Memulai ulang atau mereset instance Compute Engine

Dokumen ini menjelaskan cara melakukan reboot atau mereset 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.

Memulai ulang atau mereset 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 tindakan berikut:

  • Mulai ulang instance. Jika OS tamu Anda lambat atau berhenti berfungsi, maka memulai ulang akan memberikan waktu yang cukup untuk menyelesaikan tugas yang sedang berjalan sebelum dimatikan.

  • Reset instance. Reset instance hanya jika OS tamu mengalami error atau tidak merespons, dan Anda tidak memiliki opsi lain. Mereset instance tidak memungkinkan OS tamu dimatikan dengan benar. Tindakan ini dapat menghapus data yang belum disimpan dan dapat merusak sistem file disk mana pun.

Sebelum memulai

Peran yang diperlukan

Untuk mendapatkan izin yang Anda perlukan untuk mereset atau mem-reboot instance komputasi, minta administrator untuk memberi Anda peran IAM Compute Instance Admin (v1) (roles/compute.instanceAdmin.v1) di 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 tamunya: compute.instances.setMetadata

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

Mulai ulang instance

Dengan melakukan rebooting instance komputasi, OS tamu di instance dapat menyelesaikan tugas yang sedang berjalan sebelum Compute Engine mengirimkan sinyal penonaktifan ACPI. Hal ini membantu memastikan penonaktifan bersih 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 me-reboot instance, pilih salah satu opsi berikut:

Linux

  1. Jika Anda belum melakukannya, hubungkan ke instance.

  2. Untuk me-reboot instance, jalankan perintah berikut:

    sudo reboot

Windows

  1. Jika Anda belum melakukannya, hubungkan ke instance menggunakan salah satu metode berikut:

  2. Untuk me-reboot instance, jalankan perintah berikut:

    shutdown /r /t 0

  3. Opsional: Untuk memantau proses mematikan dan memulai ulang instance, aktifkan menu Windows Boot Manager.

Mereset instance

Mereset instance akan menghapus semua data dalam memori instance, termasuk file sementara yang disimpan di disk RAM. Data ini akan hilang secara permanen dan Compute Engine tidak membuat cadangan sebelum mereset instance.

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

Konsol

  1. Di konsol Trusted Cloud , buka halaman VM instances.

    Buka instance VM

  2. Pilih instance yang akan direset.

  3. Klik Reset, lalu klik Reset untuk mengonfirmasi.

gcloud

Untuk mereset satu atau beberapa instance yang berjalan dalam 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 dengan spasi—misalnya, instance-01 instance-02 instance-03.

  • ZONE: zona tempat instance berada.

// resetInstance resets a running Google Compute Engine instance (with unencrypted disks).

	// projectID := "your_project_id"

	// 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.s3nsapis.fr//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.
