Amazon Linux AMI 2012.09 Release Notes
Upgrading to Amazon Linux AMI 2012.09
Think about migrating to Amazon Linux AMI 2012.09 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 newer versions 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 Amazon Premium Support may be asked to move to newer versions as part of the support process.
To upgrade to Amazon Linux AMI 2012.09 from 2012.03, 2011.09 or 2011.02, run
. When the transaction is complete, reboot your instance.
The Amazon Linux AMI 2012.09.1 point release shipped with kernel version 3.2.38, replacing the 3.2.30 kernel that shipped with the initial Amazon Linux AMI 2012.09.
Apache 2.4 & PHP 5.4
This release supports multiple versions of both Apache and PHP, and they are engineered to work together in specific combinations. The first combination is the default, Apache 2.2 in conjunction with PHP 5.3, which are installed by running
yum install httpd php
. Based on customer requests, we support Apache 2.4 in conjunction with PHP 5.4 in the package repositories. These packages are accessed by running
yum install httpd24 php54
While OpenJDK 1.6 is still installed by default on the AMI, OpenJDK 1.7 is included in the package repositories, and available for installation. You can install it by running
yum install java-1.7.0-openjdk
Also coming from your requests, we have added the R language to the Amazon Linux AMI. We are here to serve your statistical analysis needs! Simply
yum install R
and off you go.
Multiple versions of GCC
The default version of GCC that is available in the package repositories is GCC 4.6, which is a change from the 2012.03 AMI in which the default was GCC 4.4 and GCC 4.6 was shipped as an optional package. Furthermore, GCC 4.7 is available in the repositories. If you
yum install gcc
you will get GCC 4.6. For the other versions, either run
yum install gcc44
yum install gcc47
Multiple Interfaces & IP Addresses:
Additional network interfaces attached while the instance is running will be configured automatically. Secondary IP addresses will be refreshed during DHCP lease renewal, and the related routing rules will be updated.
This functionality is provided by the
package, which can be removed if manual control over network configuration is required.
We have included updated versions of all the AWS command line tools that are part of the Amazon Linux AMI. See the 2012.09 package list
for more details.
CUDA toolkit 4.2.9
The CUDA toolkit version 4.2.9 is available on the Cluster GPU AMI.
Many of the packages in the AMI have been re-synced to their latest upstream version. For reference, we have produced a list of all source RPMs
included in Amazon Linux AMI 2012.09.
