CentOS7中Nginx日志定时拆分实现过程详解

#!/bin/bash
folder=`date -d yesterday +%Y%m`
rq=`date -d yesterday +%Y%m%d`
# 原始日志路径
logs_path="/var/log/nginx/sitename.com/"
# 日志备份路径
logs_backup_path="/var/log/nginx/sitename.com/$folder"
# 要分割的日志
logs_access="access"
logs_error="error"
# 创建备份路径
[ -d $logs_backup_path ]||mkdir -p $logs_backup_path
# 将日志移入备份文件夹
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
# 终止nginx的pid
pid_path="/var/run/nginx.pid"
kill -USR1 $(cat $pid_path)
