STEP 1: Install VestaCP

curl -O http://vestacp.com/pub/vst-install.sh
bash vst-install.sh

More documentation:
https://vestacp.com/install

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

STEP 3: Change Apache Default Port

By default VestaCP uses Apache or Nginx running on port 80, 443. Or Nginx proxy Apache too, we can reconfigure these Webservers to listen on another port so that vDDoS can proxy on them.

More documentation:
https://vestacp.com/docs/#how-to-remove-nginx-rhel-centos


For example, I switch Apache to port 8080 and 8443:

cp /usr/local/vesta/conf/vesta.conf /usr/local/vesta/conf/vesta.conf.bak
nano /usr/local/vesta/conf/vesta.conf

WEB_SYSTEM='httpd'
WEB_RGROUPS='apache'
WEB_PORT='8080'
WEB_SSL_PORT='8443'
WEB_SSL='mod_ssl'
STATS_SYSTEM='webalizer,awstats'
FTP_SYSTEM='vsftpd'
DNS_SYSTEM='named'
MAIL_SYSTEM='exim'
IMAP_SYSTEM='dovecot'
CRON_SYSTEM='crond'
FIREWALL_SYSTEM='iptables'
DISK_QUOTA='yes'
BACKUP_SYSTEM='local'
LANGUAGE='en'
VERSION='0.9.8'
DB_SYSTEM='mysql'
SOFTACULOUS='yes'

Save & Rebuild vhost configs:

for user in $(v-list-sys-users plain); do v-rebuild-web-domains $user; done




Re-Check Apache port:

[root@vesta ~]# netstat -lntup|grep httpd
tcp        0      0 1.2.3.4:8443      0.0.0.0:*               LISTEN      879/httpd
tcp        0      0 1.2.3.4:8080      0.0.0.0:*               LISTEN      879/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 vestacp 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
