Caution

There is currently no check for sufficient disk space and no undo procedure. Total disk space required to install all software on the CD is 650 MB.

On UNIX, the script determines if GUI mode will be used based upon the DISPLAY environment variable; if it is set, the script uses the GUI, if it is not, it will run in text mode. This allows the installation to work graphically from a remote computer (such as installation from a UNIX workstation via Telnet to a server in a machine room), or non-graphically (running in the Telnet window). If you are operating remotely or as a superuser “sulogged-in to root from another user, make sure the access control has been disabled as required (using xhost).

Text and graphical installation modes both ask for exactly the same data. However, a Windows NT installation only prompts for information regarding supported features and prompts for less. Also, Windows NT only supports the graphical installation mode.

To determine the current user in a UNIX environment, the script looks at two environment variables. If USER is set, it is referenced for root/non-root permission. If USER is not set, LOGNAME is used in the same manner. This is because Openserver uses USER when logged in via X and LOGNAME when logged in through the text mode console.

After completing the worksheets (Appendix B) and determining the topology of your server environment, you will need to install the CD in the CD-ROM drive on your machine and mount the drive. For the same configuration as for the terminal test environments, the CD-ROM drive is as follows (by platform):

Platform

Drive

SCO UnixWare

/dev/cdrom/c0b0t510

SCO OpenServer

/dev/cd0

Slackware Linux

/dev/cdrom

Red Hat Linux

/dev/cdrom

HP/UX

/dev/c1t2d0

This may be different for your configuration. Consult your manual. For the purpose of describing the procedure, it is assumed the CD-ROM is mounted on a directory named /cdrom. Again, if you mount it somewhere else, make the appropriate interpretive changes as you go through this document.
