mysql_install_db.sh wrong instructions on how to set root password leading to passwordless root account.

"PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !

To do so, start the server, then issue the following commands:

'/usr/bin/mysqladmin' -u root password 'new-password'

'/usr/bin/mysqladmin' -u root -h hostname password 'new-password'

Alternatively you can run:

'/usr/bin/mysql_secure_installation'

which will also give you the option of removing the test

databases and anonymous user created by default.  This is

strongly recommended for production servers."

While mysql_secure_installation works as expected and changes ALL passwords, commands:

'/usr/bin/mysqladmin' -u root password 'new-password'

'/usr/bin/mysqladmin' -u root -h hostname password 'new-password'

DO NOT change ALL root passwords. Mysql user table after running commands:

MariaDB [(none)]> select Host,User,Password from mysql.user;
