You can find product details and the latest AMI IDs on the Amazon Linux AMI page.
Please upgrade to Amazon Linux AMI 2016.03 from earlier versions!
While older versions of the AMI and its packages will continue to be available for launch in Amazon EC2 even as new Amazon Linux AMI versions are released, we encourage users to migrate to the latest version of the AMI and to keep their systems updated. In some cases, customers seeking support for an older version of the Amazon Linux AMI through AWS Support may be asked to move to newer versions as part of the support process.
To upgrade to Amazon Linux AMI 2016.03 from 2011.09 or later, run sudo yum update. When the upgrade is complete, reboot your instance.
Remember that the Amazon Linux AMI repository structure is configured to deliver a continuous flow of updates that allow you to roll from one version of the Amazon Linux AMI to the next. Please consult our lock-on-launch FAQ for a discussion of how you can lock an instance (either a new launch or one already running) to a particular version of the Amazon Linux AMI repositories.
Released on June 28th, 2016
- We've added support for the newly launched Elastic Network Adapter (ENA), the next generation network interface for EC2 instances, including version 0.6.6 of the open source ENA drivers.
Released on June 9th, 2016
- We've updated the base AMI to include all bugfix and security updates that have been made available in our repositories since the 2016.03.1 point release.
- This point release includes the 4.4.11 kernel.
- The Amazon Linux AMI with NVIDIA GRID GPU Driver now includes NVIDIA driver version 352.79 and CUDA 7.5.18.
Released on May 4th, 2016
- We've updated the base AMI to include all bugfix and security updates that have been made available in our repositories since the 2016.03 release.
- This point release includes the 4.4.8 kernel.
- We've made a number of changes that improve AMI reboot time performance.
Having spent the past release tracking the 4.1 kernel series, for this release we have moved the kernel to version 4.4, which is the most recent long-term stable release kernel.
The SSLv3 protocol has been disabled by default in OpenSSL in favor of TLS. Server applications that have SSL/TLS protocol lists in their configuration have been updated to exclude SSLv3 by default.
For this release, SSLv3 support has not been entirely removed from any cryptographic libraries, so you can override this decision on an application-by-application basis, where supported.
SSL-related changes to individual applications are described below:
We've changed the default DNS resolution options from 2 retries with a 5 second timeout to 5 retries with a 2 second timeout.
Retries for DNS resolution in glibc are configured to happen faster because the distance to the EC2 resolvers is known to be short. This is configured in the AMI rather than in a package, so the change is not brought in unexpectedly by a yum update.
To apply the same change to existing instances, append the options to the appropriate configuration files:
$ echo 'RES_OPTIONS="timeout:2 attempts:5"' | sudo tee -a /etc/sysconfig/network-scripts/ifcfg-eth0 $ echo 'options timeout:2 attempts:5' | sudo tee -a /etc/resolv.conf
In this release, NUMA balancing has been disabled by default in the kernel to avoid unexpected performance degradation. This change only affects instance types which support NUMA, listed below.
If you prefer the previous behavior, you can enable the feature using sysctl:
$ sudo sysctl -w 'kernel.numa_balancing=1' $ echo 'kernel.numa_balancing = 1' | sudo tee /etc/sysctl.d/50-numa-balancing.conf
Having been in the preview repository since our 2015.09 release, OpenLDAP 2.4.40 is now available in the main repository. In addition to numerous bug fixes and stability enhancements, OpenLDAP now supports the Lightning Memory-Mapped Database (LMDB) format.
While Ruby 2.0 remains our default Ruby interpreter, we have added ruby23 packages to this Amazon Linux AMI release. Core rubygems have also been updated.
We continue to track upstream releases of the Rust compiler, and in this release we've included version 1.7. You can install the Rust compiler by running sudo yum --enablerepo=amzn-preview install rust
Update 2016-06-08: Rust 1.9 is now available in our preview repository.
Many of our packages have been re-synced to newer upstream versions. Some of the more popular packages in 2016.03 are:
This compatibility table shows which Amazon Linux AMI flavors are recommended for each EC2 instance type.
The Amazon Linux AMI FAQs is updated with both general and technical topics.
We use the Amazon EC2 Discussion Forum for bug reports, feature requests, and package requests. These forums are monitored by AWS Developer Support as well as the Amazon Linux AMI engineering team.
We are actively hiring Linux Systems Engineer, Linux Software Development Engineer, and Linux Kernel Engineer positions! :-)
