Cron service allows you to run scheduled tasks in linux/unix.
It turns out that the service is not automatically turned on in Fedora core 17.
[root@fortis log]# less /val/log/cron.log
/val/log/cron.log: No such file or directory
no log file -> so it's not working
[root@fortis log]# ps aux | grep -i cron | grep -v grep
cron not found in the memory -> so it's not working
[root@fortis log]# service crond status
Redirecting to /bin/systemctl status crond.service
crond.service - Command Scheduler
Loaded: loaded (/usr/lib/systemd/system/crond.service; enabled)
Active: inactive (dead)
CGroup: name=systemd:/system/crond.service
status is inactive: that definitely means that it's not enabled.
Enable cron
[root@fortis log]# chkconfig crond on
Note: Forwarding request to 'systemctl enable crond.service'.
Start the cron service
[root@fortis log]# service crond start
Redirecting to /bin/systemctl start crond.service
Check status just in case
[root@fortis log]# service crond status
Redirecting to /bin/systemctl status crond.service
crond.service - Command Scheduler
Loaded: loaded (/usr/lib/systemd/system/crond.service; enabled)
Active: active (running) since Thu, 06 Jun 2013 02:31:56 +0000; 6s ago
Main PID: 3339 (crond)
CGroup: name=systemd:/system/crond.service
â 3339 /usr/sbin/crond -n
OK. It works.
