Taarifa Platform

The Taarifa Platform is an open source web application for information collection, vizualisation and interactive mapping. It allows people to collect and share their own stories using various mediums such as SMS, Web Forms, Email or Twitter, placing these reports into a workflow. For more information about the platform and use cases (case studies) visit: http://www.taarifa.org

System Requirements

To install the platform on your computer/server, the target system must meet the following requirements:

PHP version 5.2.3 or greater
MySQL version 5.0 or greater
An HTTP Server. Kohana, which Ushahidi is built on, is known to work with the following web servers:
- Apache 1.3+
- Apache2.0+
- lighttpd
- Microsoft Internet Information Server (MS IIS)
Unicode support in the operating system

Required Extensions

The follwing is a list of PHP extensions that must be installed on your server in order for Taarife to run properly:

PCRE (http://php.net/pcre) must be compiled with –enable-utf8 and –enable-unicode-properties for UTF-8 functions to work properly.
iconv (http://php.net/iconv) is required for UTF-8 transliteration.
mcrypt (http://php.net/mcrypt) is required for encryption.
SPL (http://php.net/spl) is required for several core libraries
mbstring (http://php.net/mbstring) which speeds up Kohana's UTF-8 functions.
cURL (http://php.net/curl) which is used to access remote sites.
MySQL (http://php.net/mysql) is required for database access.

#####NOTE: Need to figure out what extensions you already have installed on your server? Here are instructions to do just that: http://jontangerine.com/silo/php/phpinfo/

Optional Server Requirements

To use Taarifa's "Clean URLS" feature on an Apache Web Server, you will need the mod_rewrite module and the ability to use local .htaccess files. To check if local .htaccess files are allowed, verify that the "AllowOverride" directive in your Apache config (for the web server directory in which you have installed Taarifa) has been set to "All" i.e.:
```
  <Directory [your-document-root-directory]>
      ...
      AllowOverride All
      ...
  </Directory>
```

#####NOTE: Clean URLs means that the URLs of your deployment will not have the 'index.php' prefix

Installation

####Download and extract Taarifa

To unzip/extract the archive on a typical Unix/Linux command line:
```
  tar -xvf Taarifa_Web-xxxx.tar.gz
```
or in the case of a zip file:
```
  unzip Taarifa_Web-xxxx.zip
```
This will create a new directory Ushahidi_Web-xxxx containing all the Ushahidi platform files and directories - Move the contents of this directory into a directory within your webserver's document root or your public HTML directory.
####Ensure the following directories are writable (i.e. have their permission values set to 777)
- application/config/config.php
- application/config
- application/cache
- application/logs
- media/uploads
- .htaccess
On Unix/Linux, you can change the permissions as follows:
```
  cd path-to-webserver-document-root-directory
  chmod -R 777 application/config
  chmod -R 777 application/cache
  chmod -R 777 application/logs
  chmod -R 777 media/uploads
  chmod 777 .htaccess
```
#####NOTE: The process of configuring file permissions is different for various operating systems. Here are some helpful links about permissions for the Windows (http://support.microsoft.com/kb/308419) and Unix (http://www.washington.edu/computing/unix/permissions.html) operating systems.
####Create the Ushahidi database Ushahidi stores all its information in a database. You must therefore create this database in order to install Ushahidi. This is done as follows:
```
  mysqladmin -u 'username' -p create 'databasename'
```
MySQL will prompt for the password for the database password and then create the initial database files. Next, you must log in and set the database access rights:
```
  mysql -u 'username' -p
```
Again, you will be prompted for the 'username' database password. At the MySQL prompt, enter the following command:
```
  GRANT SELECT, INSERT, DELETE, UPDATE, CREATE, DROP, ALTER, INDEX on 'databasename'.* 
  TO 'username'@'localhost' IDENTIFIED BY 'password';
```
Where:
- 'databasename' is the name of your database
- 'username@localhost' is the name of your MySQL account
- 'password' is the password required for that username
#####NOTE: Your account must have all the privileges listed above in order to run Ushahidi on your webserver.
####Run the install script To run the install script, point your browser to the base url of your website: (e.g. http://www.example.com).

You will be guided through a series of screens to set up the database and site settings depending on the installation method you choose (Basic or Advanced)
