14.1.3 Checking InnoDB Availability

To determine whether your server supports InnoDB:

• Issue the SHOW ENGINES statement to view the available MySQL storage engines. Look for DEFAULT in the InnoDB line.

  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.)

• Issue a SHOW VARIABLES statement to confirm that InnoDB is available.

  mysql> SHOW VARIABLES LIKE 'have_innodb';

• 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.
