Preparing for Installation [2]
Before you install CrayDoc, think carefully about the environment in which you
intend to use the CrayDoc system.
CrayDoc requires the Apache web server. Your site may already be using
the Apache web server. CrayDoc is designed to integrate smoothly with
already-existing installations of the Apache web server. Refer to the mode that is
best suited to your particular needs and environment:
Stand-alone
CrayDoc has a dedicated Apache installation. This scenario allows for optimal
security and performance. See Section 2.1, page 7 for installation instructions
and more information.
Shared
CrayDoc shares an existing Apache installation. This scenario allows CrayDoc
to coexist with other users of the Apache web server, and it requires the
involvement of the administrator of your existing Apache installation. See
Section 2.2, page 8 for installation instructions and more information.
You must also consider security issues when selecting a mode (see Section 2.3,
page 8).
2.1 Stand-alone Mode
The Stand-alone installation scenario allows for the most control over CrayDoc
security and performance. In this scenario, the Apache web server is configured
with CrayDoc as the primary user. Examples of this scenario include:
• An unused Linux-compatible computer (that is, an extra PC) that you want to
devote to being a CrayDoc server
• Root access to a computer that is not currently running an Apache web server
For this documentation, we will assume you have a Red Hat Linux 7.2 system
running on an average, off-the-shelf PC. The average installation time for a
new Red Hat system is about 60–90 minutes, which includes the installation of
Apache 1.3.12 and Perl 5.6.0 with all the necessary modules.
Once you have Apache and Perl successfully installed, the next step is deciding
where you will install CrayDoc. In a Stand-alone scenario, it is up to you
