对于MySQL数据库,如果你要使用事务以及行级锁就必须使用INNODB引擎。如果你要使用全文索引,那必须使用myisam。 INNODB的实用性,安全性,稳定性更高但是效率比MYISAM稍差,但是有的功能是MYISAM没有的。修改MySQL的引擎为INNODB,可以使用外键,事务等功能,性能高。本文主要介绍如何修改MySQL数据库引擎为INNODB,接下来我们开始介绍。
首先修改my.ini,在[mysqld]下加上:
default-storage-engine=INNODB
其中的蓝色字体是要指定的数据库引擎名称。
用sql语句修改已经建成表的引擎:
alter table tableName type=InnoDB
下面贴出我的my.ini文件供参考:
[mysqld] basedir=C:\Program Files\VertrigoServ\Mysql\ datadir=C:\Program Files\VertrigoServ\Mysql\data\ port =3306 key_buffer =64M max_allowed_packet =1M table_cache =128 sort_buffer_size =512K net_buffer_length =8K read_buffer_size =256K read_rnd_buffer_size =512K myisam_sort_buffer_size =68M default-storage-engine=INNODB [mysqldump] quick max_allowed_packet =116M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [isamchk] key_buffer =20M sort_buffer_size =20M read_buffer =62M write_buffer =62M [myisamchk] key_buffer =20M sort_buffer_size =20M read_buffer =62M write_buffer =62M [mysqlhotcopy] interactive-timeout
按照以上的代码提示操作,我们就能够成功地修改MySQL数据库引擎为INNODB了。本文就介绍到这里,相信一定会带给您收获的!
