修改目錄的權限

sudo chown -R xinxingegeya:wheel mysql

查看mysql編碼，

mysql> show variables like '%char%' ;

修改mysql編碼 macOS上安裝 MySQL 默認是沒有 my.cnf 配置文件的，MySQL 使用默認配置運行。若是須要對 MySQL 進行定製，複製「/usr/local/mysql/support-files/」目錄下的一個 cnf 文件到「/etc/」目錄下並重命名爲 my.cnf，添加以下配置，

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
character-set-server=utf8

重啓mysql，查看編碼方式，

mysql> show variables like '%char%' ;
