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：

# /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’; 
mysql> FLUSH PRIVILEGES; 
mysql> quit 
# /etc/init.d/mysqld restart 
# mysql -uroot -p 
Enter password: <输入新设的密码newpassword> 
mysql>
