Hello All,

I have to Rotate one of my log file (test_cron.log) which is under /root/ on daily basis , so for that i have made one new file in under /etc/logrotate.d/soc_logs.
also added entry in crontab as : */1 * * * * /usr/sbin/logrotate /etc/logrotate.d/soc_logs
But it does not rotate daily.
and write code as follows.

/root/test_cron.log
{
compress
daily
size 20k
rotate 7
dateext
create 0600 root root

}

Also i want 7 days backup of that log file and if file size increased by say for example 20k then also it must be make new file with date extension.

Thanks in advance..

Are you saying it doesn't check for rotation daily, or saying that you don't see the file rotated daily? The difference there is if you don't have the -f or --force option in your call to logrotate, then it won't force rotation and instead rely on the size qualifier of 20k. Have any of these files exceeded 20k prior to the daily call to logrotate and then not been rotated? Or have none of these files yet reached that size?

If you do invoke logrotate with the -f or --force option it will force rotation whether or not it feels rotation of a log file is required.

...additionally you can debug things and see for yourself running it as '/usr/sbin/logrotate -d /etc/logrotate.d/soc_logs;'. Do post the output if unsure.
*Ow, and there's no good reason to create and keep log files in the /root directory IMHO.

Excelling points. Right, not in /root. And you can manually run logrotate from the command line with the -d option as well as the -f option and see how it deals with your log file. That should assist you for when you're ready to let the cron job run it daily.

Generally, there is a file in /etc/cron.daily called logrotate that contains the "instructions" to run the program. You add your configuration file to the /etc/logrotate.d directory and you're done.

Double-check the permissions to the file you created, the permissions to the file you're attempting to run logrotate against, and verify that the size is large enough to trigger a rotate event.
