vim /etc/logrotate.conf

# see "man logrotate" for details
# rotate log files weekly
weekly

# keep 4 weeks worth of backlogs
rotate 4

# create new (empty) log files after rotating old ones
create

# use date as a suffix of the rotated file
dateext

# uncomment this if you want your log files compressed
#compress

# RPM packages drop log rotation information into this directory
include /etc/logrotate.d

# no packages own wtmp and btmp -- we'll rotate them here
/var/log/wtmp {
    monthly
    create 0664 root utmp
    minsize 1M
    rotate 99
}

/var/log/btmp {
    missingok
    monthly
    create 0600 root utmp
    rotate 99
}

# system-specific logs may be also be configured here.

vim /etc/logrotate.d/nginx

/var/log/nginx/*.log {
        daily
        missingok
        rotate 52
        compress
        delaycompress
        notifempty
        create 640 nginx adm
        sharedscripts
        postrotate
                [ -f /var/run/nginx.pid ] && kill -USR1 `cat /var/run/nginx.pid`
        endscript
}

vim /etc/logrotate.d/tomcat

/data/chexian-manage/logs/*.log{
rotate 15
daily
copytruncate
compress
notifempty
missingok
}

其中：
rotate 7 表示保留7天的备份文件
daily 表示每天整理一次
copytruncate 表示先复制log文件的内容，然后再清空
compress 表示压缩备分文件
missingok 表示如果找不到log文件也没OK
notifempty 表示如果log文件是空的，就不进行rotate
