从innodb引擎转换成myisam引擎，看完本文，你应该懂得如何操作以把myisam引擎转换成innodb引擎了（请确保innodb开启，mysql命令行下show engines命令查看）。
mysql> alter table  boblog_history   engine=innodb;
query ok, 2808 rows affected (0.76 sec)
records: 2808  duplicates: 0  warnings: 0
alter table  boblog_blogs     engine=innodb;
alter table  boblog_calendar  engine=innodb;
alter table  boblog_categoriesengine=innodb;
alter table  boblog_counter   engine=innodb;
alter table  boblog_forbidden engine=innodb;
alter table  boblog_history   engine=innodb;
alter table  boblog_linkgroup engine=innodb;
alter table  boblog_links     engine=innodb;
