Question

正在尝试使用Cloud Formation Stack创建CodeDeploy部署组。每次我运行堆栈时，都会遇到脚本错误，例如错误的解释器，找不到rm / ll命令，/ r / n错误。我尝试使用dos2unix更改Shell脚本文件并压缩这些文件并上传到CodeDeploy，但没有成功。

以下是我在日志中得到的错误声明：

失败的可能原因是什么？

Answer 1

日志表明您的脚本存在一些问题，特别是BeforeInstall.sh。该脚本中的某个操作失败，退出代码为127。我建议向该脚本中添加日志，以查看实际失败的地方。识别出失败的命令后，就可以看到退出代码127对于该特定命令的含义。

如果您想帮助调试该特定脚本，则应该打开另一个问题并提供脚本，包括运行脚本时的日志。

CodeDeploy生命周期挂钩的说明

在您的情况下，您的BeforeInstall脚本失败了，该脚本将随您的应用程序一起部署。但是，如果您的ApplicationStop脚本失败了，那么一定要了解ApplicationStop使用的是上次成功部署的脚本，因此，如果上一次成功的部署有错误脚本，则可能导致将来的部署直到these steps are followed才失败。
