宝塔面板建站后接入CF自动开启5秒盾证码脚本

有大神分享了CF自动开启5秒盾 + 验证码脚本,原理就是通过检测系统负载(cpu或load)自动开启cloudflare UAM和challenge质询(验证码)!!

这里分享下宝塔面板下如何用起来,使用的前提是你的域名需要接入cloudflare。

1、简介

项目:https://github.com/jiuqiMax/autouam

2、申请api_key

开搞之前先申请CloudFlare API KEY,登录cf之后,点击右上角的个人资料(My Profile),选择{API Tokens}选择{Global API Key}

3、申请zone_id

回到后台首页,点击域名管理,在右侧就可以看到Zone ID

4、代码

脚本代码如下:

#!/bin/bash

#
# Usage:
# screen -dmS autouam &&
# screen -x -S autouam -p 0 -X stuff "bash /root/autouam.sh" &&
# screen -x -S autouam -p 0 -X stuff $'\n'
#

mode="load"
# 两种模式可选,一:cpu 二:load

challenge="1"
# 是否同时开启验证码质询 设为1即开启

keeptime="300"
# ≈开盾最小时间,如60 则开盾60秒内负载降低不会关,60秒后关

interval="0.5"
# 检测间隔时间,默认0.5秒

email="wdnmd@cloudflare.com"
# CloudFlare 账号邮箱

api_key="(´இ皿இ`)"
# CloudFlare API KEY

zone_id="ಥ_ಥ"
# 区域ID 在域名的概述页面获取

default_security_level="high"
# 默认安全等级 关闭UAM时将会把安全等级调整为它

api_url="https://api.cloudflare.com/client/v4/zones/$zone_id/settings/security_level"
# API的地址

api_url1="https://api.cloudflare.com/client/v4/zones/$zone_id/firewall/access_rules/rules"
# API的地址之二

# 安装依赖

注意:该修改的地方,要修改。

5、计划任务

宝塔面板的计划任务中新建一个脚本任务

保存之后,可以试着执行下看看效果:

6、最后

如果你的站点被攻击频繁,可以试着把执行周期改成每天,或者每小时啥的,这个自行调整。如果有更新,请自行进入项目获取最新脚本。

注意!默认challenge=1,将在开启UAM的同时开启验证码。如果你不想,请将它设为0
