python读取日志，存入mysql

1、从 http://www.almhuette-raith.at/apache-log/access.log 下载 1万条日志记录，保存为一个文件，读取文件并解析日志，从日志中提取ip, time_local, http_method, url, http_status, body_bytes_sent , http_referer, ua字段，以制表符分割。
在mysql中创建表，将刚才解析后的结果存入mysql表中。

2、在mysql中，使用sql查询出现次数最多的ip，以及该ip的访问次数。 这里写代码片

file_data

# coding:utf-8
# ip, time_local, http_method, url, http_status, body_bytes_sent , http_referer, ua
import re

data_all = {}
data_ev = {}

print("开始提取。。。")
with open("access_parts.log") as f:
count = 1
for line in f.readlines():
line = line.strip('\n')
line = re.split("\s|-", line)
# print(line)
data_ev["ip"] = line[0]
data_ev["time_local"] = line[5].split('[')[1]
data_ev["http_method"] = line[7].split('"')[1]
data_ev["url"] = line[8]
data_ev["http_status"] = line[9]
if line[10] == '-':
data_ev["body_bytes_sent"] = 0
else:
data_ev["body_bytes_sent"] = line[10]
data_ev["http_referer"] = line[11].split('"')
data_ev["ua"] = ' '.join(line[12:23]).split('"')
if data_ev["http_method"] == 'GET':
data_ev["ua"] = data_ev["ua"][3]
else:
data_ev["ua"] = data_ev["ua"][1] + data_ev["ua"][3]
print(data_ev)
data_all[count] = data_ev
# print("已完成"+count+"行。。。")
count += 1
