Web 界面有一个有用的选项“如果已连接，则允许重新关联弹性 IP”。如何使用云信息来做到这一点？ (或博托)？
最佳答案
无需为仅限 ec2-vpc 的帐户指定这一点。
[EC2-Classic, VPC in an EC2-VPC-only account] If the Elastic IP address is already associated with a different instance, it is disassociated from that instance and associated with the specified instance. If you associate an Elastic IP address with an instance that has an existing Elastic IP address, the existing address is disassociated from the instance, but remains allocated to your account.
