Dear users, 

I now installed on SUSE SLES 15 QGIS 3.6.1 and with that it worked
immediately.

I use mapserv_qgis,fcgi in /usr/bin.


Apache-configuration looks like:

..

 ErrorLog /home/kai/qgis-server-error.log
  CustomLog /home/kai/qgis-server-access.log combined
  # Longer timeout for WPS... default = 40
  FcgidInitialEnv LC_ALL "en_US.UTF-8"
  FcgidInitialEnv PYTHONIOENCODING UTF-8
  FcgidInitialEnv  LANG "en_US.UTF-8"
  FcgidInitialEnv QGIS_DEBUG 0
   FcgidInitialEnv  QGIS_SERVER_LOG_LEVEL 0
   FcgidInitialEnv QGIS_SERVER_LOG_FILE "/home/kai/qgislog.log"
#   FcgidInitialEnv DISPLAY ":99"
    FcgidInitialEnv QGIS_AUTH_DB_DIR_PATH "/home/kai/default/"
   FcgidInitialEnv QGIS_AUTH_PASSWORD_FILE
"/home/kai/default/qgis-auth.db"


 ScriptAlias /cgi-bin/ "/usr/bin/"

# "/srv/www/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have that configured.
#
 <IfModule mod_fcgid.c>


<Directory "/usr/bin/">

	  Options +ExecCGI -MultiViews +FollowSymLinks
	 AddHandler fcgid-script .fcgi
#	 FcgidInitialEnv QGIS_PROJECT_FILE "/home/kai/testprojekt.qgis"

	    <IfModule mod_access_compat.c>
			    Order allow,deny
			    Allow from all
	    </IfModule>
	  #Allow from all
	 #-MultiViews +FollowSymLinks Order allow,deny

	  Require all granted
   #   SetHandler fcgid-script

</IfModule>

Best regards, Kai

Dear users,

I try to set up a getMap Request to QGIS-Server 3.6.0 on a SUSE LTE
15-system.

The GetCapabilities-Request works well. 

And:


If I eg put a wrong layer in a getMap-request, the qgis server talks to
me:

<ServiceExceptionReport version="1.3.0"><ServiceException
code="LayerNotDefined">
Layer "xyz_4326" does not
exist</ServiceException></ServiceExceptionReport>

...so far so good.

but:


But if I send the (I think) correct request to qgis-server:

http://myserveraddress/cgi-bin/qgis_mapserv.fcgi?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=7.62,52.22,7.82,52.31&
CRS=EPSG:4326&WIDTH=300&HEIGHT=300&LAYERS=adressen_4326&FORMAT=image/png&Map=/home/blabla/adressen.qgs


..the Apache-Server says:

Server-Error
Premature end of script headers: qgis_mapserv.fcgi 


This usually means that QGIS server crashed, hard to tell why.




in the qis-server log it looks not so bad:

Has anybody an idea what is going wrong? Might it be a problem with the
output of an image?


No idea, sorry, you may try to increase logging level btw (see the docs
to know how).

You can also try to ssh into the machine and run qgis_server.fcgi
directly passing QUERY_STRING in the environement.

Hope that helps.





Thank you in advance, Kai
