mysql表引擎myisam改为innodb

1、进入数据库

2、SELECT  CONCAT('ALTER TABLE `', table_name, '` ENGINE=InnoDB;') AS sql_statements FROM    information_schema.tables AS tb WHERE   table_schema = '数据库名' AND     `ENGINE` = 'MyISAM' AND     `TABLE_TYPE` = 'BASE TABLE' ORDER BY table_name DESC into outfile '/var/lib/mysql/输出文件名';    #找到引擎为myisam的表

3、mysql 数据库名 < /var/lib/mysql/输出文件名     #更改表引擎
