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 osimport timepath1='/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 lykimport re,os,commandsa=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()
