How to enable logrotate

SUSE Linux Enterprise Server SLES Configure-Administer

Hi, my logrotate seems never working.

I have a few customized logrotate configuration, one of them:

cat /etc/logrotate.d/mongo.conf

/etc/logrotate.d/

/app/intellisurf/logs/mongodb/mongod.log {
compress
copytruncate
daily
dateext
rotate 7
size 50M

manual testing is fine (> sudo logrotate -f /etc/logrotate.d/mongo.conf)

if I checked /var/lib/logrotate.status, all are long time ago:

cat /var/lib/logrotate.status
logrotate state – version 2
“/var/log/iscsiuio.log” 2017-5-12-11:0:0
“/var/log/apache2/deflate.log” 2017-5-12-11:0:0

“/var/log/slpd.log” 2017-5-12-11:0:0
…

I didnot make any changes to default /etc/logrotate.conf：

cat /etc/logrotate.conf

see “man logrotate” for details

rotate log files weekly

weekly
…

I can see logrotate inside /etc/cron.daily:

ll /etc/cron.daily/

but I cannot see it in systemctl timer list and also cannot enable it (no such file or directory):

sudo systemctl list-timers -all

How to enable logrotate and verify it?

Thanks.

Presumably the above ends with a closing curly bracket (})?

This statement would suggest there is a closing curly bracket so it must
have been missed when pasting.

As recently posted in another recent logrotate thread[1] you need to
enable log rotation with “systemctl enable logrotate.timer” followed by
“systemctl start logrotate.timer”.

HTH.

Hi, actually i did try to do that, the problem is the logrotate.timer is missing from /etc/systemd/system/timers.target.wants. But thanks for answer, i just need to copy that file from somewhere.

Hi
The timer systemd service is in SP3, not SP2 it still uses the logrotate cronjob.

Do the other daily cron jobs run?

Have you configured the daily cron time via YaST /etc/sysconfig editor?

If you run the cronjob manually it runs?

Hi, malcolmlewis, you are right, the logrotate.timer is for SP3 not SP2, a temp cronjob is working.

ps -ef | grep cron

I did not set the time for cron.daily to start, /etc/sysconfig/cron:

At which time cron.daily should start. Default is 15 minutes after booting

the system. Example setting would be “14:00”.

Due to the fact that cron script runs only every 15 minutes,

it will only run on xx:00, xx:15, xx:30, xx:45, not at the accurate time

you set.

DAILY_TIME=“”

Thanks.

I did a test, and set DAILY_TIME=“12:10” and cron.daily seems being triggered:

ll /var/spool/cron/lastrun/

total 0
-rw-r–r-- 1 root root 0 Oct 17 12:15 cron.daily
-rw-r–r-- 1 root root 0 Oct 17 12:00 cron.hourly

-rw-r–r-- 1 root root 0 Oct 10 16:15 cron.weekly

but logrotate still seems not working:

Hi
Did you look at your config file and check the error user smflood indicated?

If you manually run;

/etc/cron.daily/logrotate

Any errors indicated?

8

Hi, there is no error but it does not work as expected:

sudo /etc/cron.daily/logrotate
compress_ext is /usr/bin/xz
compress_ext was changed to .xz

cat /etc/logrotate.d/mongo.conf

/etc/logrotate.d/

/app/intellisurf/logs/mongodb/mongod.log {
compress
copytruncate
daily
dateext
rotate 7
size 50M
}

ll /app/intellisurf/logs/mongodb
total 868
-rw-r–r-- 1 mongod mongod 22094 Oct 18 13:03 mongod.log
-rw-r–r-- 1 mongod mongod 862761 Sep 11 18:13 mongod.log.2017-09-11T10-13-00

btw, the logrotate problem happens on all machines with SuSE12 SP2.
