How to configure log4j to only keep log files for the last seven days?

Viewed 171721

I have the following logging problem with several Java applications using log4j for logging:

I want log files to be rotated daily, like

log.2010-09-10
log.2010-09-09
log.2010-09-08
log.2010-09-07
log.2010-09-06
log.2010-09-05
log.2010-09-04

But for data security reasons we are not allowed to keep log files for longer than seven days at my company. So the generation of the next next log file log.2010-09-11 should trigger the deletion of log.2010-09-04. Is it possible to configure such a behaviour with log4j? If not, do you know another elegant solution for this kind of logging problem?

My script based on @dogbane's answer

/etc/cron.daily/hbase

#!/bin/sh
find /var/log/hbase -type f -name "phoenix-hbase-server.log.[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]" -exec bzip2 {} ";"
find /var/log/hbase -type f -regex ".*.out.[0-9][0-9]?" -exec bzip2 {} ";"
find /var/log/hbase -type f -mtime +7 -name "*.bz2" -exec rm -f {} ";"

/etc/cron.daily/tomcat

#!/bin/sh
find /opt/tomcat/log/ -type f -mtime +1 -name "*.[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9].*log" -exec bzip2 {} ";"
find /opt/tomcat/log/ -type f -mtime +1 -name "*.[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9].txt" -exec bzip2 {} ";"
find /opt/tomcat/log/ -type f -mtime +7 -name "*.bz2" -exec rm -f {} ";"

because Tomcat rotate needs one day delay.
