service mysqld start

mysql -u root -p进入mysql
\q退出

 

ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'mysql'

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
