Liferay Portal is one of the most flexible applications on the market today with regard to application server environments. It supports a wide variety of application servers, freeing you to use the Java application server you think is best. Liferay also scales very well: you can install Liferay Portal on everything from a shared hosting account to a multi-node cluster running a commercial application server and on everything in between. In fact, Liferay is used successfully in all of these scenarios every day.
You’ll find that because Liferay is extremely flexible in its deployment options, it is also easy to install. If you already have an application server, you can use the tools for deployment that came with your application server. If you don’t have an application server, Liferay provides several application server bundles from which to choose. These are pre-configured application servers with Liferay already installed in them. They’re very easy to install and with a small amount of configuration can be made into production-ready systems.
The installation steps vary slightly according to your Liferay edition, so we’ll be sure to let you know when they are different.
