ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

1、现象：

[root@localhost ~]# mysql -u root -p

Enter password:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

2、原因：数据库中存在空用户所致

3、解决方案：

1）停用mysql服务：# service mysqld stop

2）输入命令：# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &

3）登入数据库：# mysql -u root mysql

4）mysql> use mysql;

5）mysql> select user,host,password from user; 结果如下：

+------+-----------------------+----------+

| user | host | password |

+------+-----------------------+----------+

| root | % | mima |

| root | localhost.localdomain | mima |

| root | 127.0.0.1 | mima |

| | localhost | |

| | localhost.localdomain | |

+------+-----------------------+----------+

6）将上面查询出来的空用户删除：mysql> delete from user where user='';

7）退出数据库：mysql> quit

8）启动mysql服务：# service mysqld start

9）重新用命令‘mysql -u root -p’登录，OK！
