How to / [ANTIDDOS] for CWP Panel with vDDoS Proxy Protection
« on: June 16, 2018, 04:34:36 PM »
ANTIDDOS CWP Panel (Update 2018 - How to full install)



STEP 1: Install CWP Panel
Code: [Select]
cd /usr/local/src
wget http://centos-webpanel.com/cwp-el7-latest
sh cwp-el7-latest

More documentation: 
http://centos-webpanel.com/cwp-installation

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 Filter & Mitigate DOS, DDOS, SYN Floods, or HTTP Floods attack to protect your website.

Code: [Select]
curl -L https://github.com/duy13/vDDoS-Protection/raw/master/latest.sh -o latest.sh
chmod 700 latest.sh
bash latest.sh

STEP 3: Change Apache Default Port

By default, CWP uses Apache alone and runs on port 80, 443. We can use the function: Setup default Web Servers at Apache Settings >> Select WebServer



Change it into: Apache & Varnish Cache & Nginx Reverse Proxy or Apache & Nginx Reverse Proxy, So Apache will be listened to at another port is 8181 and 8443; to facilitate our proxying.


Click Save and Re-check Apache port:

Code: [Select]
[root@vDDoS-CWP Panel ~]# netstat -lntup|grep httpd; netstat -lntup|grep nginx; netstat -lntup|grep varnishd
tcp6       0      0 :::8181         :::*                    LISTEN      1304/httpd
tcp6       0      0 :::8443         :::*                    LISTEN      1304/httpd
tcp        0      0 1.2.3.4:80      0.0.0.0:*               LISTEN      5481/nginx: master
tcp        0      0 1.2.3.4:443     0.0.0.0:*               LISTEN      5481/nginx: master
tcp        0      0 127.0.0.1:6082  0.0.0.0:*               LISTEN      1418/varnishd
tcp        0      0 0.0.0.0:82      0.0.0.0:*               LISTEN      1418/varnishd
tcp6       0      0 :::82           :::*                    LISTEN      1418/varnishd

It can be seen that Nginx listened at 80 and 443, then it proxyed to port 82 of Varnish cache server then Varnish continued forwarding traffic to Apache at port 8181.
So you can stop Nginx and replacing it with vDDoS, Reverse Proxy for vDDoS to any port of Apache or Varnish (With Varnish you will be cached and reach faster speeds)

Code: [Select]
service nginx stop
chkconfig nginx off

STEP 4: Config vDDoS Proxy Protection

The following example assumes the IP address of the server you are 1.2.3.4:

Code: [Select]
nano /vddos/conf.d/website.conf

# Website       Listen               Backend                  Cache Security SSL-Prikey   SSL-CRTkey
default         http://0.0.0.0:80    http://1.2.3.4:8181    no    no      no           no
default         https://0.0.0.0:443  http://1.2.3.4:8181   no    no      /vddos/ssl/your-domain.com.pri /vddos/ssl/your-domain.com.crt


Configuration like the above you will use directly from vDDoS reverse proxy to Apache port, If you want to use port of Varnish cache server then you can configure as follows:

Code: [Select]
nano /vddos/conf.d/website.conf

# Website       Listen               Backend                  Cache Security SSL-Prikey   SSL-CRTkey
default         http://0.0.0.0:80    http://1.2.3.4:82    no    no      no           no
default         https://0.0.0.0:443  http://1.2.3.4:82   no    no      /vddos/ssl/your-domain.com.pri /vddos/ssl/your-domain.com.crt

Restart vDDoS service after you have configured:
Code: [Select]
/usr/bin/vddos restart
Auto-start vDDoS services on boot:
Code: [Select]
/usr/bin/vddos autostart



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.

Code: [Select]
nano /vddos/auto-add/setting.conf

Default Setting for vddos-add command:

SSL Auto
Cache no
Security no
HTTP_Listen http://0.0.0.0:80
HTTPS_Listen https://0.0.0.0:443
HTTP_Backend http://1.2.3.4:82
HTTPS_Backend http://1.2.3.4:82

Crontab CWP Panel:
Code: [Select]
echo '*/25 * * * * root /usr/bin/vddos-autoadd panel cwp 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.

Code: [Select]
echo '*/6 * * * * root /usr/bin/vddos-autoswitch checkalldomain high' >> /etc/crontab
echo '0 */3 * * * root /usr/bin/vddos-autoswitch flushalldomain /vddos/conf.d/website.conf no' >> /etc/crontab

CentOS-WebPanel Bugs / Re: Website Down
« on: December 24, 2017, 04:11:09 PM »
Some days my website often decreased so can not be accessed. all run normally again after I reboot the server. And after a few hours later this happens again. I do not know why, anyone can help?


You may have been attacked by ddos. Please check the connection number to your server:
Code: [Select]
netstat -an |grep ":80" |awk '{print $5}' | sed s/::ffff://g | cut -d: -f1 |sort |uniq -c |sort -n | tail -1000 | grep -v "0.0.0.0"

PM My skype voduy13 for support

You can try install CWP over sock proxy or something like that

I can install the vDDoS Proxy Protection after installing the CWP?
Problems will not be?
I did not quite understand how vDDoS works with nginx?
Should vDDoS listen on port 80? If so, how will the data be transferred from the vDDoS to the nginx configured on the non 80 port?
Is it possible to remove the vDDoS , if so, how?
Thank you!

1. vDDoS should be installed before installing other things (CWP, cPanel, VestaCP, LAMP, LEMP...)
(PS: But I try to install vDDoS after CWP is still successful-CentOS 7)

2. Nginx or Apache... running & listen on other-port /Example: 8080, 8443... Vddos listens at 80 and 443

3. Remove vDDoS:

Code: [Select]
vddos stop
rm -rf /usr/bin/vddos
rm -rf /vddos
rm -rf /usr/lib64/vddos/modules
rm -rf /var/log/vddos
rm -rf /var/cache/vddos

in https and centos 7 you must update nginx to 1.3 , becouse in nginx what to isntall not work openssl
Thanks for your report!



vDDoS 1.12.0 or 1.13.0 still working perfectly HTTP/2 with Openssl 1.0.2k https://www.openssl.org/source/old/1.0.2/ openssl-1.0.2l will be update soon

How to install with already installed cwp7 with apache and Nginx Reverse Proxy?

Thanks

You can change default port of nginx or stop & remove nginx (using only Apache+vDDoS)

Or install vDDoS in other-server
