aws-cloudformation - 堆栈创建失败 - 在指定持续时间内无法接收 1 个资源信号

Question

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。实例已成功创建，但因信号失败错误而终止。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，但代码似乎无法执行帮助程序脚本

Answer 1

我发现了一些问题。

眼前的问题是 AWS::CloudFormation::Init 部分中的拼写错误，其中 Packages 的大小写为 P，而 docs指示它应该是 packages 全部小写。这会导致 httpd 软件包无法安装，进而导致您在 services 部分尝试启动 httpd 时看到错误消息。

这会导致 UserData 脚本出错，因此不会发送 cfn-signal，并且会看到错误消息:

Failed to receive 1 resource signal(s) within the specified duration

此外，(我的意思是在模板的第二个版本中)，还有其他拼写错误，其中 mode、owner 和 group 全部缩进不正确(一层太深)。这将导致所有配置被误解为文件内容的一部分。

如果你解决了所有问题，应该没问题。
