MySQL出现Accessdeniedforuser'root&amp_MySQL

登录某台服务器的mysql时候总报错：

mysql2/client.rb:58:in `connect': Access denied for user 'root'@'localhost' (using password: YES) (Mysql2::Error)

解决方法：

在windows 下的解决方法也一样的

[sql] view plain copy

1. # /etc/init.d/mysqld stop
2. # mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
3. # mysql -u root mysql
4. mysql> UPDATE user SET Password= PASSWORD(’newpassword’) where USER=’root’;
5. mysql> FLUSH PRIVILEGES;
6. mysql> quit
7. # /etc/init.d/mysqld restart
8. # mysql -uroot -p
9. Enter password: <输入新设的密码newpassword>
