python 获取ip信息（国家、城市等）

安装geoip2包：pip install geoip2
下载数据库文件：http://geolite.maxmind.com/download/geoip/database/GeoLite2-Country.tar.gz
解压出GeoLite2-City.mmdb文件
新建py文件，内容如下：

import geoip2.database

reader = geoip2.database.Reader('./GeoLite2-City.mmdb')  # mmdb文件路径
c= reader.country('123.123.123.123')
print c.country.names   # 国家名
print c.country.code  # 国家代码
# 其他信息看源码

** 以下为配置自动更新数据库的步骤 **

在github下载geoipupdate最新包：geoipupdate-3.1.1.tar.gz
解压并安装：

tar -zxvf geoipupdate-3.1.1.tar.gz
./configure
sudo make
sudo make install 

修改配置文件：/usr/local/etc/GeoIP.conf

# The following AccountID and LicenseKey are required placeholders.
# For geoipupdate versions earlier than 2.5.0, use UserId here instead of AccountID.
