How to find out and change the storage engine of tables in MySQL databases?

Find out the storage engine of a table in a database:

SELECT ENGINE
FROM information_schema.TABLES
WHERE TABLE_SCHEMA = 'database'
AND TABLE_NAME = 'table'

Change the storage engine of a table:

ALTER TABLE table ENGINE = type

type can be innodb or myisam or others supported.

Set the default storage engine for the MySQL server:

set

default-storage-engine=type

in /etc/my.cnf.
