Single User Setup

The default instructions place the cgi-bin and html documents beneath the root web server directory. This means that only one set of DA cgi programs may be executing at a time on a given server - generally accesible from the URL, /cgi-bin/DA/.

However, it may be that more than one person wants to have a running copy of the DA software, say for testing changes to the code. In this case each user might like to install the software in his or her own home directory, then install new production versions in the top level directory.

The mechanism for accomplishing this is the use of the public_html and user script feature of httpd, that allows a user to place html documents in a subdirectory of their home directory called public_html, and cgi scripts in a directory called cgi-bin.

The following assumes that the public_html and user cgi-bin mechanisms are turned on at your server. We also assume that you have read the default installation instructions for the DA atlas software.

Assume the user name is jones, whose home directory is /usr/people/jones/, jones has sub-directories public_html and cgi-bin under his home directory, and the above features are turned on in the Web server.
