[Qgis-user] QGIS server and fcgi with ubuntu 12.04

[Ziegler Stefan]

Hi 

I have some problems running QGIS server as fcgi with Ubuntu 12.04. "apachectl -t -D DUMP_MODULES" shows that the fcgid module ist loaded. But I only get errors when trying to run it as fcgi:

[Sun Jun 09 21:24:39 2013] [error] [client 37.35.115.249] Premature end of script headers: qgis_mapserv.fcgi, referer: http://www.catais.org/map/grundbuchplan?startExtent=615721,222428,619877,226198&visibleLayers=Baulinie,Amtliche%20Vermessung%20(schwarz-weiss),Strassenkarte&format=image%2fpng%3b%20mode%3d8bit
[Sun Jun 09 21:24:40 2013] [warn] [client 37.35.115.249] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server, referer: http://www.catais.org/map/grundbuchplan?startExtent=615721,222428,619877,226198&visibleLayers=Baulinie,Amtliche%20Vermessung%20(schwarz-weiss),Strassenkarte&format=image%2fpng%3b%20mode%3d8bit

When commenting out "AddHandler fcgid-script .fcgi" line from fcgid.conf file it only runs as normal cgi and then it's terrible slow. I'm using a self compiled master version of QGIS. Had anyone similar problems with ubuntu 12.04? It worked with the same configuration with Ubuntu 10.04.

Excerpts from virtual host config:

ScriptAlias  /cgi-bin/ /home/catais/catais.org/docroot/cgi-bin/
 <Directory "/home/catais/catais.org/docroot/cgi-bin">
    AllowOverride None
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    #SetHandler fcgid-script 
    #AddHandler fcgid-script .fcgi

    Order allow,deny
    Allow from all
    SetEnv LD_LIBRARY_PATH /home/catais/Apps/qgis_master/lib
 </Directory>

Fcgid.conf:

<IfModule mod_fcgid.c>
  AddHandler    fcgid-script .fcgi
  FcgidConnectTimeout 600
  FcgidMaxRequestLen 134217728

  FcgidMaxProcesses 50
  FcgidMinProcessesPerClass 5
  FcgidMaxProcessesPerClass 20

  ProcessLifeTime 7200
  IPCCommTimeout  7200
  IPCConnectTimeout 300

  FcgidProcessLifeTime 7200

  SocketPath /var/lib/apache2/fcgid/sock
  FcgidInitialEnv LD_LIBRARY_PATH /home/catais/Apps/qgis_master/lib
  FcgidInitialEnv DISPLAY ":0"
  FcgidInitialEnv LANG=de_CH.UTF-8
</IfModule>
