}" do |node|  
        node.vm.box = "centos-7"  
        node.vm.hostname = "hadoop-slave#{i}"  
        node.vm.network :private_network, ip: "192.168.10.1#{i}"  
        node.vm.provider "virtualbox" do |vb|  
          vb.customize ["modifyvm", :id, "--name", "hadoop-slave#{i}", "--memory", "1024"]  
        end  
     end  
   end  
  
  #manage hosts file   
  config.hostmanager.enabled = true  
  config.hostmanager.manage_host = true  
  config.hostmanager.manage_guest = true  
  
   #provision  
   config.vm.provision "shell", path: "init.sh", privileged: false  
end  

init.sh文件内容：

sudo yum install -y epel-release  
  
sudo yum install -y  lrzsz.x86_64  
sudo yum install -y nmap-ncat.x86_64  
sudo yum install -y net-tools  
sudo yum install -y vim-enhanced.x86_64  
sudo yum install -y sshpass  
  
sudo yum install -y java-1.8.0-openjdk-devel  

1. vagrant启动虚拟机

   C:\itlgl\hadoop\vm1>vagrant up  
   Bringing machine 'master1' up with 'virtualbox' provider...  
   Bringing machine 'slave1' up with 'virtualbox' provider...  
   Bringing machine 'slave2' up with 'virtualbox' provider...  
   Bringing machine 'slave3' up with 'virtualbox' provider...  
   ==> master1: Importing base box 'centos-7'...  
   ==> master1: Matching MAC address for NAT networking...  
   ...省略一大波日志...  
   

2. 每个虚拟机配置ssh登录
   在VirtualBox管理界面内依次登录虚拟机，用户名密码都是vagrant，vim /etc/ssh/sshd_config，修改如下配置为yes

   PubkeyAuthentication yes  
   PasswordAuthentication yes  
   

3. 使用putty登录hadoop-master1机器
   vagrant ssh-config命令可以查看master1虚拟机的IdentityFile路径，使用putty-gen load加载私钥文件，转为ppk文件存储到本地

putty设置项：

• Session名称：hadoop-master1
• ip： 192.168.10.10
• port： 22
• Connection->Data=>Auto-login username： vagrant
• Connection->SSH->Auth=>Private key file for authentication： 选择刚才的ppk文件
• 桌面复制putty快捷方式，编辑属性=>目标： "C:\Program Files\PuTTY\putty.exe" -load hadoop-master1，双击即可快捷登录
