但是回想了一下这台我基本没用过，只安装了nginx和php，出现漏洞的可能性极低。
看了下面这两个帖子，才发现lightsail极不稳定，即便是空跑的机器也极有可能会CPU100%

[ol]Now yesterday I was checking the instances again and of course one of ours was affected like usual. But what I also saw: A second lightsail instance was affected too and what was crazy is, that this instance is empty. Its a newly created ubuntu instance that did not have any running code (only a few files of a not running application in the ubuntu folder). How on earth would the 100% problem appear on a basically empty lightsail instance that has no user application running?
昨天我再次检查了实例，当然，我们的一个实例像往常一样受到影响。但我还看到：第二个 lightsail 实例也受到影响，疯狂的是，这个实例是空的。它是一个新创建的 ubuntu 实例，没有任何正在运行的代码（ubuntu 文件夹中只有几个未运行的应用程序的文件）。100% 问题究竟如何出现在一个基本上为空且没有运行用户应用程序的 lightsail 实例上？[/ol]复制代码
