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)
