nginx实现按日期进行日志分割

#!/bin/bash

local_path=/usr/local/nginx/logs

cd $local_path

if [ !-d date_log ] ;then
    mkdir date_log
fi

mv access_nginx.log $local_path/date_log/access_`date -d "yesterday" +%Y%m%d`
nginx_pid=`ps -ef |grep -v grep |grep "nginx: master process"|awk -F" " ‘{print $2}‘`
`sudo kill -USR1 $nginx_pid`
