In linux is easy to rotate any logs and for apache in particular in this Ubuntu server we have:
$ cat /etc/logrotate.d/apache2 /var/log/apache2/*.log { weekly missingok rotate 52 compress delaycompress notifempty create 640 root adm sharedscripts postrotate /etc/init.d/apache2 reload > /dev/null endscript prerotate if [ -d /etc/logrotate.d/httpd-prerotate ]; then \ run-parts /etc/logrotate.d/httpd-prerotate; \ fi; \ endscript }This means every week the log will be gzipped and rotated, then recycled after number 52 is reached. However a week will be too much for a trace level. To correct this problem be sure mod-jk is configured to log as error then without disruption you can proceed as follows:
$ sudo vi /etc/logrotate.d/apache2 ... #replacing: #JkLogFile /var/log/apache2/mod-jk.log JkLogFile "|/usr/sbin/rotatelogs /var/log/apache2/mod-jk.log 86400" ... $ sudo mv /var/log/apache2/mod-jk.log /var/log/apache2/mod-jk.log.todelete $ sudo apachectl configtest $ sudo apachectl graceful $ sudo vi /etc/logrotate.d/apache2 ... #reverting: JkLogFile /var/log/apache2/mod-jk.log #JkLogFile "|/usr/sbin/rotatelogs /var/log/apache2/mod-jk.log 86400" ... $ sudo apachectl configtest $ sudo apachectl gracefulTake a look at how to avoid this issues through monit.
