Introduction

1. Overview of This Release

Red Hat Application Stack is a set of software components that have been tested and certified

to work together in an integrated fashion. Red Hat Application Stack is designed for dynamic

web applications for both the LAMP and Java (TM) platforms.

2. Installation Prerequisites

• Red Hat Application Stack V.2.1 has been tested and certified on Red Hat Enterprise Linux 5

systems. It is not certified for use with earlier versions of Red Hat Enterprise Linux. Please

follow the separate instructions for installing Red Hat Enterprise Linux 5 before installing Red

Hat Application Stack V.2.1.

• Red Hat Application Stack V.2.1 is available for 32- and 64-bit Intel architectures only (i386

and x86_64).

• Red Hat Application Stack V.2.1 includes JBoss Enterprise Application Platform 4.2, for

running web applications in a standard middleware environment. Note that the JBoss

Enterprise Application Platform uses an embedded Tomcat and does not require a

stand-alone Tomcat. Before installing and running the JBoss Application Server (the

application server component of JBoss Enterprise Application Platform 4.2), you will require a

working installation of Java 1.5. Currently Red Hat Application Stack is certified with the Sun

JVM 1.5.0 update 15 or later, and the latest BEA JVM available through RHN. Please refer to

Chapter 2, Configuring the Java Environment for instructions on configuring the Java

environment for JBoss Application Server.

• If you intend to use the production config (started by default), you will need atleast 1.5GB of

physical memory.

3. Package-specific Notes

In most cases, Red Hat Application Stack contains more recent versions of packages than

those that are included in Red Hat Enterprise Linux. Installing Red Hat Application Stack may

update/overwrite these packages. Please ensure you review the complete package list before

beginning the installation process.

Chapter 1.

Configuring the Java Environment

JBoss Application Server relies on an installed JVM, such as those by Sun, or BEA. Both JVMs

are available from the Red Hat Enterprise Linux 5 Supplementary channels.

THIS RELEASE HAS BEEN CERTIFIED WITH THE SUN

AND BEA JVMS.

Currently Red Hat Application Stack is certified with the Sun JVM version 1.5.0

update 15 or later and the latest BEA JVM available through RHN. This may

change in future releases.

With Red Hat Enterprise Linux 5 there are 1.5 versions of the BEA (JRockit), IBM and SUN

SDKs.

We have adopted the jpackage.org style for the packaging of our Java offerings. This requires

that the jpackage-utils rpm be installed on your system. A JPackage-style JVM must be

installed via yum (see channel details below) and jpackage-utils will be automatically brought

in as a dependency.

1. Install a supported SDK

1.1. Installing a BEA, IBM or Sun SDK

1. Install a Java SDK from RHN

Java SDKs are provided by the Red Hat Enterprise Linux 5 Supplementary channel for your

Linux variant and architecture. Depending on the architecture, the channel names are:

rhel-i386-server-supplementary-5 and rhel-x86_64-server-supplementary-5

The java-1.5.0-bea,java-1.5.0-ibm and java-1.5.0-sun SDKs are available from these

channels. Make sure you also install the -devel subpackages.

2. Selecting alternatives for java,javac and java_sdk_1.5.0 (setting java_sdk_1.5.0 is

optional).

This is only needed if you want to use the SysV service script and/or want this installed SDK

to be the default java and javac in the system. This choice can often be overridden by setting

the JAVA_HOME environment variable.

The alternatives system allows different versions of Java, from different sources to

co-exist on your system. You should make sure the desired one is selected so that the

service script uses the one you want.

Chapter 2.

As root, issue the following command:

/usr/sbin/alternatives --config java

and make sure the desired one is selected (marked with a '+'), or select it by entering its

number as prompted.

Make sure you do the same for javac and java_sdk_1.5.0. We recommend that all point to

the same manufacturer and version.

2. Install the jbossas package

2.1. Using yum / RHN (Preferred Method)

1. Update your Red Hat Enterprise Linux 5 installation and install the JVM as described above.

2. Subscribe to the Enterprise Application Platform child channel:

e.g: jbappplatform-4-i386-as-5-rpm or jbappplatform-4-x86_64-as-5-rpm

3. Install JBoss Application Server:

• For the Application Server (which includes an embedded Tomcat), run:

yum install jbossas

Refer also to Chapter 4, Using JBoss Application Server below.

2.2. Using yum / DVD

To install using yum / DVD:

1. Update your installation and install the JVM as described above.

2. Mount the Red Hat Application Stack V.2.1 DVD.

3. Create a new file in /etc/yum.repos.d/ with the following contents to update directly from

the RPMs on the disk:

[stacksv2]

name=Red Hat App Stack

baseurl=file:///path/to/mounted/DVD/Stacks/
