Interestingly, the log rotation utility rotatelogs which came with Apache does not work with Ubuntu 7.04 installation. At least not when the Apache is installed via apt-get.
By default, Ubuntu server utilizes logrotate not rotatelogs to rotate all its server logs. Appache access and error logs are rotated on a weekly basis when first installed. To change the log rotation frequency, you will need to change the following file:
/etc/logrotate.d/apache
The main difference between logrotate and rotatelogs is that logrotate is triggered by a cron job whereas rotatelogs runs in the background as a daemon. In Ubuntu, cron jobs are neatly organized into cron.hourly, cron.daily, cron.weekly and cron.monthly folders. This makes creating ad-hoc cron jobs a very easy task.
