哥们多谢了。
我吐的是。。这个ELASTIC IP绑定,在关机开机后,会丢失的,你搜搜 :) ...
这里有个解释(http://www.ibm.com/developerwork ... brary/ar-cloudaws3/)
Elastic IP addresses
Each instance is automatically assigned a private and a public IP address on launch by EC2. The public IP address can, of course, be used to access the instance over the Internet. Each time you launch an instance, though, this address will change. If you are using any kind of dynamic DNS mapping for connecting a DNS name to the IP address, it can take as long as 24 hours before the change is propagated across the Internet.EC2 introduced the concept of an elastic IP address to alleviate this problem. Each elastic IP address is a static IP address that is associated with your EC2 account, not to a specific instance, and is permanently associated with your account unless you explicitly release it back to EC2.
You can also remap an elastic IP address among instances, and thus quickly respond to any instance failures by just starting another instance and remapping it (or using an existing instance). At any given time, you can only have a single instance mapped to an elastic IP address. |
