Linux System Management: Manage Linux Services

Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

To start the lab, you'll familiarize yourself with the systemctl command and how to use it to manage services on Linux systems. You'll apply systemctl along with various subcommands to enable, disable, start, and observe the status of the chrony service.

In this challenge, you will use commands from the systemd ecosystem to update the server’s hostname, time zone, and locale.

You’ll deploy a unit file for a custom service. Then you’ll enable service and check the service status.

Managing scheduled tasks is important, and you will use crontab, at, and systemctl commands to do so.

Now, you will use the ps, pstree, pgrep, and pkill commands to view and manage processes on the server.

You earlier practiced with process, and will now delve into this further, starting with the top command to observe the processes running on the system. Then, you will use the nice and renice commands to change the priority of processes.

Welcome to the final challenge! This is your last chance to experiment in the environment. Clicking Finish Lab will end this little world that flittered into existence just for you.
