Squid 默认的5天会压缩一次, 在 /etc/logrotate.d/squid中有设置。如果你修改了日志的位置,

　　请修改 /etc/logrotate.d/squid

　　/home/log/squid/access.log {

　　weekly

　　rotate 5

　　copytruncate

　　compress

　　notifempty

　　missingok

　　}

　　/home/log/squid/cache.log {

　　weekly

　　rotate 5

　　copytruncate

　　compress

　　notifempty

　　missingok

　　}

　　/home/log/squid/store.log {

　　weekly

　　rotate 5

　　copytruncate

　　compress

　　notifempty

　　missingok

　　# 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

　　}

　　首先修改squid.conf

　　logfile_rotate 3(保留几份日志)

　　修改/etc/crontab

　　0 0 * * * squid /home/squid/sbin/squid -k rotate

　　(每天压缩一次)

　　crontab /etc/crontab (crontab生效)
