sridhar_dct3 · 05-10-2007, 02:40 AM

hi friends,

I have a problem in crontab. The crontab daemon is running fine . All the configurations are right. But the command was not executed . There is no log output in /var/log/cron
also . /var/log/cron file does not exist .

Then where is the log file . I am running as root user.

help me .

cat /var/run/crond.pid
3855

ps ax | grep -i cron
3855 ? Ss 0:00 /usr/sbin/cron
8853 pts/1 S+ 0:00 grep -i cron

# m h dom mon dow command
01 23 * * * /bin/tar -zcvf /tmp/file.tgz /root 1> /tmp/backup.log 2>/tmp/backup.err

Hi,

(Cron) Logging is done by the syslog daemon and configured in /etc/syslog.conf.

As root:

Make a backup before editing /etc/syslog.conf (cp /etc/syslog.conf /etc/syslog.conf.org). In case something goes wrong.

Add the following line: cron.* -/var/log/cron and restart the syslog daemon (from the /etc/rc.d/init.d directory, probably ./sysklogd restart, but this depends on your distro). You probably need to create the cron logfile (touch /var/log/cron) too before restarting the syslog daemon.

Hope this helps.

Also, if anything goes wrong you'll usually get an email in the root mail file.

in debian it is
# nano /etc/rsyslog.conf
and then
# /etc/init.d/rsyslog restart

Bonjour,

Petite question

Sous Ubuntu, faut-il modifier le fichier syslog.conf ou rsyslog.conf du coup ?

Merci !!
