[Lizmap] Lizmap/qgis server : cache management (seeding)

Tue May 16 03:08:42 PDT 2023

Good morning,

Thanks for your message, i have currently one only Qgis server
installed/available.
Sorry but what do you mean by "enhance the number of QGIS Server available
?"

Following to my previous message, regarding my initial and main issue, For
information, when i do :

php lizmap/console.php project:load

i get :

*/var/www/lizmap/lizmap-web-client-3.6.3# php lizmap/console.php project:load
Enter the repository lizmaptest
Get the project zios
1 request(s) return success for the project zios
Enter the repository aero
Get the project aero_v2
1 request(s) return success for the project aero_v2
Enter the repository dr0
Get the project forages
1 request(s) return success for the project forages
Get the project forages_2154
1 request(s) return success for the project forages_2154
Get the project dr0
1 request(s) return success for the project dr0
Get the project forages_2154_with_fond
1 request(s) return success for the project forages_2154_with_fond*

*But when i do : *

*php lizmap/console.php wmts:capabilities -v dr0 forages_2154
No layers configured with cache!*

*Do you know where the problem comes from ?*

In parrarel, always with the aim of improving performance, i tried to
edit my vhost apache in adding :

FcgidInitialEnv QGIS_SERVER_PARALLEL_RENDERING "1"

and

FcgidInitialEnv QGIS_SERVER_CACHE_DIRECTORY "/tmp/"

(Is it a good idea or i should rather keep the default value ('cache
in profile directory') ?

i setted this path because into my lizmap cache config i noticed :
cache root directory :  /tmp/)

Still in parralel, I discovered the existence of these 2 qgis server
plugins. Would it be adviced to installing them?
https://github.com/3liz/qgis-server-wmts-cache-plugin

https://github.com/3liz/qgis-server-tiles-plugin

Eventually, I'm taking the liberty to paste below an update of my qgis
server logs :

I'm surprised to not read in the environment summary logs, the new
enviro variables 'FcgidInitialEnv QGIS_SERVER_PARALLEL_RENDERING'
and 'FcgidInitialEnv QGIS_SERVER_CACHE_DIRECTORY'

How to ensure that the cache server is functional and taken into account?
