Here's what the playbook does: The hosts line specifies the hostname of the server you want to check and start the httpd service on. become: true ensures that the playbook runs with root privileges, which is necessary to start the service. The tasks section of the playbook contains two tasks. The first task checks the status of the httpd service using the systemd module. If the service is not started, the state parameter sets the service to started. The enabled parameter ensures that the service will start automatically when the system boots up. The register parameter stores the result of this task in a variable called service_status. The second task starts the httpd service using the systemd module, but only if the service_status.changed variable from the first task shows that the service was not already started. The when parameter specifies this condition. The loop_control parameter adds a label to the loop, which will be used to identify the server where the https service is being started.
