Suse发生了错误Access denied for user ''@'localhost' to&

  好久没实用MySQL了,上次由于装了Banq的论坛系统。在用MySQL Administrator进去的时候居然提示mysql error number 1045 access denied for user 'admin'@'localhost' (using password: YES)的错误,看来密码是对了,username错了。最后发现自己居然犯了个第几错误,username应该是root,唉!

  同一时候找了别人的资料。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,出现例如以下错误:Access denied for user ''@'localhost' to database 'mysql'

  还有。输mysql能够,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ROOTpassword时出错

  update user set password = '123456' where user ="root" //这样写是错的,密码事实上不是123456

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

  详细操作步骤:

  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!
