[CentOS] Slightly OT: Cron for Logrotate and Squid
Howdy list, Hey does anyone know what the best cron job is to call logrotate to run the squid logrotations? -Or the subscribe address for a squid or logrotate mailing list (can't seem to find anything other than the usual MARC archives). I have this in /etc/logrotate.conf # rotate log files daily, they get too big otherwise, another story. daily # keep 8 weeks worth of backlogs e.g. 60 days rotate 8 # create new (empty) log files after rotating old ones create # No way, don't compress on a busy cache box, too much load. #compress # Rotate logs for specific daemons here: include /etc/logrotate.d ############################################## I have this in /etc/logrotate.d/squid /var/log/squid/access.log { daily rotate 60 copytruncate #compress notifempty missingok # same for the other two squid logs # This script asks squid to rotate its logs on its own. # Restarting squid is a long process and it is not worth # doing it just to rotate logs postrotate /usr/sbin/squid -k rotate endscript } ################################################ and it's been suggested to do this in Cron, but it *does not* look right and is the part i'm most concerned about, I drew it slightly out of context from here: http://www.tldp.org/HOWTO/Bandwidth-Limiting-HOWTO/faq.html It's the rm -f statement I worry about. #SQUID - logrotate 01 4 * * * root /opt/squid/bin/squid -k rotate; /usr/sbin/logrotate /etc/logrotate.conf; /bin/rm -f /var/log/squid/*.log.0 #################################################################### Basically don't want to restart the squid daemon on my cache servers because it's just too too nasty of a proposition. Any suggestions for the proper way to call logrotate from Cron with regard to squid in particular? -karl
