我没有使用映射卷来实现数据持久性，而是使用了托管卷，它不再崩溃

以前的

db:
        image: mysql:8.0.22
        container_name: mysql
        restart: always
        volumes:
            - ./mysql:/var/lib/mysql
        environment:
            MYSQL_DATABASE: mydb
            MYSQL_USER: root
            MYSQL_PASSWORD: root
            MYSQL_ROOT_PASSWORD: root
        networks:
            - laravel

现在

db:
        image: mysql:8.0.22
        container_name: mysql
        restart: always
        volumes:
            - db_data:/var/lib/mysql
        environment:
            MYSQL_DATABASE: mydb
            MYSQL_USER: root
            MYSQL_PASSWORD: root
            MYSQL_ROOT_PASSWORD: root
        networks:
            - laravel

volumes:
    db_data: {}

当我开始与docker合作时，我发布了这个问题。。。经过一些研究，我发现罪魁祸首是不同的Linux发行版对同一用户名使用了不同的用户id。所以基本上是权限问题

请阅读这篇文章，如果这对你有意义

我必须从ubuntu中删除当前用户，并添加与alpine用户匹配的用户。那是我当时使用的发行版

也许这就是我想的答案。。。如果你正在使用ubuntu和alpine Linux的docker镜像。。。那么用户名和用户id可能会有所不同

我引用的这篇文章展示了如何从当前Linux发行版中删除用户，并添加具有不同用户id的同一用户。

有趣！我尝试使用托管卷，mysql没有崩溃。现在

db

服务有以下

命令：--default authentication plugin=mysql\u native\u password

和

卷：

有

-db\u data:/var/lib/mysql

，卷定义在底部。但是，现在连接被拒绝

docker compose exec db mysql-u root-p

告诉我

错误2002（HY000）：无法通过socket'/var/run/mysqld/mysqld.sock'（2）连接到本地mysql服务器

。有人知道吗？我猜我之前的映射与docker有一些windows/linux文件系统兼容性问题。我试图在我的项目文件夹（docker从WSL2映射的windows文件系统）上持久化mysql数据库。使用托管卷解决了这个问题，我想我尝试了这个解决方案，效果很好。但我们需要对这个问题进行更多的解释。也许其他人能帮助我们解决真正的问题。非常感谢。
