Allowing Apache on EC2 to run sudo commands via CGI script

阅读更多关于 Allowing Apache on EC2 to run sudo commands via CGI script

R + httr and EC2 api authentication issues

阅读更多关于 R + httr and EC2 api authentication issues

问题 I would like to use the R package httr to access the EC2 services via their API. But I am a little bit unsure how to get started as it does not fall into the usual authentication format of "Oauth2.0" in which you have the usual: key, secret, token and signature system. I think EC2 uses the "signature version 2" method, but I am unclear as to how that works. Looking at the documentation that EC2 provides with regard to making query requests at http://docs.amazonwebservices.com/AWSEC2/latest

How do I save an AMI to a S3 bucket?

阅读更多关于 How do I save an AMI to a S3 bucket?

I've created an AMI(EBS AMI) using the Amazon AWS console. That AMI has 2 snapshots attached to it. Now I want to backup that AMI to a S3 bucket. Is this possible? I actually need to do this to be able to then move that AMI to a bucket in a different region and register that AMI for use in that different region. Any clues? Update My initial answer still applies concerning the question as such (see below), however, given you actually need to do this to be able to then move that AMI to [...] a different region , you will be pleased that AWS has just released Cross Region EC2 AMI Copy to address
