Sun Java System Web Server 7.0 Update 8 Installation and Migration Guide

Chapter 1 Installation Overview

This chapter provides an overview of Sun Java System Web Server 7.0 (also referred to as Web Server) installation. For detailed installation instructions, see Chapter 2, Installing the Web Server.


Note –

Sun Java System Web Server can be purchased by itself (stand-alone) or as a component of Sun JavaTM Enterprise System (Java ES). This guide describes how to install the stand-alone Web Server. For information about installing Web Server as a component of Java ES or about upgrading Web Server from a previous Java ES release, refer to the Java ES system documentation at http://docs.sun.com/app/docs/prod/entsys#hic.


This chapter contains the following sections:

Installation Enhancements and Changes

This section provides a brief list of the major installation-related enhancements and changes in Web Server 7.0. For complete information about new features in this release, see the Sun Java System Web Server 7.0 Update 8 Release Notes.

Web Server 7.0 provides the following features:

New Administration Framework

Sun Java System Web Server 7.0 includes a new administration framework that provides enhanced distributed management across servers in a server farm. Robust administration capabilities enable Web Server configurations to be managed and deployed remotely using both graphical and command-line interfaces. Server configurations can be managed on a central location in a server farm and distributed to one or more nodes to create server instances. Monitoring and lifecycle management of these server instances are also provided.

Server farms, clusters, and this new administration framework are described in detail in the Sun Java System Web Server 7.0 Update 8 Administrator’s Guide, but a general understanding of related terms will be helpful as you perform the installation:


Note –

It is important to note the distinction between a configuration and an instance. In Web Server 7.0, a server instance is created by deploying a configuration to one or more nodes in a server farm. A configuration is a virtual representation of an instance.


Web Server Components

During installation you will make choices about the Web Server components to be installed. In general, these choices are based on the role the server will play in a server farm environment and on other administration considerations. Component choices are made only if you are performing a Custom installation. For Express installations, default components are installed automatically, as listed in Table 2–2. Web Server 7.0 includes the following components:


Note –

You can install the administration command-line interface without installing server core, but you cannot install server core without installing the administration command-line interface.


Server Core

Server core refers to the core binaries required for the Web Server environment. If Server Core is selected, an Administration instance is created and it can be configured as either the Administration Server or the Administration Node, both of which are described below. If the Administration instance is configured as Administration Server, a default Web Server instance is installed. These installation options are used in server farm environments in which a centralized Administration Server resides on one of the nodes and Administration Nodes reside on the rest.

When considering the options described above, use the following general guidelines:

Server Core 64–bit Binaries (Solaris SPARC, AMD64, Linux Only)

If this option is selected, the 64–bit binaries required for setting up the 64–bit runtime for the default Web Server instance are installed. This option is selected by default and displays only if the system on which you are installing has 64-bit support. If this option is selected, both 64- and 32-bit binaries are installed. For more information about 64-bit support in Web Server 7.0, see 64-bit Support.

Administration Command-Line Interface

If you specify Administration Command-Line Interface in the component selection portion of the installation, just the command-line administration interface is installed. This tool is used to administer and configure all Administration Server and Web Server instances in a server farm remotely from the command line. For detailed information about the command-line tool and the powerful new command-line administration interface, see the Web Server 7.0 CLI Man Pages document. For basic information that will help you get started, also see Using the Administration Command-Line Interface in this document.


Note –

You can install the administration command-line interface without installing server core, but you cannot install server core without installing the administration command-line interface.


Sample Applications

If you select Sample Applications in the component selection portion of the installation, sample applications demonstrating Web Server features and functionality are installed. The default installation location is install_dir/samples. For more information about the sample applications, see Sample Applications in Web Server 7.0 in Sun Java System Web Server 7.0 Update 8 Developer’s Guide to Java Web Applications.

64-bit Support

Web Server 7.0 provides the option of installing a 64-bit version of the Web Server on Solaris SPARC and Solaris AMD64. If the installer detects a 64-bit system, you have the option to install the 64-bit binaries. This option is available only for the following platforms:

Also note the following considerations:

Directory Structure

For detailed information about the directory structure created when you first install the Web Server, see the Sun Java System Web Server 7.0 Update 8 Administrator’s Configuration File Reference.
