In OpenBSD, there's no logrotate in ports, and newsyslog seems to have limited features as far as monthly rotation of a huge number of log files is concerned.

I have a lot of domains, a huge number of nginx log-files names like /var/www/logs/*/*.{access,error}.log.

I'm thinking a small shell script and cronjob. What would be the easiest way to rotate them all monthly, and append the prior month to the filename?

  • could you elaborate on the limited features of newsyslog? Also this question should be in serverfault IMO. – ramrunner Mar 03 '13 at 12:11

    `newsyslog` doesn't let you postfix the date into the filename of the rotated files (`….access.log.2013-02`), and it also does not support wildcards. This question deals with shell tricks (renaming files through shell), so I think stackoverflow is a more appropriate venue than serverfault. – cnst Mar 03 '13 at 20:35

I think the following crontab should work:

0   0   1   *   *   /etc/nginx/logrotate.monthly.sh

Where /etc/nginx/logrotate.monthly.sh should have the following content:

find /var/www/logs/ -name "*log" -exec \
mv -i {} {}.`sh -c 'date -r $(expr $(date +%s) - 1209600) +%Y-%m'` \; ; \
kill -USR1 `cat /var/run/nginx.pid`

The -i/--interactive ("prompt before overwrite") option to mv is important to ensure that files don't get overwritten. We get the date for the filename by moving today's date two weeks back (as per « tcsh: print date 2 weeks ago in shell »).

As documented, "NGINX will re-open its logs in response to the USR1 signal."

please check also this misc@ thread.

(also keep in mind the caveat documented in the FAQ about privseped apache and the need for a small time window upon the move.)

  • the misc@ thread does not address the issue with several dozen `/var/www/logs/…/….access.log` files for different domains – cnst Mar 03 '13 at 20:38
