问题
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?
回答1:
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 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 »).

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.)
