RE: Troubles with cron

Have you looked at all the "standard" cron pitfalls? The default PATH
(and other environment variables) is not the same as being logged in as
a given user. This is the typical cause of scripts "not working" from
cron...

Subject: Troubles with cron

Greetings,

I'm having voodoo trouble with cron on my webserver. In a nutshell, cron

is running and the scheduled jobs are logging with no errors; but those 
scheduled commands aren't actually working. Red Hat Enterprise Linux WS 
(v. 3 for AMD64/Intel EM64T)

1. To start troubleshooting I took out all five of my cron jobs and 
picked 2 simple ones to test with.
2. I verified that they ran from the bash shell as root.
3. Attempted to run them every minute individually as scheduled jobs to 
no avail.
4. I then made shell scripts to run them, verified that the shell 
scripts ran and worked as root, and scheduled them with cron as above to

no avail.
5. I then tried putting the aforementioned shell scripts 
in/etc/cron.hourly. Again, the script appears to run normally, but there

is no evidence that it actually worked.

Last night I left in one command that was scheduled to run hourly. I put

the same command in a shell script and placed it in /etc/cron.hourly It 
updates our users webalizer pages with current apache access logs.

Here is the file listing so you can see the permissions and owernership.
drwxr-xr-x 2 root root 4096 Nov 14 17:08 .
drwxr-xr-x 67 root root 8192 Nov 15 05:37 ..
-rwxr-xr-x 1 root root 69 Nov 14 17:08 webalizer.sh
[root@circle cron.hourly]#

Here is the cron log output for last night. As always the script did not

update the webalizer pages as it does when ran manually.

Nov 15 05:38:31 circle crond[1824]: (CRON) STARTUP (V5.0)
Nov 15 05:55:01 circle crond[2132]: (root) CMD (for i in 
/etc/webalizer/*.conf; do webalizer -c $i; done)
Nov 15 06:01:01 circle crond[2170]: (root) CMD (run-parts
/etc/cron.hourly)
Nov 15 06:55:02 circle crond[2519]: (root) CMD (for i in

Nov 15 07:55:01 circle crond[2974]: (root) CMD (for i in 
/etc/webalizer/*.conf; do webalizer -c $i; done)
Nov 15 08:01:01 circle crond[3021]: (root) CMD (run-parts
/etc/cron.hourly)
Nov 15 08:55:01 circle crond[3824]: (root) CMD (for i in 
/etc/webalizer/*.conf; do webalizer -c $i; done)
Nov 15 09:01:01 circle crond[3869]: (root) CMD (run-parts
/etc/cron.hourly)

Ive searched online for an answer and came up empty handed. Any help 
would be greatly appreciated.

Kind regards,

Jesse
