   1. What server does Sentrifugo work on? ======================================= Sentrifugo works only on Apache Server

   2. Windows Installation Guide ============================= AMP stack for Windows

      • The recommended AMP stack for Windows is XAMPP (Download the installer from basic package)
      • The system installer for XAMPP will guide you through the installation process

      Copying files

      • Move Sentrifugo zip file into the document root of Apache HTTP server.
      • If you used XAMPP for windows, document root is \htdocs\
      • For example: C:\xampp\htdocs\

      Extracting

      • Extract the Sentrifugo zip file in the document root of Apache HTTP server

      Web Installer

      • XAMPP users; the AMP stack for Windows needs to be started manually.
      • Using a JavaScript enabled browser go to http:///sentrifugo/; Where is localhost if it is installed in the machine you are currently working on, IP address if it is remotely hosted

      Pre-requisites

      The system requirements for installing Sentrifugo are described below. Make sure your system meets these requirements.

      a. PHP 5.3 or later You can download PHP 5.3 or later by visiting http://windows.php.net/download/

      b. PDO MySQL (for MySQL connection) To install Sentrifugo on windows, you need to enable the PDO and PDO_MYSQL extensions in your php.ini file. You can add the following lines in your php.ini file:

       1. extension=php_pdo.dll
       2. extension=php_pdo_mysql.dll
      

      c. Rewrite module (for working of MVC architecture) To activate the module, the following line in httpd.conf needs to be uncommented:

       1. LoadModule rewrite_module modules/mod_rewrite.so
       To see whether it is already active, try putting a .htaccess file into a web directory containing the line
      
       2. RewriteEngine on
       If this works without throwing a 500 internal server error, and the .htaccess file gets parsed, URL rewriting works.
      
       You also need to make sure that in your httpd.conf, AllowOverrides is enabled:
      
       3. AllowOverride all
       This is important as many httpd.conf ship by default with allowoverride none
      

      d. GD library (for images) You can add the following lines in your php.ini file:

       1. extension = php_gd2.dll
      

      e. Open SSL (For SSL and TSL Protocols) Download the installer for OpenSSL 1.0.1e from http://www.openssl.org/related/binaries.html

       If OpenSSL is already installed in your system, to enable this extension in your php.ini file, you can add the following line in your php.ini
       file:
      
       1. extension=php_openssl.dll
      

   3. Linux Installation Guide =========================== AMP stack for Linux

      • The recommended AMP stack for Linux is XAMPP Linux 1.6 (Download the complete stack and not the upgrades)
      • The system installer for XAMPP in the XAMPP site will guide you through the installation process
      • Start the stack manually every time you reboot.
      • Change the ownership of Sentrifugo files (Ex: /opt/xampp/htdocs/sentrifugo/ $ chown -R nobody.nobody)

      Copying files

      • Move Sentrifugo zip file into the document root of Apache HTTP server.
      • If you used XAMPP for windows, document root is \htdocs\
