在亚马逊的EC2 Windows实例中自动挂载EBS卷。

Question

有人知道如何在启动亚马逊弹性计算云（EC2）中的Windows 2003实例时自动挂载弹性块存储（EBS）卷吗？

Answer 1

设置:

• 确保EBS卷已经格式化并标记（在此示例中，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）。

您可以使用组策略编辑器将此脚本设置为启动脚本。有关更多信息，请参见http://technet.microsoft.com/en-us/library/cc739591(WS.10).aspx。

REM @echo off
REM setlocal ENABLEDELAYEDEXPANSION

C:\WINDOWS\system32\eventcreate /l SYSTEM /t information /id 100 /so AttachEbsBoot /d "Starting attach-ebs-boot.cmd"

REM local variables
REM Make sure you include the directory with curl.exe and the EC2 command line tools in the path
set path=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;c:\Utils;C:\ebin\ec2\bin
set JAVA_HOME=c:\java
set EC2_HOME=c:\ebin\ec2
set EC2_CERT=<your_cert>
set EC2_PRIVATE_KEY=<your_private_key>

REM Please note: you should use the Ec2 Config Serive Settings application to ensure
REM that your EBS volume is mapped to a particular drive letter.
REM
REM edit as needed
set EBS_DRIVE=P:
set EBS_DEVICE=xvdp

REM Test to see if the drive is already attached. If it is then we're done.
if exist %EBS_DRIVE%\nul (goto done)

REM get the EBS volume ID from the user data and the instance ID from the meta-data
for /f "delims=" %%a in ('curl http://169.254.169.254/latest/user-data') do (set EBS_VOLUME=%%a)
for /f "delims=" %%b in ('curl http://169.254.169.254/latest/meta-data/instance-id') do (set INSTANCE_ID=%%b)

C:\WINDOWS\system32\eventcreate /l SYSTEM /t information /id 102 /so AttachEbsBoot /d "Volume == %EBS_VOLUME%"
C:\WINDOWS\system32\eventcreate /l SYSTEM /t information /id 103 /so AttachEbsBoot /d "Instance == %INSTANCE_ID%"

REM attach the volume
REM 
REM Use a series of set command to build the command line
SET COMMAND_LINE=%EBS_VOLUME%
SET COMMAND_LINE=%COMMAND_LINE% -i
SET COMMAND_LINE=%COMMAND_LINE% %INSTANCE_ID%
SET COMMAND_LINE=%COMMAND_LINE% -d
SET COMMAND_LINE=%COMMAND_LINE% %EBS_DEVICE%

C:\WINDOWS\system32\eventcreate /l SYSTEM /t information /id 104 /so AttachEbsBoot /d "calling ec2attvole %COMMAND_LINE%"

call ec2attvol.cmd %COMMAND_LINE%

:DONE
C:\WINDOWS\system32\eventcreate /l SYSTEM /t information /id 101 /so AttachEbsBoot /d "Exiting attach-ebs-boot.cmd"

REM Events logged in the System event log
REM source === AttachEbsBoot
REM 
REM Event 100 - Script start
REM Event 101 - Script end
REM Event 102 - Volume ID
REM Event 103 - Instance ID
REM Event 104 - Command line for ec2attvol

Answer 2

我在http://www.ioncannon.net/system-administration/199/automounting-amazon-ebs-volumes-on-ec2-instances/上发现了以下Ruby代码，感谢Carson McDonald提供。这是为Linux/Unix编写的，但也许你可以将其重新调整为Windows 2003上的Ruby，或者将其作为在其他脚本语言中执行此操作的模型。

请注意，您可以将内容作为用户数据传递到映像中，例如ECS EBS卷ID和设备名称（例如以下示例中的/dev/sdh或适用于您情况下的Windows）。您可以从实例本身访问用户数据作为元数据，就像下面大致完成获取实例ID一样。更具体地说，您可以访问http://169.254.169.254/1.0/user-data以访问用户数据。

#!/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')
