64-bit CentOS5 Amazon EC2 Image Release

You’ve reached an archived Flexera blog post that may be out of date. Please visit the blog homepage for the most current posts.

A 64-bit version of our CentOS5 image is now available for general consumption. The image is called `RightImage CentOS5 x86_64 V1_12` with AMI ID ami-31c72258 and location `rightscale_images/CentOS5_X86_64_V1_12`.

This is our first public image for the large instance types and we hope we covered all bases, but we’re eager to hear whether everything works as expected. As promised the script to create the image is also available. To run the script, launch Amazon’s 64-bit FC6 image and run through the steps. 

A little background on RightImages for those of you not familiar with what we’re doing: To configure servers we use a base image and install software at boot time using our server templates and RightScripts. This is way more modular and maintainable than baking entire servers into AMIs. Please see our blog post on the rationale behind this. As a result, we produce base images that are small yet have all the software utilities one just needs in EC2 already installed, from the Amazon EC2 tools to traceroute, curl, wget, etc. The second innovation we made with our images is that they are fully scripted and we publish the script. You can launch Amazon’s FC4 or FC6 image, run our script, and out pops a clone of our RightImage. So if you want to see what we install or make some changes you can go right ahead.

steve I receive msg: “Error: InvalidParameterValue: The requested instance type does not agree with the architecture specified in the AMI manifest.” when trying to launch it from the dashboard.

Morgan Tocker Is there any interest in creating a CentOS 4 server template? There are a number of isolated incidents where MySQL does not play nice with NPTL, and LinuxThreads support has been removed from CentOS 5.

Thorsten Steve: are you sure you are launching the image on a “m1.large” or “m1.xlarge” instance? Sounds like you’re trying to run it on a small instance. Morgan: to tell you the truth, we don’t have the resources to pursue CentOS4. The script we use to generate our CentOS5 image is public (see the link in the blog entry), so it should be a “simple matter” for someone else to create a CentOS4 version…

Todd I’m with Steve. Maybe I’m missing something obvious, but in the dashboard,when I’m trying to launch an image, I don’t have an option to select the type of instance (large or x-large). As a result, I get the same error as Steve.

blanquer Todd and Steve, You are right, a presentation bug slipped through that causes the instance type drop-down box to not appear in the page (in some situations)…sorry about that. We’ll deploy the new code very shortly. Thanks for the feedback!

blanquer FYI, the presentation bug was fixed the next day or so, and it’s been operational for about a week now.
