最近在linux弄mysql时,遇到了1045错误。

CentOS命令登录MySQL时,报错ERROR 1045(28000):Access deniedfor userroot@localhost

(using password: NO)错误解决方法

1、停用mysql服务:# /etc/rc.d/init.d/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;结果如下:

Database changed

5、mysql> UPDATE user SET Password=PASSWORD(‘newpassword’)whereUSER=’newuser’;

结果如下:

Query OK, 3 rows affected (0.00 sec)

Rows matched: 3  Changed: 3  Warnings: 0

mysql> FLUSH PRIVILEGES;

结果如下:

Query OK, 0 rows affected (0.00 sec)

mysql> quit

/etc/init.d/mysql restart

mysql -u newuser –p

Enter password: newpassword

mysql>
