Preparing for Installation

The installation process is easy and straightforward; however, it is essential that you verify all requirements before you install Sun Ray Server Software 3. This chapter describes what you need to do.

Topics in this chapter include:

Hardware Requirements

Software Requirements

Before you install Sun Ray Server Software, you should:

Verify the operating environment -- Make sure that you are running the desired supported operating system on your system.

Verify that you have installed the latest operating system updates patches.

Verify system requirements -- Make sure that the system(s) on which you plan to install the software fulfills the necessary hardware and software requirements.

Hardware Requirements

Disk Space

Note - The suggested server configuration includes approximately 50-100 MB of swap space per user.

The standard installation of Sun Ray Server Software requires at least 95 MB of disk space. TABLE 2-1 lists the disk space requirements for specific directories:

TABLE 2-1 Sun Ray Server Software Disk Space Requirements
Product	Default Installation Path	Requirements
Sun Ray core software	`/` `/opt` `/var/log` `/var/tmp` /var/opt/SUNWut	1 Mbyte 20 Mbytes 1 Mbyte 5 Mbytes Allow enough disk space for the log files.
Sun Ray Data Store 2.0	`/opt/SUNWut/srds` `/etc/opt` `/var/opt/SUNWut/srds`	4 Mbytes in `/opt` 0.1 Mbytes in `/etc` Allow enough disk space for the database and log files. For 1,000 entries, allocate roughly 1.5 Mbytes of disk space, 64 Mbytes of RAM, and 128 Mbytes of swap space.
JRE 1.4.2 or later		60 Mbytes
English docs (optional)	`/opt`	8.5 Mbytes
English docs (optional)	`/opt`	8.5 Mbytes
Non-English docs (optional)	/opt	8.5 Mbytes for each locale

Software Requirements

Java Runtime Environment (JRE)

SRSS 3 requires JRE version 1.4.2 or later. The latest Java release is available at:

http://java.sun.com/j2se

JRE version 1.4.2 is also bundled on the SRSS 3 CD, in the Supplemental directory.

Linux Operating System Versions

Sun Ray Server Software 3 runs on:

Sun Java Desktop System (JDS) Release 2

SuSE Linux Enterprise Server (SLES) 8.0, at the SP3 (Service Pack 3) level or later

Red Hat Enterprise Linux Advanced Server (RHEL AS) 3.0

Java Desktop System Release 2

JDS requires that all packages be installed, including:

dhcp-base-3.0.1rc9-111.i586.rpm

dhcp-server-3.0.1rc9-111.i586.rpm

openmotif-2.2.2-502.i586.rpm

pax-3.0-219.i586.rpm

perl-XML-Parser-2.31-216.i586.rpm

tftp-0.29-105.i586.rpm

To make sure these RPMs are installed during JDS installation:

1. Select Detailed Selection in Software Selection screen

2. Select Add-on packages, Ice WM Desktop, Development Tools

3. Select Package groups followed by Development -> Libraries -> Perl, then select perl-XML-Parser from the right side panel.

4. Select Package groups followed by Productivity -> Archiving, then select pax from the right side panel.

5. Select Package groups followed by Productivity -> Networking, then select dhcp-base, dhcp-server, and tftp from the right side panel.

If you want to enable telnet then also select telnet, telnet-server.

6. Select Package groups followed by System, then select openmotif from the right side panel.

After completing the JDS installation, install pdksh-5.2.14-531.i586.rpm, which is available at:

ftp://rpmfind.net/linux/SuSE-Linux/i386/8.1/suse/i586/pdksh-5.2.14-531.i586.rpm

SuSE Linux Enterprise Server (SLES) 8.0

All packages are required and must be installed. During installation, select Detailed Selection from the Software Selection screen, then select all check boxes for Package Selection.

Note - In addition, Service Pack 3 or later must be installed.

RPMs freetype2-2.9-87 and freetype2-devel-2.0.9.87 must be replaced with the latest versions, freetype2-2.1.3-49.i586.rpm and
freetype2-devel-2.1.3-49.i586.rpm, which are available in the SRSS 3 Supplemental directory.

Please use the following procedures:

1. To remove the old RPMs:

# rpm -e --nodeps freetype2-2.0.9.87

# rpm -e --nodeps freetype2-devel-2.0.9087

2. To install the correct RPMs:

# rpm -i freetype2-2.1.3-49.i586.rpm

# rpm -i freetype2-devel-2.1.3-49.i586.rpm

Red Hat Enterprise Linux Advanced Server (RHEL AS) 3.0

All packages are required, so it is best to configure the Sun Ray Server on a system on which all packages of RHEL AS 3.0 are installed.

During installation, select the Customize option, then select the check box for Everything in the Package Selection panel.

Caution - The Red Hat installation script asks whether to start a graphical console. Be sure to answer "Yes", otherwise Sun Ray startup scripts and X initialization scripts may fail to run.

Sun Ray Administration Tool

The Sun Ray Administration Tool (Admin GUI) requires that an Apache HTTP Server be installed and running on each Sun Ray Server.

If an Apache HTTP Server is detected, the utconfig script asks whether it should be configured automatically. If you answer Yes, then it is so configured.

If you answer No, then the configuration is stored in /etc/opt/SUNWut/http/http.conf. You can then use this file to configure the HTTP server manually. If you want to use a web server other than Apache, see To Configure an HTTP Server Manually.

Note - The Apache HTTP Server is installed automatically when you follow the instructions above for Red Hat Enterprise Linux Advanced Server and SuSE Linux Enterprise Server 8. JDS requires manual installation of the Apache HTTP Server. See To Configure an HTTP Server Manually.

The Apache HTTP Server is available at the following URL:
http://httpd.apache.org

The Sun Ray configuration script uses port 1660 for the Sun Ray Administration Tool (Admin GUI) by default. If this port is unavailable, you can configure a new port while running the utconfig script.

For information on configuring a web server manually, see To Configure an HTTP Server Manually.

Sun Ray Port Requirements

When you configure a SRSS 3 server in a failover environment, service port 7012 is used by default.

Sun Ray Data Store

If you already have an LDAP (Lightweight Data Access Protocol) server configured on the Sun Ray server, it can coexist with Sun Ray Data Store; however, it must not use port 7012, which is reserved for use by the Sun Ray Data Store.

Web Browser Requirements

To view the Sun Ray Administration Tool (Admin GUI), you must have a web browser, such as Mozilla or Netscape trademark Communicator, installed on the system that will display it.

The latest version of the Mozilla browser is available at:

http://www.mozilla.org/download.html

The latest version of the Netscape Communicator web browser is available at:

http://www.netscape.com/download

For instructions on manual configuration of a web server, see To Configure an HTTP Server Manually.
