在Ubuntu上更改默認的mysql存儲引擎

Question

我已經在Ubuntu上安裝了mysql 5.1.49。我已經添加以下行的/etc/mysql/my.cnf

default-storage-engine=innodb 

我已經重新啓動mysqld過程結束，然後運行

mysql> show engines; 
+------------+---------+----------------------------------------------------------------+--------------+------+------------+ 
| Engine  | Support | Comment              | Transactions | XA | Savepoints | 
+------------+---------+----------------------------------------------------------------+--------------+------+------------+ 
| InnoDB  | YES  | Supports transactions, row-level locking, and foreign keys  | YES   | YES | YES  | 
| MRG_MYISAM | YES  | Collection of identical MyISAM tables       | NO   | NO | NO   | 
| BLACKHOLE | YES  | /dev/null storage engine (anything you write to it disappears) | NO   | NO | NO   | 
| CSV  | YES  | CSV storage engine            | NO   | NO | NO   | 
| MEMORY  | YES  | Hash based, stored in memory, useful for temporary tables  | NO   | NO | NO   | 
| FEDERATED | NO  | Federated MySQL storage engine         | NULL   | NULL | NULL  | 
| ARCHIVE | YES  | Archive storage engine           | NO   | NO | NO   | 
| MyISAM  | DEFAULT | Default engine as of MySQL 3.23 with great performance   | NO   | NO | NO   | 
+------------+---------+----------------------------------------------------------------+--------------+------+------------+ 

正如你所看到的MyISAM還是默認的，我缺少什麼？我也跑

sudo find/-name 'my.cnf' 

，以驗證是否有存在於系統

Answer 1

這可能在my.cnf文件的錯誤的部分上沒有其他my.cnf文件。

您需要在[mysqld]部分設置該變量。如果你把它放在配置文件的末尾，它可能在不同的部分，因爲[mysqld]通常是第一部分，而不是最後一部分。

Answer 2

確認您已將default-storage-engine=innodb放入適當的[group]，通常爲[mysqld]。
