Answer 2

As of MySQL 5.6.8, on Unix platforms, mysql_install_db creates a default option file named my.cnf in the base installation directory.

Read here in the official documentation where the configuration files can be located and in what order they are used.
Short answer:
/etc/my.cnf
/etc/mysql/my.cnf
SYSCONFDIR/my.cnf
$MYSQL_HOME/my.cnf

Answer 3

mysql -I | grep my.cnf
