MySQL ROOT密码更改

MySQLROOT密码

# mysql -u root -p

Enter password:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

 

# mysql -u root -p password 'newpassword'

Enter password:

mysqladmin: connect to server at 'localhost' failed

error: 'Access denied for user 'root'@'localhost' (using password: YES)' 

网上找到的方法操作很简单，如下：

 

# /etc/init.d/mysqld stop

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

# mysql -u root mysql

mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root' and host='root' or host='localhost';

//把空的用户密码都修改成非空的密码就行了。

mysql> FLUSH PRIVILEGES;

mysql> quit

# /etc/init.d/mysqld restart

# mysql -uroot -p

Enter password: <输入新设的密码newpassword>
