Specify the time of daily log rotate

I noticed that daily log rotations which are listed under /etc/logrotate.d/ are executed in the morning around 6:40 am. This is clear from the beginning and ending of the log files. Can I customize this time and set it to midnight for example?

It is nice to have one log file per day.

I am using ubuntu server 10.04 if that matters.

Solution 1:

Edit in /etc/crontab the line that says

25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )

so that the 25 6 reads 0 0. This will make it so that all scripts in /etc/cron.daily runs at midnight.

If you only want to make logrotate run at midnight, move /etc/cron.daily/logrotate to some other directory, and add the line

0 0    * * *   root    /new/path/to/logrotate/script

at the end of /etc/crontab.

Solution 2:

If you have Webmin/Virtualmin installed on your server you can change your logrotate execution time easier:

Just go to Webmin -> Scheduled Cron Jobs and Select daily cron. Modify it as you want and save it.
