使用〜/ .my.cnf更改默認的mysql存儲引擎

Question

我正在使用MySQL 5.5，並嘗試僅為自己更改默認存儲引擎。 我嘗試按照在這里找到的說明在主目錄中創建.my.cnf文件：

http://dev.mysql.com/doc/refman/5.5/en/storage-engine-setting.html

http://dev.mysql.com/doc/refman/5.5/en/option-files.html

您可以在這里看到我到目前為止所做的更改：

selah@selah-OptiPlex-9020:~$ cat .my.cnf
[mysqld]
default-storage-engine=MyISAM
selah@selah-OptiPlex-9020:~$ sudo /etc/init.d/mysql restart
[sudo] password for selah: 
 * Stopping MySQL database server mysqld                                                                                                  [ OK ] 
 * Starting MySQL database server mysqld                                                                                                  [ OK ] 
 * Checking for tables which need an upgrade, are corrupt or were 
not closed cleanly.

但是MyISAM仍然不是默認值！

我該如何工作？

編輯：記錄下來，我只是可以通過編輯/etc/mysql/my.cnf文件並重新啟動計算機（僅重新啟動該過程失敗）來使此工作正常。 但是，我仍然想了解如何僅為我的用戶更改此設置！

Answer 1

default_storage_engine是服務器設置，而不是連接設置。 mysqld服務器不會讀取您的用戶“〜/ .my.cnf”，而客戶端僅讀取[client]部分，而不是[mysqld]部分。

您可以通過〜/ .my.cnf中[client]部分的init-commend commend更改它：

init-command="SET default_storage_engine=MYISAM;"
