I've set you up to rotate daily, but you don't.

But when I do it manually, it does work.

logrotate -vf /etc/logrotate.conf

This is my log file to rotate. /mylogs/log (-rwxrwxrwxrwx 1 admin admin)

This is the system configuration.

/etc/logrotate.conf (-rw-r--r-- 1 root root):

/mylogs/log {
create 0640 root utmp
missingok
daily
copytruncate
rotate 10
dateext
}

/etc/logrotate.d/syslog (-rw-r--r-- 1 root root):

/var/log/cron
/var/log/maillog
/var/log/messages
/var/log/secure
/var/log/spooler
{
missingok
sharedscripts
postrotate
/bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || 
true
endscript
}

/etc/cron.daily/logrotate (-rwx------ 1 root root):

#!/bin/sh

/usr/sbin/logrotate -s /var/lib/logrotate/logrotate.status /etc/logrotate.conf
EXITVALUE=$?
if [ $EXITVALUE != 0 ]; then
/usr/bin/logger -t logrotate "ALERT exited abnormally with 
[$EXITVALUE]"
fi
exit 0

/etc/crontab (-rw-r--r--. 1 root root):

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root

# For details see man 4 crontabs

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR 
sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed

Additional information. CentOS operating system

How can I get it to rotate properly.

UPDATE

I think the problem is in assigning owner, group and permissions of 3 things. The /mylogs/ folder (root root) The /mylogs/log file (admin admin)
The create option of logrotate.conf (create 0640 root utmp)

Someone with logrotate running correctly. Please let me know how you have assigned the previous 3 values. the folder - the file - the create config in logrotate.conf

  • Can you provide information how do you "run manually"? At the moment I can see you have different file ownership in different places.

  • Hi, thanks for the comment, I added the line that I run manually.

  • Did you look at your logfiles, you should see some cron activity telling you it executes logrotate each day.

  • Sorry but I don't know how to check what you tell me, I'll see if I can get the information to do it.

Join two strings here

/usr/sbin/logrotate -s /var/lib/logrotate/logrotate.status 
/etc/logrotate.conf

To one string like this one:

/usr/sbin/logrotate -s /var/lib/logrotate/logrotate.status /etc/logrotate.conf

Or put backslash after first string, like this:

/usr/sbin/logrotate -s /var/lib/logrotate/logrotate.status \
/etc/logrotate.conf

p.s. there is an excellent option -x for /bin/sh to make debug output from shell, and I guess you'll be able to find this mistype next time if you'd try to run /bin/sh -x /etc/cron.daily/logrotate

  • ok. @xav So next guess: is there /var/lib/logrotate/logrotate.status file and folder for it: /var/lib/logrotate/ ? Logrotate may skip rotating logs if there is no such folder. And also there may be some notes about errors on state file. Please check it for any warnings.

  • Hello, the folder and file exist. There are no warnings or error messages inside. /var/lib/logrotate/logrotate.status (-rw-rw-r-- 1 admin admin)

  • @xav are there any records about your /mylogs files in status file? You have -s /var/lib/logrotate/status on your cron file and by hands you run without it, this also may affect the way file is rotated. You also could use -d flag for logrotate to show what it will do without actual rotating and compare -d outputs for -s /var/lib/logrotate/status and without -s runs.

after several tests I managed to get it to rotate correctly again.

To do this, I have assigned the user (root) and group (root) of the log file.

Also change your permissions to 666.

With respect to the folder containing the file, it is assigned a user (root) of group (root) and 755 permissions.

Finally within the configuration of logrotate.conf the configuration assigned to this property 'create' was user (root), group (utmp) and permissions (644)

I hope this information will be useful in case someone has a similar problem.

Greetings and thank you.

    You should not have permissions 666, instead you should use 644. With the 'w' flag as "other" (the 006 represents ------rw-) which means anyone on that computer can temper with your file.
