- 这个问题烦恼一天了，现在终于得以解决。分享给大家
- 首先贴出来，亲测不可行的博客连接：

- 也可能是我执行的方法不对，也不是有意诋毁各位博主
- 一、首先要知道怎么查看Mac下诸如/usr、/etc等等的文件夹
正常打开Finder的话显示界面是这样：（是看不到这些个文件夹在哪里的）
那么我们要怎么做呢？
各位可以打开Finder后按快捷键：command + shift + G 后如下图：
在输入框中输入：/usr 或 /etc 就可以查看了
具体的各位请看这里：http://www.cnblogs.com/elfsundae/archive/2010/11/30/1892544.html 感谢这位博主
- 二、现在开始修改
首先打开『终端』 —> 输入 mysql -u root -p ->密码->回车—>连接到数据库
然后输入 show variables like '%char%';
显示下图：
如果您和我的不同，那请您往下看。
用上面打开/usr文件夹的方法，打开：
百度翻译了一下，这个文件在说这是一个例子，解释格式要如何写。
然后我们可以试着编辑它，发现：
点击复制，之后全选这个文档内容，复制以下代码，覆盖文档原有内容：
# Example MySQL config file for small systems. # # This is for a system with little memory (<= 64M) where MySQL is only used # from time to time and it's important that the mysqld daemon # doesn't use much resources. # # MySQL programs look for option files in a set of # locations which depend on the deployment platform. # You can copy this option file to one of those # locations. For information about these locations, see: # http://dev.mysql.com/doc/mysql/en/option-files.html # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] default-character-set=utf8 #password = your_password port = 3306 socket = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] default-storage-engine=INNODB character-set-server=utf8 collation-server=utf8_general_ci port = 3306 socket = /tmp/mysql.sock skip-external-locking key_buffer_size = 16K max_allowed_packet = 1M table_open_cache = 4 sort_buffer_size = 64K read_buffer_size = 256K read_rnd_buffer_size = 256K net_buffer_length = 2K thread_stack = 128K # Don't listen on a TCP/IP port at all.

文件名改为 my.cnf
之后复制这个文件，打开Finder 用之前的方法打开/etc ，将 my.cnf 粘贴至此处
最后 打开『偏好设置』 重启MySQL：
现在 打开你的『终端』：
如果你也是这样，恭喜修改成功。
