Manually installing SSM Agent on Red Hat Enterprise Linux instances - AWS Systems Manager

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

Use the information in this section to help you manually install or reinstall SSM Agent on a RHEL instance.

Before you begin

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

  • For important information that applies to installation of SSM Agent on all Linux-based operating systems, see Manually installing and uninstalling SSM Agent on EC2 instances for Linux.

  • If you use a yum command to update SSM Agent on a managed node after the agent has been installed or updated using the SSM document AWS-UpdateSSMAgent, you might see the following message: "Warning: RPMDB altered outside of yum." This message is expected and can be safely ignored.
