How to Install the SSM Agent on Ubuntu EC2 Instances

Prerequisites

  • Ensure you have access to the EC2 instance, preferably via SSH.
  • Confirm whether your instance requires SSM Agent installation (some AWS AMIs come pre-installed with it).

Step-by-Step Guide

1. Connect to Your EC2 Instance:

Use SSH to connect to your EC2 instance:

ssh -i /path/to/your-key.pem ubuntu@your-ec2-public-ip

2. Create a Temporary Directory:

On your EC2 instance, create a temporary directory to store the SSM Agent installation file:

mkdir /tmp/ssm

3. Change to the Temporary Directory:

Navigate to the directory:

cd /tmp/ssm

4. Download the SSM Agent:

Depending on your system architecture, download the appropriate SSM Agent package:

  • For x86_64 Instances:
wget https://s3.amazonaws.com/ec2-downloads-windows/SSMAgent/latest/debian_amd64/amazon-ssm-agent.deb
  • For ARM64 Instances:
wget https://s3.amazonaws.com/ec2-downloads-windows/SSMAgent/latest/debian_arm64/amazon-ssm-agent.deb

5. Install the SSM Agent:

Run the following command to install the SSM Agent:

sudo dpkg -i amazon-ssm-agent.deb

6. Verify SSM Agent Status:

Check if the agent is running:

sudo systemctl status amazon-ssm-agent

The agent should be active and running. If it’s inactive, you can enable and start it manually using:

sudo systemctl enable amazon-ssm-agent
sudo systemctl start amazon-ssm-agent

That's it! The SSM Agent should now be successfully installed and running on your EC2 instance.
