我正在尝试创建一个简单的Web部署模板，该模板引用另一个模板中的资源。实例创建成功但终止时出现信号故障错误。我是CloudFormation的新手，似乎在这里遇到了障碍 -
我能够启动Linux EC2实例，安装httpd并创建一个index.html，但代码无法执行它看起来的帮助程序脚本

我看到一些问题。
当前的问题是在AWS::CloudFormation::Init部分的拼写错误，你有Packages与大写P，而docs表明它应该是packages都是小写。这导致不安装httpd包，这反过来导致services部分尝试启动httpd时看到的错误消息。
这会导致UserData脚本错误输出，因此不会发送cfn-signal，并显示错误消息：
在指定的持续时间内无法接收1个资源信号
另外，（我的意思是你的模板的第二个版本），还有其他的拼写错误，其中mode，owner和group都被错误地缩进（一个级别太深）。这将导致所有配置被误解为文件内容的一部分。
如果你解决了这一切，那应该没问题。
首先，我应该提到模板已经过时了。它使用的是2016年的AMI，所有这些映射都可以用基于Query for the latest Amazon Linux AMI IDs using AWS Systems Manager Parameter Store | AWS Compute Blog的简单参数替换。
无论如何，您收到的错误表明在EC2实例上运行的启动脚本未能表示成功。
EC2实例上的/var/log/cloud-init-output.log文件说：
Error occurred during build: Could not enable service httpd (return code 1)
因此，这些配置行似乎有问题：
services:
sysvinit:
httpd:
enabled: 'true'
ensureRunning: 'true'
