Automount EBS volume in Amazon EC2 Windows Instance
提问by defeated
Does anyone know how to auto-mount an Elastic Block Storage(EBS) volume when starting a Windows 2003 instance in Amazon's Elastic Compute Cloud(EC2)?
有谁知道在 Amazon 的Elastic Compute Cloud(EC2) 中启动 Windows 2003 实例时如何自动挂载Elastic Block Storage(EBS) 卷？

Setup:
设置：
- Make sure the EBS volume is formatted and labeled (in the example I used the label PDRIVE).
- Setup a drive mapping using Ec2ConfigServiceSettings.exe
- Install Java on the instance
- Install the EC2 API command line tools
- Install a copy of your cert and private key
- Install a copy of curl.exe (open source tool)
- 确保 EBS 卷已格式化并标记（在示例中我使用了标签 PDRIVE）。
- 使用 Ec2ConfigServiceSettings.exe 设置驱动器映射
- 在实例上安装 Java
- 安装 EC2 API 命令行工具
- 安装您的证书和私钥的副本
- 安装 curl.exe 的副本（开源工具）

I found the following Ruby code at http://www.ioncannon.net/system-administration/199/automounting-amazon-ebs-volumes-on-ec2-instances/courtesy of Carson McDonald. It's for Linux/Unix but maybe you can re-swizzle this for Ruby on Windows 2003 or have it serve as a model for doing it in some other scripting language.
我在http://www.ioncannon.net/system-administration/199/automounting-amazon-ebs-volumes-on-ec2-instances/ 上找到了以下 Ruby 代码，由 Carson McDonald 提供。它适用于 Linux/Unix，但也许您可以在 Windows 2003 上为 Ruby 重新调整它，或者将其作为使用其他脚本语言执行此操作的模型。
Note that you could pass things into your image as user data such as the ECS EBS volume ID and the device name (e.g., /dev/sdh in the following example or whatever it would be in Windows for your case). You can access the user data from the instance itself as meta-data as is roughly done below to get the instance-id. More specifically, you'd access http://169.254.169.254/1.0/user-datato get to the user-data.
请注意，您可以将内容作为用户数据传递到您的映像中，例如 ECS EBS 卷 ID 和设备名称（例如，以下示例中的 /dev/sdh 或 Windows 中适用于您的情况的任何内容）。您可以从实例本身访问用户数据作为元数据，如下面粗略地完成以获取实例 ID。更具体地说，您将访问http://169.254.169.254/1.0/user-data以获取用户数据。
#!/usr/bin/ruby
require 'rubygems'
require 'right_aws'
require 'net/http'
url = 'http://169.254.169.254/2008-02-01/meta-data/instance-id'
instance_id = Net::HTTP.get_response(URI.parse(url)).body
AMAZON_PUBLIC_KEY='your public key'
AMAZON_PRIVATE_KEY='your private key'
EC2_LOG_VOL='the volume id'
ec2 = RightAws::Ec2.new(AMAZON_PUBLIC_KEY, AMAZON_PRIVATE_KEY)
vol = ec2.attach_volume(EC2_LOG_VOL, instance_id, '/dev/sdh')
puts vol
# It can take a few seconds for the volume to become ready.
# This is just to make sure it is ready before mounting it.
sleep 20
system('mount /dev/sdh /mymountpoint')
