Manually install SSM Agent on Rocky Linux instances

The Amazon Machine Images (AMIs) for Rocky Linux that are provided by Amazon do not come with Amazon Systems Manager Agent (SSM Agent) preinstalled by default. For a list of Amazon managed AMIs on which the agent might be preinstalled, see Amazon Machine Images (AMIs) with SSM Agent preinstalled.

Use the information in this section to help you manually install or reinstall SSM Agent on an Rocky Linux instance.

Before you begin

Before you install SSM Agent on a Rocky Linux instance, note the following:

Quick installation commands for SSM Agent on Rocky Linux

Use the following steps to manually install SSM Agent on a single instance. This procedure uses globally available installation files.

Before you begin

Before you install SSM Agent on a Rocky Linux instance, note the following:

  • Ensure that either Python 2 or Python 3 is installed on your Rocky Linux instance. This is required in order for SSM Agent to work properly.

To install SSM Agent on Rocky Linux

  1. Connect to your Rocky Linux instance using your preferred method, such as SSH.

  2. Copy the command for your instance’s architecture and run it on the instance.

    Note

    Even though URLs in the following commands include an ec2-downloads-windows directory, these are the correct global installation files for Rocky Linux.

    x86_64 instances
    sudo dnf install -y https://s3.amazonaws.com/ec2-downloads-windows/SSMAgent/latest/linux_amd64/amazon-ssm-agent.rpm
    ARM64 instances
    sudo dnf install -y https://s3.amazonaws.com/ec2-downloads-windows/SSMAgent/latest/linux_arm64/amazon-ssm-agent.rpm

  3. (Recommended) Run the following command to verify that the agent is running.

    sudo systemctl status amazon-ssm-agent

    In most cases, the command reports that the agent is running, as shown in the following example.

    ● amazon-ssm-agent.service - amazon-ssm-agent
   Loaded: loaded (/etc/systemd/system/amazon-ssm-agent.service; enabled; vendo>
   Active: active (running) since Tue 2022-04-19 16:40:41 UTC; 9s ago
 Main PID: 4898 (amazon-ssm-agen)
    Tasks: 14 (limit: 4821)
   Memory: 34.6M
   CGroup: /system.slice/amazon-ssm-agent.service
           ├─4898 /usr/bin/amazon-ssm-agent
           └─4954 /usr/bin/ssm-agent-worker
            --truncated--

    In rare cases, the command reports that the agent is installed but not running, as shown in the following example.

    ● amazon-ssm-agent.service - amazon-ssm-agent
   Loaded: loaded (/etc/systemd/system/amazon-ssm-agent.service; enabled; vendo>
   Active: inactive (dead) since Tue 2022-04-19 16:42:05 UTC; 2s ago
            --truncated--

    To activate the agent in these cases, run the following commands.

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

Create custom agent installation commands for Rocky Linux in your Region

When you install SSM Agent on multiple instances using a script or template, we recommended using installation files that are stored in the Amazon Web Services Region you're working in.

For the following commands, we provide examples that use a publicly accessible S3 bucket in the US East (Ohio) Region (us-east-2).

Tip

You can also replace a global URL in the procedure Quick installation commands for SSM Agent on Rocky Linux earlier in this topic with a custom Regional URL you construct.

In the following command, replace region with your own information. For a list of supported region values, see the Region column in Systems Manager service endpoints in the Amazon Web Services General Reference.

x86_64
sudo dnf install -y https://s3.region.amazonaws.com/amazon-ssm-region/latest/linux_amd64/amazon-ssm-agent.rpm

See the following example.

sudo dnf install -y https://s3.us-east-2.amazonaws.com/amazon-ssm-us-east-2/latest/linux_amd64/amazon-ssm-agent.rpm
ARM64
sudo dnf install -y https://s3.region.amazonaws.com/amazon-ssm-region/latest/linux_arm64/amazon-ssm-agent.rpm

See the following example.

sudo dnf install -y https://s3.us-east-2.amazonaws.com/amazon-ssm-us-east-2/latest/linux_arm64/amazon-ssm-agent.rpm
