Linux修改MySql默认存储引擎为InnoDB

一、关闭相关应用

二、停止mysql
bin/mysqladmin -u root -p shutdown

三、备份my.cnf
cd /etc
cp my.cnf my.cnf_bak

四、修改my.cnf
[mysqld] 后加入
vi my.cnf
default-storage-engine=InnoDB

 

五、删除/mysql/data目录下的ib_logfile0，ib_logfile1

否则在启动mysql时会遇到下述错误：
[ERROR] Plugin 'InnoDB' init function returned error.
[ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
[ERROR] Unknown/unsupported table type: InnoDB
[ERROR] Aborting

六、启动mysql
cd /home/administrator/mysql
bin/mysqld_safe -user=root &

七、登录mysql检查修改是否成功
mysql -h ip -u root -p

mysql>show engines;
mysql>show variables like'storage_engine';
