Installation Instructions¶

+

CodeIgniter is installed in four steps:

+

Unzip the package.
Upload the CodeIgniter folders and files to your server. Normally the +index.php file will be at your root.
Open the application/config/config.php file with a text editor and +set your base URL. If you intend to use encryption or sessions, set +your encryption key.
If you intend to use a database, open the +application/config/database.php file with a text editor and set your +database settings.

+

If you wish to increase security by hiding the location of your +CodeIgniter files you can rename the system and application folders to +something more private. If you do rename them, you must open your main +index.php file and set the $system_path and $application_folder +variables at the top of the file with the new name you’ve chosen.

+

For the best security, both the system and any application folders +should be placed above web root so that they are not directly accessible +via a browser. By default, .htaccess files are included in each folder +to help prevent direct access, but it is best to remove them from public +access entirely in case the web server configuration changes or doesn’t +abide by the .htaccess.

+

If you would like to keep your views public it is also possible to move +the views folder out of your application folder.

+

After moving them, open your main index.php file and set the +$system_path, $application_folder and $view_folder variables, +preferably with a full path, e.g. ‘/www/MyUser/system’.

+

One additional measure to take in production environments is to disable +PHP error reporting and any other development-only functionality. In +CodeIgniter, this can be done by setting the ENVIRONMENT constant, which +is more fully described on the security +page.

+

That’s it!
