Docker mysql ERROR 1396（HY000）：'root'@'％'的操作CREATE USER失败

I am trying to set up two containers one running Python, and the other mysql. This is my docker-compose.yml file:

我正在尝试设置两个运行Python的容器，另一个运行mysql。这是我的docker-compose.yml文件：

version: '3'
services:
    python:
        restart: always
        build: ./budget/dockerfiles/python/
        ports:
            - "5000:5000"
        links:
            - db
        depends_on:
            - db
        volumes:
            - ./budget/:/app:z
        entrypoint:
            - python
            - -u
            - /app/run.py

    db:
        build: ./budget/dockerfiles/mysql/
        environment:
            MYSQL_ROOT_PASSWORD: password
            MYSQL_DATABASE: database-name
            MYSQL_USER: root
            MYSQL_PASSWORD: password
        volumes:
            - ./Dump.sql:/db/Dump.sql:z
            - ./Dump_Test.sql:/db/Dump_Test.sql:z
            - ./big_fc.sql:/db/big_fc.sql:z
        ports:
            - "3306:3306"

However, when I run docker-compose up -d --build, the containers are built, but the mysql container crashes. In the log, it says:

但是，当我运行docker-compose up -d --build时，会构建容器，但是mysql容器崩溃了。在日志中，它说：

ERROR 1396 (HY000): Operation CREATE USER failed for 'root'@'%'

I wanted to try what this post suggests, but I cannot even enter the container since it is crashed. Can somebody tell me what I can do?

我想尝试一下这篇文章的建议，但我甚至无法进入容器，因为它已经崩溃了。有人能告诉我我能做什么吗？

According to this github issue, the problem is setting MYSQL_USER to root. It will fail to create the second user 'root'@'%' since it will already exist in the users table.

根据这个github问题，问题是将MYSQL_USER设置为root。它将无法创建第二个用户'root'@'％'，因为它已存在于users表中。

Therefore, this can be solved by only setting MYSQL_ROOT_PASSWORD, MYSQL_DATABASE, and MYSQL_PASSWORD in the docker-compose.yml file.

因此，只需在docker-compose.yml文件中设置MYSQL_ROOT_PASSWORD，MYSQL_DATABASE和MYSQL_PASSWORD即可解决此问题。
