Cron Not Working on CentOS
 
I've got a LAMP server running CentOS 5.7 & noticed a script I had in /etc/cron.hourly wasn't being ran. I checked /var/log/cron and it's completely empty:

Code:
[root@lamp]# ls -la /var/log/cron
-rw------- 1 root root 0 Jun 23 2010 /var/log/cron
So I don't think I have the correct packages installed for cron.

I searched my systems for all installed packages with the name "cron" in it:

Code:
[root@lamp:~]# rpm -qa | grep -i "cron"
crontabs-1.10-8
That's all that came up. Am I missing something? There's no startup / shutdown scripts in /etc/init.d/ either. Any ideas what I'm missing?

crontabs is the only file you need.

Try running crontab -l

if it doesn't come up than it didn't get saved -- I reccommend using
Code:
crontab -e

0**** /path/command

Remember:

I'm very confused...

I have the package 'crontabs' installed:

Code:
[root@lamp:~]# rpm -qa | grep -i "crontabs"
crontabs-1.10-8
But when I try and list / edit crontabs, I get the following:

Code:
[root@lamp:~]# crontab -l
-bash: crontab: command not found

Is the cron daemon running?

Code:
# pgrep crond
If not:
  1. Is it installed? You're looking for the vixie-cron package.
  2. Is the service started? (/etc/init.d/crond)

Just noticed this. There's nothing in /etc/init.d at all? (You're certainly missing something, if correct.)

You don't have the cron daemon.

[root@server] yum install vixie-cron

Will fix you up.

OK so I ran the command to install the package you suggested:

Code:
[root@lamp:~]# yum install vixie-cron

Running Transaction
  Installing    : vixie-cron                                                                                                                                                            1/1

Installed:
  vixie-cron.x86_64 4:4.1-77.el5_4.1
Now I can see the startup / shutdown script in /etc/init.d/

Code:
[root@lamp:~]# /etc/init.d/crond start
Starting crond:                                            [  OK  ]
Now how can I verify that the script '00awstats' that is stored in the /etc/cron.hourly/ directory is properly ran? Is there a way I can verify the script is running?

How about just 'grep 00awstats /var/log/cron'?
