图文详解nginx日志切割的实现

#!/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
