STEP 3: Change the Apache SSL port and Apache non-SSL IP/port

Tweak settings >> Search: Apache SSL port and Apache non-SSL IP/port

Apache non-SSL IP/port
0.0.0.0:80 default >> Change to: 0.0.0.0:8080

Apache SSL port
0.0.0.0:443 default >> Change to: 0.0.0.0:8443

Save and Re-Check Apache port:

[root@vDDoS-cPanel ~]# netstat -lntup|grep httpd
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      993/httpd
tcp        0      0 0.0.0.0:8443            0.0.0.0:*               LISTEN      993/httpd
tcp6       0      0 :::8080                 :::*                    LISTEN      993/httpd
tcp6       0      0 :::8443                 :::*                    LISTEN      993/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://0.0.0.0:80    http://1.2.3.4:8080    no    no      no           no
default         https://0.0.0.0:443  https://1.2.3.4:8443   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://1.2.3.4:8080
HTTPS_Backend    https://1.2.3.4:8443


Set Crontab:

echo '*/15 * * * * root /usr/bin/vddos-autoadd panel cpanel 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
