#!/bin/bash
#此脚本用于自动分割php日志,error.log
#每天00:01执行此脚本 将前一天的errors.log重命名为errors-xxxx-xx-xx.log格式，并重新打开日志文件
#Nginx日志文件所在目录
LOG_PATH=/data/services/logs/php/
#获取昨天的日期
YESTERDAY=$(date -d "yesterday" +%Y-%m-%d)
#获取pid文件路径
PID=/var/run/php-fpm.pid
#分割日志
for logfile in php_errors jlog;
do
ls -l ${LOG_PATH}${logfile}.log
mv ${LOG_PATH}${logfile}.log ${LOG_PATH}${logfile}.log-${YESTERDAY}.log;
done
#mv ${LOG_PATH}nginx_error.log ${LOG_PATH}nginx_error-${YESTERDAY}.log
#向php主进程发送USR1信号，重新打开日志文件
kill -USR1 `cat ${PID}`
chown nginx.nginx /data/services/logs/php/ -R
