One of the amazing features of Saltcorn is multitenancy.
From a single hosting you can run a few Saltcorn sites.
Assumption: You have installed Saltcorn using instruction Install on Ubuntu
To switch to multitenancy mode you need to logon to your server as a Saltcorn user.
If you was root user before:
su - saltcorn
cd ~./.config cp .saltcorn .saltcorn.original
exit systemctl restart saltcorn
systemctl status saltcorn
Go to your saltcorn url, e.g. http://mydomain.com/tenant/create and follow the instructions.
