logrotate 是linux系統自帶的日誌分割與壓縮程序，通過crontab每日運行一次。
$ cat /etc/cron.daily/logrotate #!/bin/sh test -x /usr/sbin/logrotate || exit 0 /usr/sbin/logrotate /etc/logrotate.conf
$ cat /etc/logrotate.conf
# see "man logrotate" for details
# rotate log files weekly

# keep 4 weeks worth of backlogs
rotate 4
# create new (empty) log files after rotating old ones

# uncomment this if you want your log files compressed
#compress
# packages drop log rotation information into this directory
include /etc/logrotate.d
# no packages own wtmp, or btmp -- we'll rotate them here
