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 platforms.

2. Installation Prerequisites

• Red Hat Application Stack V.1.3 has been tested and certified on Red Hat Enterprise Linux 4

U5 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 4 before installing Red

Hat Application Stack V.1.3.

• Red Hat Application Stack V.1.3 is available for 32- and 64-bit Intel architectures only (i386

and x86_64).

• Red Hat Application Stack V.1.3 includes JBoss AS 4.2, for running web applications in a

standard middleware environment. Note that JBoss AS uses an embedded Tomcat and does

not require a stand-alone Tomcat. Before installing and running JBoss AS 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 AS.

• 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 AS relies on an installed JVM, such as those by Sun, or BEA. Both JVMs are available

from the Red Hat Enterprise Linux (AS/ES) Extras channel.

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 4 U6 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(TM) offerings. This

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

be installed via up2date (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 4 Extras channel for your Linux

variant and architecture. The channel names are as follows:

rhel-arch-variant-4-extras

where:

arch = i386 or x86_64 variant = as, or es

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.

Chapter 2.

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.

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 up2date / RHN (Preferred Method)

1. up2date your RHEL4 installation and install the JVM as described above.

2. Subscribe to the Enterprise Application Platform child channel:

For example: jbappplatform-4-i386-as-4-rpm or jbappplatform-4-x86_64-as-4-rpm

3. Install JBoss AS:

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

up2date jbossas

Refer also to Chapter 4, Using JBoss AS below.

2.2. Using up2date / DVD

To install using up2date / DVD:

1. up2date your installation and install the JVM as described above.

2. Mount the Red Hat Application Stack V.1.3 DVD.

3. Add the following line to /etc/sysconfig/rhn/sources to use up2date directly on the

RPMs on the disk:

dir RedHat-Application-Stack-V1 path_to_mounted_DVD/RedHat/RPMS
