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

今天在rhel5.5 下安装了一个mysql数据库使用的是yum 的安装方式

安装过程 参照 http://blog.csdn.net/xiamizy/article/details/2072525

安装完成后用root用户进行登录

mysql -uroot -p123456 

总是报 Access denied for user ’root’@’localhost’ (using password: YES)的错误

找了好长时间终于发现了错误 

在给root用户更改密码的时候应该是这样写

UPDATE mysql.user SET Password=PASSWORD('123456') where USER='root';

我错误的写成了 UPDATE mysql.user SET Password='123456' where USER='root';

弄的我很是郁闷

之后又不能登录数据库, 怎么办呢?

用mysqld_safe 模式启动数据库

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

使用正确的语句 

UPDATE mysql.user SET Password=PASSWORD('123456') where USER='root';

# quit 


重新登录 mysql -uroot -p123456


OK 登录成功
注意如果在密码中使用特殊字符,可能不会成功。我在密码使用$的时候发现不能登录。具体怎么解决没有去研究,如果有谁知道,希望给补充一下。


记下这个错误希望能帮助遇到同样问题的人
