首先让我提一下,我已经看了很多建议的问题,但没有找到相关的答案。这就是我正在做的。

我连接到Amazon EC2实例。我可以用这个命令登录MySQL根目录:

mysql -u root -p

然后我用host %创建了一个新的用户帐单

CREATE USER 'bill'@'%' IDENTIFIED BY 'passpass';

授予用户bill的所有权限:

grant all privileges on *.* to 'bill'@'%' with grant option;

然后我退出root用户,尝试用bill登录:

mysql -u bill -p

输入正确的密码并得到以下错误:

错误1045(28000):用户“账单”@“localhost”(使用密码:YES)的访问被拒绝


当前回答

如果您使用旧版本的MySQL UI(如SQLYoug),生成的密码带有错误的散列,也会出现这个问题。

用SQL脚本创建用户可以解决这个问题。

其他回答

我也遇到了类似的问题——当我第一次尝试以root用户登录MySQL时,它告诉我访问被拒绝。原来我忘了用sudo…

所以,如果你第一次尝试root失败了,试试:

sudo mysql -u root -p

然后输入密码,就可以了。

我通过删除旧的错误用户“账单”条目来解决这个问题(这是重要的部分:都来自mysql。用户和mysql.db),然后创建和前面一样的用户:

FLUSH PRIVILEGES;
CREATE USER bill@localhost IDENTIFIED BY 'passpass';
grant all privileges on *.* to bill@localhost with grant option;
FLUSH PRIVILEGES;

工作完毕,用户正在连接。现在我将删除一些特权从它:)

对我来说,root有一个默认密码

我用ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password '修改密码;这个方法奏效了

好吧,我不确定,但可能是mysql安装目录中的my.cnf文件是罪魁祸首。 注释掉这一行,问题就可以解决了。

I discovered yet another case that appears on the surface to be an edge case; I can export to the file system, via SELECT INTO .. OUTFILE as root, but not as regular user. While this may be a matter of permissions, I've looked at that, and see nothing especially obvious. All I can say is that executing the query as a regular user who has all permissions on the data base in question returns the access denied error that led me to this topic. When I found the transcript of a successful use of SELECT INTO … OUTFILE in an old project, I noticed that I was logged in as root. Sure enough, when I logged in as root, the query ran as expected.
