Question

我已经坚持了好几天。我已经安装了mysql。什么对我有效，进入mysql ..

launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

$(brew --prefix mysql)/bin/mysqld_safe --skip-grant-tables --skip-networking

mysql -u root // or just mysql

现在我进入了。根据查询结果，我已经成功更改了'root'@'localhost'的密码。

mysql> select host, user, authentication_string from user;
+-----------+------------------+------------------------------------------------------------------------+
| host      | user             | authentication_string                                                  |
+-----------+------------------+------------------------------------------------------------------------+
| localhost | mysql.infoschema | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | mysql.session    | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | mysql.sys        | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | root             | pissword                                                               |

但是，退出该过程并正常启动服务器后，我仍然无法访问mysql。

mysqladmin -u root shutdown

launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

mysql -u root -ppissword

mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

也许我可以检查日志或其他我不知道的东西。请帮忙。

我认为您更改密码的方式存在问题。正确的语法是

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('mypass');

别忘了在那之后刷新特权：

FLUSH PRIVILEGES;

问题是，在authentication_string列中，您将拥有密码的哈希，而不是原始密码。这就是PASSWORD函数的作用。

验证字符串正确时，拒绝用户“ root” @“ localhost”的访问（使用密码：是）
