[Chameleon] 1.99 Installation

[Paul Spencer]

Ken,

sorry, the documentation is sorely out of date and is being actively 
worked on (well, maybe not this minute, but Real Soon Now ;))

answers inline ...

Cheers,

Paul

this is probably out of date.  I'll try to take a look at it today and 
post an updated version on the list ...

a lot of the configuration parameters actually have no meaning to the 
chameleon 1.99 package as it exists in the first beta.  Things like 
default_template are specific to the operation of the Service Instance 
which is not in 1.99.

In the cvs version (hopefully a 1.99 beta 2 will be released shortly), 
the configuration file has been split into two separate files, one for 
configuring chameleon and one for configuring the service instance 
(which will be in beta 2).

The settings that are important to you are:

web_server_path - the URL to chameleon, this can be 
http://<server>/chameleon or just /chameleon/

mapscript_module - the mapscript module you are using, typically 
something like php_mapscript_42.dll or .so

tmp_img_path  - directory to store temp files in, like /tmp/ms_tmp/
tmp_web_path  -URL to the above, typically /ms_tmp/
button_cache_path  - a directory to store cached buttons, its temporary 
but should not be cleaned out regularly on a production server, 
typically /tmp/ms_tmp/buttons/
button_cache_web_path - URL to the above, typically /ms_tmp/buttons/

not required right now

no longer used, ignore

both explained above

these are specific to the service instance mode and can be ignored in 
your installation

Anything that is in chameleon is for chameleon's use, not yours :)  You 
can put your GIS data anywhere you like, you configure that on a 
per-application basis in the MAP file used for that application 
(shapepath).
