Issue the SHOW ENGINES statement to view the available MySQL storage engines.

mysql> SHOW ENGINES;

Alternatively, query the INFORMATION_SCHEMA.ENGINES table.

mysql> SELECT * FROM INFORMATION_SCHEMA.ENGINES;

(Now that InnoDB is the default MySQL storage engine, only very specialized environments might not support it.)

If InnoDB is not present, you have a mysqld binary that was compiled without InnoDB support and you need to get a different one.

If InnoDB is present but disabled, go back through your startup options and configuration file and get rid of any --skip-innodb option.
