I report my progress here I managed to get a PDF via the GetPrint request by following these steps
1/ Create a fake X server Xvfb :99 -ac -noreset & 2/ Add the option in the fastcgi , for example FastCgiConfig -idle-timeout 70 -maxClassProcesses 50 -minProcesses 3 -init-start-delay 3 -restart-delay 20 -startDelay 15 -initial-env DISPLAY=:99 LD_LIBRARY_PATH=/home/kimaidou/src/qgis/build/lib/ 3/ Restart Apache service apache2 restart After this, I tried the GetPrint request from my QGIS project with a composer containing a HTML item. The request get a PDF as an answer, but the HTML item is empty. I will try with another composer, etc., and report here. By the way, is there a way to pass an HTML string via a parameter to the getPrint request for HTML items, as it is possible for text item ? This would rock !
