Question

我正在执行以下代码来创建堆栈。实例已创建，但收到此错误：

Loaded plugins: amazon-id, rhui-lb, search-disabled-repos
No Match for argument: aws-cfn-bootstrap
No package aws-cfn-bootstrap available.
No packages marked for update
/var/lib/cloud/instance/scripts/part-001: line 4: cd: /opt/aws/bin/cfn-init: No such file or directory

我的CloudFormation模板是：

看来Redhat没有预加载cfn-init。

您可以改用 Amazon Linux AMI ，也可以查看How to install aws-cfn-bootstrap/cfn-init package in Redhat using CloudFormation? - Stack Overflow，以获取有关如何在引导过程中加载cfn-init的提示。
