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。
创新互联建站于2013年创立,是专业互联网技术服务公司,拥有项目成都网站制作、做网站、外贸营销网站建设网站策划,项目实施与项目整合能力。我们以让每一个梦想脱颖而出为使命,1280元乐都做网站,已为上家服务,为乐都各地企业和个人服务,联系电话:028-86922220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

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:
config.vm.synced_folder '/host/path', '/guest/path', SharedFoldersEnableSymlinksCreate: false

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。
