Logrotate in /etc/cron.daily

SUSE Linux Enterprise Server SLES Configure-Administer
1

Hello everyone,

after upgrading from SLES12 SP2 to SP3 the logrotation from /etc/logroate.d/ via cronjob doesn’t working anymore.
So I found out, that the logrotate-file in /etc/cron.daily/ has gone away.

Is this a feature or a bug? :confused:

Is there a new way to rotate the logs?

Best Regards
Christian

Hi
A feature… things moving to systemd…

systemctl status logrotate.service

You should see;

Process: [PID] ExecStart=/usr/sbin/logrotate /etc/logrotate.conf (code=exited, status=0/SUCCESS)

Thanks for your answer.

So, logrotate.servcice is deactivated.
If I activate it, when will the logrotate-command execute?

Hi
Yes it will, you can check the time it last ran from the status output, eg;

systemctl status logrotate.service 

● logrotate.service - Rotate log files
   Loaded: loaded (/usr/lib/systemd/system/logrotate.service; static; vendor preset: disabled)
   Active: inactive (dead) since Fri 2017-10-06 06:03:04 CDT; 5min ago

systemctl start logrotate.service

systemctl status logrotate.service 

● logrotate.service - Rotate log files
   Loaded: loaded (/usr/lib/systemd/system/logrotate.service; static; vendor preset: disabled)
   Active: inactive (dead) since Fri 2017-10-06 07:04:21 CDT; 7s ago

Hi
But it is done automatically by systemd timers, no need for a cron job?

Hi
Hmmm, look in /usr/lib/systemd/system/ the file logrotate.timer should be there, if not force the re-install of logrotate and check again and for the softlink down in /etc/systemd/system/timers.target.wants/

Else manually create the link;

ln -s /usr/lib/systemd/system/logrotate.timer /etc/systemd/system/timers.target.wants/logrotate.timer
systemctl daemon-reload

The timer has to be enabled. This creates the link!

/root>systemctl enable logrotate.timer 
Created symlink from /etc/systemd/system/timers.target.wants/logrotate.timer to /usr/lib/systemd/system/logrotate.timer.

After enabling the timer, the link exists.

OnCalendar=daily AccuracySec=12h

means logrotation everyday at 12:00 and 24:00?

13

Hi
I would imagine it’s daily from last boot time…

systemctl status logrotate.timer
● logrotate.timer - Daily rotation of log files
Loaded: loaded (/usr/lib/systemd/system/logrotate.timer; enabled;

I want to logrotate the apache2 logfiles, daily at 24:00.
How can I do that with the systemd logrotate?

[QUOTE=christianmolecki;39928]I want to logrotate the apache2 logfiles, daily at 24:00.

Hi
I would look at disabling the timer and then copy /usr/lib/systemd/system/logrotate.timer to /etc/systemd/system/ then edit OnCalander to equal --* 00:00:00 and enable/start/status the service, it should be pointing at your timer service and not the systemd one.

If you look at man systemd.time at the end there are lots of configuration options, eg add UTC if your wanting it to be at 00:00:00 UTC

16

Hello,

systemctl enable logrotate.service systemctl enable logrotate.timer systemctl start logrotate.timer

Now, the logrotate will execute on 24:00/00:00.

Thanks for your help!
