mac mysql乱码的解决办法：1、找到并打开my.cnf文件；2、添加代码为“character-set-server=utf8 init_connect='SET NAMES utf8...”即可。

本文操作环境：macOS10.15系统、Mysql5.7.26版、macbook pro 2020电脑。

mac下MySQL出现乱码的解决方法

本文说下mac下的处理，其实处理方式是一样的，我电脑的mysql版本是5.7.26-log

网上很多帖子都说去/usr/local/mysql/support-files目录拷贝my-default.cnf到/etc/my.cnf 然后和linux的修改方式就一样了，这里说明下：Mac版MySQL在5.7.18之后在my-default.cnf就取消了，于是找不到my-default.cnf也找不到my.cnf，my-default.cnf是之前的版本中才有的文件。

假如不幸你的mysql版本恰好是5.7.18之后的，那么直接新建即可

cd/etcsudovimmy.cnf

拷贝以下代码到my.cnf中
