Labs

• RH134 Ch 1: Shell Scripts for Daily Admin — The WebAsha helpdesk repeats the same commands every morning. Turn them into small Bash scripts: a system summary, a bulk user creator for new trainees, and a fix for a disk-check script a colleague left half working.
• RH134 Ch 2: at, cron and systemd Timers — WebAsha's training server needs housekeeping that runs on its own: a one-off reminder, a weekday disk report for the student account, a /tmp clean-up, a nightly report as a systemd timer, and a managed runtime directory.
• RH134 Ch 3: tuned Profiles and Process Priority — servera now runs the report generator for WebAsha's analytics team. Apply the right tuning profile, record what tuned recommends, and stop the batch jobs from stealing CPU from interactive users.
• RH134 Ch 4: Fix SELinux for a Web Server — A colleague set up the WebAsha documentation site on servera: Apache serves `/webdata` on port `8818`. It only worked because they switched SELinux to permissive "for now" and wrote that into the config. Put SELinux back into enforcing mode and make the site work the right way: labels, port type and booleans, all persistent.
• RH134 Ch 5: Partitions, File Systems and Swap — A new disk, `/dev/vdb`, has been added to servera for the training archive. Partition it with GPT, create XFS, ext4 and VFAT file systems plus some swap, and make every mount survive a reboot.
• RH134 Ch 6: Logical Volumes — The reporting database needs space that can grow. Build an LVM volume on a spare disk, mount it persistently, then grow it online when the team asks for more.
• RH134 Ch 6: Grow, Add and Remove Logical Volumes — The application log volume on servera is full and an old volume is no longer needed. Add a disk to the volume group, grow the logs online, add swap on LVM, retire the old volume, and build a new volume group to the developers' extent-size spec.
• RH134 Ch 7: NFS Mounts and the Automounter — serverb is the WebAsha file server. Mount the shared team area permanently, and use autofs so trainee home directories and the project documents appear on demand instead of being mounted all the time.
• RH134 Ch 8: Targets, GRUB and a Lost Root Password — servera came back from the data centre in a bad way: nobody knows the root password, it boots to the graphical target although it is a server, and someone left a stale entry in `/etc/fstab`. Fix the boot configuration, reset root's password at the console, and prove the machine reboots cleanly.
• RH134 Ch 9: firewalld Zones, Services and Rich Rules — servera is becoming WebAsha's intranet web server. Publish the site through firewalld, open the admin port, trust serverb, block a misbehaving host and tidy up a rule someone added only to the running configuration.
• RH134 Ch 10: Fix and Validate a Kickstart File — WebAsha is adding a third lab server, serverc, built unattended with kickstart. The draft file from the previous admin does not even validate. Fix it and complete it to the build sheet before it goes on the install server.
• RH134 Ch 11: Run Containers with Podman — WebAsha's documentation team wants its docs site in a container. Run it with a published port and a host directory, pass configuration through environment variables, make the site a systemd service that starts at boot, and give the student account its own rootless container.
• RH134 Ch 12: Image Mode (bootc) Build Files — WebAsha wants its intranet kiosks managed as images: the whole OS, web server included, is built like a container and rolled out with bootc. Prepare the build context in `/root/bootc` and the operator's runbook.
• RH134 Review: Part 2 Practice Exam — Exam-style practice: servera must be ready for a new WebAsha training batch. Work against the clock (45 minutes), with no hints if you can manage it. Everything must survive a reboot.
