报错：

创建数据库的时候：

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

解决办法：

都是在终端命令行下面操作的，建议在操作前重新设置一下path。

方法一：
1.关闭mysql
# service mysqld stop
2.屏蔽权限
# mysqld_safe --skip-grant-table
屏幕出现：Starting demo from .....
3.新开起一个终端输入
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
mysql> FLUSH PRIVILEGES;//记得要这句话，否则如果关闭先前的终端，又会出现原来的错误
mysql> \q
