檢查

SHOW VARIABLES LIKE 'innodb_file_per_table';
SHOW VARIABLES LIKE 'innodb_large_prefix'; ?
SHOW VARIABLES LIKE 'innodb_file_format';

-- 修改最大索引長度限制

SET GLOBAL innodb_large_prefix=ON;
SET GLOBAL innodb_file_format=Barracuda;
SET GLOBAL innodb_file_per_table=ON;

2：設置

語句也需要修改

ROW_FORMAT=DYNAMIC;
