9.8. Installing Cartridges
At this point, install any web or add-on cartridge packages for your OpenShift Enterprise deployment.
Web cartridges provide support for specific types of applications to run on OpenShift Enterprise. For example, there is a web cartridge that supports PHP development, and another for Ruby development.
Add-on cartridges include database and management cartridges, and exist to support additional functions on which an application may rely. For example, cartridges exist for the MySQL and PostgreSQL database servers.
If a particular cartridge is not installed at this point, it can be installed later. However, a cartridge must be installed before developers can create applications for the supported framework or service.
Important
Administrators choose the set of installed cartridges. However, node hosts require installation of this same set on each node host. Gear placement does not currently take into account differences in the installed cartridges per node host. All node hosts are assumed to have the same cartridge set, and gear creation fails on a node host that is missing cartridges required for the gear.

If needed, administrators can choose to configure the JBoss EWS cartridge tomcat7 binary provided by the EWS 3 product to work around known security issues with the JBoss EWS-2 tomcat7 binary. See Known Issues to learn more.
