我已经使用 Ubuntu 16.04 编写了一个 cloudformation 脚本并实现了 userdata/cloud init 脚本。但是，当它尝试启动 cfn-hup 时，它会根据 init.d 脚本失败。脚本如下。我到处搜索以了解默认开始级别，我可以手动编辑它们，但我无法在任何其他模板中找到这是必要的，所以我一定是做错了什么？!脚本如下。
如果有人有想法请分享，非常感谢!

最佳答案
如果 Ubuntu 是您的目标部署，那么您似乎链接了错误的 cfn-hup 初始化脚本。如果您在符号链接(symbolic link)的 cfn-hup 文件中查找 LSB header ，您会注意到它们不存在。
它隐藏在 cfn-hup 文档中: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-helper-scripts-reference.html ，但对于 Ubuntu，您需要符号链接(symbolic link) AWS 提供的不同 init 脚本(而不是代码中的 /usr/local/bin/cfn-hup):
ln -s /root/aws-cfn-bootstrap-latest/init/ubuntu/cfn-hup /etc/init.d/cfn-hup
但是，该文件可能位于不同的位置，具体取决于您安装
aws-cfn-boostrap-latest.tar.gz 的方式，对我而言，它位于此处:/usr/local/lib/python2.7/dist-packages/aws_cfn_bootstrap-1.4-py2.7.egg/init/ubuntu/cfn-hup
您还需要运行:
update-rc.d cfn-hup defaults
就在开始
cfn-init 之前。关于amazon-web-services - AWS Cloudformation cfn-hup 在默认启动级别失败，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/48300896/
