this creates also a default db with default login/passw admin/admin?

If yes, is there a way to modify the default login/passw during this bootstrap setup? And if no, how to create a new db and make it the default one + custom login/passw?

Thank you to point me in the right direction.

@ssstofff I do not know why I answered, but maybe it will help the rest. This magic script does not create any default databases. You should do it yourself. You have two ways or you make a database with demo or you make an empty database and start your activities. In the process of creating databases, you will come up with login and password. Start with this: http://YourServerIP:7073/web/database/manager/

@morikoff The reason we are not creating any database is that the script can be used for setting up the production system as well, and we don't want it to poppulate un-necessary databases just for sake of installation. Could be a good improvement to have "command line parameters" in the script.

line4: requires sudo in all the apt-get commands if not running as '

line6 as well.

was this designed to run as root?

Before performing line 9, it is advisable to install a package gdebi:

sudo apt install gdebi -y

gdebi is already mentioned as package for installation at line 4.

@parthivgls yes, I saw. and it is right. But for some unknown reason, it didn't work for me. Perhaps it is necessary to do the installation of packages, and then the update. And the gdebi package is updated.

sudo apt-get install postgresql postgresql-server-dev-12 build-essential python3-pillow python3-lxml python3-dev python3-pip python3-setuptools npm nodejs git gdebi libldap2-dev libsasl2-dev  libxml2-dev libxslt1-dev libjpeg-dev -y
sudo apt-get update && apt-get upgrade -y
