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:
a. Install cronie package on all Nautilus app servers and start crond service.
b. Add a cron */5 * * * * echo hello > /tmp/cron_text for root user.
Apply this solution to all app servers
# ssh into remote server
ssh <user>@<server.ip>
# check if cronie is running
sudo systemctl status cronie
# install it if it is not running
sudo yum install cronie
# check crond status
sudo systemctl status crond
# start crond service
sudo systemctl start crond
# confirm it is running
sudo systemctl status crond
# run this to create and register a cron job
sudo crontab -e
# view cron job
sudo crontab -l
# view cron jobs by the root user
sudo crontab -u root -l
