[Version 5.0.2 and later]Installing the product

This topic describes how to install WebSphere Application Server products as the root user on a Linux platform or on a UNIX-based platform, or from a user ID that belongs to the administrator group on a Windows platform.

Before you begin

You cannot install the product correctly as a non-root user on a Linux or UNIX-based operating system platform, or from a user ID on a Windows platform that is not part of the administrators group. If you back up the product CD-ROM on a Linux or UNIX platform, do so as root. Backup copies made from non-root users do not preserve the correct file attributes and do not work.

In addition, Linux and UNIX installers must verify that the umask setting is 022. To verify the umask setting, issue the following command:

umask

To set the umask setting to 022, issue the following command:

umask 022

Linux platforms and Solaris operating environments

On Linux platforms or Solaris operating environments, make sure that the /etc directory contains a shadow password file. The shadow password file is named shadow and is in the /etc directory. If the shadow password file does not exist, an error occurs after enabling global security and configuring the user registry as local operating system.

To create the shadow file, run the pwconv command (with no parameters). This command creates an /etc/shadow file from the /etc/passwd file. After creating the shadow file, you can configure local operating system security.

Some steps of the installation procedure on a Windows platform require the user to belong to the administrator group and have the following advanced user rights, Act as part of the operating system and Log on as a service.

IBM Support offers tutorials on various WebSphere Application Server installation topics. See WebSphere education on demand: Installation best practices tutorials for more information. One topic describes installing new or coexisting versions.

Read through this topic and its related topics to prepare for installation and to make yourself familiar with installation options, before you start to use the installation tools.

Review the prerequisite requirements on the WebSphere Application Server detailed system requirements Web site to get started.

After verifying prerequisites, read these topics before installing the product:

If you encounter a problem such as not having enough disk space or temporary space or not having prerequisite packages on your Linux or UNIX-based system, cancel the installation, make the required changes, and restart the installation to pick up the changes that you made.

The installation uses InstallShield for Multiplatforms (ISMP) to perform the installation. You can use the Installation wizard or perform the installation from a command line, using the silent installation method.

The Installation wizard does not support hot keys, such as Alt-Y. You can tab to the Yes key and press Enter to select it, for example.

Although you can create multiple servers on a base WebSphere Application Server node, the servers all share one set of configuration files. Changes that you make to one server affect the others. There is a possibility that configuration documents might become corrupted. Use configuration instances to create multiple servers, each with its own set of configuration files. Or install the Network Deployment product to create and manage multiple base Application Servers.

Install the base product before installing the Network Deployment product when installing both products on the same machine. The embedded messaging feature that is included in the default installation requires this specific order of installation.

This topic describes installing the Network Deployment product, using the installation image on the product CD-ROM labeled, Deployment Manager. Use a CD-ROM labeled, Application Server, IBM HTTP Server, in the Network Deployment product package to install the base WebSphere Application Server product. Open this topic in the information center for the base WebSphere Application Server product to learn how to install the base WebSphere Application Server product.

[5.0 only]The Deployment Manager CD-ROM is available in both the Network Deployment product package and the Enterprise product package. Use this information center topic to install the Network Deployment product, regardless of which package the CD-ROM comes from. Open this topic in the information center for the Enterprise product to learn how to install the Enterprise product and extend the multimachine environment. The CD-ROM for the Enterprise product is labeled, Enterprise Application Server.

This topic is available in Adobe PDF format, on the product CD-ROMs, and online in an information center that is available from the IBM WebSphere Application Server Web site at http://publib.boulder.ibm.com/infocenter/ws51help/index.jsp . When possible, access the most current version of this information by selecting the information center. The information center displays in the language of your machine locale.
