Lizmap Installation with URL prefix

[lukasspettel]

Description

I am trying to install Lizmap on a server that runs on a portal:

portal.domain.com

The server itself runs on the portal with a prefix(?) added to the url that the server is unaware of to my understanding.

portal.domain.com/prefix

So when I install Lizmap on the server I can access the landing page (no css) but any generated links will point to portal.domain.com/lizmap.

I did not find any solution to this problem.

How can I include this prefix in the installation of lizmap?

Environment

• Lizmap version: 3.3.5
• QGIS Server FULL version: 3.10.4
• QGIS Desktop FULL version: 3.10
• OS (Windows, Linux, MacOS, Android…): Ubuntu 20.04 LTS
• Browser (Firefox, Chrome…): Chrome
• PostgreSQL 12.x + PostGIS 3.0 database

Did you try to rename the lizmap directory to prefix? Do not forget to remove all files from temp/lizmap/ after this change.

I did try to do that. But then the URL for lizmap would be:

portal.domain.com/prefix/prefix

The prefix alone is a landing page for various projects of the portal.

I am currently trying to solve this problem with the urlengine documented in the advanced installation documentation.

Would I be able to solve it with the following settings in the localconfig.ini.php file?

[urlengine]
basePath= /prefix
backendBasePath = /

I changed the localconfig.ini.php to the above mentioned settings and reinstalled Lizmap. Now there is an error when I try to open lizmap:

Error 500. A technical error has occured. Sorry for this trouble.
Error in the main configuration. A plugin doesn't exist

This seems to be due to the changes in localconfig.ini.php.

Problem was solved in Apache configuration on backend server with reverse proxy:

ProxyPass /lizmap/ http://localhost/prefix/lizmap/
ProxyPassReverse /lizmap/ http://localhost/prefix/lizmap/
