停止和重启虚拟机


本文档介绍如何手动停止和重启虚拟机实例,以及如何重置或重新启动虚拟机。

  • 如果您不再使用虚拟机或者想要修改其一个或多个属性,请停止该虚拟机;例如,如果要重命名虚拟机、更改其机器类型、添加或移除挂接的磁盘,或者更改满足最低要求的 CPU 平台。停止虚拟机后,请通过重启恢复工作负载;如果您不再需要虚拟机,请将其删除。

  • 重置虚拟机,例如虚拟机无响应或客机操作系统 (OS) 崩溃。重置虚拟机后,您可以恢复工作负载。

  • 例如,如果要擦除虚拟机的内存并将其重新初始化为原始启动状态,请从客机操作系统中重新启动虚拟机。从客机操作系统内部重新启动虚拟机后,您可以恢复工作负载。

准备工作

  • 设置身份验证(如果尚未设置)。身份验证是通过其进行身份验证以访问 Google Cloud 服务和 API 的过程。如需从本地开发环境运行代码或示例,您可以按如下方式向 Compute Engine 进行身份验证。

所需的角色

如需获得停止和重启虚拟机所需的权限,请让管理员向您授予项目的 Compute Instance Admin (v1) (roles/compute.instanceAdmin.v1) IAM 角色。 如需详细了解如何授予角色,请参阅管理访问权限

此预定义角色包含停止和重启虚拟机所需的权限。如需查看所需的确切权限,请展开所需权限部分:

所需权限

如需停止和重启虚拟机,您需要具备以下权限:

  • 停止虚拟机:虚拟机的 compute.instances.stop 权限
  • 从客机操作系统内部停止虚拟机:虚拟机的 compute.instances.setMetadata 权限(如果虚拟机使用实例级 SSH 公钥)。
  • 重启虚拟机:虚拟机的 compute.instances.start 权限
  • 重启使用加密密钥的虚拟机:虚拟机的 compute.instances.startWithEncryptionKey 权限
  • 重置虚拟机:虚拟机的 compute.instances.reset 权限
  • 如需从客机操作系统内部重新启动虚拟机:虚拟机的 compute.instances.setMetadata 权限

您也可以使用自定义角色或其他预定义角色来获取这些权限。

停止虚拟机

停止正在运行的虚拟机时,会发生以下情况:

  1. Compute Engine 会将 ACPI 关停信号发送到虚拟机,并等待一小段时间,以便客机操作系统执行彻底关闭。Compute Engine 随后先将虚拟机状态设置为 STOPPING,然后在一分钟内将其转换为 TERMINATED

  2. 虚拟机会重置为开机状态,并保留其内部 IP、MAC 地址、配置设置和元数据。但是,虚拟机会失去其内存中数据和虚拟机状态。如果您需要保留内存中数据和虚拟机状态,请改为暂停虚拟机

此外,如果您将任何资源挂接到虚拟机,则在您手动分离资源或删除虚拟机之前,这些资源会保持挂接状态。如果虚拟机挂接了任何本地 SSD 磁盘,则默认情况下,停止虚拟机时会舍弃本地 SSD 磁盘上的所有数据。如需将数据保留在本地 SSD 磁盘上,您必须使用带有 --discard-local-ssd=false 标志的 gcloud CLI 停止虚拟机。如需了解详情,请参阅停止具有本地 SSD 的虚拟机

如需停止虚拟机,请选择本文档中介绍的方法之一:

停止虚拟机后,您可以重启虚拟机删除虚拟机。如果您不打算重启虚拟机,建议您将其删除。

通过 Google Cloud 停止虚拟机

如需一次停止多个虚拟机,请使用 Google Cloud 控制台。

控制台

如需停止一个或多个虚拟机,请执行以下操作:

  1. 在 Google Cloud 控制台中,转到虚拟机实例页面。

    转到虚拟机实例

  2. 选择要停止的虚拟机。

  3. 点击 停止,然后点击停止进行确认。

gcloud

如需停止虚拟机,请使用 gcloud compute instances stop 命令

gcloud compute instances stop VM_NAME \
    --project=PROJECT_ID \
    --zone=ZONE

替换以下内容:

  • VM_NAME:虚拟机的名称。

  • PROJECT_ID:虚拟机所在项目的 ID。

  • ZONE:该虚拟机所在的可用区。

如果您将本地 SSD 磁盘挂接到虚拟机,并希望在停止虚拟机后保留本地 SSD 数据,请使用带有 --discard-local-ssd=false 标志的 gcloud beta compute instances stop 命令

gcloud beta compute instances stop VM_NAME \
    --discard-local-ssd=false \
    --project=PROJECT_ID \
    --zone=ZONE

Go

	"context"

	}

	if err = op.Wait(ctx); err != nil {

REST

如需重启虚拟机,请向 instances.start 方法发出 POST 请求。

 POST https://www.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/instances/VM_NAME/start

替换以下内容:

  • VM_NAME:要重启的虚拟机的名称。

  • PROJECT_ID:虚拟机所在项目的 ID。

  • ZONE:该虚拟机所在的可用区。

重启使用加密磁盘的虚拟机

您可以重启已停止的虚拟机,该虚拟机使用客户提供的加密密钥来加密挂接到虚拟机的永久性磁盘。

控制台

如需重启使用加密磁盘的虚拟机,请执行以下操作:

  1. 在 Google Cloud 控制台中,转到虚拟机实例页面。

    转到虚拟机实例

  2. 选择要重启的虚拟机。

  3. 点击 启动/恢复

  4. 为挂接到此虚拟机的每个加密磁盘指定加密密钥,然后点击开始

gcloud

如需重启使用加密磁盘的虚拟机,请使用带有 --csek-key-file 标志的 gcloud compute instances start 命令。如果您使用的是 RSA 封装密钥,请改用 gcloud beta compute instances start 命令

gcloud compute instances start VM_NAME \
    --csek-key-file=ENCRYPTION_KEY_FILE \
    --project=PROJECT_ID \
    --zone=ZONE

替换以下内容:

  • VM_NAME:虚拟机的名称。

  • ENCRYPTION_KEY_FILE:包含客户提供的加密密钥的 JSON 文件的相对路径。

  • PROJECT_ID:虚拟机所在项目的 ID。

  • ZONE:该虚拟机所在的可用区。

  • ENCRYPTION_KEY:用于加密挂接到虚拟机的永久性磁盘的加密密钥。rawKeyrsaEncryptedKey 密钥必须采用 base64 编码。此外,如需准备 rsaEncryptedKey 密钥,请参阅 RSA 密钥封装

重置虚拟机

对正在运行的虚拟机执行重置类似于对计算机执行硬重启,例如按下重置按钮或按住电源按钮。重置虚拟机时,您没有给虚拟机留出时间来彻底关闭客机操作系统。因此,这可能会损坏磁盘的文件系统。Google Cloud 建议仅在客机操作系统崩溃且您没有其他选项时重置虚拟机。如果要重新初始化虚拟机并执行彻底关停,请参阅本文档中的重新启动虚拟机

重置虚拟机时,会发生以下情况:

  • 虚拟机会使用原始元数据、映像和永久性磁盘重新初始化为初始启动状态。

  • 除非您备份数据,否则虚拟机会强制擦除机器内存中的内容。

  • 在整个过程中,虚拟机将保持 RUNNING 状态。

虚拟机重置操作不会更改其任何虚拟机属性。虚拟机会保留其临时 IP 地址、静态外部 IP 地址、永久性磁盘、本地 SSD 磁盘(如果有)和机器类型。

控制台

如需重置一个或多个正在运行的虚拟机,请执行以下操作:

  1. 在 Google Cloud 控制台中,转到虚拟机实例页面。

    转到虚拟机实例

  2. 选择要重置的虚拟机。

  3. 点击重置,然后再次点击重置

gcloud

如需重置正在运行的虚拟机,请使用 gcloud compute instances reset 命令

gcloud compute instances reset VM_NAME \
    --project=PROJECT_ID \
    --zone=ZONE

替换以下内容:

  • VM_NAME:虚拟机的名称。

  • PROJECT_ID:虚拟机所在项目的 ID。

  • ZONE:该虚拟机所在的可用区。

REST

如需重置正在运行的虚拟机,请向 instances.reset 方法发出 POST 请求。

 POST https://www.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/instances/VM_NAME/reset

替换以下内容:

  • VM_NAME:虚拟机的名称。

  • PROJECT_ID:虚拟机所在项目的 ID。

  • ZONE:该虚拟机所在的可用区。

重新启动虚拟机

从客机操作系统内部重新启动虚拟机时,会发生以下情况:

  • 虚拟机会使用原始元数据、映像和永久性磁盘重新初始化为初始启动状态。

  • 除非您备份数据,否则虚拟机会擦除机器内存中的内容。

  • 在整个过程中,虚拟机将保持 RUNNING 状态。

与重置虚拟机相比,如果从客机操作系统中重新启动虚拟机,系统会等待虚拟机完成所有正在运行的任务,然后再将 ACPI 关停信号发送到虚拟机。这样,虚拟机便能够执行彻底关闭。

重新启动虚拟机时,不会更改其任何虚拟机属性。虚拟机会保留其临时 IP 地址、静态外部 IP 地址、永久性磁盘、本地 SSD 磁盘(如果有)和机器类型。

Linux

如需重置 Linux 虚拟机,请运行以下命令来重新启动客机操作系统:

sudo reboot

Windows

如需重置 Windows 虚拟机,请运行以下命令来重新启动客机操作系统:

shutdown /r /t 0

(可选)如需监控关停和重启虚拟机的过程,请启用 Windows 启动管理器菜单

结算

在虚拟机停止并且 Compute Engine 将其状态设置为 TERMINATED 后,您无需再支付 CPU 使用费。但是,挂接到虚拟机的所有资源(例如永久性磁盘外部 IP 地址)将会继续产生费用。

如需让挂接到虚拟机的资源停止产生费用,请执行以下操作之一:

  • 将这些资源与已停止的虚拟机分离。

  • 删除虚拟机。此操作也会删除关联到该虚拟机的所有资源。
