Learn how application servers are used in modern enterprise
environments and how to install IBM® WebSphere® Application
Server on UNIX® and Linux® systems to provide the cornerstone of a
robust, well-supported enterprise Web environment. This tutorial
also explains how to integrate WebSphere Application
Server into the startup and shutdown processes on your UNIX and
Linux servers and provides links to many other resources that will
help you get up and running quickly with WebSphere Application
Server.
In this tutorial
This tutorial provides:
-
A review of common Web architectures and the role of
application servers and middleware in today's enterprise Web
architectures.
-
A basic understanding of WebSphere Application
Server.
-
An overview and comparison of common WebSphere installation
and deployment mechanisms.
-
Instructions for installing WebSphere Application Server
on UNIX and Linux distributions.
-
A basic overview of the initial configuration of the WebSphere
Application Server.
-
Details on how to integrate WebSphere Application Server into
the system startup and shutdown processes and how to start and
stop the server manually.
Prerequisites
This tutorial is written for beginning to intermediate-level
systems administrators who may never have installed or
configured a Web application server and who may be unfamiliar
with modern Web server architectures. To complete the examples
in this tutorial, you should have a general familiarity with
UNIX command-line shells and text editors.
System requirements
To run the examples in this tutorial, you need administrative
(root) privileges on a UNIX or Linux system on
which no application server is currently installed. The system
should have a minimum of 1GB of RAM.
When installing WebSphere Application Server, at least 3.1GB
of disk space must be available on the system: A minimum of
1.3GB must be permanently available in the file system that
contains the /opt directory, and 1.75GB more must be temporarily
available in the file system from which you install WebSphere Application Server.
If you are installing WebSphere Application Server on a
Linux system, not all Linux distributions include a version
of the Java™ Runtime Environment (JRE) that is suitable for use by the installer and certain
WebSphere Application Server functions. On unsupported Linux
distributions such as Ubuntu, you should download and install the IBM
Java software development kit (SDK) and make some minor modifications to your system before
installing WebSphere Application Server. See Setting up unsupported Linux distributions for instructions.
If you choose to install the IBM Java SDK, at least 450MB of
additional disk space must be available on the system: A minimum
of 175MB must be permanently available in the file system that
contains the /opt directory, and 275MB more must be temporarily
available in the file system from which you install IBM Java
SDK.
To view the demos included in this tutorial, JavaScript must be enabled in your browser and Macromedia Flash Player 6 or higher must be installed. You can download the latest Flash Player at http://www.macromedia.com/go/getflashplayer/.

About this tutorial
Application servers are a central component of the Web
architectures used in enterprise computing today. This tutorial
begins with a general discussion of middleware in today's Web
architectures, focusing on IBM's WebSphere family of products
and the different ways in which WebSphere Application Server can
be deployed. The remainder of the tutorial provides detailed
information about how to install and configure WebSphere
Application Server, integrate it into your system's startup
process, and integrate it into your enterprise computing
infrastructure. After completing this tutorial, you will
understand how to install, configure, and deploy WebSphere
Application Server and its relationship with other applications
and servers in a Web-based computing environment.
