Mereset atau memulai ulang instance Compute Engine

Linux Windows

Dokumen ini menjelaskan cara mereset atau memulai ulang instance Compute Engine. Untuk mempelajari lebih lanjut efek mereset instance, serta perbedaan antara menangguhkan, menghentikan, atau mereset instance, lihat Menangguhkan, menghentikan, atau mereset instance Compute Engine.

Mereset atau memulai ulang instance dapat membantu memastikan performa dan stabilitas yang optimal, atau membantu menyelesaikan masalah seperti sistem operasi (OS) tamu yang berhenti berfungsi, lambat, atau error. Berdasarkan status OS tamu instance Anda, lakukan salah satu hal berikut:

Mulai ulang instance. Jika OS tamu Anda lambat atau berhenti berfungsi, memulai ulang akan memberinya cukup waktu untuk menyelesaikan tugas yang sedang berjalan sebelum dimatikan.
Reset instance. Reset instance hanya jika OS tamu mengalami error, dan Anda tidak memiliki opsi lain. Mereset instance tidak memungkinkan penonaktifan bersih, sehingga dapat merusak sistem file disk booting atau non- booting.

Sebelum memulai

Jika Anda belum melakukannya, siapkan autentikasi. Autentikasi adalah proses verifikasi identitas Anda untuk mengakses layanan dan API Google Cloud. Untuk menjalankan kode atau contoh dari lingkungan pengembangan lokal, Anda dapat mengautentikasi ke Compute Engine dengan memilih salah satu opsi berikut:

Select the tab for how you plan to use the samples on this page:
Console

When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.
gcloud
1. Install the Google Cloud CLI, then initialize it by running the following command:
  gcloud init
  Note: If you installed the gcloud CLI previously, make sure you have the latest version by running gcloud components update.
2. Set a default region and zone.

Peran yang diperlukan

Untuk mendapatkan izin yang diperlukan guna mereset atau memulai ulang instance komputasi, minta administrator untuk memberi Anda peran IAM Compute Instance Admin (v1) (roles/compute.instanceAdmin.v1) pada instance. Untuk mengetahui informasi selengkapnya tentang cara memberikan peran, lihat Mengelola akses ke project, folder, dan organisasi.

Peran bawaan ini berisi izin yang diperlukan untuk mereset atau memulai ulang instance komputasi. Untuk melihat izin yang benar-benar diperlukan, luaskan bagian Izin yang diperlukan:

Izin yang diperlukan

Izin berikut diperlukan untuk mereset atau memulai ulang instance komputasi:

Untuk mereset instance: compute.instances.reset
Untuk memulai ulang instance dari dalam OS tamu: compute.instances.setMetadata

Anda mungkin juga bisa mendapatkan izin ini dengan peran khusus atau peran bawaan lainnya.

Memulai ulang instance

Memulai ulang instance komputasi memungkinkan OS tamu di instance menyelesaikan tugas yang sedang berjalan sebelum Compute Engine mengirimkan sinyal penonaktifan ACPI. Hal ini membantu memastikan penonaktifan bersih dari OS tamu.

Memulai ulang instance akan menghapus memori yang digunakan oleh instance. Jika Anda menggunakan disk RAM dengan instance, dan Anda perlu mempertahankan data tersebut, maka cadangkan data sebelum memulai ulang instance.

Untuk memulai ulang instance, pilih salah satu opsi berikut:

Linux

Jika Anda belum melakukannya, hubungkan ke instance.
Untuk memulai ulang instance, jalankan perintah berikut:
```
sudo reboot
```

Windows

Jika Anda belum melakukannya, hubungkan ke instance menggunakan salah satu metode berikut:
Untuk memulai ulang instance, jalankan perintah berikut:
```
shutdown /r /t 0
```
Opsional: Untuk memantau proses penonaktifan dan memulai ulang instance, aktifkan menu Windows Boot Manager.

Mereset instance

Mereset instance komputasi yang sedang berjalan akan menghapus memori yang digunakan oleh instance. Jika Anda menggunakan disk RAM dan perlu mempertahankan data ini, maka cadangkan data sebelum mereset instance.

Anda dapat mereset beberapa instance secara bersamaan atau satu per satu. Untuk beberapa instance, gunakan konsol Google Cloud atau, untuk instance yang berada di zona yang sama, Google Cloud CLI. Untuk setiap instance, pilih salah satu opsi berikut:

Konsol

Di konsol Google Cloud, buka halaman Instance VM.

Buka instance VM
Pilih instance yang akan direset.
Klik Reset, lalu klik Reset untuk mengonfirmasi.

gcloud

Untuk mereset satu atau beberapa instance yang berjalan di satu zona, gunakan perintah gcloud compute instances reset:

gcloud compute instances reset INSTANCE_NAMES \
    --zone=ZONE

Ganti kode berikut:

INSTANCE_NAMES: daftar nama instance yang dipisahkan spasi—misalnya, instance-01 instance-02 instance-03.
ZONE: zona tempat instance berada.

Go

import (
	"context"
	"fmt"
	"io"

	compute "cloud.google.com/go/compute/apiv1"
	computepb "cloud.google.com/go/compute/apiv1/computepb"
)

// resetInstance resets a running Google Compute Engine instance (with unencrypted disks).
func resetInstance(w io.Writer, projectID, zone, instanceName string) error {
	// projectID := "your_project_id"
	// zone := "europe-central2-b"
	// instanceName := "your_instance_name"

	ctx := context.Background()
	instancesClient, err := compute.NewInstancesRESTClient(ctx)
	if err != nil {
		return fmt.Errorf("NewInstancesRESTClient: %w", err)
	}
	defer instancesClient.Close()

	req := &computepb.ResetInstanceRequest{
		Project:  projectID,
		Zone:     zone,
		Instance: instanceName,
	}

	op, err := instancesClient.Reset(ctx, req)
	if err != nil {
		return fmt.Errorf("unable to reset instance: %w", err)
	}

	if err = op.Wait(ctx); err != nil {
		return fmt.Errorf("unable to wait for the operation: %w", err)
	}

	fmt.Fprintf(w, "Instance reset\n")

	return nil
}

REST

Untuk mereset instance yang sedang berjalan, buat permintaan POST ke metode instances.reset:

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

Ganti kode berikut:

INSTANCE_NAME: nama instance.
PROJECT_ID: ID project tempat instance berada.
ZONE: zona tempat instance berada.
