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

您可以打开一个终端并键入locate my.cnf

这些东西对我都没用。我正在使用当前的dmg安装mysql社区服务器。ps显示my.cnf中所有最关键的参数通常都是在命令行上传递的，我不知道这是从哪里来的。在对我的盒子进行全文搜索后，我发现它在:

/ Library / LaunchDaemons / com . oracle, mysql oss。mysqld plist。

你可以在这里修改它们，也可以把它们拿出来这样它就会尊重你在my。cnf里的那些，不管你放在哪里。

享受吧!

macOS sierra 10.12.6 MySQL版本:5.7.18_1 我运行locate my。cnf，路径是

/ usr / local / etc / my . cnf

我正在运行MacOS Mojave(10.14.6)，为了让MySQL识别我的配置文件，我必须将它放在/usr/local/ MySQL -5.7.26-macos10.14-x86_64/etc/my.cnf中。我也有一个符号链接指向它从/usr/local/@mysql/etc/my.cnf。

我试图关闭sql_mode=only_full_group_by，在配置文件中设置该选项是在会话之间保持该设置的唯一方法。配置文件的内容如下:

[mysqld]
sql_mode=NO_ENGINE_SUBSTITUTION

我正在使用MySQL的本机安装，而不是Homebrew设置。

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.
