Preparation

Always make sure that the root of apache is in the folder /var/www/ and NOT the /var/www/html
In this case, the system was in /var/www/cloud_lab
The below has been tested on Ubuntu14 with Apache/2.4.7
1) In order to make it work, you have to remove the ‘index.php’ from the url
Edit the file config/config.php:
change from $config['index'] ='index.php' –to-> $config['index'] = ''; 2) Enable a2enmod:
sudo a2enmod rewrite 3) Edit the apache configuration sudo vim /etc/apache2/apache2.conf
Within <Directory /var/www/>
change from AllowOverride None –to-> AllowOverride All 4) create an .htaccess file in the root directory of the project with the following code:

<IfModule mod_rewrite.c>
    RewriteEngine On  
    RewriteBase /cloud_lab/  # 	this is the name of the subdirectory for our case
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

(For Apache 2.2.22):

sudo vim /etc/apache2/sites-enabled/000-default

and then change in ‘/var/www/’ to:

 <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
 </Directory>

5) Restart apache:
sudo service apache2 restart

First part of the cloud_lab

It is developed in Codeigniter. The aim is to create a system that allows the sharing of general information such as the available labs and the user profiles. Users will be allowed to save their code, make it available to the public or keep it private.

Second part of the cloud_lab

To develop the RESTFul interface of the labs in order to accept and execute arduino code. It is not written yet but it wil be on a different language, perhaps GO or NodeJS.
