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
