  • php convert images and upload to amazon s3

    - by faraklit
    I am looking for a best practice while uploading images to amazon s3 server and serving from there. We need four different sizes of an image. So just after image upload we convert the image and scale in 4 different widths and heights. And then we send them to the amazon s3 using official php api. // ... // image conversions, bucket setting, s3 initialization etc. $sizes= array("", "48", "64", "128"); foreach($sizes as $size) { $filename = $upload_path.$dest_file.$size.$ext; $s3->batch()->create_object($bucket, , array( 'fileUpload' => $filename, 'acl' => AmazonS3::ACL_PUBLIC, )); } But for a 1M image the client sometimes wait up to 30 seconds which is a very long time. Instead of sending images immediately to S3, it may be better to add them to a job queue. But the user should see the uploaded image immediately.

  • Correct Path for Git Remote Add from Amazon EC2 Instance to OSX Client Machine

    - by filmnut
    I'm trying to do a git remote add from a repository that sits on a remote Amazon AMI back to a cloned copy of the SAME repository that is sitting on my local OSX machine. I'm confused about what file path to use. I assume it's something like: git remote add my_clone <OSX_User_Name>@<OSX_HOST_NAME>:<PATH_TO_CLONED_REPO> I obviously know what my <OSX_User_Name> is, and I can figure out my <PATH_TO_CLONED_REPO>, but I have no idea how to determine a <OSX_HOST_NAME> that would actually work. Can I just put in my external IP address, followed by my machine's internal IP address? (Note that I'm working behind a router.) Is ssh:// the correct protocol? Do I need to set up ssh access from the Amazon EC2 machine to the local OSX machine?

  • apache2 is making my amazon ec2 unavailable, any ideas?

    - by Tim
    I have a web server running on a EC2 c1.medium intance. The instance is running on ubuntu, with apache2 and mysql.The ubuntu and apache version are the next; Ubuntu DISTRIB_ID=Ubuntu DISTRIB_RELEASE=11.04 DISTRIB_CODENAME=natty DISTRIB_DESCRIPTION="Ubuntu 11.04" Apache2 Server version: Apache/2.2.17 (Ubuntu) Server built: Feb 22 2011 18:33:02 Sometimes randomly, my server "hangs up", I cannot connect to it using normal web access or ssh access. If I reboot the instance it reboots fine, the amazon system log doesn't show anything weird, but the problem persists The only way to solve it its stopping the instance, and start it again. I think that the problem its has something to do with apache, because the last lines of the error log lists: normal errors [Sun Jun 19 06:25:09 2011] [notice] Apache/2.2.17 (Ubuntu) PHP/5.3.5-1ubuntu7.2 with Suhosin-Patch configured -- resuming normal operations nobody cant connetc... no more erros until i stop and start the instance normal errors [Wed Jun 22 14:21:18 2011] [notice] Apache/2.2.17 (Ubuntu) PHP/5.3.5-1ubuntu7.2 with Suhosin-Patch configured -- resuming normal operations nobody cant connetc... no more erros until i stop and start the instance Can somebody please help me?

  • Shorten Long DNS names

    - by user32425
    Hi, Amazon gives us a very long dns names i.e. c-123-123-123-255.compute-1.amazonaws.com Is there a way to map this name into a shorter name i.e. essentially what i want to do is to modify /etc/hosts file, and map the long name into a short one, i.e. aws1 c-123-123-123-255.compute-1.amazonaws.com but because /etc/hosts file only accepts ip address mapping, then I cannot do that. Is there any other way to do this? Thanks

  • Read Linux-formatted (ext3) EBS volume mounted on Windows Server 2008 instance

    - by Greg Owen
    I've got a Windows Server 2008 R2 instance set up in Amazon EC2. I've also got some Ubuntu instances on the same EC2 account. I'd like to be able to mount the EBS volume from one of the Ubuntu instances onto the Windows instance as an external drive and then access that drive from the Windows instance. I've looked at tools like ext2fsd and ext2 IFS, but these haven't worked (I couldn't get the former to work, and the latter says that it supports Windows 2008 but gives an error when I try to install it, saying that it only supports up to Windows 2003). I know that there are all kinds of tools to view Linux partitions and that there are filesystems that are compatible with both Linux and Windows, but neither of those options works here (I want to be able to attach and detach the Ubuntu volumes on command, rather than have a permanent partition, and Ubuntu EBS volumes are ext3 by default). Anybody know a good tool I should use?

  • Create Webmin user for an EC2 Instance

    - by Dean
    I've setup an Amazon EC2 Instance, using the Ubuntu 12.04 AMI (ubuntu/images/ebs/ubuntu-precise-12.04-amd64-server-20120424 (ami-a29943cb)), and I'd like to get Webmin working (so I can setup a DNS). After following the installation instructions on Webmin's site, the installer says I can login with any username/pass of a user who has superuser access. The problem is that the EC2 instance only has 1 user "ubuntu", which can only login using SSH keys -- not a password! I've tried creating users manually and I can't login as those users (even via SSH), so I think it might be a permission thing provided by the AMI. Does anyone know the best way around setting up a login to my webmin?

  • Securing ClickOnce hosted with Amazon S3 Storage

    - by saifkhan
    Well, since my post on hosting ClickOnce with Amazon S3 Storage, I've received quite a few emails asking how to secure the deployment. At the time of this post I regret to say that there is no way to secure your ClickOnce deployment hosted with Amazon S3. The S3 storage is secured by ACL meaning that a username and password will have to be provided before access. The Amazon CloudFront, which sits on top of S3, allows you to apply security settings to your CloudFront distribution by Applying an encryption to the URL. Restricting by IP. The problem with the CloudFront is that the encryption of the URL is mandatory. ClickOnce does not provide a way to pass the "Amazon Public Key" to the CloudFront URL (you probably can if you start editing the XML and HTML files ClickOnce generate but that defeats the porpose of ClickOnce all together). What would be nice is if Amazon can allow users to restrict by IP addresses or IP Blocks. I'd sent them an email and received a response that this is something they are looking into...I won't hold my breadth though. Alternative I suggest you look at Rack Space Cloud hosting http://www.rackspacecloud.com they have very competitive pricing and recently started hosting Windows Virtual Servers. What you can do is rent a virtual server, setup IIS to host your ClickOnce applications. You can then use IIS security setting to restrict what IP/Blocks can access your ClickOnce payloads. Note: You don't really need Windows Server to host ClickOnce. Any web server can do. If you are familiar with Linux you can run that VM with rackspace for half the price of Windows. I hope you found this information helpful.

  • Sending mail via php in EC2

    - by william007
    I have used the following code for sending mail using php using amazon ec2, but I only see 'aatest' as the result, and doesn't get any incoming email. Btw, I have already included ses.php, and have validated the email [email protected], and double confirm that accesskey, and accesskey are the correct one. Can anyone suggest way for debugging it? require_once('ses.php'); $con=new SimpleEmailService('accesskey','accesskey'); print_r('aa'.$con->listVerifiedEmailAddresses()); $m = new SimpleEmailServiceMessage(); $m->addTo('[email protected]'); $m->setFrom('[email protected]'); $m->setSubject('Hello, world!'); $m->setMessageFromString('This is the message body.'); print_r($con->sendEmail($m)); echo 'test';

  • Transparent Technology from Amazon

    - by David Dorf
    Amazon has been making some interesting moves again, this time in the augmented humanity area.  Augmented humanity is about helping humans overcome their shortcomings using technology.  Putting a powerful smartphone in your pocket helps you in many ways like navigating streets, communicating with far off friends, and accessing information.  But the interface for smartphones is somewhat limiting and unnatural, so companies have been looking for ways to make the technology more transparent and therefore easier to use. When Apple helped us drop the stylus, we took a giant leap forward in simplicity.  Using touchscreens with intuitive gestures was part of the iPhone's original appeal.  People don't want to know that technology is there -- they just want the benefits.  So what's the next leap beyond the touchscreen to make smartphones even easier to use? Two natural ways we interact with the world around us is by using sight and voice.  Google and Apple have been using both in their mobile platforms for limited uses cases.  Nobody actually wants to type a text message, so why not just speak it?  Any if you want more information about a book, why not just snap a picture of the cover?  That's much more accurate than trying to key the title and/or author. So what's Amazon been doing?  First, Amazon released a new iPhone app called Flow that allows iPhone users to see information about products in context.  Yes, its an augmented reality app that uses the phone's camera to view products, and overlays data about the products on the screen.  For the most part it requires the barcode to be visible to correctly identify the product, but I believe it can also recognize certain logos as well.  Download the app and try it out but don't expect perfection.  Its good enough to demonstrate the concept, but its far from accurate enough.  (MobileBeat did a pretty good review.)  Extrapolate to the future and we might just have a heads-up display in our eyeglasses. The second interesting area is voice response, for which Siri is getting lots of attention.  Amazon may have purchased a voice recognition company called Yap, although the deal is not confirmed.  But it would make perfect sense, especially with the Kindle Fire in Amazon's lineup. I believe over the next 3-5 years the way in which we interact with smartphones will mature, and they will become more transparent yet more important to our daily lives.  This will, of course, impact the way we shop, making information more readily accessible than it already is.  Amazon seems to be positioning itself to be at the forefront of this trend, so we should be watching them carefully.

  • Need advise on choosing aws EC2

    - by Mayank
    I'm planning to host a website where in the first phase I would target 30,000 users. It is in php and runs on Apache server. I'm assuming 8,000 users can be online in worst case scenario and 1000 of them will be uploading photographs. A photograph will be resized to around 1MB at client side and one HTTP request is uploading only one photograph. My plan: 2 Small EC2 instances to run Apache httpd 2 Small EC2 instances to DB (Postgresql). I to write data and other its read replica. EBS volumes for DBs Last, Amazon S3 for uploaded photographs. My question here Is Small EC2 instance more than what I require. I mean should I go for micro Is 8000 simultaneous user a right no. (to decide what EC2 instance to choose) for a new website Or should I go for Small instance so to make it capable of spikes

  • How can I limit CloudFront downloads

    - by Alex Crouzen
    I'm looking to use Amazon's CloudFront to host some content in the near future. Currently, I'm keeping it very simple and I'm just uploading my content to S3 and then making a distribution available via Cloudfront. However, because I have a limited budget, I'd like to be able to limit the number of downloads or the money spent on bandwidth. As far as I can see, I can't set any quotas or budgets like you can in Google's App Engine, so I'm looking for another way of doing this. Has anyone had any experience doing this? One approach I'm thinking of is having to place a webserver with redirects in between, but that kind of defeats the simplicity of CF for me.

  • Spawn phone call from EC2 alerts

    - by Matt
    I have a system setup on AWS/EC2, it currently is using their CloudWatch alert system. The problem is this sends just to email, when ideally I would like this to be making a phone call and/or sending text messages to certain phone numbers when an alert fires (Note that I do not need the phone call to actually say anything, just call the person). We are trying to solve the problem that Amazon alerts are only useful if people are checking their email, which isnt always the case because all server problems love to happen at 4am on saturday... Please respond with any possible solutions/ideas, ideally I do not want to implement an entire monitoring system (IE: Nagios) on top of everything to handle this.

  • Can't star SSH on Ubuntu 12.10 AWS EC2

    - by Conor H
    So i've just started playing around with Ubuntu on Amazon EC2. I've just issued the following command to restart ssh but it has now "killed" ssh. sudo /etc/init.d/ssh restart I can't seem to ssh to this instance anymore. Putty just gives me "connection refused". NOTE: In this case I just restarted SSH to see the result. I didn't change any settings. This was to confirm that it was the restart command was the problem and not any configs I made. What is the correct way to restart SSH? P.S. That usually works on other Ubuntu boxes. Thanks. EDIT: It is also worth noting that when I ran that command I was taken straight back to a prompt. I didn't get any output on the console.

  • Which AMI should I use as a base for a Django application?

    - by Edan Maor
    I'm starting development of a Django application, on Amazon's Web Services. I'm looking to build an instance that will serve the Django. I don't have much experience with such things, having only used a shared host before (WebFaction). So I'm wondering, which AMI should I use as a base? I'm assuming I want an Ubuntu AMI, possibly with certain things like Apache pre-installed? One minor point: I'm planning to serve several different Django projects from the same instance. I use virtualenv on my dev machine right now to separate the different projects, I'm assuming I'll do the same on EC2. Thanks!

  • Copy/move EBS volume from one Region to another

    - by Gnanam
    Background of our setup: We've hosted our web-based application in Amazon EC2 US East (Virginia) Region. Our instance is based on Linux distribution (CentOS) and AMI is S3-backed. 1 EBS volume (400 GB size) is attached to this instance. Question: We've planned to migrate our deployment to US West (N. California) Region. From AWS doc, I understood that for moving AMI, there is a command-line tool available - ec2-migrate-bundle. But for moving EBS volume across Region, currently there is no tool available. I'm looking for easiest and/or fastest way of copying/moving EBS volume from one Region to another. Also, are there any hidden risks involved during and/or after the migration? Experts ideas/suggestions/recommendations on this are highly appreciated.

  • AWS RDS Timeout

    - by warder57
    I know next to nothing about networking/servers. So I'm assuming I'm missing something obvious. All of the resources I can find on this, either don't work or are outdated. I created a brand new AWS account on the free plan. I created a postgres RDS DB instance. I made sure that this RDS instance is set to publicly accessible. This RDS instance has the default VPC/Security Group settings. In order to connect to this DB from my local machine, I used pgadmin3 and followed the instructions provided on the AWS documentation page. Seen here: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ConnectToPostgreSQLInstance.html I've double checked all of the information required to connect: Host: whatever.whatever.us-west-2.rds.amazonaws.com Port: 5432 Username: USERNAME Password: PASSWORD When I try to connect to the database, my connection fails due to a timeout. (During step 4 in the above guide.) Can anyone point me to whatever I am missing? Thanks in advance

  • RDS Replication across regions

    - by Bryan Migliorisi
    We are using Amazon AWS for our web services but given the recent instabilities in their infrastructure, we are trying to figure out how to run our application across multiple regions for additional redundancy. Ideally, we would run our entire app in a active-active configuration in multiple regions but our main concern is that we are using RDS, which I understand cannot replicate across regions. One possible solution (though we have not tried or proven it would work) would be to do mysqldump or EBS snapshots every hour or so but this would mean that we would be forced to run in an active-passive configuration. Our data would be at most an hour behind. This carries its own issues around data synchronization when we failover and the master comes back up, so its not the best solution. Are there any proven solutions for replicating RDS across regions?

  • Does setting an A record for a root domain set it (automatically) for subdomains?

    - by Edan Maor
    I bought a domain from Dreamhost, but my servers are actually running on Amazon's AWS. I have an Elastic IP, say 1.1.1.1. In the Dreamhost panel, I've added an A record for my domain name, pointing it to 1.1.1.1. My question is, are all subdomains (e.g. www.mydomain.com, a.mydomain.com, etc.) automatically mapped to 1.1.1.1 as well, because the root is? Or do I have to add separate rules for each subdomain?

  • How do you keep up with Nagios/Capistrano configs when using EC2?

    - by imaginative
    I use Amazon EC2 for my mobile app. Depending on load of the application at a given time, I might spawn new instances and then take them down when load is lower to save costs. How does one keep up with Nagios configurations for such a dynamic environment? When one deals with managed hardware, configuration files are predictable. In this case Nagios, Capistrano and a bunch of other configuration files would need to be added. Capistrano needs to know where to deploy a new build to for an app server. Nagios needs to know to remove an existing instance or add a new instance for monitoring. Nagios also needs to know if a node was intentionally taken down or if the host is down due to error. How is this done with the wonderful world of VPS/dynamic instances?

  • Why S3 website redirect location is not followed by CloudFront?

    - by ychaze
    I have a website hosted on Amazon S3. It is the new version of an old website hosted on WordPress. I have set up some files with the metadata Website Redirect Locationto handle old location and redirect them to the new website pages. For example: I had http://www.mysite.com/solution that I want to redirect to http://mysite.s3-website-us-east-1.amazonaws.com/product.html So I created an empty file named solutioninside my bucket with the correct metadata: Website Redirect Location= /product.html The S3 redirect metadata is equivalent to a 301 Moved Permanentlythat is great for SEO. This works great when accessing the URL directly from S3 domain. I have also set up a CloudFront distribution based on the website bucket. And when I try to access through my distribution, the redirect does not work, ie: http://xxxx123.cloudfront.net/solution does not redirect but download the empty file instead. So my question is how to keep the redirection through the CloudFront distribution ? Or any idea on how to handle the redirection without deteriorate SEO ? Thanks
