CodeIgniter on OpenShift

The easiest way to install this application is to use the OpenShift Instant Application. If you'd like to install it manually, follow these directions.

OpenShift Considerations

These are some special considerations you may need to keep in mind when running your application on OpenShift.

Database

By default, your application is configured to use a MySQL database on OpenShift.

Handling Multiple Environments

By default, CodeIgniter on OpenShift comes with the ENVIRONMENT constant set to 'production'. At the top of php/index.php, you will see:

define('ENVIRONMENT', 'production');

In production mode, your application will:

• Disable all error output (for security reasons)

When you develop your CodeIgniter application locally, you can change the environment by setting the ENVIRONMENT variable in php/index.php to 'development':

define('ENVIRONMENT', 'development');

If you do so, CodeIgniter will run your application under 'development' mode. In development mode, your application will:

• Show more detailed errors in browser
• Load development-specific configuration files

We strong advise you to not run your application in this mode in production.

Visit the CodeIgniter User Guide for more details on using multiple CodeIgniter development environments.
