我有一个 docker-compose 文件和一个 Dockerfile。MySQL 已正确安装。我已经设置了MYSQL_ROOT_PASSWORD。但是当尝试访问 mysql db 时，出现错误 - 访问被拒绝。我已阅读本网站的其他主题，但无法获得太多帮助。:(

这是我的 docker-compose 文件：

version: '3'

volumes:
        db_data: {}

services:
    db:
        build:
            context: .
            dockerfile: ./db/Dockerfile
            args:
                - database=iTel
                - password=123
        image: db_image
        volumes:
            - db_data:/var/lib/mysql
        ports:
            - "3306:3306"

和 Dockerfile：

FROM mysql:5.7.15

ARG database
ARG password

RUN echo ${database}
RUN echo ${password}

MAINTAINER me
ENV MYSQL_DATABASE=${database} \
    MYSQL_ROOT_PASSWORD=${password}
ADD ./db/database100.sql /docker-entrypoint-initdb.d
EXPOSE 3306

以下是构建日志：

docker-compose up -d

我实际上丢失了我的root密码,我需要更改它.我按照以下步骤操作:

• 步骤#1:停止MySQL服务器进程.

  步骤#2:使用--skip-grant-tables选项启动MySQL(mysqld)服务器/守护程序进程,以便它不会提示输入密码.

  步骤#3:以root用户身份连接MySQL服务器.

我们可以在这些网站上找到:https://www.howtoforge.com/setting-changing-resetting-mysql-root-passwords#recover-mysql-root-password

mysql> use mysql;
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD("TOOR");
mysql> flush privileges;
mysql> quit

第一个错误,所以我试过:

mysql> use mysql;
mysql> update user set password=PASSWORD("TOOR") where User='root';
mysql> flush privileges;
mysql> quit

总是同样的错误说:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near '("TOO
R") WHERE User='root'' at line 1

我该如何解决这个问题？

我试图通过JHipster创建一个项目并将其部署到Openshif.一切似乎都很正常,但是当运行mvn spring-boot:run或从IDE运行时,没有与MySQL数据库的连接.

错误是:
