Hi Andrew: In general the only things that need to be in your document root are
graphics, scripts and pure HTML that will be
directly accessible via a users browser. Assets like mapfiles, data, symbols
and templates should be elsewhere. Those files will
need to be accessible (readable) by the user the web server is running under
but should not be owned by that user.
The temp space for the images MapServer creates is also in document root but I
consider that part of the overall setup and
not a project component. That directory needs to be owned and writable by the
user the web server runs as.
I often setup a project like so:
/project
/data
/mapfiles
/templates
/htdocs
/javascript
/images
/html
and then symlink the htdocs directory into document root. Could just copy it
too.
Your document root might look like:
/htdocs/
/tmp (this is the MapServer temporary directory, owned by the user your httpd
is running as)
/project (this is a symlink to the main project's /htdocs directory)
As for your example files.
1) In Hello.html, remove the hidden variable 'map-web-imagepath', it just
confuses things.
2) In Hello.map, you're missing a closing END (which is why you see the error
message you do). I believe if you add it you'll get
the colored image you're expecting. Typically I indent all objects in mapfile
to make it easier to debug:
MAP
... map level attributes ...
WEB
... web level attributes ...
END
LAYER
... layer level attributes ...
END
END
As for the book. It's just a bit dated and can't adequately cover all platforms
(and MacOS isn't one of them). At a minimum you'll
need to use sudo most likely to run administrative commands.
Hope this helps...
Steve

Hi Listers,
I am trying to learn MapServe as a beginner and I am having lots of trouble
with the fundamentals of setting up the program. I am running Mac OSX Snow
Leopard with Apache.
According to my httpd-conf file, my document root is /usr/local/apache2/htdocs/
; however, when I use the tutorial data the files need to be in my root
directory i.e. /ws4w/etc... I thought that all the data had to be in the
document root. Can someone explain this to me please?
Another problem I am having...I bought the book "Beginning Mapserver: Open
Source GIS Development". The first simple example is a "Hello World" example.
The program starts off with a "Click Me" botton and a broken image. When you
click on the button, it is supposed to show the "Hello World" text. When I
click, I get an error like this: "msLoadMap(): Premature End-of-File." Below
are the two files that I used for the program"
Hello.html
<html>
<head><title>MapServer Hello World</title></head>
<body>
<form method=POST action="/cgi-bin/mapserv">
<input type="submit" value="Click Me">
<input type="hidden" name="map"
value="/home1/mapdata/Hello.map">
<input type="hidden" name="map-web-imagepath"
value="/usr/local/apache2/htdocs/">
<form>
<IMG SRC="[img]" width=400 height=300 border=0>
</body>
</html>
Hello.map
# This is our "Hello World" maple
NAME "Hello_World"
SIZE 400 300
IMAGECOLOR 249 245 186
IMAGETYPE png
EXTENT -1.00 -1.00 1.00 1.00
WEB
TEMPLATE "http://192.168.2.12/~andrewlewin/hello.html";
IMAGEPATH "/usr/local/apache2/htdocs/"
IMAGEURL "/tmp/"
END
The book suggests that I should Configure MapServer and Apache like this:
shapes:
mkdir /home/mapdata
chown nobody:nobody /home/mapdata
chmod u+rx /home/mapdata
images:
mkdir /var/www/htdocs/tmp
chown nobody:nobody /var/www/htdocs/tmp
chmod u+rx /var/www/htdocs/tmp
The problem is that when I try to run these commands, I get a "Permission
denied" error. How can I get permission to do this. I remember when I was
installing the various components from binaries that there was a command to ask
me for my password before I did anything to the directory, but I forgot. Can
anyone tell me?
Sorry for posting all this at once. I believe once I figure out these problems
I will be able to move on.
Thanks,
Andrew
