我想通过云形成来设置我的基础架构。据我了解，有两种安装软件包的方法。正确的安装和调试方法使用AWS Cloud Formation安装软件包
选项1）
"packages": {
"apt-get": {
"epel-release": [],
"gcc-c++": [],
"make": [],
"git": []
}
}
选项2）随着等待条件
"UserData": {
"Fn::Base64": {
"Fn::Join": [
"",
[
"#!/bin/bash -ex\n",
"apt-get update -y aws-cfn-bootstrap\n",
"apt-get install -y aws-cli\n",
...
现在我等待条件超时安装包时。我读到目前为止，有三个选项：
调试1）发送一个错误，当安装失败
"npm install pm2 -g || error_exit 'Failed to install pm2.'\n",
调试2）成功步骤后发送积极的信号：
"/opt/aws/bin/cfn-signal -e 0 -r \"AWS installed node & npm.\" '",
调试3）检出日志 http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/troubleshooting.html
问题
问题1） 我没有看到调试1中提到的任何失败消息，我如何重写模板，以确保这些消息在事件中正确显示。
问题2） 也许是因为它已经在第一步失败了。但是，我可以看到/使其可见，哪些子步骤已通过？
问题3） 我在我的Mac &我的根帐户运行aws configure安装aws。我如何从那里访问日志。由于EC2实例尚未运行，因此我不能只是ssh。

你确定你不能ssh到实例吗？当CF堆栈创建失败时，您是否因失败而停用回滚，以便您的实例不会被销毁？ –
我不知道这是可能的。我是否必须在LinuxEC2Instance之后添加'DisableRollback：false'：{'或开头的右边例如在'“Parameters”之后：{' –
它不在CloudFormation模板中。这是您创建堆栈时的一个选项。如果您使用AWS控制台，它位于“高级”选项（第3个屏幕）上。如果您使用AWS CLI，则有一个选项：http://docs.aws.amazon.com/cli/latest/reference/cloudformation/create-stack.html –
