【中文标题】AWS-CLI:在从快照创建的现有集群中创建 RDS Aurora 数据库实例【英文标题】:AWS-CLI : Create RDS Aurora DB instance into existing cluster created from snapshot 【发布时间】:2017-12-30 06:30:39 【问题描述】:根据我的研究,我发现使用 CLI 从现有快照创建包含实例的 Aurora 集群的唯一方法是按照以下步骤操作:
1) 从现有集群创建快照
2) 从快照启动集群
3) 将实例添加到集群中
因此,我使用最新的 AWS CLI 版本运行的命令如下(以及输出):
aws rds create-db-cluster-snapshot \
--db-cluster-snapshot-identifier analytics-replica-db \
--db-cluster-identifier prodcluster
哪个输出
"DBClusterSnapshot":
"Engine": "aurora",
"SnapshotCreateTime": "2017-07-24T15:08:12.836Z",
"VpcId": "vpc-ID",
"DBClusterIdentifier": "cluster_name",
"DBClusterSnapshotArn": "arn:aws:rds:eu-west-1:aws_account:cluster-snapshot:analytics-replica-db",
"MasterUsername": "db_username",
"LicenseModel": "aurora",
"Status": "creating",
"PercentProgress": 0,
"DBClusterSnapshotIdentifier": "analytics-replica-db",
"IAMDatabaseAuthenticationEnabled": false,
"ClusterCreateTime": "2016-04-14T11:10:02.413Z",
"StorageEncrypted": false,
"AllocatedStorage": 1,
"EngineVersion": "5.6.10a",
"SnapshotType": "manual",
"AvailabilityZones": [
"eu-west-1a",
"eu-west-1b",
"eu-west-1c"
],
"Port": 0
之后,我使用这个创建集群:
aws rds restore-db-cluster-from-snapshot \
--db-cluster-identifier analytics-replica-cluster \
--snapshot-identifier analytics-replica-db \
--engine aurora \
--port 3306 \
--db-subnet-group-name this_is_a_subnet_group \
--database-name this_is_the_database_name_equal_to_original_cluster_db \
--vpc-security-group-ids this_is_a_random_security_group \
--no-enable-iam-database-authentication
哪个输出
"DBCluster":
"MasterUsername": "this_is_the_same_username_as_the_one_on_original_db",
"ReaderEndpoint": "this_is_the_new_RDS_endpoint_of_cluster",
"ReadReplicaIdentifiers": [],
"VpcSecurityGroups": [
"Status": "active",
"VpcSecurityGroupId": "this_is_that_security_group"
],
"HostedZoneId": "Z29XKXDKYMONMX",
"Status": "creating",
"MultiAZ": false,
"PreferredBackupWindow": "23:50-00:20",
"DBSubnetGroup": "this_is_a_subnet_group",
"AllocatedStorage": 1,
"BackupRetentionPeriod": 10,
"PreferredMaintenanceWindow": "fri:03:34-fri:04:04",
"Engine": "aurora",
"Endpoint": "this_is_the_new_RDS_endpoint_of_reader",
"AssociatedRoles": [],
"IAMDatabaseAuthenticationEnabled": false,
"ClusterCreateTime": "2017-07-24T15:11:07.003Z",
"EngineVersion": "5.6.10a",
"DBClusterIdentifier": "analytics-replica-cluster",
"DbClusterResourceId": "cluster-resource_id",
"DBClusterMembers": [],
"DBClusterArn": "arn:aws:rds:eu-west-1:aws_account:cluster:analytics-replica-cluster",
"StorageEncrypted": false,
"DatabaseName": "this_is_the_database_name_equal_to_original_cluster_db",
"DBClusterParameterGroup": "default.aurora5.6",
"AvailabilityZones": [
"eu-west-1a",
"eu-west-1b",
"eu-west-1c"
],
"Port": 3306
现在,我只想运行这个
aws rds create-db-instance \
--db-name this_is_the_database_name_equal_to_original_cluster_db \
--db-instance-identifier analytics-replica-instance \
--db-instance-class "db.r3.large" \
--publicly-accessible \
--no-enable-iam-database-authentication \
--db-cluster-identifier analytics-replica-cluster \
--engine aurora
哪个输出
调用 CreateDBInstance 操作时发生错误 (InvalidParameterCombination):请求的数据库实例将成为数据库集群的成员。为数据库集群设置数据库名称。
有人能告诉我它为什么讨厌我吗?
【问题讨论】:
不要传递--db-name
,因为这是在集群上设置的,而不是在实例上。 “请求的数据库实例将是数据库集群的成员。[您只能]为数据库集群[而不是实例]设置[该]数据库名称。”
谢谢!稍后在集群上没有 --db-name
的情况下再试一次
你是对的!我对错误消息的理解很差。非常感谢您的帮助!!!
【参考方案1】:
对于面临相同问题的任何人,当您将新实例添加到极光集群时,某些选项不可用。
这个错误一开始很棘手,但很容易理解。最后一部分,Set database name for the DB Cluster.
表示真正的问题,并且大多数情况下,您需要删除该属性。
另一个例子An error occurred (InvalidParameterCombination) when calling the CreateDBInstance operation: The requested DB Instance will be a member of a DB Cluster. Set backup retention period for the DB Cluster.
你需要删除--backup-retention-period
