修改MySQL的数据库引擎为INNODB的方法_MySQL

May 30, 2016 pm 05:11 PM

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 
Copy after login

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 
Copy after login

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 
Copy after login

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!

How does MySQL index cardinality affect query performance? How does MySQL index cardinality affect query performance? Apr 14, 2025 am 12:18 AM

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
