mysql - 怎么修？ : mysql> show variables like 'plugin_dir' ; Does not show plugin_dir location

Question

在此之后post我继续尝试按照这些说明设置 MySQL memcached 用户定义函数: http://stanley-huang.blogspot.com/2010/04/level-3-install-memcached-user-defined.html

但现在当我试图找到 plugin_dir 位置时，我得到:

mysql> show variables like 'plugin_dir';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| plugin_dir    |       | 
+---------------+-------+
1 row in set (0.00 sec)

它是空白的。我错过了什么？

谢谢

检查你的my.cnf

[mysqld]
plugin_dir=/path/to/plugin/directory
