報錯：

建立資料庫的時候：

create user newUser;

: ERROR 1227 (42000): Access denied; you need (at least one of) the CREATE USER privilege(s) for this operation

ERROR 1227 (42000): Access denied; you need (at least one of) the RELOAD privilege(s) for this operation

解決辦法：

都是在終端命令列下面操作的，建議在操作前重新設定一下path。

方法一：
1.關閉mysql
# service mysqld stop
2.遮蔽許可權
# mysqld_safe --skip-grant-table
螢幕出現： Starting demo from .....
3.新開起一個終端輸入
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
mysql> FLUSH PRIVILEGES;//記得要這句話，否則如果關閉先前的終端，又會出現原來的錯誤
mysql> \q
