AntiDDoS-for-aaPanel-with-vDDoS-Proxy-Protection.png



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)


More documentation:
https://forum.aapanel.com/d/9-aapanel-linux-panel-6812-installation-tutorial


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

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:

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="x...@gmail.com"                #(Your Mail)
smtp_password="xxxxxxxxxxxxx"                 #(Get your Apps password for Gmail from https://security.google.com/settings/security/apppasswords)
send_notifications_to="xx...@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

Something we will get 520 in CloudFlare when using vDDoS proxy for Apache, the real reason for this problem lies in Apache, Apache being configured with https requiring an http/2 upgrade status in respone http and make CloudFlare not understand, thus CloudFlare has returned error 520 occasionally.


aaPanel:
nano /www/server/apache/conf/httpd.conf

<IfModule http2_module>
ProtocolsHonorOrder On
#Protocols h2 http/1.1
Protocols http/1.1 h2
</IfModule>


Edit:
#Protocols h2 http/1.1
To:
Protocols http/1.1 h2

[AntiDDoS] for aaPanel with vDDoS Proxy Protection (LNMP Nginx Version)


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 LNMP: Nginx PHP MySQL)


More documentation:
https://forum.aapanel.com/d/9-aapanel-linux-panel-6812-installation-tutorial


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 Nginx Default Port

By default aaPanel LNMP uses Nginx 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)]

cat /vddos/ssl/your-domain.com.*

Change Nginx Default Port:

cp -r /www/server/panel/vhost/nginx /www/server/panel/vhost/nginx.vddos.bak

Change port for HTTP:

s='80;' ; r='88;'
sed -i "s#$s#$r#g" /www/server/panel/vhost/nginx/*.conf



Change port for HTTPS:

s='443' ; r='999'
sed -i "s#$s#$r#g" /www/server/panel/vhost/nginx/*.conf



Save & Restart Nginx:

service nginx restart

Re-Check Nginx port:

[root@vps-aaPanel ~]# netstat -lntup|grep nginx
tcp        0      0 0.0.0.0:999             0.0.0.0:*               LISTEN      24074/nginx: master
tcp        0      0 0.0.0.0:88              0.0.0.0:*               LISTEN      24074/nginx: master
tcp        0      0 0.0.0.0:888             0.0.0.0:*               LISTEN      24074/nginx: master






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://0.0.0.0:80    http://1.2.3.4:88    no    no      no           no
default         https://0.0.0.0:443  https://1.2.3.4:999   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://0.0.0.0:80
HTTPS_Listen      https://0.0.0.0:443
HTTP_Backend      http://1.2.3.4:88
HTTPS_Backend     https://1.2.3.4:999


Set Crontab:

echo '*/15 * * * * root /usr/bin/vddos-autoadd webserver nginx' >> /etc/crontab

Set Real IP vDDoS Proxy

Ex your server IP Addr is 1.2.3.4:

nano /www/server/nginx/conf/nginx.conf
....
....
#AAPANEL_FASTCGI_CONF_END



set_real_ip_from 127.0.0.1;
set_real_ip_from 1.2.3.4;
real_ip_header    X-Forwarded-For;
real_ip_recursive on;




include       mime.types;
....
....


Restart Nginx:

service nginx reload
