@parmonov98 Note that the password that you pass in the parameter is the password for the new user.

And MySQL credentials for new DB/user creation will be taken from the MySQL config file ~/.my.cnf.
If you don't have one, you can simply create a .my.cnf file in the home directory, with

[client]
host=localhost
user=[your-db-user]
password=[your-db-pass]

If ~/.my.cnf doesn't exist, you will be prompted for the root password. For an automated environment, it's recommended to make use of the MySQL config file.
