MySQL ERROR 1045(28000):用户“bill”@“localhost”的访问被拒绝(使用密码:YES)

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

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.

我为自己找到的最好的解决办法是。

我的用户是声纳，每当我试图从外部或其他机器连接到我的数据库，我得到错误

ERROR 1045 (28000): Access denied for user 'sonar'@'localhost' (using password: YES)

此外，我正在尝试从另一台机器和通过詹金斯工作我的URL访问是

alm-lt-test.xyz.com

如果你想远程连接，你可以用以下不同的方式指定它:

mysql -u sonar -p -halm-lt-test.xyz.com
mysql -u sonar -p -h101.33.65.94
mysql -u sonar -p -h127.0.0.1 --protocol=TCP
mysql -u sonar -p -h172.27.59.54 --protocol=TCP

要访问这个URL，你只需要执行以下查询。

GRANT ALL ON sonar.* TO 'sonar'@'localhost' IDENTIFIED BY 'sonar';
GRANT ALL ON sonar.* TO 'sonar'@'alm-lt-test.xyz.com' IDENTIFIED BY 'sonar';
GRANT ALL ON sonar.* TO 'sonar'@'127.0.0.1' IDENTIFIED BY 'sonar';
GRANT ALL ON sonar.* TO 'sonar'@'172.27.59.54' IDENTIFIED BY 'sonar';

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。
