我想通過雲形成來設置我的基礎架構。據我瞭解，有兩種安裝軟件包的方法。正確的安裝和調試方法使用AWS Cloud Formation安裝軟件包
選項1）
"packages": {
"apt-get": {
"epel-release": [],
"gcc-c++": [],
"make": [],
"git": []
}
}
選項2）隨着等待條件
"UserData": {
"Fn::Base64": {
"Fn::Join": [
"",
[
"#!/bin/bash -ex\n",
"apt-get update -y aws-cfn-bootstrap\n",
"apt-get install -y aws-cli\n",
...
現在我等待條件超時安裝包時。我讀到目前爲止，有三個選項：
調試1）發送一個錯誤，當安裝失敗
"npm install pm2 -g || error_exit 'Failed to install pm2.'\n",
調試2）成功步驟後發送積極的信號：
"/opt/aws/bin/cfn-signal -e 0 -r \"AWS installed node & npm.\" '",
調試3）檢出日誌 http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/troubleshooting.html
問題
問題1） 我沒有看到調試1中提到的任何失敗消息，我如何重寫模板，以確保這些消息在事件中正確顯示。
問題2） 也許是因爲它已經在第一步失敗了。但是，我可以看到/使其可見，哪些子步驟已通過？
問題3） 我在我的Mac &我的根帳戶運行aws configure安裝aws。我如何從那裏訪問日誌。由於EC2實例尚未運行，因此我不能只是ssh。

你確定你不能ssh到實例嗎？當CF堆棧創建失敗時，您是否因失敗而停用回滾，以便您的實例不會被銷燬？ –
我不知道這是可能的。我是否必須在LinuxEC2Instance之後添加'DisableRollback：false'：{'或開頭的右邊例如在'「Parameters」之後：{' –
它不在CloudFormation模板中。這是您創建堆棧時的一個選項。如果您使用AWS控制檯，它位於「高級」選項（第3個屏幕）上。如果您使用AWS CLI，則有一個選項：http://docs.aws.amazon.com/cli/latest/reference/cloudformation/create-stack.html –
