AntiDDoS aaPanel vDDoS

STEP 1: Install aaPanel (CentOS)

yum install -y wget && wget -O install.sh http://www.aapanel.com/script/install_6.0_en.sh && bash install.sh forum

(Install LAMP: Apache PHP MySQL)

STEP 2: Install vDDoS Proxy Protection

vDDoS Proxy Protection is free software to provide a Reverse Proxy Server HTTP(S) protocols. It act as a Layer 7 Firewall Filter & Mitigate DOS, DDOS, SYN Floods, or HTTP Floods attack to protect your website.

wget https://files.voduy.com/vDDoS-Proxy-Protection/latest.sh ; chmod 700 latest.sh ; bash latest.sh

More documentation:
https://vddos.voduy.com

STEP 3: Change Apache Default IP

By default aaPanel LAMP uses Apache running on IP port 0.0.0.0:80, 0.0.0.0:443. We can reconfigure these Webservers to listen on another IP so that vDDoS can proxy on them.

[NOTE: you need to add at least 1 website (HTTPS) to aaPanel before continuing (you can use self-signed ssl certificate)]

Change Apache Default IP:

cp /www/server/apache/conf/httpd.conf /www/server/apache/conf/httpd.conf.vddosbak
nano /www/server/apache/conf/httpd.conf

Find:

Listen 80
Listen 443

Change to:

Listen 127.0.0.1:80
Listen 127.0.0.1:443

AntiDDoS aaPanel vDDoS

Save & Restart Apache:

service httpd restart

Re-Check Apache port:

[root@aaPanel ~]# netstat -lntup|grep httpd
tcp        0      0 127.0.0.1:443           0.0.0.0:*               LISTEN      2738/httpd
tcp        0      0 127.0.0.1:80            0.0.0.0:*               LISTEN      2738/httpd
tcp6       0      0 :::888                  :::*                    LISTEN      2738/httpd

STEP 4: Config vDDoS Proxy Protection

For example, the IP Addr of your server is 1.2.3.4:

nano /vddos/conf.d/website.conf

# Website       Listen               Backend                  Cache Security SSL-Prikey   SSL-CRTkey
default         http://1.2.3.4:80    http://127.0.0.1:80    no    no      no           no
default         https://1.2.3.4:443  https://127.0.0.1:443   no    no      /vddos/ssl/your-domain.com.pri /vddos/ssl/your-domain.com.crt

Restart vDDoS service after you have configured:

/usr/bin/vddos restart

STEP 5: Config vDDoS Auto Add

vDDoS Auto Add is a addon support for vDDoS Proxy Protection - Monitor Domains/Aliasdomains/Subdomains in Panel Hosting, Web Server, List Domain, Virtual Host... and automatically add them into the website.conf file.

nano /vddos/auto-add/setting.conf

# Default Setting for vddos-add command:

SSL				auto
DNS_sleep 		66
DNS_alias_mode	no
Cache			no
Security		no
HTTP_Listen		http://1.2.3.4:80
HTTPS_Listen	https://1.2.3.4:443
HTTP_Backend	http://127.0.0.1:80
HTTPS_Backend	https://127.0.0.1:443

Set Crontab:

ln -s /usr/bin/httpd /usr/sbin/httpd
echo '*/15 * * * * root /usr/bin/vddos-autoadd webserver apache' >> /etc/crontab

STEP 6: Config vDDoS Auto Switch

vDDoS Auto Switch is a addon support for vDDoS Proxy Protection - Automatically identifies overloaded websites and changes their Security Mode.

nano /vddos/auto-switch/setting.conf

# This is the default configuration for "sensor-switch.sh" and "vddos-autoswitch.sh"

hostname="vDDoS Master"							#(Name this server, it will show up in Email notifications)

vddos_master_slave_mode="no"					#(Turn on "yes" if your system has slave servers, want to sync affter switch like master)
backend_url_check="no"			#(Put the URL of the backend. Ex: https://1.1.1.1:8443/ (make sure Backend status response is "200"))

send_notifications="no"						#(Turn on "yes" if you want receive notification)
smtp_server="smtps://smtp.gmail.com"		#(SMTP Server)
smtp_username="xxx@gmail.com"				#(Your Mail)
smtp_password="xxxxxxxxxxxxx" 				#(Get your Apps password for Gmail from https://security.google.com/settings/security/apppasswords)
send_notifications_to="xxxx@gmail.com"		#(Your Email Address will receive notification)


maximum_allowable_delay_for_backend=2 			#(Means: If Backend (status response "200") is slower than 2s, vDDoS will enable challenge mode)
maximum_allowable_delay_for_website=2 			#(Means: If Website (status response "200") is slower than 2s, vDDoS will enable challenge mode)

default_switch_mode_not_attack="no"				#(Default Mode vDDoS use when it's not under attacked)
default_switch_mode_under_attack="high"			#(Default Mode vDDoS use when it's under attack)
default_waiting_time_to_release="60"			#(For example 60 minutes, release time from challenge)

Crontab vDDoS Auto Switch:

echo '*/5 * * * * root /usr/bin/vddos-autoswitch checkalldomain high' >> /etc/crontab
echo '0 */3 * * * root /usr/bin/vddos-switch allsite no && /usr/bin/vddos reload' >> /etc/crontab
echo '* * * * * root /usr/bin/vddos-sensor' >> /etc/crontab
