後查出是mac的問題，MySQL5.7之後針對mac端，並且沒有my-default.cnf的用戶，需要調整配置信息 。
修改期間必須關閉mysql
我們要在/etc下新建my.cnf
$ cd /etc
$ sudo vim my.cnf
my.cnf文件如下
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
