Arresta o riavvia una VM

Questo documento spiega come arrestare, riavviare, reimpostare o riavviare manualmente un di una macchina virtuale (VM). Queste operazioni sono utili nei seguenti scenari:

  • Arresta una VM se non la utilizzi più o se vuoi modificarne una o più delle sue proprietà; Ad esempio, se vuoi rinominare la VM, modifica tipo di macchina, aggiungi o rimuovi i dischi collegati o modifica il numero di CPU minimo completamente gestita. Dopo aver arrestato la VM, riavviala per riprendere il carico di lavoro oppure se non ti serve più.

  • Reimposta una VM se, ad esempio, la VM non risponde o se l'ospite operativo di sistema (OS). Dopo aver reimpostato la VM, puoi riprendere carico di lavoro.

  • Riavvia una VM dal sistema operativo guest se, ad esempio, vuoi cancellare i dati della VM e reinizializzarla allo stato di avvio originale. Dopo il giorno riavviando una VM dal suo sistema operativo guest, puoi riprendere il carico di lavoro.

Prima di iniziare

Ruoli obbligatori

Per ottenere le autorizzazioni necessarie per arrestare e riavviare una VM, chiedi all'amministratore di concederti Ruolo IAM Amministratore istanze Compute (v1) (roles/compute.instanceAdmin.v1) nel progetto. Per saperne di più sulla concessione dei ruoli, consulta Gestire l'accesso a progetti, cartelle e organizzazioni.

Questo ruolo predefinito contiene le autorizzazioni necessarie per arrestare e riavviare una VM. Per vedere le autorizzazioni esatte obbligatorie, espandi la sezione Autorizzazioni obbligatorie:

Autorizzazioni obbligatorie

Per arrestare e riavviare una VM sono necessarie le seguenti autorizzazioni:

  • Per arrestare una VM: compute.instances.stop sulla VM
  • Per arrestare una VM dal sistema operativo guest: compute.instances.setMetadata sulla VM se utilizza chiavi SSH pubbliche a livello di istanza.
  • Per riavviare una VM: compute.instances.start sulla VM
  • Per riavviare una VM che utilizza le chiavi di crittografia: compute.instances.startWithEncryptionKey sulla VM
  • Per reimpostare una VM: compute.instances.reset sulla VM
  • Per riavviare una VM dal sistema operativo guest: compute.instances.setMetadata sulla VM

Potresti anche riuscire a ottenere queste autorizzazioni con ruoli personalizzati altri ruoli predefiniti.

Arresta una VM

Quando arresti una VM in esecuzione, si verifica quanto segue:

  1. Compute Engine invia Arresto dell'ACPI alla VM e attende un breve periodo di tempo affinché il sistema operativo guest esegua arrestato. Quindi, Compute Engine imposta lo stato della VM su STOPPING, quindi esegue la transizione a TERMINATED entro un minuto.

  2. La VM viene reimpostata allo stato di accensione e conserva gli IP interni, il MAC indirizzi, impostazioni di configurazione e metadati. Tuttavia, la VM perde dei dati in memoria e dello stato delle VM. Se devi conservare i dati in memoria e la VM stato, sospendi la VM .

Inoltre, se hai collegato risorse alla VM, queste rimangono fino a quando non li scolleghi manualmente o non elimini la VM. Se la VM ha uno o più Dischi SSD locali collegati, l'arresto della VM comporta l'eliminazione di tutti i dati sull'SSD locale i dischi permanenti per impostazione predefinita. Per conservare i dati sui dischi SSD locali, devi arrestare la VM utilizzando gcloud CLI con il flag --discard-local-ssd=false. Per ulteriori informazioni, vedi Arresta una VM con SSD locale.

Per arrestare una VM, seleziona uno dei metodi descritti in questo documento:

Dopo aver arrestato una VM, puoi riavviarla oppure eliminala. Se non prevedi di farlo riavvia la VM ed è consigliabile eliminarla.

Arresta una VM tramite Google Cloud

Per arrestare più di una VM alla volta, utilizza la console Google Cloud.

Console

Per arrestare una o più VM:

  1. Nella console Google Cloud, vai alla pagina Istanze VM.

    Vai a Istanze VM

  2. Seleziona le VM da arrestare.

  3. Fai clic su Interrompi, quindi fai clic su Interrompi per confermare.

gcloud

Per arrestare una VM, utilizza Comando gcloud compute instances stop.

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

Sostituisci quanto segue:

  • VM_NAME: il nome della VM.

  • PROJECT_ID: l'ID del progetto in cui si trova la VM individuarlo.

  • ZONE: la zona in cui si trova la VM.

Se hai collegato un disco SSD locale alla VM e vuoi mantenere lo stato SSD dopo aver arrestato la VM, usa Comando gcloud beta compute instances stop con il flag --discard-local-ssd=false.

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

Reimposta una VM

La reimpostazione di una VM in esecuzione è un processo simile a un riavvio forzato sul computer, ad esempio come quando premi un tasto di ripristino o tieni premuto il tasto di accensione. Quando una VM, non concedi alla VM il tempo di eseguire un arresto anomalo il sistema operativo guest. Di conseguenza, ciò potrebbe danneggiare i file system del disco. Google Cloud consiglia di reimpostare una VM solo se si è verificato un arresto anomalo del sistema operativo guest e non hai altre opzioni. Se vuoi reinizializzare una VM ed eseguire una completamente, consulta Riavviare una VM in questo documento.

Quando reimposti una VM, si verifica quanto segue:

  • La VM si reinizializza allo stato di avvio iniziale con i metadati originali, dell'immagine e dischi permanenti.

  • La VM cancella forzatamente i contenuti della memoria della macchina a meno che tu non eseguire il backup dei dati.

  • Lo stato della VM rimane RUNNING per tutto il processo.

La reimpostazione di una VM non ne modifica nessuno Proprietà VM. La VM conserva i suoi IP temporanei, gli IP esterni statici, i dischi permanenti, Dischi SSD (se presenti) e tipo di macchina.

Console

Per reimpostare una o più VM in esecuzione:

  1. Nella console Google Cloud, vai alla pagina Istanze VM.

    Vai a Istanze VM

  2. Seleziona le VM da reimpostare.

  3. Fai clic su Reimposta, quindi di nuovo su Reimposta.

gcloud

Per reimpostare una VM in esecuzione, utilizza Comando gcloud compute instances reset.

gcloud compute instances reset VM_NAME \

REST

Per reimpostare una VM in esecuzione, effettua una richiesta POST alla Metodo instances.reset.

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

Sostituisci quanto segue:

  • VM_NAME: il nome della VM.

  • PROJECT_ID: l'ID del progetto in cui si trova la VM individuarlo.

  • ZONE: la zona in cui si trova la VM.

Riavvia una VM

Quando riavvii una VM dal sistema operativo guest, si verifica quanto segue:

  • La VM si reinizializza allo stato di avvio iniziale con i metadati originali, dell'immagine e dischi permanenti.

  • La VM cancella i contenuti della memoria della macchina a meno che tu eseguire il backup dei dati.

  • Lo stato della VM rimane RUNNING per tutto il processo.

Rispetto alla reimpostazione di una VM, il riavvio di una VM dall'interno del sistema operativo guest attende VM per completare tutte le attività in esecuzione prima di inviare l'arresto di ACPI alla VM. Ciò consente alla VM di eseguire un arresto pulito.

Il riavvio di una VM non ne modifica nessuno Proprietà VM. La VM conserva i suoi IP temporanei, gli IP esterni statici, i dischi permanenti, Dischi SSD (se presenti) e tipo di macchina.

Linux

Per reimpostare una VM Linux, riavvia il sistema operativo guest eseguendo questo comando:

sudo reboot

Windows

Per reimpostare una VM Windows, riavvia il sistema operativo guest eseguendo questo comando:

shutdown /r /t 0

Facoltativamente, per monitorare il processo di arresto e riavvio della VM, Attivare il menu Gestione di avvio di Windows.

Fatturazione

Dopo che una VM viene arrestata e Compute Engine imposta lo stato su TERMINATED, non ti vengono più addebitati costi per l'utilizzo della CPU. Tuttavia, continui a ricevere i costi per qualsiasi risorsa collegata alla VM, come dischi permanenti e indirizzi IP esterni.

Per interrompere l'addebito di costi per le risorse collegate a una VM, esegui una delle seguenti:

  • Scollega queste risorse dalla VM arrestata.

  • Elimina la VM. Questa azione elimina anche le risorse collegate alla VM.
