[mapserver-users] Installing MapServer on existing Apache/PHP/MySQL on Linux?

No, no; no need for that. MapServer is a simple CGI program, so if your 
Apache has support for CGI programs you're good to go. And while support 
for CGI can be disabled, it's probably enabled.

I've done it a few hundred times (literally) and am glad to share tips. 
Feel free to email me directly with questions, but change the subject so 
it doesn't get caught by my filters.

Step 1: Have you installed the prerequisites? GDAL/OGR and PROJ4 are not 
strictly required, but if you want to do anything about reprojecting 
data or using something other than shapefiles and TIFFs, they're 
strongly recommended.

Step 2: Download and build the source. Download the tar.gz file from 
mapserver.org, extract it, run ./configure with flags for whatever 
features you want, and then "make" Then copy the files into place.

Step 3: Point a browser at /cgi/bin/mapserv and expect an error message 
from having not supplied enough query params. At that point, you're ready.
