Manually installing SSM Agent on Oracle Linux instances
The Amazon Machine Images (AMIs) for Oracle 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 Find AMIs with the SSM Agent preinstalled.
Use the information in this section to help you manually install or reinstall SSM Agent on an Oracle Linux instance.
Before you begin
Before you install SSM Agent on an Oracle Linux 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 documentAWS-UpdateSSMAgent
, you might see the following message: "Warning: RPMDB altered outside of yum." This message is expected and can be safely ignored.

Create custom agent installation commands for Oracle 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
