脚本说明：
每天00:00定时切割Nginx日志


[root@check1 ~]# cat /etc/crontab 
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# * * * * * user-name command to be executed
00 00 * * * root /bin/bash /usr/local/nginx/conf/cut_nginx_log.sh

使用下面脚本，需根据实际路径进行修改
修改下面三项即可：
OLD_FILE中 +90代表保留90天的日志，90天后的会自动清理
LOGS_PATH
PID_PATH


#!/bin/bash
#CUT_NGINX_LOG
#Version:1.0
LOGS_PATH="/usr/local/nginx/logs"
YESTERDAY=`date -d "yesterday" +"%Y-%m-%d"`
PID_PATH="/usr/local/nginx/logs/nginx.pid"
OLD_FILE=`find $LOGS_PATH -mtime +90 -type f -name "ERROR*"`

if [ ! -d "$LOGS_PATH/old_access" ]
then
    mkdir $LOGS_PATH/old_access
fi
if [ ! -d "$LOGS_PATH/old_error" ]
then
    mkdir $LOGS_PATH/old_error
fi

mv ${LOGS_PATH}/access.log ${LOGS_PATH}/old_access/ACCESS_${YESTERDAY}.log
mv ${LOGS_PATH}/error.log ${LOGS_PATH}/old_error/ERROR_${YESTERDAY}.log

kill -USR1 `cat ${PID_PATH}`

if [[ ! -z $OLD_FILE ]]
then
    for a in $OLD_FILE
    do
        TIME=`date`
        echo "delet $a $TIME" >> /var/log/messages
        rm -rf $a
    done
fi
