Windows CloudFormation 脚本、元数据命令未运行

Question

下面是我的 CloudFormation 模板，用于创建安装了 Java 和 Tomcat 的 Windows EC2 实例。然而，元数据中的任何内容都没有被执行。我登录创建的EC2实例，找不到元数据中指定的文件夹。我的 CloudFormation 脚本缺少什么？

谢谢

您需要检查两件事:

1. 检查这些脚本是否在位置 C:\cfn\scripts 上创建--如果没有则检查问题出在哪里

2. 如果这些脚本是在那里创建的，则单独调用 configSets 中的步骤 “commands”(第 33-34 行)。我怀疑这是实际脚本没有被调用的问题。
