Lab 4

Goals

• Setup a cron job
• Setup a service
• Answer questions about cron/systemctl

Setup CRON

Edit the crontab to append the current date to a file in the grader's home directory called date.txt every 5 mins.

Setup a service

Install Node Exporter [1], which will be good practice for getting Prometheus working in a future assignment.

Setup Node Exporter Service

Create a systemd service file for node exporter at /etc/systemd/system/node_exporter.service

Answer Questions about Cron/systemctl

Answer the following questions in the A4_README.md file on your GitHub branch.

1. What is cron?
2. What is systemctl?
3. Why might you want to use cron over systemctl?
4. When might you want not to use either?
5. Why are both important if you are administrating a machine?

Submitting Assignment

So make sure you do the following:

For testing your VM:

• Submit the IP of your VM instance to https://inginious.csuchico.edu for the Lab 4 submission.
• The submission will only count for 50% of the assignment credit, so you won't see higher than a 50 on INGInious, the rest of the score comes from the questions

Commit these to your course GitHub repo on the assignment4 branch. * A4_README.md

Verify that you can see your files on GitHub for the repo under the *assignment4& branch. Also, make sure your branch is named correctly, or it will not be pulled for grading.
