python通过日志分析加入黑名单

监控nginx日志,若有人攻击,则加入黑名单,操作步骤如下:

1.读取日志文件

2.分隔文件,取出ip

3.将取出的ip放入list,然后判读ip的次数

4.若超过设定的次数,则加入黑名单

日志信息如下:

代码如下:

import?os
import?time
#os.system('ipconfig')??#用来操作系统命令
while?True:
????list_ip?=?[]
????with?open('access.log')?as?fp:
????????for?line?in?fp:
????????????ip?=?line.split()[0]???#获取ip
????????????list_ip.append(ip)
????os.system('>access.log')???#清空文件内容
????set_ips?=?set(list_ip)?????#去除重复的ip值
????for?ip?in?set_ips:
????????if?list_ip.count(ip)?>200:??#若list_ip内重复出现的ip次数大于200,则加入黑名单
????????????os.system('iptables?-I?INPUT?1?-p?tcp?-s?%s??-j?DROP'?%?ip)
????time.sleep(60)
