Create file test.php file in folder controller.
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Test extends CI_Controller {
  public function __construct() {
    parent::__construct();
  }
  public function view($page = 'Test')
  {
    $this->load->helper('html');
    $this->load->helper('url');
    if ( ! file_exists(APPPATH.'views/fft/'.$page.'.php'))
    {
      show_404();
    }
    $data['title'] = $page; // Capitalize the first letter
    $this->load->view('fft/templates/pageheader',$data);
    $this->load->view('fft/'.$page, $data);
    $this->load->view('fft/templates/pagefooter');
  }
}
?>
At folder views, create folder fft.
application
--------bodymenu.php
--------pageheader.php
------test.php
We split file views->test.php. The other supporting files we put them into folder  [root codeigniter]->application->templates.
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
?>
<!-- banner -->
  <div data-vide-bg="<?php echo base_url(); ?>fft/video/sea">
    <div class="center-container">
      <div class="container">
        <!-- load body header -->
        <?php $this->load->view('fft/templates/bodyheader'); ?>
        <div class="logo animated wow zoomIn" data-wow-delay="900ms">
          <h1><a href="/web/joomla/index.html">Frequent <span>flyer</span><i>take me anywhere</i></a></h1>
        </div>
        <div class="start animated wow bounce" data-wow-delay="700ms">
          <a href="#about" class="hvr-bounce-to-bottom scroll">Get Started</a>
        </div>
      </div>
    </div>
  </div>
Final directory will like this:
[root codeigniter]
------views
------templates
--------bodyheader.php
--------pagefooter.php
------about.php
------test.php
--system
--userguide
--fft
----css
----fonts
----images

----video
----index.html
----w3layouts-License.txt

Install Composer in XAMPP 1.8.1 and Windows 10 (x64)

Prerequisites:

• Windows 10 
• XAMPP work

Make sure openssl extension is enable in php.ini:
extension=php_openssl.dll

Follow this step to install composer

1. Open cmd Windows
2. Donwload installer by running this command

   php -r "readfile('https://getcomposer.org/installer');" > composer-setup.php

   for example*

   D:\xampp\php>php -r "readfile('https://getcomposer.org/installer');" > composer-setup.php

3. Validate your composer-setup.php by running 

   php -r "if (hash_file('SHA384', 'composer-setup.php') === 'a52be7b8724e47499b039d53415953cc3d5b459b9d9c0308301f867921c19efc623b81dfef8fc2be194a5cf56945d223') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

   for example*:

   D:\xampp\php>php -r "if (hash_file('SHA384', 'composer-setup.php') === 'a52be7b8724e47499b039d53415953cc3d5b459b9d9c0308301f867921c19efc623b81dfef8fc2be194a5cf56945d223') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
   Installer verified

4. Install your composer by running

   php composer-setup.php

   for example*:

   D:\xampp\php>php composer-setup.php
   Some settings on your machine may cause stability issues with Composer.
   If you encounter issues, try to change the following:
   The OpenSSL library (0.9.8x) used by PHP does not support TLSv1.2 or TLSv1.1.
   If possible you should upgrade OpenSSL to version 1.0.1 or above.
   Downloading 1.0.3...
   Composer successfully installed to: D:\xampp\php\composer.phar
   Use it: php composer.phar

5. Remove composer-setup.php** by running:

   php -r "unlink('composer-setup.php');"

   for example*:

   D:\xampp\php>php -r "unlink('composer-setup.php');"

Note:
* in my case I use stand alone xampp in directory d:
** you do not have to save any composer-setup.php, it may change for a new version

WHM/CPanel Centos 7: enabling ipset in csf

Prerequisite:

• Iptables & Ipset
• Serverconfig v7.54 or later

Follow WHM/CPanel centos 7: blocking brute force attack to replace firewalld with iptables and ipset.

Download and Install serverconfig:

# wget http://configserver.com/free/csf.tgz# tar -xzf csf.tgz# cd csf & ./install.cpanel.sh

To enable ipset in csf, edit file /etc/csf/csf.conf or edit it via WHM/CPanel:

TESTING = “0”
LF_IPSET = 1
TCP_IN= “22,80,53,443” 
TCP_OUT=”22,80,53,443″
UDP_IN=”53″
UDP_OUT=”53″

NOTE: don't forget to add your port services

Restart your csf

# service csf restart

Or via WHM/CPanel click Restart CSF+LFD

WHM/CPanel Centos 7: blocking brute force attack

By default, Centos 7 use firewalld to manages net filter rules. Just like iptables, adding new rules may increase your cpu load. This is my notes to optimize net filtering ipset to block brute force attack.

Disable firewalld and enable iptables/ipset

Stop and mask the firewalld service:

# systemctl stop firewalld# systemctl mask firewalld

Install the iptables-services package:

# yum install iptables-services

Enable the service at boot-time:

# systemctl enable iptables
# systemctl enable ip6tables

Start iptables service

# systemctl start iptables
# systemctl start ip6tables

Install ipset

# yum install ipset

Install & Configure fail2ban (Optional)

Installing fail2ban

# yum install fail2ban

Enable fail2ban

# systemctl enable fail2ban

Start fail2ban

# systemctl start fail2ban

or

# service fail2ban start

Fix firewall run

# /scripts/configure_firewall_for_cpanel

Open some port for examples 12345

# iptables -I INPUT -p tcp --dport 12345 -m state --state NEW,ESTABLISHED -j ACCEPT

To disable fail2ban service

# systemctl stop firewalld
# systemctl disable fail2ban

If you prefered to use CSF (ConfigServer Sercurity & Firewall) follow WHM/CPanel Centos 7: enabling ipset in csf

Webmin: Domain Slave in webmin and Domain Master in WHM/CPanel

In WHM/Cpanel server:

• open file /etc/named.conf and edit

    //allow-transfer    { "none"; };
    allow-transfer { your_public_ip_for_slave_dns; }; 

• restart your bind/named

# /scripts/restartsrv_named 

In Debian Jessie server:

• Open webmin, Servers -> BIND DNS Server -> Create slave zone

Zone type : Forward (Names to Adddress)
Domain name / Network : yourdomain.com
Record file : Automatic
Master server : your_debian_ip_address
Server port : Default

• Test Zone Transfer

Testing transfer of slave zone from master_ip_address .... from master_ip_address : Completed OKTest transfer successfully fetched 28 records from at least one nameserver. Actual transfers by BIND should also succeed.

Now you can add/edit your Domain Slave Server in WHM/CPanel -> Edit DNS Zone.
