[Qgis-user] QGIS Server on CentOS 6

[Bo Gusman]

Hi Andreas.

I have just met with some success for the first time and document here 
what I found, for any others who may encounter the same.

As I described previously, I used the URL from the QGIS Server tutorial 
page which is

http://localhost/cgi-bin/qgis_mapserv.fcgi?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities 


This returns an error, Premature end of script headers.

You corrected me with the following:

http://localhost/cgi-bin/qgis_mapserv.fcgi?map=/path/to/your/qgis-projects/project.qgs&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities 


This now returns me an XML document that appears to describe my test 
map. Huzzah!

I'm now ready to start learning something more about GIS! Thank you for 
your help!

     Bo
