我正在基于以下模板尝试Cloudformation CFN-INIT和CFN-HUP，但未创建wordpress堆栈。 CFN-HUP进程未启动，并且CFN-Init引发Code1错误。请参阅下面的堆栈模板和错误日志详细信息。谁能帮我了解这里出了什么问题？

最佳答案
看起来主要错误在cfn-hup.log中:
尝试将[main-just some name]中的[main]更改为cfn-hup.conf。供引用，我的/etc/cfn/cfn-hup.conf看起来像这样:
[main]
stack=arn:aws:cloudformation:us-west-1:acccount_id:stack/mystack-dev-ecs-EC2-1VF68LZMOLAIY/cb2a6a80-554a-11e8-b318-503dcab41efa
