14.1.3 Checking InnoDB Availability 

14.1.3 检查InnoDB 可用性:

确定是否你的server 支持InnoDB：

1.执行命令 SHOW ENGINES; 查看所有不同的MySQL 存储引擎

mysql> SHOW ENGINES;

+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+

| Engine             | Support | Comment                                                        | Transactions | XA   | Savepoints |

| MRG_MYISAM         | YES     | Collection of identical MyISAM tables                          | NO           | NO   | NO         |

| BLACKHOLE          | YES     | /dev/null storage engine (anything you write to it disappears) | NO           | NO   | NO         |

| MyISAM             | YES     | MyISAM storage engine                                          | NO           | NO   | NO         |

| MEMORY             | YES     | Hash based, stored in memory, useful for temporary tables      | NO           | NO   | NO         |

| ARCHIVE            | YES     | Archive storage engine                                         | NO           | NO   | NO         |

| InnoDB             | DEFAULT | Supports transactions, row-level locking, and foreign keys     | YES          | YES  | YES        |

| FEDERATED          | NO      | Federated MySQL storage engine                                 | NULL         | NULL | NULL       |

+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+

9 rows in set (0.01 sec)

 查看默认的存储引擎,查询INFORMATION_SCHEMA ENGINES table.

(现在InnoDB 是默认的MySQL存储引擎)

2.如果InnoDB 不在场, 你有一个mysqld binary 编译没有InnoDB支持
