脚本说明：

每天00:00定时切割Nginx日志

[root@check1 ~]# cat /etc/crontab SHELL=/bin/bashPATH=/sbin:/bin:/usr/sbin:/usr/binMAILTO=rootHOME=/# For details see man 4 crontabs# Example of job definition:# .---------------- minute (0 - 59)# | .------------- hour (0 - 23)# | | .---------- day of month (1 - 31)# | | | .------- month (1 - 12) OR jan,feb,mar,apr ...# | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat# | | | | |# * * * * * user-name command to be executed00 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:1.0LOGS_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 $LOGS_PATH/old_accessfiif [ ! -d "$LOGS_PATH/old_error" ]then    mkdir $LOGS_PATH/old_errorfimv ${LOGS_PATH}/access.log ${LOGS_PATH}/old_access/ACCESS_${YESTERDAY}.logmv ${LOGS_PATH}/error.log ${LOGS_PATH}/old_error/ERROR_${YESTERDAY}.logkill -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    donefi
