+python-django-imagekit comes from https://salsa.debian.org/python-team/modules/python-django-imagekit
+python-django-tinymce comes from https://salsa.debian.org/python-team/modules/python-django-tinymce
+(both modified for stretch/python2). packages under /home/wookey/packages/
+
+need fonts-freefont-ttf (to have truetype freesans available for troggle via PIL)
+need libapache2-mod-wsgi for apache wsgi support.
+
+To keep bots from overloading server use mpm_event intead of mpm_worker
+sudo a2dismod mpm_prefork
+sudo a2enmod mpm_event
+
+Also adjust the numbers in the config file (~/config/apache/mods-available/mpm_event.conf)
+ for our tiddly server:
+	StartServers             1
+	MinSpareThreads          2
+	MaxSpareThreads          15
+	ThreadLimit              25
+	ThreadsPerChild          5
+	MaxRequestWorkers        25
+	MaxConnectionsPerChild   500
+
+Kanboard:
+debian python3-kanboard is a bit too simple, so use http://kanboard.org/ instead
+unpack release files into /home/expo/kanboard
+add this stanza to ~/config/apache/expo.conf
+Alias /kanboard /home/expo/kanboard
+<Directory /home/expo/kanboard>
+	AllowOverride All
+	Require all granted
+</Directory>
+
+Dependencies are php and php-bcmath
+php with mpm_worker and cgi is simple, but we are not using
+mpm_worker any more so this is not possible anyway.
+
+php with mpm_event needs fpm mechanism and apache proxy_fcgi enabled
+This mechanism is a lot more efficient on the server.
+Good docs here: https://www.digitalocean.com/community/tutorials/how-to-configure-apache-http-with-mpm-event-and-php-fpm-on-ubuntu-18-04
+
+apt install php-fpm libapache2-mod-fcgid
+sudo a2dismod php7.4   (this normal config works via mpm_worker)
+sudo a2enconf php7.4-fpm  (this one works with mpm_event via proxy magic)
+sudo a2enmod proxy
+sudo a2enmod proxy_fcgi
+
+apt install php-bcmath (for kanboard)
