mac os mysql 配置：报错

配置mysql

appledeMacBook-Pro-2:~ apple$ /usr/local/mysql-5.7.15-osx10.11-x86_64/bin/mysqladmin -u root password 12345

报错：error: 'Access denied for user 'root'@'localhost' (using password: NO)'

command not found

ln -s /usr/local/mysql/bin/mysql /usr/bin

然后查阅资料发现 sudo ln -s /usr/local/mysql/bin/mysql /usr/bin

这条语句也不可以

alias mysql=/usr/local/mysql/bin/mysql

报错：

ERROR 1045 (28000): Access denied for user 'apple'@'localhost' (using password: NO)

出现1045错误

感觉死循环了 求高手解答一下 谢谢！
