mysql - 使用 ~/.my.cnf 更改默认 mysql 存储引擎

Question

我正在使用 MySQL 5.5，并尝试仅为我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一个 .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

您可以在此处查看我迄今为止所做的更改:

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.

但是 MyISAM 仍然不是默认值!

如何让它发挥作用？

编辑:根据记录，我只能通过编辑/etc/mysql/my.cnf 文件并重新启动计算机(只是重新启动进程失败)来使其工作。但是我仍然想了解如何仅为我的用户更改此设置!

Answer 1

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”，客户端仅读取 [client] 部分，而不是 [mysqld] 部分。

您可以通过“~/.my.cnf”中 [client] 部分中的 init-commend 更改它:

init-command="SET default_storage_engine=MYISAM;"
