我发动我的PHP code Ubuntu的EC2实例和传递用户数据给它。 我不拥有该实例..但他们提供给它的用户级访问。

首先，我试图通过传递用户数据来运行特定的工作，但它似乎并没有工作。

我说的很简单，发送触摸的test.txt作为用户数据。实例被正确启动，但该文件没有被创建为应该是我猜。

我缺少任何一个步骤？我查了一下，这不是使用ssh荷兰国际集团，以实例创建的文件。有一件事是我是不是在实例根用户。请问是什么效果？

 ＆LT; PHP
使用error_reporting（-1）;
标题（内容类型：text / plain的;字符集= UTF-8）;
require_once'../sdk.class.php;
//实例化类
$ EC2 =新AmazonEC2（）;
$ userdata2 =摸喜，TXT;
回声$ userdata2;
$响应= $ ec2-＆GT; run_instances（'AMI-5f21e236'，1，1，
阵列（'KeyName是'=＆GT;基数2），
阵列（'的UserData'=＆GT; $ userdata2）
阵列（'InstanceType'=＆GT;'的m1.small）
）;
的var_dump（$响应 - ＆GT; isOK（））;
？＆GT;
 

解决方案

如果你想运行code为用户数据的脚本，那么你需要用两个字符开始用户数据＃！

例如，您的触摸命令可能是：

 ＃！/斌/庆典
触摸/tmp/hello-world.txt
 

我不是一个PHP程序员，但我认为这可能工作的基础上我的研究：

 ＃！的/ usr / bin中/ PHP
＆LT; PHP
[...您的code在这里...]
？＆GT;
 

下面就是我介绍了用户数据的脚本的概念文章：

这已被纳入其中所使用的一些AMI的发行版，包括Ubuntu和Linux的亚马逊Ubuntu的云的init包。

云初始化有一些更灵活的指定的东西在启动的方式，但shabang（＃！）方法是一种简单的方法，在第一次启动运行任何脚本。

I am launching a ubuntu EC2 instance with my PHP code and passing user data to it. I don't own that instance.. but they provide user level access to it.

Firstly i tried to run a particular job by passing user data, but it did not seem to work.

I made it very simple and send "touch test.txt" as user data. The instance was launched properly but the file was not created as should be i guess.

Am I missing any step? I checked that file was not created using ssh 'ing to the instance. One thing was i was not in root user at instance. Will that effect anything?

<?php
error_reporting(-1);
header("Content-type: text/plain; charset=utf-8");
require_once '../sdk.class.php';
// Instantiate the class
$ec2 = new AmazonEC2();
$userdata2="touch hi".".txt";
echo $userdata2;
$response = $ec2->run_instances('ami-5f21e236', 1, 1,
array('KeyName' => 'radix2'),
array('UserData' => $userdata2),
array('InstanceType' => 'm1.small')
);
var_dump($response->isOK());
?>

If you are trying to run your code as a user-data script, then you need to start the user data with the two characters #!

For example, your touch command might be:

#!/bin/bash
touch /tmp/hello-world.txt

I'm not a PHP programmer, but I think this might work based on my research:

#!/usr/bin/php
<?php
[...your code here...]
?>

Here's the article where I introduced the concept of user-data scripts:

This has been incorporated into Ubuntu's cloud-init package which is used by a number of AMI distros including Ubuntu and Amazon Linux.

cloud-init has some more flexible ways of specifying things at startup, but the shabang (#!) method is a simple way to run any script at first boot.
