每天进步一点点：AWS 上删除实例 & Termination Protection

因为计划调整，需要停止AWS上的一个EC2实例，当然了，其实不关也没有什么毛病，就是会一直哗哗哗地扣费下去，只要你足够有钱，可以任性下去的。我没有钱，没法任性。

# 无法删除实例

按着步骤去删除实例：

>![image.png](https://images.hive.blog/DQmd1CGyDxctuTfZSUuXEigDSRDbu4qHfLeGBQKs9VRHYtr/image.png)


结果却被提示，不让删除，让关闭“disableApiTermination”属性后再试，这是什么鬼？
>![image.png](https://images.hive.blog/DQmZiKD75fKzAWo3gFhvxQTVeEdo3KkYjNgmTAKKCKpXXXY/image.png)

看了一眼实例的属性，有如下“Termination protection”信息：

# 关闭 Termination Protection

那么估计只要把实例的这个属性关闭掉，就应该可以删除实例啦。

先找到实例设置：

改变“Termination protection”
>![image.png](https://images.hive.blog/DQmTZXMTCu6KdLqEbE5SHNjAVr82RpgsxcVuu33p8dMxf1x/image.png)

之前的状态是“Enable”
>![image.png](https://images.hive.blog/DQme1JMnjK5ZLpuvX9xaMhBbSMpgXTdDAPPqKogTw2n4NMn/image.png)

我们把它取消掉：
>![image.png](https://images.hive.blog/DQmbaypKEjJiED3cs83heva9uWs9MW6p61RNaLSUuMkdtqD/image.png)

面板里会提示我们取消成功：
>![image.png](https://images.hive.blog/DQmXowWdU52LRv6mAFUr5mrjzgS4LwpeDkRmqLwQzzWFjL9/image.png)

再来确认一下状态：
>![image.png](https://images.hive.blog/DQmYJ39Ljq7iwoLcAn1eXWbjdJosZRTK1CpaX37LuQrsZwN/image.png)

再去终止实例，一切正常：

# 总结

因为实例设置了“Termination Protection”，所以删除的时候会无法直接删除掉的，需要额外去解除保护，然后再去删除，这个功能可以防止不小心误删除实例。

我当初创建实例的时候不小心设置了这个属性（其它实例我都没设置），所以触发删除保护倒是第一次呢。成功地删除了实例，我就放心了，这样就不会一直哗哗哗扣钱了。
