From logrotate manpage.

It will not modify a log more than once in one day unless the criterion for that log is based on the log's size

According to the man page, logrotate should rotate file if the configuration is based on logs size. But, my file is not getting even if the filesize if greater than 100k.

Can somebody point out what is the issue.

My configuration

/home/jetech/work/lampstack-5.3.9-0/apache2/logs/access_log  {
#    dateext
    rotate 365
    size 100k
    olddir /home/jetech/work/lampstack-5.3.9-0/apache2/old_logs

How do you know the file is not getting rotated?

On a Debian 6 Linode I have, in the default configuration logrotate was only scheduled by cron to run once per day, and at a very odd time at that. If only run once per day, naturally it'll only have one opportunity per day to look at the configuration, do the comparisons and perform the rotations required.

So, are you sure you're actually running your logrotate? Might want to check your /etc/cron* and /etc/cron*/* to see when and how often logrotate is scheduled to run.

For example, if logrotate script is present in /etc/cron.daily, then you may want to move it to /etc/cron.hourly, or, if hourly is not good enough, create a file in /etc/cron.d/ with the following content, to run logrotate every 10 minutes:

*/10  *  *  *  *   root    /usr/sbin/logrotate /etc/logrotate.conf

So logrotate actually works like this,

  • In the configuration we specify a running frequency (daily, hourly, monthtly)
  • There is an entry in /etc/cron.xxx for logrotate to execute.
  • logrotate runs via crontab

if you mentioned daily, everyday at the specified amount of time (/etc/crontab), the crontab process will run logrotate process for rotation. So, file size limit will not work as the process will never run.
