AWS Systems Manager Agent (SSM Agent) is Amazon software that can be installed and configured on an Amazon EC2 instance, an on-premises server, or a virtual machine (VM). SSM Agent makes it possible for Systems Manager to update, manage, and configure these resources. The agent processes requests from the Systems Manager service in the AWS Cloud, and then runs them as specified in the request. SSM Agent then sends status and execution information back to the Systems Manager service by using the Amazon Message Delivery Service (service prefix: ec2messages).
If you monitor traffic, you will see your Amazon EC2 instances, and any on-premises servers or VMs in your hybrid environment, communicating with ec2messages.* endpoints. For more information, see Reference: ec2messages, ssmmessages, and Other API Calls. For information about porting SSM Agent logs to Amazon CloudWatch Logs, see Monitoring AWS Systems Manager.
Keeping SSM Agent up-to-date
An updated version of SSM Agent is released whenever new capabilities are added to Systems Manager or updates are made to existing capabilities. If an older version of the agent is running on an instance, some SSM Agent processes can fail. For that reason, we recommend that you automate the process of keeping SSM Agent up-to-date on your instances. For information, see Automate Updates to SSM Agent. To be notified about SSM Agent updates, subscribe to the SSM Agent Release Notes page on GitHub.
Note
This is a quick guide to installing the following in CentOS 7: ffmpeg flvtool2 mp4box imagemagick CentOS 7 requires a tweak to the process I’d used for CentOS 6. The links below are generally suitable for EL7. We need someone who can install a free and simple control panel on a Digital Ocean Ubuntu droplet that allows us at least to use a file manager and create fresh databases to install Wordpress.
AMIs that include SSM Agent by default can take up to two weeks to be updated with the newest version of SSM Agent. We recommend that you configure even more frequent automated updates to SSM Agent.
To install Flvtool2, you need to have Ruby installed (Please look at our other article on how to install Ruby). After you have Ruby installed, do the following via putty.
Updated versions of SSM Agent are rolled out to new AWS Regions at different times. For this reason, you might receive the 'Unsupported on current platform' error when trying to deploy a new version of SSM Agent in a Region.
About the local ssm-user account
Starting with version 2.3.50.0 of SSM Agent, the agent creates a local user account called ssm-user and adds it to /etc/sudoers (Linux) or to the Administrators group (Windows). On agent versions before 2.3.612.0, the account is created the first time SSM Agent starts or restarts after installation. On version 2.3.612.0 and later, the ssm-user account is created the first time a session is started on an instance. This ssm-user is the default OS user when a Session Manager session is started. You can change the permissions by moving ssm-user to a less-privileged group or by changing the sudoers file. The ssm-user account is not removed from the system when SSM Agent is uninstalled.
On Windows Server, SSM Agent handles setting a new password for the ssm-user account when each session starts. No passwords are set for ssm-user on Linux managed instances.
Starting with SSM Agent version 2.3.612.0, the ssm-user account is not created automatically on Windows Server machines that are being used as domain controllers. To use Session Manager on a Windows Server domain controller, you must create the ssm-user account manually if it isn't already present.
Important
In order for the ssm-user account to be created, the instance profile attached to the instance must provide the necessary permissions. For information, see Verify or Create an IAM Instance Profile with Session Manager Permissions.
AMIs with SSM Agent preinstalled
SSM Agent is preinstalled, by default, on the following Amazon Machine Images (AMIs):
Windows Server 2003-2012 R2 AMIs published in November 2016 or later
Windows Server 2016 and 2019
Amazon Linux
Amazon Linux 2
Ubuntu Server 16.04
Ubuntu Server 18.04
You must manually install SSM Agent on Amazon EC2 instances created from other Linux AMIs, including non-base images like Amazon ECS-Optimized AMIs. You must also manually install SSM Agent on on-premises servers or VMs in your hybrid environment. For more information, see Setting Up AWS Systems Manager for Hybrid Environments.
SSM Agent on GitHub
The source code for SSM Agent is available on GitHub so that you can adapt the agent to meet your needs. We encourage you to submit pull requests for changes that you would like to have included. However, Amazon Web Services does not currently provide support for running modified copies of this software.

I've searched and googled but I could not find much in the way of installing, setting up and testing ffmpeg/flvtool2 on Windows when it is to be used with PHP for a website.Can one of you who's already done this help me, please
I am putting together a website that will let users upload small videos so they can be streamed on the website but I can't get a particular script to work. It does not even recognize the paths to ffmpeg or flvtool2.
The server is Windows 2003 R2 running Apache 2.20 and PHP 5.3.8. I found the correct binaries of ffmpeg and flvtool2 and I have installed them. I also installed ffmpeg-php and loaded the extension.
Below is a screencap of phpinfo():
The paths below are correct and also come from phpinfo():
C:ffmpegbin;C:flvtool2bin;C:ffmpegffmpeg-php
If I use the following script to test ffmpeg, it works:
<?php
$ffmpegpath = 'ffmpeg.exe';
$input = '1.mp4';
$output = '1.jpg';
if (make_jpg($input, $output)){
echo 'success';
}else{
echo 'bah!';
}
function make_jpg($input, $output, $fromdurasec='01') {
global $ffmpegpath;
if(!file_exists($input)) return false;
$command = '$ffmpegpath -i $input -an -ss 00:00:$fromdurasec -r 1 -vframes 1 -f mjpeg -y $output';
@exec( $command, $ret );
if(!file_exists($output)) return false;
if(filesize($output)0) return false;
return true;
}
?>
I don't know PHP or ffmpeg/flvtool2 well enough to write it myself. I've already tried but it did not work and I don't know if it's because something is wrong with my installation or the coding. I need something that's proven to work.
The problem I have with the video sharing script I want to use is that the script does seem to like the path to ffmpeg or flvtool2 so I can't even get past the first step to setting it up.
