您可以检查文件

/usr/local/bin/mysql.服务器，看看my.conf是从哪里读取的。

通常是从/etc/my.cnf或~/my.cnf或~/.my.cnf

我不知道你使用的是哪个版本的MySQL，但以下是Mac OS X 5.5版本my.cnf文件的可能位置(从这里取):

/etc/my.cnf /etc/mysql/my.cnf SYSCONFDIR / my.cnf $ MYSQL_HOME / my.cnf Defaults-extra-file(使用——Defaults-extra-file =path指定的文件，如果有的话) ~ / .my.cnf

如果在Mac M1和MacOS Monterey 12.0.1中使用Homebrew安装MySQL，则位置为/opt/ Homebrew /etc/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.

你可以在任何你想要的目录下创建你的文件。创建完成后，你可以“告诉”mysql配置的路径:

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
