In this chapter, you learned:
systemd provides a method for activating system resources, server daemons, and other processes, both at boot time and on a running system.
Use the systemctl to start, stop, reload, enable, and disable services.
Use the systemctl status command to determine the status of system daemons and network services started by systemd.
The systemctl list-dependencies command lists all service units upon which a specific service unit depends.
systemd can mask a service unit so that it does not run even to satisfy dependencies.
Click CREATE to build all of the virtual machines needed for the classroom lab environment. This may take several minutes to complete. Once created the environment can then be stopped and restarted to pause your experience.
If you DELETE your lab, you will remove all of the virtual machines in your classroom and lose all of your progress.
