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，可能还需要你安装一些组件，按照提示进行安装即可

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需要执行镜像下载

什么版本，可以自己找

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

源链接可能会失效，如果失效，自己再找，一般就是华为源，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'

} 

第一种批量循环创建，分配的资源一样

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

第二种为每个主机单独作配置

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，如果需要修改磁盘空间

先执行安装磁盘插件 vagrant plugin install vagrant-disksize

然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

如果配置完，启动报错 CPU虚拟化没开启，需要进到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

如果报错

error: Could not find Host Interface Networking driver! Please reinstall

这是因为，你之前肯定卸载过虚拟机的虚拟网卡，所以这里找不到，那么需要重装虚拟网卡，如下

可以在安装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，点安装即可,安装完成后

重新 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

所有的配置都在：

C:\APP\HashiCorp\vm1\Vagrantfile 文件上

使用 vagrant 账户和密钥文件登录

创建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

将以下参数改为yes 允许

PermitRootLogin yes

PasswordAuthentication yes

重启sshd

systemctl restart sshd

这样才可以直接使用root进行登陆

Vagrantfile 文件完整配置如下
