如果想看看Nginx有多少IP访问量，有哪些国家访问，并显示IP地址的归属地分布，python可以结合使用高春辉老师ipip.net【免费版 IP 地址数据库】，Shell可以使用nali，我这边主要使用python语言来实现需求,并将查询结果以邮件形式发送，也是为了学习和回顾python语言。很感谢高春辉老师提供的免费版IP地址数据库。

一、Ningx日志如下：

二、下载 免费版 IP 地址数据库

 #wget  http://s.qdcdn.com/17mon/17monipdb.zip
 #unzip  17monipdb.zip

三、IP库常见问题FAQ

 示例代码：

import os
from ipip import IP
from ipip import IPX
IP.load(os.path.abspath("mydata4vipday2.dat"))
print IP.find("118.28.8.8")
IPX.load(os.path.abspath("mydata4vipday2.datx"))
print IPX.find("118.28.8.8")

 执行输出：

中国  天津  天津      鹏博士
中国  天津  天津      鹏博士   39.128399   117.185112  Asia/Shanghai   UTC+8   120000
