amazon-ec2 - ec2 centos 用户数据未运行

Question

我正在尝试在实例启动时使用用户数据通过centos ec2实例部署ruby on Rails应用程序，指定图像是centos 7图像。下面是我的用户数据部分。但是，当我将每个命令输出通过管道传输到日志时，用户数据不起作用，甚至没有创建日志文件。有谁对此有任何见解或如何解决 ec2 用户数据问题吗？我也查看了/var/logs 中的 cloud-init.log 文件，但无法确定哪个命令实际运行，哪个命令没有运行，我也包含了下面日志中的最后几行。感谢任何帮助，谢谢!

云形成？您是否记得对用户数据进行 Base64 编码？

  EventCollectionLc:
    Type: 'AWS::AutoScaling::LaunchConfiguration'
    Properties:
      UserData: !Base64 
        'Fn::Sub': |
