Hi Guillame,
Well, that almost worked, mysql_install_db ran and completed. Now it
won't let me login as root. If I try 'mysql -u root -p'and hit enter
when prompted for a password I get this
Enter password:
ERROR 2013 (HY000): Lost connection to server at 'handshake: reading
initial communication packet', system error: 104
and I have to use 'sudo systemctl start mariadb.socket' instead of
'sudo systemctl start mariadb.service' but it has to be restarted if
authentication fails. 
so the rest of the KB you sent does no good since I still can't access
the DB, or even view what was created by the installer command.
