Day 6: Create a Cron Job

← Back to Index | ← Previous: Day 2

Objective

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. Therefore, perform the steps below:

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

Steps

1. Login into each server using ssh
2. Install cronie package:

   sudo yum install cronie -y

3. Enable and start crond service:

   sudo systemctl enable crond
   sudo systemctl start crond

   Verify the service is running:

   sudo systemctl status crond

4. Add the cron job for root user:

   echo "*/5 * * * * echo hello > /tmp/cron_text" | sudo crontab -

5. Verify the cron job is added:

   sudo crontab -l
