更改Ubuntu上的默認mysql存儲引擎

Question

我已經在Ubuntu上安裝了MySQL 5.1.49。 我在/etc/mysql/my.cnf的末尾添加了以下行

default-storage-engine=innodb

我已經重新啟動mysqld進程，然后運行

mysql> show engines;
+------------+---------+----------------------------------------------------------------+--------------+------+------------+

如您所見，MyISAM仍然是默認值，我缺少什么？ 我也跑了

sudo find / -name 'my.cnf'

驗證系統上沒有其他my.cnf文件

Answer 1

它可能在my.cnf文件的錯誤部分中。

您需要在[mysqld]部分中設置該變量。 如果將其放在配置文件的末尾，則可能位於不同的部分，因為[mysqld]通常是第一部分，而不是最后一部分。

Answer 2

驗證是否已將default-storage-engine=innodb放入適當的[group] （通常為[mysqld] 。
