linux - EC2 上的 mongodb EBS

Question

我在 ec2 上使用 mongodb 和 nodejs，我想部署它以支持每天 10,000 个请求。我想确保如果实例终止或重新启动(？)以某种方式数据库不会丢失。我知道我需要创建一个 EBS 卷来存储数据。

我试过了 http://www.mongodb.org/display/DOCS/Amazon+EC2+Quickstart#AmazonEC2Quickstart-ConfigureStorage但它没有用。我到了我应该跑的地步[ec2-user@domU-... ~]$ sudo chown mongod:mongod/data但我得到:chown:无效用户:`mongod:mongod'

通过以下方式解决: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

我不明白指南中的一个词...只有我...吗？是否有更简单易懂的指南来实现这一目标？谢谢!

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

mongo 正在运行!除了根卷 ebs 之外，我只创建了一个 EBS (20 GiB) 并将其挂载到/data/db

我希望我的部署能够很好地处理 nodejs 和每天 10,000 个客户端请求。(如果我错了，或者如果有人对我描述的部署有任何建议，我将非常感激)

谢谢
