(AWS CLI) 查看群集的详细信息

您可以使用 AWS CLI describe-cache-clusters 命令查看群集的详细信息。如果省略 --cache-cluster-id 参数,则会返回多个群集(最多 --max-items 个)的详细信息。如果包含 --cache-cluster-id 参数,则将返回指定的群集的详细信息。您可以使用 --max-items 参数限制返回的记录数。

以下代码列出了 myCluster 的详细信息。

aws elasticache describe-cache-clusters --cache-cluster-id myCluster

以下代码列出了最多 25 个群集的详细信息。

aws elasticache describe-cache-clusters --max-items 25

使用命令 describe-cache-cluster 显示群集的节点列表,如以下示例所示,然后记下要移除的节点的标识符。

对于 Linux, OS X, or Unix:

aws elasticache describe-cache-clusters \ --cache-cluster-id my-memcached-cluster \ --show-cache-node-info

对于 Windows:

aws elasticache describe-cache-clusters ^ --cache-cluster-id my-memcached-cluster ^ --show-cache-node-info

此操作生成类似于下述信息的输出 (JSON 格式):

{ "CacheClusters": [ { "Engine": "memcached", "CacheNodes": [ { "CacheNodeId": "0001", "Endpoint": { "Port": 11211, "Address": "my-memcached-cluster.7ef-example.0001.usw2.cache.amazonaws.com" }, "CacheNodeStatus": "available", "ParameterGroupStatus": "in-sync", "CacheNodeCreateTime": "2016-09-21T16:28:28.973Z", "CustomerAvailabilityZone": "us-west-2b" }, { "CacheNodeId": "0002", "Endpoint": { "Port": 11211, "Address": "my-memcached-cluster.7ef-example.0002.usw2.cache.amazonaws.com" }, "CacheNodeStatus": "available", "ParameterGroupStatus": "in-sync", "CacheNodeCreateTime": "2016-09-21T16:28:28.973Z", "CustomerAvailabilityZone": "us-west-2b" }, { "CacheNodeId": "0003", "Endpoint": { "Port": 11211, "Address": "my-memcached-cluster.7ef-example.0003.usw2.cache.amazonaws.com" }, "CacheNodeStatus": "available", "ParameterGroupStatus": "in-sync", "CacheNodeCreateTime": "2016-09-21T16:28:28.973Z", "CustomerAvailabilityZone": "us-west-2b" } ], "CacheParameterGroup": { "CacheNodeIdsToReboot": [], "CacheParameterGroupName": "default.memcached1.4", "ParameterApplyStatus": "in-sync" }, "CacheClusterId": "my-memcached-cluster", "PreferredAvailabilityZone": "us-west-2b", "ConfigurationEndpoint": { "Port": 11211, "Address": "my-memcached-cluster.7ef-example.cfg.usw2.cache.amazonaws.com" }, "CacheSecurityGroups": [], "CacheClusterCreateTime": "2016-09-21T16:28:28.973Z", "AutoMinorVersionUpgrade": true, "CacheClusterStatus": "available", "NumCacheNodes": 3, "ClientDownloadLandingPage": "https://console.aws.amazon.com/elasticache/home#client-download:", "SecurityGroups": [ { "Status": "active", "SecurityGroupId": "sg-dbe93fa2" } ], "CacheSubnetGroupName": "default", "EngineVersion": "1.4.24", "PendingModifiedValues": {}, "PreferredMaintenanceWindow": "sat:09:00-sat:10:00", "CacheNodeType": "cache.m3.medium" } ] }
