systemctl - a hands-on Linux lab on a real virtual machine.
The RHCSA deploy-configure capstone on a real RHEL 10 machine. Commission a fresh server: a nightly cron job, a service enabled and started, a dnf repository, the timezone set, and a persistent kernel argument, graded on live end-state. Mission mode.
You have finished the Deploy, Configure, and Maintain module. Now you commission a fresh RHEL 10 server the way an engineer does on day one: schedule a nightly job, bring a service up and make it stay up, wire in a package repository, fix the clock, and set a boot-time kernel option. Every piece is graded on the live result, exactly like the exam.
Five objectives, one real machine. Everything you set must survive a reboot.
This is mission mode. No commands are shown. You read the objective, recall the tool, and configure the machine. You will need root, so reach for sudo. Progress checks itself against the live system.
One quick rep before you start. Before you change any service, you look at what state a service is in. Ask whether the time service, chronyd, is enabled to start at boot.
prompt: [root@servera ~]# answer: systemctl is-enabled chronyd output: enabled hint: is-enabled gives the one-word boot answer for a service: systemctl is-enabled chronyd
That one word, enabled or disabled, is the scriptable truth about boot state. is-active is its partner for right-now state. You will lean on both to commission this server. Now roll it out.
Boot the machine below and take the console. Read ~/ROLLOUT.txt for the checklist. Five objectives: a daily cron job for student, the rollout-agent service both enabled and started, a labrepo dnf repository with GPG checking off, the timezone set to America/New_York, and the kernel argument quiet added persistently. Work as root, and make every change stick across a reboot.
Practice Mission Control: Operation Rollout in a real Linux terminal at The Linux Camp. Progress is verified automatically as you type commands on the machine.
