使用shell脚本对Nginx日志进行切分的示例代码

log_format main '$remote_addr - $remote_user [$time_local] "$request" '
          $status $body_bytes_sent "$http_referer" '
         '"$http_user_agent" "$http_x_forwarded_for"';

#!/bin/bash
base_path='/usr/local/nginx/logs'
log_path=$(date -d yesterday +"%Y%m")
day=$(date -d yesterday +"%d")
mkdir -p $base_path/$log_path
mv $base_path/access.log $base_path/$log_path/access_$day.log
kill -USR1 `cat /usr/local/nginx/logs/nginx.pid`
