Ubuntu 12.04, LAMP and CodeIgniter 2

This guide aims to install and use CodeIgniter on an Ubuntu machine. We will assume you have the default Ubuntu installation.

1. Install Apache 2:

   sudo apt-get install apache2

2. Install MySQL:
   

   sudo apt-get install mysql-server mysql-client

3. Install PHP5 and the necessary libraries:
   

   sudo apt-get install php5-cli php5-mysql libapache2-mod-php5

4. Download the CodeIgniter framework:
   

   wget http://codeigniter.com/download.php -O ~/CodeIgniter.zip

5. Extract the framework to the default Apache2 web directory:
   

   sudo unzip ~/CodeIgniter.zip /var/www/

6. You should now be able to navigate to your extracted folder from your web-browser. Hint: you will need to open firefox to http://localhost/<name-of-folder> which you can get by executing the following command:
   

   ls /var/www
