2. mac mysql error

cd ~
vim .bash_profile
加入 export PATH=${PATH}:/usr/local/mysql/bin

sudo /usr/local/mysql/support-files/mysql.server stop
如果遇到pid找不到可在系统偏好设置里手动关闭mysql

输入mysql ;
mysql> select User from mysql.user；

$mysql> UPDATE user SET Password=PASSWORD('my_password') where USER='root';

If you face the unknown field Password error above use:
update user set authentication_string=password('my_password') where user='root';

You must SET PASSWORD before executing this statement的解决方法
