本文分析了mysql登录报错提示:ERROR 1045 (28000)的解决方法。分享给大家供大家参考,具体如下:

一、问题:

公司linux系统的mysql数据库root用户设置过密码,但常常用命令'mysql -u root -p'登录报错,有时又能登录。登录报错信息为:

[root@localhost ~]# mysql -u root -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Copy after login

二、原因:数据库中存在空用户所致

三、解决方法:

1、停用mysql服务:

# service mysql stop

Copy after login

2、输入命令:

# mysqld_safe --user=mysql --skip-grant-tables --skip-networking & 

Copy after login

3、登入数据库:

# mysql -u root mysql

Copy after login

4、

mysql> use mysql;

Copy after login

5、

mysql> select user,host,password from user;

Copy after login

+------+-----------------------+----------+
| 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='';

Copy after login

7、退出数据库:

mysql> quit

Copy after login

8、启动mysql服务:

# service mysql start
