This post follows on from my previous three (most recent first in list) linked below. There is no doubt that in just a short time from now we will probably see a 'one-click' installer to by-pass the next steps but a least this method allows you to change 'in/out' the individual libraries if there is are updates using the usual ' sudo apt update && sudo apt upgrade '. http://www.paulshapley.com/2016/08/qgis-server-bringing-map-into-browser.html http://www.paulshapley.com/2016/07/how-to-install-qgis-server-on-ubuntu.html http://www.paulshapley.com/2016/04/how-to-install-postgresql-95-and.html 1.  Firstly...Create a new QGIS project, add your layers from PostGIS, Shapefiles or raster (geotiff), style and symbolise those layers, set the projection and ensure you've set up your 'OWS Server' in 'Project Properties'. 2.  Let's install the 'Lizmap' Plugin first by going into the 'Plugins' menu then 'Manage

Before we start it is always a good idea to remove and re-install apache2 web server so that we start from the same set up:- To remove Apache2:- $ sudo apt --purge remove apache2 $ sudo apt autoremove To re-install Apache2:- $ sudo apt install apache2 $ sudo /etc/init.d/apache2 restart # or $ sudo service apache2 restart 1. $ sudo apt install apache2 (if not installed already done so as above) 2. $ sudo apt install qgis-server libapache2-mod-fcgid 3. $ sudo a2enmod fcgid 4. $ sudo a2enconf serve-cgi-bin 5. $ sudo service apache2 restart 6. add the following code and don't forget to save the changes:- ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin/"> Options ExecCGI FollowSymLinks Require all granted AddHandler fcgid-script .fcgi </Directory> into /etc/apache2/sites-available/ 000-default.conf $ sudo gedit /etc/apache2/sites-available/000-default.conf # so that it looks like this:- <VirtualHost *:80>

QGIS Web Client 2 (stand-alone) version - Development Installation - Part 1 of 2

-
Before you begin installation (using 'yarn') also at  https://github.com/qgis/qwc2-demo-app/blob/master/doc/QWC2_Documentation.md#quick-start  which was done in Ubuntu 22.04 LTS.  This is my own version documentation (as usual to archive my notes and caveats). This will not install all of the 'qwc-services' or 'micro-services' that the additional modules provide. It is the 'stand-alone' version with the web map client.  If you require additional 'micro-services' you may be better off installing 'Docker' containers here  https://qwc-services.github.io/setup/quick-start/ Here is an overview of the project as at FOSS 2019.  https://blog.sourcepole.ch/assets/2019/qwc2-foss4g19.pdf **There will be differences in the package management systems on other linux distros (excluding Windows)** Lets get started! Open a 'Terminal' :~$ sudo apt install npm :~$ sudo npm install -g yarn :~$ git clone --recursive https://github.com/qgis/qwc2-demo-
