Suse中出错Access denied for user ''@'localhost' to&

　　好久没有用MySQL了，上次因为装了Banq的论坛系统，在用MySQL Administrator进去的时候竟然提示mysql error number 1045 access denied for user ‘admin‘@‘localhost‘ (using password: YES)的错误，看来密码是对了，用户名错了，最后发现自己竟然犯了个第几错误，用户名应该是root，唉!

　　同时找了别人的资料，一起发上来，供下次使用。

　　Access denied for user ‘‘@‘localhost‘ to database

　　我在Suse Linux 10.2下用自带光盘用Yast2安装Mysql 5.0, 装好后在终端输入mysql, mysql

　　成功启动，退出，再输入 mysqladmin -u root password XXXXX， 出现错误： mysqladmin: connect to server at ‘localhost‘ failed

　　error: ‘Access denied for user ‘root‘@‘localhost‘ (using password: NO)‘

　　如先输入mysql,成功启动后输入use mysql,出现如下错误：Access denied for user ‘‘@‘localhost‘ to database ‘mysql‘

　　还有，输mysql可以，输mysql -u root就出错了：

　　Access denied for user ‘root‘@‘localhost‘ (using password: NO).

　　The reason is:

　　是昨日更新ROOT密码时出错

　　update user set password = ‘123456‘ where user ="root" //这样写是错的，密码其实不是123456

　　应该为update user set password = password (‘123456‘) where user = "root"

　　具体操作步骤：

　　关闭mysql:

　　# service mysqld stop

　　然后:

　　# mysqld_safe --skip-grant-tables

　　启动mysql:

　　# service mysqld start

　　mysql -u root

　　mysql> use mysql

　　mysql> UPDATE user SET Password=PASSWORD(‘xxx‘) WHERE user=‘root‘;

　　mysql> flush privileges;

　　mysql>\q

　　That‘s it. I hope those above could do a little favor for you!
