linux – mongodb EBS on EC2

我在ec2上使用 mongodb和nodejs,我想部署它以便每天支持10,000个请求.
我想确保如果实例终止或重新启动(？),数据库将不会丢失.
我知道我需要创建一个用于存储数据的EBS卷.

我尝试了http://www.mongodb.org/display/DOCS/Amazon+EC2+Quickstart#AmazonEC2Quickstart-ConfigureStorage,但它没有用.我到了应该跑的地步
[ec2-user @ domU -…〜] $sudo chown mongod：mongod / data
但我得到：
chown：用户无效：`mongod：mongod’

解决了它：sudo chown mongod.mongod / data
仍然无法运行mongod工作：

$sudo /etc/init.d/mongod start
Starting mongod: forked process: 1694
all output going to: /log/mongod.log
                                                           [Failed][ec2-user@domU-... /]$sudo mongod --dbpath=/data

我不理解指南中的一个词……只有我……？是否有更简单易懂的指南来实现这一目标？
谢谢！

解决方法

我遇到的问题描述如下：
http://doubleclix.wordpress.com/2012/05/04/notes-on-mongo-at-aws/

最后我按照指南：
http://d36cz9buwru1tt.cloudfront.net/AWS_NoSQL_MongoDB.pdf

而mongo正在运行！
除了根卷ebs之外,我只创建了一个EBS(20 GiB)并将其安装到/ data / db

我希望我的部署能够在每天使用nodejs和10,000个客户端请求时正常工作.
(如果我错了,或者有人对我所描述的部署有任何建议,我会非常感激)

谢谢
