In this lesson
Prepare for the Linux+ XK0-006 exam (CompTIA Linux+ V8). In this lesson: unit files and overrides, systemctl (start, stop, reload, enable, mask, status), timers and mount units, targets, boot time with systemd-analyze, hostnames and time with hostnamectl and timedatectl, and kernel parameters with sysctl, with Pinecrest Media, a fictional video streaming company, as the running example. Includes three original practice questions.
Preview the topics
- An old FTP service must never run again on a storage server, even if another unit asks for it, but the package must stay installed for now. What should the admin run?
- A thumbnail cleanup runs from a systemd timer at 3 a.m. When a server was off for maintenance at that time, the cleanup was skipped. Which setting makes it run at the next boot instead?
- A web server takes two minutes to boot, and the team wants to know which units are the slowest to start. Which command shows that?
