python实现日志按天分割

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

import re,os,commands
a=open('/python/access.log','r')

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()
