MySQL Server Initialization (as of MySQL 5.7): At the initial start up of the server, the following happens, given that the data directory of the server is empty:
* The server is initialized.
* An SSL certificate and key files are generated in the data directory.
* The validate_password plugin is installed and enabled.
* A superuser account 'root'@'localhost' is created. A password for the superuser is set and stored in the error log file. To reveal it, use the following command:
shell> sudo grep 'temporary password' /var/log/mysqld.log
shell> mysql_secure_installation
