python——ip加入nginx黑名单

发布时间:2019-07-23 09:46:11编辑:auto阅读(1549)

    需求:因nginx做了防刷机制之后, error.log 会出现ip刷服务器,也被nginx挡掉了,并没有具体刷到后端服务器,但error.log多次出现ip,现计划把出现5次以上的ip写入黑名单。


    nginx log日志格式:

    2016/09/05 01:11:07 [info] 1354#0: *11981355139 limiting connections by zone "limit", client: 111.164.58.3, server: api.test.cn, request: "GET /test/test?_at=28&_av=103&_avn=1.1.2&_c=%E4%B8%8A%E6%B5%B7&_i=a4fe3bb262c171054f7ca01d8af58337&_la=0&_lo=0&_pm=iPhone&_pv=9.33.2&_pvt=2&_s=2&_sg=FF4C1556E48DBDD8A2&_sh=1136&_sw=6540&_uuid=a4fe3bb262c171054f7c55a01d8af58337&m=2791763&mid=48&pi=1&ps=10&t=1&t2=6Af95DlK55RkmekO-7W8HiTQZysThxEVOE HTTP/1.0", host: "api.test.cn"


    写入黑名单文件:

    [root@ ~]# more /mnt/nginx/conf/refuseip.conf 

    deny 111.164.58.3;


    注:以上日志格式正确,ip和链接有篡改过,无法直接访问。


    #!/usr/bin/python

    # -*- coding:UTF-8 -*-



    import subprocess

    import os

    IP = ("tail -f /mnt/log/nginx/error.log")


    file="/mnt/nginx/conf/refuseip.conf"


    child= subprocess.Popen(IP,shell=True,stdout=subprocess.PIPE)

    flag=[]

    while True:

        line = child.stdout.readline()

        if line.find("limit") != -1:


            j = line.split()[11].split(",")[0]

            flag.append(j)


            delete=flag[-1]

            num=flag.count(delete)

            if num>=5:

                for i in range(num):

                    index=flag.index(delete)

                    del flag[index]

                print flag


                f=open(file,'a')

                f.write("deny " +delete+";"+'\n')

                f.close()
