我究竟做错了什么？为了在Docker容器内使用配置单元,我还需要做什么？

另外,我看到mysql正在运行

root@7bfa781e1a2c:/opt/hive/conf# ps aux | grep mysql
mysql     1931  0.0  0.0   4624  1768 ?        S    20:19   0:00 /bin/sh /usr/bin/mysqld_safe

> mysql安装随附的默认root用户使用auth_socket作为身份验证插件.这意味着它没有密码.尝试使用mysql -uroot登录,它仍然会登录.

>因此,在mysql中进行任何更改之前,配置单元服务会引发以下错误：

由以下原因引起：java.sql.SQLException：用户’root’@’localhost’的访问被拒绝
