Systemd serves as the default system and service manager for Linux distributions, including Red Hat Enterprise Linux (RHEL), replacing the traditional Init systems. It efficiently manages system startup, service control, and resource allocation, providing advanced features such as parallel service startup, dependency handling, and resource management. As a core component of modern RHEL environments, Systemd enhances overall system performance and flexibility.
Cron is a job scheduler in Unix-like operating systems which is managed by systemd service. It facilitates the automation of scripts, commands, and programs at predefined intervals, usually employed for routine tasks such as system maintenance, backups, and regular updates.
The session will offer a comprehensive overview of Systemd, exploring its key features and technical advantages over legacy systems. In addition, we’ll delve into Cron’s scheduling capabilities, examine its syntax, and practical use cases.
Furthermore, the webinar will also address frequently asked questions related to support cases involving Systemd and Cron. This segment will provide valuable guidance on resolving typical challenges and offer best practices for maintaining and optimizing these services in the RHEL environment.
The following topics will be covered in this webinar:
- Overview of Init & Evolution to Systemd
- Key features & Architecture of Systemd & Systemd Units
- Control Groups (cgroups) & Systemd for Resource Management
- Task Scheduling with Cron service or Systemd timer
- Frequently Encountered Support Issues and Solutions related to Systemd and Cron
