💡 Hint

Common Mistakes

Using 'stop' instead of 'start' will turn the service off.

Using 'status' only shows the service state, it doesn't start it.

The 'start' command tells systemctl to start the specified service.

💡 Hint

Common Mistakes

Using 'enable' or 'disable' changes startup behavior, not current status.

Using 'restart' will stop and start the service, not just show status.

The 'status' command shows if the service is running or stopped.

💡 Hint

Common Mistakes

Using 'stop' stops the service now but does not disable auto-start.

Using 'start' or 'restart' will start the service, not disable it.

The 'disable' command stops the service from starting automatically at boot.

4fill in blank

Fill both blanks to create a command that restarts the docker service and shows its status.

Linux CLI

sudo systemctl [1] docker && systemctl [2] docker

Drag options to blanks, or click blank then click option'

Arestart

Cstatus

Dstop

Attempts:

💡 Hint

Common Mistakes

Using 'start' instead of 'restart' will not restart if already running.

Using 'stop' will stop the service, not restart it.

First, 'restart' restarts the service. Then, 'status' shows its current state.

Fill all three blanks to create a command that enables the nginx service, starts it, and then checks its status.

Linux CLI

sudo systemctl [1] nginx && sudo systemctl [2] nginx && systemctl [3] nginx

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'disable' instead of 'enable' will prevent auto-start.

Skipping 'start' means the service might not be running now.

Not checking 'status' leaves you unsure if the service started.

First, 'enable' sets the service to start at boot. Then, 'start' runs it now. Finally, 'status' shows if it is running.
