[root@localhost ~]# crontab -l
-bash: crontab: command not found
Problem or Goal:
To be able to schedule jobs/tasks using crontab on Fedora.
For example scheduling the cacti poller script to run every 5 mins
*/5 * * * * root /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1
Cause:
Crontab is not installed by default on Fedora
Solution:
1. Fedora uses with the following automated task utilities:
- cron
- anacron
- at
- batch
2. To install Cron and Anacron, run the following command:
[root@localhost cacti]# dnf install cronie cronie-anacron
3. Start the crond service
[root@localhost cacti]# systemctl start crond
Problem Solved?
Yes
[root@localhost cacti]# crontab -l
no crontab for root
Use "crontab -e" command below to add your jobs/tasks
[root@localhost cacti]# crontab -e
for example the cacti poller job has been added
[root@localhost cacti]# crontab -l
*/5 * * * * root /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1
