So löschen Sie einen Cache-Cluster

Im folgenden Beispiel für delete-cache-cluster wird der angegebene, zuvor bereitgestellte Cluster gelöscht. Mit dem Befehl werden alle zugehörigen Cache-Knoten, Knotenendpunkte und der Cluster selbst gelöscht. Wenn Sie von diesem Vorgang eine erfolgreiche Antwort erhalten, beginnt Amazon ElastiCache sofort mit dem Löschen des Clusters. Sie können diesen Vorgang nicht abbrechen oder rückgängig machen.

Dieser Vorgang ist für Folgendes nicht gültig:

Redis (Cluster-Modus aktiviert)-Cluster; ein Cluster, der das zuletzt gelesene Replikat einer Replikationsgruppe ist; eine Knotengruppe (Shard), für die der Multi-AZ-Modus aktiviert ist; ein Cluster aus einer Redis (Cluster-Modus aktiviert)-Replikationsgruppe; ein Cluster, der sich nicht im verfügbaren Status befindet

aws elasticache delete-cache-cluster \

So löschen Sie eine Cache-Parametergruppe

Im folgenden Beispiel für delete-cache-parameter-group wird die angegebene Cache-Parametergruppe gelöscht. Cache-Parametergruppen, die Cache-Clustern zugeordnet sind, können nicht gelöscht werden.

aws elasticache delete-cache-parameter-group \

Mit diesem Befehl wird keine Ausgabe zurückgegeben.

Weitere Informationen finden Sie unter Löschen einer Parametergruppe im Benutzerhandbuch zu ElastiCache‭‭.

So löschen Sie eine Replikationsgruppe

Im folgenden Beispiel für delete-replication-group wird eine vorhandene Replikationsgruppe gelöscht. Standardmäßig löscht dieser Vorgang die gesamte Replikationsgruppe, einschließlich der primary/primaries und aller Read Replicas. Wenn die Replikationsgruppe nur über eine primäre Gruppe verfügt, können Sie optional nur die Read Replicas löschen und dabei die Primärreplikate beibehalten, indem Sie =true setzen. RetainPrimaryCluster

Wenn Sie von diesem Vorgang eine erfolgreiche Antwort erhalten, beginnt Amazon ElastiCache sofort mit dem Löschen der ausgewählten Ressourcen. Sie können diesen Vorgang nicht stornieren oder rückgängig machen. Gilt nur für Redis.

aws elasticache delete-replication-group \

Entweder wird die Anzahl der Replikate in einer Redis (Cluster-Modus deaktiviert)-Replikationsgruppe dynamisch erhöht oder die Anzahl der Replikationsknoten in einer oder mehreren Knotengruppen (Shards) einer Redis (Cluster-Modus aktiviert)-Replikationsgruppe. Dieser Vorgang wird ohne Cluster-Ausfallzeit ausgeführt.

So starten Sie einen Cache-Cluster neu

Im folgenden Beispiel für reboot-cache-cluster werden einige oder alle Cache-Knoten in einem bereitgestellten Cluster neu gestartet. Bei diesem Vorgang werden alle geänderten Cache-Parametergruppen auf den Cluster angewendet. Der Neustart findet so schnell wie möglich statt und führt zu einem kurzzeitigen Ausfall des Clusters. Während des Neustarts wird der Cluster-Status auf REBOOTING gesetzt.

aws elasticache reboot-cache-cluster \
    --cache-cluster-id "my-cluster-001" \
    --cache-node-ids-to-reboot "0001"

    }
}

So setzen Sie eine Cache-Parametergruppe zurück

Im folgenden Beispiel für reset-cache-parameter-group werden die Parameter einer Cache-Parametergruppe auf den Standardwert der Engine oder des Systems zurückgesetzt. Sie können bestimmte Parameter zurücksetzen, indem Sie eine Liste mit Parameternamen einreichen. Wenn Sie die gesamte Cache-Parametergruppe zurücksetzen möchten, geben Sie die Parameter --reset-all-parameters und --cache-parameter-group-name an.

aws elasticache reset-cache-parameter-group \
    --cache-parameter-group-name "mygroup" \
    --reset-all-parameters

Ausgabe:

{
    "CacheParameterGroupName": "mygroup"
}

So starten Sie eine Migration

Im Folgenden werden Ihre Daten mithilfe der Redis-Engine von selbst gehostetem Redis auf Amazon EC2 zu Amazon start-migration ElastiCache migriert.

aws elasticache start-migration \
   --replication-group-id test \
   --customer-node-endpoint-list "Address='test.g2xbih.ng.0001.usw2.cache.amazonaws.com',Port=6379"

So testen Sie das Failover einer Knotengruppe

Im folgenden Beispiel für test-failover wird das automatische Failover auf die angegebene Knotengruppe (in der Konsole als Shard bezeichnet) in einer Replikationsgruppe (in der Konsole als Cluster bezeichnet) getestet.

aws elasticache test-failover /
    --replication-group-id "mycluster" /
    --node-group-id "0001"

Ausgabe:
