Windows下虚拟机的自动化管理-创新互联

Windows下虚拟机的创建主要为VirtualBox和VMWare。本文采用VirtualBox搭建虚拟机，并使用Vagrant对虚拟机进行自动化管理，包括虚拟机的创建，虚拟机初始环境的自动化建设，也包括虚拟机和虚拟机环境重建，虚拟机的销毁等。

在Windows下运行虚拟机首先要确保计算机已经打开了CPU的虚拟机支持，现阶段的PC机CPU都包含对虚拟机的支持，包括Intel和AMD等，我们可以通过打开Windows任务管理器进行核查。

可以看到有一项：虚拟机：已启用，表征该PC机CPU的虚拟机支持功能已经开启，如若不是，则可进入PC机的BIOS开启CPU虚拟机的支持功能，具体操作随不同的PC机有一定的差别。

一 VirtualBox和Vagrant的安装

1 安装VirtualBox

进入Oracle VM VirtualBox网站网站下载Windows版VirtualBox 7.0.4 platform packages（https://download.virtualbox.org/virtualbox/7.0.4/VirtualBox-7.0.4-154605-Win.exe），以及VirtualBox 7.0.4 Oracle VM VirtualBox Extension Pack（https://download.virtualbox.org/virtualbox/7.0.4/Oracle_VM_VirtualBox_Extension_Pack-7.0.4.vbox-extpack），当前版是7.0.4。双击VirtualBox-7.0.4-154605-Win.exe。

2 安装Vagrant

进入Vagrant by HashiCorp (vagrantup.com)网站。下载下载Windows版Vagrant（https://releases.hashicorp.com/vagrant/2.3.3/vagrant_2.3.3_windows_amd64.msi）。双击vagrant_2.3.3_windows_amd64.msi。

在C:\下创建目录vagrant，将来所有vagrant相关命令执行和配置文件都在这一目录下。

cd c:\

c:\>mkdir vagrant

c:\>cd vagrant

c:\vagrant>vagrant --version
Vagrant 2.3.3

下面我们用Vagrant创建、管理虚拟机。

二 使用Vagrant工具创建管理Windows虚拟机

Vagrant是实现虚拟机全生命周期管理的命令行工具。通过面向自动化和简单易用的工作流构建完整开发环境，降低开发环境配置时间，提升从开发到作业的效率，并做到在自己的机器上就能做到。

为什么使用 Vagrant

Vagrant 提供易于配置、可重现和便携的工作环境，该工作环境建立在行业标准技术之上，并由单一一致的工作流程控制，以帮助大限度地提高您和您的团队的生产力和灵活性。 Vagrant 基于前辈的杰出工具，实现这样的超凡能力。可以在 VirtualBox、VMware、AWS 或任何其他提供商之上，并通过诸如 shell 脚本、Chef 或 Puppet 等行业标准配置工具，在虚拟机上自动安装和配置软件。

对于开发人员 如果您是开发人员，Vagrant 会将依赖项及其配置隔离在一个一次性的、一致的环境中，而不会牺牲您习惯使用的任何工具（编辑器、浏览器、调试器等）。 一旦您或其他人创建了一个 Vagrantfile，您只需要启动 vagrant up，一切都已安装和配置好供您使用。 您团队的其他成员从相同的配置创建他们的开发环境，因此无论您是在 Linux、Mac OS X 还是 Windows 上工作，您的所有团队成员都在相同的环境中运行代码，针对相同的依赖项，配置相同方法。 告别“只在我的机器上工作”问题。

对于运维人员 如果您是运维工程师或 DevOps 工程师，Vagrant 为您提供一次性环境和一致的工作流程，用于开发和测试基础架构管理脚本。 您可以使用 VirtualBox 或 VMware 等本地虚拟化快速测试 shell 脚本、Chef Cookbooks、Puppet 模块等。 然后，使用相同的配置，您可以使用相同的工作流程在 AWS 或 RackSpace 等远程云上测试这些脚本。 抛弃您的自定义脚本以回收 EC2 实例，停止向各种机器发送 SSH 提示，并开始使用 Vagrant 让您的生活变得理智。

对于设计师 如果你是一名设计师，Vagrant 会自动设置网络应用程序所需的一切，以便你专注于做你最擅长的事情：设计。 一旦开发人员配置了 Vagrant，您就无需担心如何让该应用程序再次运行。 无需再麻烦其他开发人员来帮助您修复环境以便您可以测试设计。 只需检查代码，vagrant up，然后开始设计。

对于每个人 Vagrant 是为每个人设计的，作为创建虚拟化环境的最简单和最快的方法！

下面测试创建一个Almalinux虚拟机。

在C:\vagrant目录创建vagrantfile。

Vagrant.configure("2") do |config|
  config.vm.box = "bento/almalinux-9"
end

c:\vagrant>vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==>default: Box 'bento/almalinux-9' could not be found. Attempting to find and install...

Vagrant is currently configured to create VirtualBox synced folders with
the `SharedFoldersEnableSymlinksCreate` option enabled. If the Vagrant
guest is not trusted, you may want to disable this option. For more
information on this option, please refer to the VirtualBox manual:

  https://www.virtualbox.org/manual/ch04.html#sharedfolders

This option can be disabled globally with an environment variable:

  VAGRANT_DISABLE_VBOXSYMLINKCREATE=1

or on a per folder basis within the Vagrantfile:

    default:

    default: VirtualBox Version: 7.0
==>default: Mounting shared folders...
    default: /vagrant =>C:/vagrant

从VirtualBox虚拟机管理器可以看到创建的虚拟机已经运行。

通过vagrant ssh可以连接到虚拟机。

c:\vagrant>vagrant ssh

This system is built by the Bento project by Chef Software
More information can be found at https://github.com/chef/bento
[vagrant@localhost ~]$ ls
[vagrant@localhost ~]$ ls /
afs  bin  boot  dev  etc  home  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  vagrant  var
[vagrant@localhost ~]$

也可以通过MobaXterm通过端口2222连接。缺省用户名和密码：vagrant:vagrant。

可以事先将almalinux-9虚拟机镜像（box）从以下地址下载下来：https://app.vagrantup.com/bento/boxes/almalinux-9/versions/202208.18/providers/virtualbox.box

执行vagrant box add：

c:\vagrant>vagrant box add --name almalinux-9 ./almalinux-9.box
==>box: Box file was not detected as metadata. Adding it directly...
==>box: Adding box 'almalinux' (v0) for provider:
    box: Unpacking necessary files from: file://c:/vagrant/almalinux-9.box
    box:
==>box: Successfully added box 'almalinux' (v0) for 'virtualbox'!

c:\vagrant>vagrant box list
almalinux-9         (virtualbox, 0)

修改vagrantfile： 

Vagrant.configure("2") do |config|
  config.vm.box = "almalinux-9"
end

从环境中移除box：

c:\vagrant>vagrant box remove almalinux-9
Removing box 'almalinux-9' (v0) with provider 'virtualbox'...

c:\vagrant>vagrant box list

我们可以看到Vagrant创建虚机机的同时，还为我们创建了一个共享目录/vagrant =>C:/vagrant，将Windows主机的C:\vagrant同虚拟机/vagrant目录同步，方便虚拟机和Windows主机文件共享。

运行的虚拟机通过以下命令操作而进入不同的状态。

vagrant destroy         停止并销毁虚拟机，一般使用vagrant destroy -f强制停止并销毁虚拟机
vagrant halt            停止虚拟机
vagrant reload          重启虚拟机
vagrant suspend         虚拟机挂起
vagrant resume          重新运行虚拟机
vagrant up              使用vagrantfile配置启动虚拟机

三 一步创建多台虚拟机

通过vagrantfile配置，能够一次性创建运行多台虚拟机。让我们修改vagrantfile。

Vagrant.configure("2") do |config|
  config.vm.provider "virtualbox" do |vb|
    # Display the VirtualBox GUI when booting the machine
    #vb.gui = true

    # Customize the amount of memory on the VM:
    vb.memory = "1024"
	# Customize the CPUs used:
	vb.cpus = 2
  end
  
  (1..2).each do |i|
	  config.vm.define "node0#{i}" do |node|
		node.vm.box = "bento/almalinux-9"
		node.vm.hostname = "node0#{i}"
		node.vm.network "private_network", ip: "192.168.99.1#{i}"
		node.vm.synced_folder "share/", "/home/vagrant/share"
	  end
	end
end

c:\vagrant>vagrant destroy -f
==>node02: Discarding saved state of VM...
==>node02: Destroying VM and associated drives...
==>node01: Discarding saved state of VM...
==>node01: Destroying VM and associated drives...

四 为虚拟机安装和配置基础应用及环境

通过Vagrant provision可以为运行的虚拟机安装与配置基础环境。

创建entry point.sh。

#!/bin/bash

sudo dnf install -y wget vim less expect

sudo sed -i 's/^#\(PubkeyAuthentication yes\)/\1/' /etc/ssh/sshd_config
sudo sed -i 's/^#\(PermitRootLogin\) .*/\1 yes/' /etc/ssh/sshd_config
echo "StrictHostKeyChecking no" | sudo tee -a /etc/ssh/ssh_config
ssh-keygen -t rsa -f /home/vagrant/.ssh/id_rsa -P ''
sudo chown -R vagrant:vagrant /home/vagrant/.ssh
#sudo cat /home/vagrant/.ssh/id_rsa.pub >>/home/vagrant/.ssh/authorized_keys

cp /vagrant/sshpub.sh /home/vagrant/
cp /vagrant/hosts.txt /home/vagrant/

cat /home/vagrant/hosts.txt | sudo tee -a /etc/hosts

文件hosts.txt保存分配IP地址与虚拟机主机名的对应关系。

192.168.99.11 node01
192.168.99.12 node02

修改vagrantfile。

Vagrant.configure("2") do |config|
  config.vm.provider "virtualbox" do |vb|
    # Display the VirtualBox GUI when booting the machine
    #vb.gui = true

    # Customize the amount of memory on the VM:
    vb.memory = "1024"
		# Customize the CPUs used:
		vb.cpus = 2
  end
  
  (1..2).each do |i|
	  config.vm.define "node0#{i}" do |node|
			node.vm.box = "bento/almalinux-9"
			node.vm.hostname = "node0#{i}"
			node.vm.network "private_network", ip: "192.168.99.1#{i}"
			node.vm.synced_folder "share/", "/home/vagrant/share"
	  end
	end
	config.vm.provision "shell", path: "entrypoint.sh"

end

五 利用Vagrant trigger实现虚拟机之间的免密登录

定义在虚拟机启动后，通过循环SSH登录彼此，执行ssh-copy-id，实现虚拟机间相互免密登录。

创建虚拟机彼此循环登录的shell脚本，sshloginset.sh。

#!/bin/bash
set -e

# 取得集群的所有主机名，这里需要注意：hosts配置的IP和主机名只能用一个空格分割
# tail -n +2 表示从第2行开始
# cut -d ' ' -f 2 表示用空格分割每一行并获取第2列
hostList=$(cat /home/vagrant/hosts.txt | tail -n +1 | cut -d ' ' -f 2)

#服务器和命令设置
user=vagrant
passwd=vagrant
cmd=/home/vagrant/sshcpid.sh

#ssh登录函数
sshlgset(){
    echo "======>$host ssh in..."
    /usr/bin/expect<

创建虚拟机彼此ssh-copy-id shell脚本。sshcpid.sh。

#!/bin/bash
set -e

# 取得集群的所有主机名，这里需要注意：hosts配置的IP和主机名只能用一个空格分割
# tail -n +2 表示从第2行开始
# cut -d ' ' -f 2 表示用空格分割每一行并获取第2列
hostList=$(cat /home/vagrant/hosts.txt | tail -n +1 | cut -d ' ' -f 2)
logPre=PPK

#服务器密码
user=vagrant
passwd=vagrant

#拷贝公钥函数
sshcopyid(){
    echo "======>$host ssh-copy-id..."
    /usr/bin/expect<

修改vagrantfile，添加trigger代码段。

Vagrant.configure("2") do |config|
  config.vm.provider "virtualbox" do |vb|
    # Display the VirtualBox GUI when booting the machine
    #vb.gui = true

    # Customize the amount of memory on the VM:
    vb.memory = "1024"
		# Customize the CPUs used:
		vb.cpus = 2
  end
  
  (1..2).each do |i|
	  config.vm.define "node0#{i}" do |node|
			node.vm.box = "bento/almalinux-9"
			node.vm.hostname = "node0#{i}"
			node.vm.network "private_network", ip: "192.168.99.1#{i}"
			node.vm.synced_folder "share/", "/home/vagrant/share"
	  end
	end

	config.vm.provision "shell", path: "entrypoint.sh"
	
	config.trigger.after :up do |trigger|
		trigger.name = "trigger"
		trigger.info = "Running a trigger after VMs up!"
		trigger.only_on = "node02"
		trigger.run_remote = {path: "sshloginset.sh"}
	end
end

运行。
