[英]Getting “Access Denied” error in MySQL when running it in docker
我目前正在嘗試學習docker,並試圖從運行docker引擎的主機連接到容器中的MySQL實例。 部署容器后,我目前遇到以下錯誤:
ahopkins@Ubuntu:~$ mysql -uadmin -ppassword --protocol=tcp
mysql: [Warning] Using a password on the command line interface can be
insecure.
ERROR 1045 (28000): Access denied for user 'admin'@'172.17.0.1' (using
password: YES)
這是我的設置:
ahopkins@Ubuntu:~$ docker version
Client:
Version: 18.05.0-ce
API version: 1.37
Go version: go1.9.5

Docker Hub當前最新的標簽是8.0.11:

我正在使用以下Linux版本和內核版本:
ahopkins@Ubuntu:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04 LTS
Release: 18.04

ahopkins@Ubuntu:~$ uname -a
Linux Ubuntu 4.15.0-23-generic #25-Ubuntu SMP Wed May 23 18:02:16 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
我知道我的密碼正確。 我已經驗證,因為我可以從運行MySQL的容器登錄數據庫而沒有問題。
這正是我要達到的目的:
ahopkins@Ubuntu:~$ docker pull mysql

到目前為止,事情看起來完全符合我的預期。 一切看起來不錯。 現在,我繼續進行一些數據庫工作:

mysql> ALTER USER 'admin'@'172.17.0.1' IDENTIFIED WITH mysql_native_password;

現在,當我嘗試從主機連接到MySQL服務器時,得到以下信息:
ahopkins@Ubuntu:~$ mysql -uadmin -ppassword --protocol=tcp
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user 'admin'@'172.17.0.1' (using password: YES)
我可以使用netstat看到端口打開:
hopkins@Ubuntu:~$ netstat -anlp | grep 3306
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp6 0 0 :::3306 :::* LISTEN -
非常感謝您的幫助,因為我不知道接下來要看什么並且整日都在戰斗。
顯然MySQL端口(3306)存在問題,因為我很確定沒有其他用途,但是當我更改為端口3308時,它起作用了:
ahopkins@Ubuntu:~$ mysql -P 3308 -uroot -p --protocol=tcp
Enter password:

希望這可以在將來對其他人有所幫助。
