Steps to install CSF firewall on your Centos Linux Server

Step 1:
Make sure perl modules are installed.
yum install -y perl-libwww-perl

Step 2:
Download, unpack the tar file.
Download from the link :  http://www.configserver.com/cp/csf.html

Commands to be used:

cd /usr/local/src
wget http://www.configserver.com/free/csf.tgz
tar -zxvf csf.tgz
cd csf
./install.sh

Step 3:

Edit the configuration with your favorite editor, in this case I used vi:

vi /etc/csf/csf.conf 

Edit the value from: 

TESTING = "1"

to => TESTING = "0"

Step 4: Restart the service:

/etc/init.d/csf restart
