本文实例为大家分享了python实现日志按天分割的具体代码，供大家参考，具体内容如下

日志格式：

1.1.1.1 - - [30/Apr/2015:00:34:55 +0800] “POST /iDataService/services/MemRoomService HTTP/1.0” 200 405 “-” “Axis/1.4” “-”

1.1.1.1 - - [30/Apr/2015:00:34:55 +0800] “POST /iDataService/services/CutLoginService HTTP/1.1” 200 438 “-” “Apache CXF 2.7.8” “-”

1.1.1.1 - - [20/Apr/2015:00:34:55 +0800] “POST /iDataService/services/NoticeListService HTTP/1.1” 200 656 “-” “Apache CXF 2.7.8” “-”

1.1.1.1 - - [30/Apr/2016:00:34:56 +0800] “POST /iDataService/services/MemSelfQueryService HTTP/1.0” 200 1344 “-” “Axis/1.4” “-“

分割要求：

对日子进行按天分割，文件名称如access.log-20160101

#!/usr/bin/env python

# -- conding:utf-8 --

#

import os

import time

path1='/lianxi/python/split/lianxi1'

file=open(path1,'r')

for line in file:

str=line.split()[3]

otime=str[1:12]

time_jieshu = time.strptime(otime, '%d/%b/%Y')

time_jieshu = int(time.mktime(time_jieshu))

ntime=time.strftime('%Y%m%d',time.localtime(time_jieshu))

# print ntime

log_file='/lianxi/python/split/access.log-%s' %ntime

with open(log_file,'a') as f:

if not os.path.exists(log_file):

os.mknod(log_file)

# f.write(line)

# else:

f.write(line)

f.close()

#!/usr/bin/python

#coding=utf-8

#author lyk

import re,os,commands

a=open('/python/access.log','r')

exc_month={'Apr':'04','Aug':'08','Dec':'12','Feb':'02','Jan':'01','Jul':'07','Jun':'06','Mar':'03','May':'05','Nov':'11','Oct':'10','Sep':'09'}

def touch_file():

blist=[]

commands.getoutput('rm -rf /accesslog/*')

for i in a:

blist.append(re.findall(r"\[(.+?):",i)[0])

new_blist=[]

for j in blist:

if j.replace('/','.') not in new_blist:

new_blist.append(j.replace('/','.'))

for j in new_blist:

commands.getoutput('touch /accesslog/access.log-%s'%(j[7:17]+exc_month[j[3:6]]+j[0:2]))

def append_file():

for i in a:

mfile=re.findall(r"\[(.+?):",i)[0].replace('/','')

f=open("/accesslog/access.log-"+mfile[5:9]+exc_month[mfile[2:5]]+mfile[0:2],'a')

f.write(i)

f.close()

def tar_file():

for i in commands.getoutput('ls /accesslog').splitlines():

commands.getoutput("gzip /accesslog/%s"%i)

if __name__=='__main__':

touch_file()

append_file()

tar_file()
