6/100 Create a Cron Job

The Nautilus system admins team has prepared scripts to automate several day-to-day tasks. They want them to be deployed on all app servers in Stratos DC on a set schedule. Before that they need to test similar functionality with a sample cron job.

Tasks:
- Install cronie package on all Nautilus app servers and start crond service.
- Add a cron */5 * * * * echo hello > /tmp/cron_text for root user.

ssh tony@stapp01.stratos.xfusioncorp.com
sudo dnf install -y cronie

Complete!

sudo systemctl start crond
sudo systemctl status crond
● crond.service - Command Scheduler
     Loaded: loaded (/usr/lib/systemd/system/crond.service; enabled; preset: enabled)

sudo crontab -l
no crontab for root

sudo crontab -e
Copy and paste in:
*/5 * * * * echo hello > /tmp/cron_text

sudo crontab -l
*/5 * * * * echo hello > /tmp/cron_text

Repeat the same process for App 2 and App3
