What's the easiest way to rotate nginx log files monthly?
I think the following crontab should work:
0 0 1 * * /etc/nginx/logrotate.monthly.shWhere /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.)
