为什么我无法从我的 PC 连接到新的 AWS Aurora Serverless 实例？

Question

尝试设置一个普通的 AWS RDS Aurora Serverless 实例。

现在，我只想直接从我的 PC 连接到它作为健全性检查，但我无法这样做。每次我通过 连接时$ mysql，它都会等待几分钟。然后我得到：

$ mysql -h <MY-DATABASE>.cluster-deadbeef.us-west-1.rds.amazonaws.com -P 3306 -u admin -p
ERROR 2003 (HY000): Can't connect to MySQL server on '<MY-DATABASE>.cluster-deadbeef.us-west-1.rds.amazonaws.com' (60)

（nc也只是超时）

看起来我在某处建立了网络连接，但我不确定在哪里。

这是整个设置（认为我已经包含了所有相关内容？）：

• 数据库实例：

  $ aws rds describe-db-clusters --output json | jq '.DBClusters[0] | {AvailabilityZones, DBSubnetGroup, VpcSecurityGroups}'
  {
    "AvailabilityZones": [
      "us-west-1c",
      "us-west-1b"
    ],
    "DBSubnetGroup": "default-vpc-0165fd69fae5d2569",
    "VpcSecurityGroups": [
      {
        "VpcSecurityGroupId": "sg-051e6ad0fe8837a56",
        "Status": "active"
      }
    ]
  }
  

• 专有网络：

  $ aws ec2 describe-vpcs --output json | jq '.Vpcs[0] | {VpcId, CidrBlock, CidrBlockAssociationSet}'
  {
    "VpcId": "vpc-0165fd69fae5d2569",
    "CidrBlock": "10.0.0.0/16",
    "CidrBlockAssociationSet": [
      {
        "AssociationId": "vpc-cidr-assoc-0fe35851049a94f32",
        "CidrBlock": "10.0.0.0/16",
        "CidrBlockState": {
          "State": "associated"
        }
      }
    ]
  }
  

• VPC 子网：

  $ aws ec2 describe-subnets --output json | jq '.Subnets[] | {AvailabilityZone,AvailabilityZoneId,CidrBlock,VpcId}'  
  
  {
    "AvailabilityZone": "us-west-1c",
    "AvailabilityZoneId": "usw1-az1",
    "CidrBlock": "10.0.1.0/24",
    "VpcId": "vpc-0165fd69fae5d2569"
  }
  {
    "AvailabilityZone": "us-west-1b",
    "AvailabilityZoneId": "usw1-az3",
    "CidrBlock": "10.0.0.0/24",
    "VpcId": "vpc-0165fd69fae5d2569"
  }
  

• 安全组：

  是的，目前完全开放，仍然无法连接:(

  $ aws ec2 describe-security-groups --output json | jq '.SecurityGroups[]'
  {
    "IpPermissions": [
      {
        "IpProtocol": "-1",
        "IpRanges": [
          {
            "CidrIp": "0.0.0.0/0"
          }
        ],
        "Ipv6Ranges": [
          {
            "CidrIpv6": "::/0"
          }
        ],
        "PrefixListIds": [],
        "UserIdGroupPairs": [
          {
            "GroupId": "sg-051e6ad0fe8837a56",
          }
        ]
      },
      {
        "FromPort": 3306,
        "IpProtocol": "tcp",
        "IpRanges": [
          {

          }
        ],
        "Ipv6Ranges": [
          {
            "CidrIpv6": "::/0"
          }
        ],
        "PrefixListIds": [],
        "ToPort": 3306,
        "UserIdGroupPairs": []
      }
    ],
    "GroupId": "sg-051e6ad0fe8837a56",
    "IpPermissionsEgress": [

        ],
        "Ipv6Ranges": [],

        "UserIdGroupPairs": []
      }
    ],
    "VpcId": "vpc-0165fd69fae5d2569"
  }
  

• 路线表：

  $ aws ec2 describe-route-tables --output json | jq '.RouteTables[]'   
  {
    "Associations": [
      {
        "Main": true,
        "RouteTableAssociationId": "rtbassoc-0aebc4a882b0cd2a5",
        "RouteTableId": "rtb-0ce6ee26652736941",
        "AssociationState": {
          "State": "associated"
        }
      },
      {
        "Main": false,
        "RouteTableAssociationId": "rtbassoc-047d54469da606a50",
        "RouteTableId": "rtb-0ce6ee26652736941",
        "SubnetId": "subnet-0744475e288c0424c",
        "AssociationState": {
          "State": "associated"
        }
      },
      {
        "Main": false,
        "RouteTableAssociationId": "rtbassoc-08c5ea54642014c95",
        "RouteTableId": "rtb-0ce6ee26652736941",
        "SubnetId": "subnet-0b9c99ff38b860725",
        "AssociationState": {
          "State": "associated"
        }
      }
    ],
    "RouteTableId": "rtb-0ce6ee26652736941",
    "Routes": [
      {
        "DestinationCidrBlock": "10.0.0.0/16",
        "GatewayId": "local",
        "Origin": "CreateRouteTable",
        "State": "active"
      },
      {
        "DestinationCidrBlock": "0.0.0.0/0",
        "GatewayId": "igw-0f8ad7dfe1eaa0c67",
        "Origin": "CreateRoute",
        "State": "active"
      }
    ],
    "VpcId": "vpc-0165fd69fae5d2569",
  }
  

我错过了什么？

谢谢！！

现在，我只想直接从我的 PC连接到它

您无法从本地系统访问 serverless-DB，它只能在 AWS 网络内访问。

您可以通过 EC2 实例配置ssh-tunnel以访问无服务器数据库或使用在同一 VPC 中运行的 VPN。

由于 Aurora Serverless 数据库集群没有可公开访问的终端节点，因此您的 MyClusterName 只能从同一 VPC 中访问。
