mysql密码修改_MySQL

[root@slave1 ~]# mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

使用带密码的root用户登录后，修改密码即可，如下：

mysql> update user set password=password('') where user = 'root';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 2 Changed: 0 Warnings: 0

重启mysql，即可用mysql无密码登录了
