"I want to install AWS CloudFormation helper scripts on Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and RHEL 9 Amazon Machine Images (AMIs).Short descriptionYou must install helper scripts for Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and RHEL 9 AMIs during the boot process. Use the UserData property to download and install the AMIs. Then, start the cfn-hup service at launch. To get the latest binaries of the aws-cfn-bootstrap package, see CloudFormation helper scripts reference.Resolution1.    Review the templates for Ubuntu 16.04 LTS script, Ubuntu 18.04 LTS script, Ubuntu 20.04 LTS script, Ubuntu 22.04 LTS script, on RHEL 9 script on GitHub. These scripts create a service in systemd to allow the cfn-hup helper daemon to automatically start at boot.Important: Make systemd a dependency of an existing boot target. Use multi-user.target to create the dependency.2.    Review how to define the UserData property of the instance.3.    Create the cfn-hup configuration file, cfn-hup hook, and systemd file for cfn-hup /lib/systemd/systemcfn-hup.service. Refer to the instructions that are set in the files key.4.    To activate the service in systemd and start the service, use the commands key.5.    To confirm that the cfn-hup service starts after it launches the stack, run the following command:systemctl status cfn-hupIf cfn-hup starts successfully, then you receive an output that's similar to the following one:cfn-hup.service - cfn-hup daemon   Loaded: loaded (/usr/lib/systemd/system/cfn-hup.service; enabled; vendor preset: disabled)   Active: active (running) since Wed 2016-10-12 08:10:26 EDT; 1min 11s ago MainPID: 4852 (cfn-hup)   CGroup: /system.slice/cfn-hup.service                       └─4852 /usr/bin/python /opt/aws/bin/cfn-hupOct 12 08:10:26 ip-172-31-44-180.ec2.internal systemd[1]: Started cfn-hup daemon. Oct 12 08:10:26 ip-172-31-44-180.ec2.internal systemd[1]: Starting cfn-hup daemon...Note: If you use systemd, then the cfn-init helper script doesn't support the services key. Instead, use the commands key as shown in the previous example.Related informationCFNhelpernonAMZNAMIs (GitHub)Follow"
