第一步、先把数据库服务关闭
第二步、找到my.cnf文件
路径：Macintosh HD/private/etc
备注：如果根目录下找不到private文件夹 使用快捷键 command+shift+. 打开隐形文件
第三步、修改my.cnf文件
修改内容如下：
#更改数据库编码需要更改的
[mysqld]
character-set-server=utf8
[client]
default-character-set=utf8
#备份数据库需要更改的
[mysqldump]
user=root
password=123
如果你没有这个文件自己建一个 我把内容放下边
# For advice on how to change settings please see
