Question

我正在使用MySQL 5.5并尝试仅为自己更改默认存储引擎。我尝试按照我在此处找到的说明在我的主目录中创建.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

你可以看到我到目前为止所做的更改：

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.

然而，MyISAM仍然不是默认值！

如何让它发挥作用？

编辑：为了记录，我只能通过编辑我的/etc/mysql/my.cnf文件并重新启动我的计算机来完成这项工作（只需重新启动该过程失败）。但是，我仍然想了解如何仅为我的用户更改此内容！

default_storage_engine是服务器设置，而不是连接设置。 mysqld服务器不会读取您的用户'〜/ .my.cnf'，而客户只能阅读[client]部分，而不是[mysqld]部分。

您可以通过'〜/ .my.cnf'中init-commend部分的[client]进行更改：

init-command="SET default_storage_engine=MYISAM;"

使用〜/ .my.cnf更改默认的mysql存储引擎
