windows 下使用vargant 搭建虚拟机服务

使用vagrant
下载
vagrant[https://www.vagrantup.com/downloads.html]
下载管理工具VirtualBox[https://www.virtualbox.org/wiki/Downloads]
分别安装这两个
安装好后，可能还须要你安装一些组件，按照提示进行安装便可
vagrant plugin repair
vagrant plugin expunge --reinstall

在本地找一个新建一个文件夹，没有路径要求[C:\APP\HashiCorp\vm1]
在文件夹目录下cmd
第一次的第一个虚拟机须要执行镜像下载
什么版本，能够本身找
ubuntu
vagrant box add https://mirrors.huaweicloud.com/ubuntu-cloud-images/bionic/20200107/bionic-server-cloudimg-amd64-vagrant.box --name ubuntuvm4/bionic64
或者加载本地已经下载好的
vagrant box add C:\APPS\OnlyOne\mega\开发工具\HADOOP\cloud\ubuntu_cloud\bionic-server-cloudimg-amd64-vagrant.box --name ubuntu/bionic64
centos
vagrant box add https://mirrors.nju.edu.cn/centos-cloud/centos/7/vagrant/x86_64/images/CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box --name centos7/bionic64
源连接可能会失效，若是失效，本身再找，通常就是华为源，清华源，阿里源
华为源，https://mirrors.huaweicloud.com/
清华源，https://mirrors.tuna.tsinghua.edu.cn/
南京大学源，https://mirrors.nju.edu.cn/
阿里源，http://mirrors.aliyun.com/
找不到就在里面疯狂找

初始化，ubuntu/bionic64为你上方设置的title

vagrant init ubuntu/bionic64
这时会在对应文件夹下生成一个Vagrantfile的文件。

默认不配置，是单个虚拟机
配置多机的设置

servers = {
    :hadoop1 => '192.168.2.220',
    :hadoop2 => '192.168.2.221',
    :hadoop3 => '192.168.2.222',
    :hadoop4 => '192.168.2.223'
} 

第一种批量循环建立，分配的资源同样
Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/bionic64"
  config.vm.box_check_update = false

  servers.each do |server_name, server_ip|
    config.vm.define server_name do |server_config|
	  server_config.vm.hostname = "#{server_name.to_s}"
	  server_config.vm.network :private_network, ip: server_ip
	  server_config.vm.provider "virtualbox" do |vb|
	    vb.name = server_name.to_s
		  vb.memory = "1024"
		  vb.cpus = 1
	    end
    end
  end
end

第二种 为每一个主机单独做配置

Vagrant.configure("2") do |config|
  config.vm.define "vagrant1" do |vb|
      config.vm.provider "virtualbox" do |v|
      v.memory = 512
      v.cpus = 1
    end
  vb.vm.host_name = "vagrant1"
  vb.vm.network :public_network, ip: "10.0.2.16"
  vb.vm.box = "centos72"
  end

  config.vm.define "vagrant2" do |vb|
    config.vm.provider "virtualbox" do |v|
      v.memory = 512
      v.cpus = 1
    end
  vb.vm.host_name = "vagrant2"
  vb.vm.network :public_network, ip: "10.0.2.16"
  vb.vm.box = "centos72"
  end

  config.vm.define "vagrant3" do |vb|
    config.vm.provider "virtualbox" do |v|
      v.memory = 512
      v.cpus = 1
    end
  vb.vm.host_name = "vagrant3"
  vb.vm.network :public_network, ip: "10.0.2.16"
  vb.vm.box = "centos72"
  end
end

虚拟机默认磁盘10G，若是须要修改磁盘空间
先执行安装磁盘插件 vagrant plugin install vagrant-disksize
而后配置你想要分配的空间

config.vm.box = "ubuntu/bionic64"
  config.vm.box_check_update = false
  config.disksize.size = '50GB'

执行启动
vagrant up hadoop4 启动，根据主机名启动 不跟主机名全启动
vagrant halt hadoop4 关机，根据主机名关机 不跟主机名全关

若是配置完，启动报错 CPU虚拟化没开启，须要进到bios
VisualBox报VT-x is disabled in the BIOS. (VERR_VMX_MSR_VMXON_DISABLED)
thinkpad重启F1进入BIOS，选择:
Sercurity => Virtualization=>Enable
若是报错
error: Could not find Host Interface Networking driver! Please reinstall
这是由于，你以前确定卸载过虚拟机的虚拟网卡，因此这里找不到，那么须要重装虚拟网卡，以下
能够在安装virtualbox目录../Oracle VM VirtualBox中的 drivers\ network\ netadp6目录下有三个文件

VBoxNetAdp6.cat
VBoxNetAdp6.inf
VBoxNetAdp6.sys

这就是virtualbox虚拟网卡的驱动，右击VBoxNetAdp6.inf，点安装便可,安装完成后
从新 vagrant up　就可成功了。

默认用户：vagrant
密钥路径在 C:\APP\HashiCorp\vm1.vagrant\machines\hadoop1\virtualbox\下private_key文件
全部的配置都在：
C:\APP\HashiCorp\vm1\Vagrantfile 文件上
使用 vagrant 帐户和密钥文件登陆
建立root密码

vagrant@hadoop2:~$ sudo su
	root@hadoop2:/home/vagrant# passwd root
	Enter new UNIX password: 
	Retype new UNIX password: 
	passwd: password updated successfully
	root@hadoop2:/home/vagrant#

修改
vim /etc/ssh/sshd_config
将如下参数改成yes 容许

PermitRootLogin yes
PasswordAuthentication yes

重启sshd
systemctl restart sshd
这样才能够直接使用root进行登录

Vagrantfile 文件完整配置以下
