Start and Kill Running Process
Learn how to start and terminate processes on a remote hosts using Ansible. Also how to execute tasks to initiate a process and then kill it from the control node, providing a practical understanding of remote process management.
About This Lab
This hands-on lab will teach you how to start and terminate running processes on remote hosts using Ansible. Ansible is a powerful automation tool that allows you to manage and orchestrate tasks across multiple remote systems. In this lab, you'll learn how to initiate a process, find its process ID, and terminate it all remotely from the control node, providing you with a practical understanding of remote process management.
What You Will Learn
This lab will guide you through:
- Starting a process on a remote host using Ansible.
- Finding the process ID of a running process on a remote host.
- Terminating a process on a remote host using Ansible.
- Using Ansible playbooks to automate process management tasks.
- Verifying that processes are correctly started and killed remotely.
Why Learn Remote Process Management with Ansible?
Remote process management is an essential skill for system administrators, especially when managing multiple systems or servers. Automating these tasks with Ansible improves efficiency and consistency. Understanding how to start and stop processes remotely is valuable for troubleshooting, maintenance, and ensuring system stability across large environments, such as production servers or cloud infrastructures.
Who Should Take This Lab?
This lab is ideal for:
- System administrators looking to automate process management across remote hosts.
- Students preparing for certifications like Red Hat Certified Engineer (RHCE).
- DevOps professionals and anyone interested in automating system administration tasks using Ansible.
Prerequisites
Before starting this lab, ensure you have:
- Basic knowledge of Linux system administration and process management.
- Familiarity with using the command-line interface and SSH.
Lab Highlights
Key steps you will perform in this lab include:
- Mapping remote host IP to a hostname for easier management.
- Starting a process (e.g., `sleep 1000`) on a remote host using an Ansible playbook.
- Finding the process ID of a running process and verifying it with `ps` commands.
- Creating a playbook to terminate a running process remotely using Ansible.
- Verifying that the process is successfully killed on the remote host.
This lab provides foundational skills for automating process management tasks with Ansible, helping you to work more efficiently in managing systems remotely.
