Amazon EC2 Windows实例中的自动挂载EBS卷

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)?

在亚马逊的弹性计算云(EC2)中启动Windows 2003实例时,是否有人知道如何自动安装弹性块存储(EBS)卷?

Setup:

Make sure the EBS volume is formatted and labeled (in the example I used the label PDRIVE).

确保EBS卷已格式化并标记(在示例中我使用了标签PDRIVE)。

Setup a drive mapping using Ec2ConfigServiceSettings.exe

使用Ec2ConfigServiceSettings.exe设置驱动器映射

Install Java on the instance

Install the EC2 API command line tools

Install a copy of your cert and private key

安装证书和私钥的副本

Install a copy of curl.exe (open source tool)

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.oncannon.net/system-administration/199/automounting-amazon-ebs-volumes-on-ec2-instances/中找到了以下Ruby代码,由Carson McDonald提供。它适用于Linux / Unix,但也许你可以在Windows 2003上为Ruby重新调整它,或者让它作为用其他脚本语言执行它的模型。

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-data to get to the user-data.

请注意,您可以将内容作为用户数据传递到图像中,例如ECS EBS卷ID和设备名称(例如,以下示例中的/ dev / sdh或适用于您的Windows中的任何内容)。您可以将实例本身的用户数据作为元数据访问,如下所示,以获取实例ID。更具体地说,您可以访问http://169.254.169.254/1.0/user-data来获取用户数据。

#!/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')
