A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.


You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.


Also, the account for the anonymous user has been removed.


In addition, you can run:


  /usr/bin/mysql_secure_installation


which will also give you the option of removing the test database.
This is strongly recommended for production servers.


See the manual for more instructions.

New default config file was created as /usr/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
