#!/bin/bash     #cut_nginx_log.sh     datetime=$(date -d "-1 day" "+%y%m%d")     log_path="/usr/local/nginx/logs"     pid_path="/usr/local/nginx/logs/nginx.pid"     [ -d $log_path/backup ] || mkdir -p $log_path/backup     if [ -f $pid_path ]     then     mv $log_path/access.log $log_path/backup/access.log-$datetime     kill -usr1 $(cat $pid_path)     find $log_path/backup -mtime +30 | xargs rm -f     else     echo "error,nginx is not working!" | tee -a /var/log/messages     fi

#!/bin/bash    #cut_nginx_log.sh        datetime=$(date -d "-1 day" "+%y%m%d")        //时间,date -d "-1 day"代表日期减1    log_path="/usr/local/nginx/logs"             //日志的存放位置    pid_path="/usr/local/nginx/logs/nginx.pid"   //进程的pid号，有pid号代表 进程还活着    [ -d $log_path/backup ] || mkdir -p $log_path/backup   //如果$log_path/backup不是一个目录则创    建$log_path/backup目录    if [ -f $pid_path ]                                //如果$pid_path是一个文件    then    mv $log_path/access.log $log_path/backup/access.log-$datetime  //那么移动旧日志的文件到新目录    下以此来实现分割    kill -usr1 $(cat $pid_path)                                    //usr1代表信号，他会给进程传一    个信号让进程生成一个新的日志    find $log_path/backup -mtime +30 | xargs rm -f                //查找30天前的日志并删除    else    echo "error,nginx is not working!" | tee -a /var/log/messages  //否则提示nginx is not working且追加到日志中    fi
