一个简单的nginx日志切割shell脚本

脚本如下：

#!/bin/bash
#Rotate the Nginx logs to prevent a single logfile from consuming too much disk space. 
# 每天产生一个当天的日志文件  KEEPTIME之前的文件 会被转移到 备份目录

LOGS_PATH=/data/logs/nginx
CURRENT_YEAR=$(date +%Y)
YEAR_PATH=$LOGS_PATH/$CURRENT_YEAR #日志备份目录

# 确保年份文件夹存在  若存在 -p也不会报错
mkdir -p $YEAR_PATH

YESTERDAY=$(date -d "yesterday" +%Y-%m-%d)
KEEPTIME=$(date -d "-30 days" +%Y-%m-%d)

mv ${LOGS_PATH}/access.log ${LOGS_PATH}/access_${YESTERDAY}.log
mv ${LOGS_PATH}/error.log ${LOGS_PATH}/error_${YESTERDAY}.log

kill -USR1 $(cat /usr/local/nginx/logs/nginx.pid)

##mv logs 30 days ago to year path
if [ -f ${LOGS_PATH}/access_${KEEPTIME}.log ]; then
	mv ${LOGS_PATH}/access_${KEEPTIME}.log $YEAR_PATH
fi

if [ -f ${LOGS_PATH}/error_${KEEPTIME}.log ]; then
	mv ${LOGS_PATH}/error_${KEEPTIME}.log $YEAR_PATH
fi
