After some series of struggle with the conventions and package versions, I was finally able to complete the setup.
Meanwhile, I felt putting forward some immediate concerns as discussion with everyone.
Password Validation control
case : our mysql installation wasn’t allowing MEDIUM strength validation. I had to alter the whole server configuration to pass through the installation.
suggestion: a variable to allow password generator to generate random passwords with the required strength value
case : our server had a different connection collation / charset
suggestion: allowing to pass the connection collation during the setup
Mysql Installation Error !! #1171 - All parts of a PRIMARY KEY must be NOT NULL; if you need NULL in a key, use UNIQUE instead
case : mysql version 5.7+ doesn’t allow NULL values for primary keys
I had to update the SQL line 174 to pass through.
