How to Determine If Your AWS Instance is Running Amazon Linux 1 or 2
How to Determine If Your AWS Instance is Running Amazon Linux 1 or 2
In the realm of cloud computing, Amazon Web Services (AWS) ranks at the top. AWS offers a multitude of services, including Elastic Compute Cloud (EC2), which allows you to set up virtual machines or instances with a wide range of operating systems. Among these, Amazon Linux, a Linux server operating system from AWS, is a popular choice. However, there are two versions of this OS: Amazon Linux 1 and Amazon Linux 2. In this article, we’ll be exploring how to determine whether your AWS instance is running Amazon Linux 1 or 2.
The Importance of Identifying Your Amazon Linux Version
Before we delve into the ‘how’, let’s briefly discuss the ‘why’. Amazon Linux 2, the latest version, offers several improvements over its predecessor, including long term support, a more modern kernel, and compatibility with the Amazon System Manager. However, some applications designed for the original Amazon Linux may not run as smoothly on Amazon Linux 2. Therefore, knowing your Amazon Linux version is crucial for debugging, maintenance, and application compatibility purposes.
Identifying Your Amazon Linux Version
Now, let’s move on to the meat of the matter: determining your Amazon Linux version. You can do this through the AWS Management Console, or by running a command in the instance itself.
Via AWS Management Console
The AWS Management Console allows you to manage your AWS resources in a user-friendly interface. Follow these steps to identify your Amazon Linux version:
- Login to your AWS Management Console.
- Navigate to the EC2 Dashboard.
- In the sidebar, click on ‘Instances’.
- Select the instance you want to check.
- In the ‘Description’ tab below, locate the ‘AMI ID’. The AMI ID will hint at the Amazon Linux version used. For example, an AMI ID starting with ‘ami-0a887e401f7654935’ likely points to Amazon Linux 2, while ‘ami-0b898040803850657’ indicates Amazon Linux 1.
Via Command Line
If you’re more comfortable with the command line or need to script this check, you can run a command directly in your instance. SSH into your instance and use the following command:
cat /etc/system-release
The output will specify the Amazon Linux version. For Amazon Linux 2, you’ll see something like ‘Amazon Linux release 2’. On the other hand, if you’re running Amazon Linux 1, the output will be ‘Amazon Linux AMI release 2018.03’, or similar.
Conclusion
Identifying the Amazon Linux version of your AWS instance is a simple but important task. Whether you’re a seasoned data scientist or a budding software engineer, understanding your operating environment is crucial for effective development and problem-solving. By using the AWS Management Console or the command line, you can quickly and accurately determine whether you’re dealing with Amazon Linux 1 or 2.
Remember: knowing your tools is half the battle. Stay curious, and keep exploring!
