mysql docker 中的用戶 'root'@'localhost' 的訪問被拒絕

Question

在以下命令中運行 docker mysql 容器

docker run -it --name mysql  -e MYSQL_ROOT_PASSWORD=123456 mysql

然后 docker 創建一個正在運行的 mysql 容器，日志為

嘗試訪問容器

mysql -h localhost -u root -p

它要求輸入密碼，使用 123456 作為密碼失敗； 使用空密碼也失敗。

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

Answer 1

docker exec -it mysql mysql -uroot -p , then a prompt is out to input the password with 123456 , then It can successfully get access to the mysql command line. 但是為什么我不能使用 tableplus

從上面的評論中可以看出，您可以訪問容器內的mysql服務器，因此tableplus的問題不是容器 root 密碼。

只需發布端口，它應該可以工作，

docker run -it -p 3306:3306 --name mysql  -e MYSQL_ROOT_PASSWORD=123456 mysql

此外，似乎tableplus連接主機MySQL而不是容器一，因為容器沒有在您的情況下發布端口，因此它試圖連接到其他地方。

Answer 2

可能是此 MySQL 安裝使用了操作系統的身份驗證機制。 而不是根密碼。

要測試是否是這種情況，請執行以下命令：

sudo mysql -u root

它會詢問您的操作系統特權密碼，而不是 MySQL 根密碼（可能未設置）。

進入后，您可以像往常一樣添加新用戶，如 MySQL 手冊和教程中所述。

此外，您可能想嘗試此處提到的說明：

https://dev.mysql.com/doc/refman/8.0/en/resetting-permissions.html

請參閱“B.4.3.2.3 重置 Root 密碼：通用說明”部分。

如果無法訪問該網站，請在下面引用它（並稍微清理一下）：

如有必要，停止 MySQL 服務器，然后使用 --skip-grant-tables 選項重新啟動它（請參閱如何使用 --skip-grant-tables 啟動 MySQL？了解一些方法）

使用mysql客戶端連接到MySQL服務器； 不需要密碼，因為服務器是用 --skip-grant-tables 啟動的：

外殼> mysql

在 mysql 客戶端中，告訴服務器重新加載授權表，以便帳戶管理語句起作用：

mysql> 刷新權限；

然后更改'root'@'localhost' 帳戶密碼。 將密碼替換為您要使用的密碼。 要更改具有不同主機名部分的 root 帳戶的密碼，請修改說明以使用該主機名。

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

您現在應該能夠使用新密碼以 root 身份連接到 MySQL 服務器。 停止服務器並正常重新啟動它（沒有 --skip-grant-tables 選項）。

Answer 3

我有同樣的問題，我修復了它用私有 ip 替換本地主機：

mysql -u root -p -h 192.168.10.4
