您好，这是我使用负载均衡器自动扩展的模板，我还附加了带有扩展/缩减策略的 cpu 警报，但是每当我要创建堆栈时，我都会收到一个错误，即无效的模板资源属性“WebServerScaleUpPolicy” .所以请让我知道我在这方面缺乏什么。
请帮帮我。 {AWS CloudFormation 模板 AutoScalingMultiAZ：创建在 nginx Web 服务器上运行的多可用区、负载平衡和自动扩展的示例网站。该应用程序配置为跨区域中的所有可用区，并根据 Web 服务器的 CPU 利用率自动扩展。
通过针对默认网页的简单运行状况检查对实例进行负载平衡。
【问题讨论】：
-
“创建一个多可用、负载平衡和自动缩放的示例......”这是一些家庭作业或工作分配的一部分吗？因此，您收到了一个损坏的模板并负责修复它？
-
因为我正在创建一个 cloudformation 模板，它基本上是工作的一部分。我在这个问题上面临这样的问题，因为我是 Cloud-formation 的新手。如果你能帮我解决这个问题，我真的很感激
-
如果您是 CloudFormation 新手，建议查看 CloudFormation Linter
-
投票结束，因为这只是一个语法错误。
