Nginx access日志格式如下:

使用的nginx默认日志格式$remote_addr - $remote_user [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent" "$http_x_forwarded_for"'

Nginx access 日志内容如下:
182.19.31.129 - - [2013-08-13T00:00:01-07:00] "GET /css/anniversary.css HTTP/1.1" 304 0 "http://www.chlinux.net/" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36" "-"

mysql 数据表

CREATE TABLE nginx_log.downloads (
`IP` TINYTEXT,
`Time` TINYTEXT,
`Request` TEXT,
`Status` TINYTEXT,
`Body` SMALLINT,
`Url` text,
`Agent` TINYTEXT,
`OS` TINYTEXT,
`Browser` TINYTEXT
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

下面是Python 分析nginx的Python代码:

#!/usr/bin/env python
#coding:utf8
import os
import fileinput
import re
import sys
import MySQLdb
#日志的位置
logfile=open("access_20130812.log")
#使用的nginx默认日志格式$remote_addr - $remote_user [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent" "$http_x_forwarded_for"'
