我得到一臺運行MySQL的服務器，但「本地主機」的「root」用戶被誤刪了。 我重新安裝了MySQL服務器。Ubuntu MySQL服務器 - 權限和用戶問題
我以用戶debian-sys-maint的身份登錄並重新創建用戶「root」。 現在，我有以下用戶：
+-----------+------------------+
| host | user |
+-----------+------------------+
| % | root |
| 127.0.0.1 | root |
| srvname | root |
| localhost | debian-sys-maint |
| localhost | root |
+-----------+------------------+
但是，如果我運行：
> grant all privileges on *.* to "root"@"localhost" identified by "password";
了：
ERROR 1045 (28000): Access denied for user 'debian-sys-maint'@'localhost' (using password: YES)
更新＃1：
登錄爲用戶「根」。

在應用該線程中描述的步驟之後，我仍然不能再向用戶「root」授予權限。參見更新＃1。 – Wolfchamane
