nginx日志切割脚本

#!/bin/sh
#初始化
logs_path="/usr/local/nginx/logs"
pid_path="/usr/local/nginx/logs/nginx.pid"
YESTERDAY=$(date -d "yesterday" +%Y-%m-%d)

##移动文件
mv ${logs_path}/access.log ${logs_path}/${YESTERDAY}.access.log

##向Nginx 主进程发送 USR1 信号,USR1 信号是重新打开日志文件  
kill -USR1 `cat ${pid_path}`

#删除7天前的日志
cd $logs_path
find . -ctime +7 -name "20[1-9][3-9]*" | xargs rm -f
exit 0
