How to assign a public IP address to an instance in Linux

describe

When calling this interface, you need to pay attention to the following:

Before assigning a public IP address, the instance must be in the Running or Stopped state.

If an EIP is bound to a VPC instance, a public IP address cannot be assigned to it.

An instance can only be assigned one public IP address. If the instance already has a public IP address, an error message AllocatedAlready will be displayed.

After you restart the instance (RebootInstance) or start the instance (StartInstance), the new public IP address takes effect.

If the OperationLocks of a security-controlled instance is marked with "LockReason" : "security", a public IP address cannot be assigned.

In addition to assigning a public IP address, you can also bind an Elastic IP address (EIP) to an instance. For more details, see AssociateEipAddress.
