Question

我刚刚将MySQL数据库从5.5更新到5.6。我尝试follow best practices，因此我使用mysql_config_editor创建了.mylogin.cnf文件：

mysql_config_editor set --login-path=local --host=localhost --user=example --password

但是，当我尝试mysql --login-path=local时，我收到此错误：

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

但是，我仍然可以使用mysql -u example -p登录，然后在提示符下粘贴密码。我已经三次检查我在mysql_config_editor命令中使用了正确的密码。

我的补助金看起来像这样：

mysql> show grants;
+------------------------------------------------------------------------------+
| Grants for example@localhost                                                 |
+------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'example'@'localhost' IDENTIFIED BY PASSWORD <secret>  |
| GRANT ALL PRIVILEGES ON `example`.* TO 'example'@'localhost'                 |
+------------------------------------------------------------------------------+
2 rows in set (0.00 sec)

当我重启MySQL时，这是/var/log/mysql/error.log的输出：

您是否在日志中看到任何可能表明我无法使用--login-path选项登录的内容？

Answer 1

您应该使用套接字在本地登录。尝试使用mysql_config_editor选项来指定--socket=/path/to/mysqld.sock命令，该命令对您的MySQL实例是正确的。

Answer 2

为您的密码添加双引号。它对我有用。

为什么我不能使用--login-path = local登录mysql？
