默认选项按给定顺序从以下文件中读取:

/etc/my.cnf 
/etc/mysql/my.cnf 
/usr/local/etc/my.cnf 
~/.my.cnf

在Mac OS X Maverick的情况下，当MySQL通过Homebrew安装时，它位于/usr/local/opt/mysql/my.cnf

rDefault选项按照给定的顺序从以下文件中读取: /etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf

Mac OS X Mavericks的当前MySQL包(在撰写本文时为MySQL -5.6.17-osx10.7-x86_64)在安装期间自动创建my.cnf。

它位于/usr/local/mysql-5.6.17-osx10.7-x86_64/my.cnf 根据您的版本调整路径。

打开终端，使用以下命令:

sudo find / -name my.cnf

In my case, the file did not exist. In MySQL Workbench I went to OPTIONS FILE and found some default values. I clicked apply. It asked for permission. It then created the my.cnf file under /etc. However, it is very important to keep in mind that the first time you click "apply", you do not make any changes to the default configuration. Once the file has been created, you can make changes which will be applied when you click "apply". Otherwise you will not be shown the apply button when you make changes.
