从外观上看，我（docker做得很好）搞砸了mysql目录的所有权

如果我运行

ls-la/var/lib/mysql

，它将返回

并使用sudo

sudols-la/var/lib/mysql运行相同的命令

它返回

从外观上看，我（docker确实做到了）成功地更改了mysql目录中所有目录的所有者和组

我需要重新安装MySQL服务器吗？

最简单、最简单的解决方法是什么？

非常感谢你的帮助

更新了修复程序

正如Andy Shinn在第一点中所说，我只是运行了sudo chown-R mysql:mysql/var/lib/mysql更改所有者并启动mysql 通过运行

sudo/etc/init.d/mysql start

返回mysql

mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

[ok]启动mysql（通过systemctl）：mysql.service.

需要更多信息。但我想到两件事

这可能是许可问题。根据您的输出，为什么不首先尝试将所有者和组更改回mysql？这应该是一个简单的

sudochown-rMySQL:mysql/var/lib/mysql

运行

mysql:latest

image可能是您在本地运行的不同版本的mysql，它可能已将mysql数据升级为与旧版本不兼容的新格式。检查您在本地运行的MySQL版本是否与

MySQL:latest

image标记指向的版本相同（至少与次要版本相同，如5.6和5.6）

mysql的最新版本是什么？您在本地运行的是什么版本？您启动的MySQL容器是否有任何日志输出？
