then just clone the sysvinit script as i have done years ago before 
syetemd on dozens of machines without ever touch mysqld_multi - why is 
that so hard to grasp?

*that* was missing from the very begin but still RTFM
https://dev.mysql.com/doc/refman/5.7/en/mysql-install-db.html

in my google search field is nothing more than "mysql init database"

and guess what - when you have *somewhere* a running instance you can 
just shut it down, rsync the "mysql" folder from the datadir to the new 
instance and just fire it up - that's how i clone and init mysqld 
instances since 15 years, i explained that already

tell me something new - but there is no difference how you connect to a 
databaseserver - just host/port or host/socket - so what
