#!/bin/bash year=`date +%Y` month=`date +%m` day=`date +%d` logs_backup_path="/home/nginx/logs_backup/$year$month" #日志存储路径 logs_path="/home/nginx/logs/" #要切割的日志路径 logs_access="access" #要切割的日志 logs_error="error" pid_path="/home/nginx/logs/nginx.pid" #nginx的pid [ -d $logs_backup_path ]||mkdir -p $logs_backup_path rq=`date +%Y%m%d` #mv ${logs_path}${logs_access}.log ${logs_backup_path}/${logs_access}_${rq}.log mv ${logs_path}${logs_error}.log ${logs_backup_path}/${logs_error}_${rq}.log kill -USR1 $(cat /home/nginx/logs/nginx.pid)
crontab -e #注意是 -e
