nginx日志文件按日期分割脚本 {card-describe title="写在开头"}工作环境下，更建议直接使用系统自带的日志切割工具lograte来进行日志分割。此脚本只为练习用。{/card-describe}{dotted startColor="#ff6c6c" endColor="#1989fa"/}1.若日志文件可能存在往日的访问信息，可以运行下面的脚本.该脚本先判断日志文件中是否存在过往的访问信息，如果存在，先处理这些过往信息。处理方式是按照日期生成文本文档，并写入对应的访问信息。然后清空日志文件，等待新的记录写入。如果不存在过往访问记录，则直接将该文件按日期重命名，然后通知nginx重新打开日志文件。说明：如果原始的日志文件非常大，可以先用split命令对文件进行切割，然后再逐个处理切割出来的小文件，以减轻服务器的压力。#!/bin/bash #将日志文件中未按日期分割的历史记录进行分割。 #获取日志文件中的日期信息，并将其写入临时文件 log_dir=/opt/access.log awk '{print $4}' $log_dir | awk -F: '{print $1}' | sed 's/\[//' | sort -u -t/ -k3 -k1 > /opt/log_date.txt #先判断日志文件中是否存在往期的日志信息，如果存在，先处理历史日志信息。 sum=`wc -l < /opt/log_date.txt` if [ $sum -gt 1 ];then #通过for循环，将历史日志记录按日期分别记录到指定的文件内。 for i in `cat /opt/log_date.txt` do dir=`echo $i| sed 's#/#-#g' ` grep $i $log_dir >> /opt/a/$dir-access.log done > $log_dir else dir=`cat /opt/log_date.txt| sed 's#/#-#g' ` mv $log_dir /opt/a/$dir-access.log kill -USR1 $(cat /var/run/nginx.pid) #通过USER1信号通知nginx重新打开日志文件 $nginx_sbin force-reload fi {lamp/}一个简单的分割脚本#!/bin/bash Dateformat=`date +%Y%m%d` Basedir="/usr/local/nginx" Nginxlogdir="$Basedir/logs" Logname="access_www" [ -d $Nginxlogdir ] && cd $Nginxlogdir || exit 1 [ -f ${Logname}.log ] || exit 1 mv ${Logname}.log ${Dateformat}_${Logname}.log $Basedir/sbin/nginx -s reload {lamp/}一个非常耗时的日志分割脚本cat access.log | while read i a b t c do date_dir=`echo $t|sed 's#\[##'|sed 's#\/#-#g'|cut -d: -f1` echo $i $a $b $t $c >> /tmp/log/$date_dir-log.txt date=`echo $date_dir| sed 's#-#\.#g'` sed -i "/$i.*$date/d" access.log done
