下列程式碼範例會示範如何使用reboot-cache-cluster

AWS CLI

重新啟動快取叢集

下列reboot-cache-cluster範例會重新啟動已佈建叢集內部分或全部快取節點。此作業會將任何修改過的快取參數群組套用至叢集。重新開機作業會盡快進行,並導致叢集暫時中斷。在重新開機期間,叢集狀態會設定為REBOOTING

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

輸出:

{ "CacheCluster": { "CacheClusterId": "my-cluster-001", "ClientDownloadLandingPage": "https://console.aws.amazon.com/elasticache/home#client-download:", "CacheNodeType": "cache.r5.xlarge", "Engine": "redis", "EngineVersion": "5.0.5", "CacheClusterStatus": "rebooting cache cluster nodes", "NumCacheNodes": 1, "PreferredAvailabilityZone": "us-west-2a", "CacheClusterCreateTime": "2019-11-26T03:35:04.546Z", "PreferredMaintenanceWindow": "mon:04:05-mon:05:05", "PendingModifiedValues": {}, "NotificationConfiguration": { "TopicArn": "arn:aws:sns:us-west-2:xxxxxxxxxx152:My_Topic", "TopicStatus": "active" }, "CacheSecurityGroups": [], "CacheParameterGroup": { "CacheParameterGroupName": "mygroup", "ParameterApplyStatus": "in-sync", "CacheNodeIdsToReboot": [] }, "CacheSubnetGroupName": "kxkxk", "AutoMinorVersionUpgrade": true, "SecurityGroups": [ { "SecurityGroupId": "sg-xxxxxxxxxxxxx836", "Status": "active" }, { "SecurityGroupId": "sg-xxxxxxxx7b", "Status": "active" } ], "ReplicationGroupId": "my-cluster", "SnapshotRetentionLimit": 0, "SnapshotWindow": "07:30-08:30", "TransitEncryptionEnabled": false, "AtRestEncryptionEnabled": false } }

下列程式碼範例會示範如何使用reset-cache-parameter-group

AWS CLI

重設快取參數群組

下列reset-cache-parameter-group範例會將快取參數群組的參數修改為引擎或系統預設值。您可以透過提交參數名稱清單來重設特定參數。若要重設整個快取參數群組,請指定--reset-all-parameters--cache-parameter-group-name參數。

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

輸出:

{ "CacheParameterGroupName": "mygroup" }

下列程式碼範例會示範如何使用start-migration

AWS CLI

若要開始移轉

以下步驟使用 Redis start-migration 引擎將您的資料從 Amazon EC2 上的自我託管 Redis 遷移到 Amazon ElastiCache。

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

輸出
