Discuz!论坛建站防DDOS攻击脚本[适用于宝塔、AMH linux服务器]
Discuz!论坛建站防DDOS攻击脚本[适用于宝塔、AMH linux服务器]：原理：用Cron计划任务定时执行脚本统计单个IP的最大连接数，如果超过阈值则用APF或者iptables来阻止，并在预设的阻止时间后释放。安装：wget https://www.dz-x.net/scripts/install.sh
chmod +x install.sh
./install.sh
卸载：
wget https://www.dz-x.net/scripts/uninstall.sh
chmod +x uninstall.sh
./uninstall.sh
配置：
/usr/local/ddos/ddos.conf
##### Paths of the script and other files
PROGDIR="/usr/local/ddos"
PROG="/usr/local/ddos/ddos.sh"
IGNORE_IP_LIST="/usr/local/ddos/ignore.ip.list"
CRON="/etc/cron.d/ddos.cron"
APF="/etc/apf/apf"
IPT="/sbin/iptables"
##### frequency in minutes for running the script
##### Caution: Every time this setting is changed, run the script with --cron 多少分钟执行一次统计
##### option so that the new frequency takes effect
FREQ=1
##### How many connections define a bad IP? Indicate that below. 当一个IP的最大连接是多少的时候阻止它
NO_OF_CONNECTIONS=150
##### APF_BAN=1 (Make sure your APF version is atleast 0.96，确定安装APF并且版本大雨0.96)
##### APF_BAN=0 (Uses iptables for banning ips instead of APF，用iptables代理APF)
APF_BAN=1
##### KILL=0 (Bad IPs are'nt banned, good for interactive execution of script)
##### KILL=1 (Recommended setting，推荐设置)
KILL=1
##### An email is sent to the following address when an IP is banned.阻止一个IP后通知谁
##### Blank would suppress sending of mails
EMAIL_TO="root"
##### Number of seconds the banned
