#!/bin/bash

#cut_nginx_log.sh



datetime=$(date -d "-1 day" "+%Y%m%d")??????? //時間,date -d "-1 day"代表日期減1

log_path="/usr/local/nginx/logs"???????????? //日志的存放位置

pid_path="/usr/local/nginx/logs/nginx.pid"?? //進程的PID號，有PID號代表 進程還活著

[ -d $log_path/backup ] || mkdir -p $log_path/backup?? //如果$log_path/backup不是一個目錄則創(chuàng)

建$log_path/backup目錄

if [ -f $pid_path ]??????????????????????????????? //如果$pid_path是一個文件

then

mv $log_path/access.log $log_path/backup/access.log-$datetime? //那么移動舊日志的文件到新目錄

下以此來實現分割

kill -USR1 $(cat $pid_path)??????????????????????????????????? //USR1代表信號，他會給進程傳一

個信號讓進程生成一個新的日志

find $log_path/backup -mtime +30 | xargs rm -f??????????????? //查找30天前的日志并刪除

else

echo "Error,Nginx is not working!" | tee -a /var/log/messages? //否則提示nginx is not working且追加到日志中

fi
