设备是贝壳云，架构为arm64，使用docker搭建，使用镜像为https://github.com/domenukk/seafile-docker-pi。seafile版本应该是6.3.4.本来已经正常使用一年多，从未出现过问题，因此在里面存了许多重要资料比如论文等。但是现在不知为何突然用mac端的seadrive打开ppt文件时提示服务器内部问题，所以去查看了日志，发现出现无法连接本地服务器的问题。然后尝试重建docker容器，刚搭建完能访问网页，但是涉及数据库的操作比如查看文件，或者进入系统管理就会出错，查看日志发现如下错误：[05/13/2020 04:01:46][upgrade]: The container was recreated, running minor-upgrade.sh to fix the media symlinks,

按照论坛里的建议查看ccnet.conf并不知从何下手，以为面临毕业，里面的论文相关材料需要交给老师。恳请大家帮我，十分感谢。或者只要能恢复里面的数据就好。求好心的大佬帮我看看，不胜感激。
有人帮我看下么 急 真不知可以如何恢复数据 无法下手
看情况是没有链接到数据库没法获取用户信息，确认你的mysql正常，确认seafile ccnet里面关于mysql的信息以及登陆账号密码正确（数据库的管理密码）
请问我该如何排查这个问题呢？需要查看什么文件么。还是需要输入什么命令查看结果呢？我所使用的seafile docker是官方x86版本的fork，作者做了一些修改以适配arm。再部署的过程中并不需要我设定mysql密码啊。我所使用的docker是seafile以及mysql都打包在同一个镜像，是原来官方6.xx版本的方式，不是7.xx版本这种docker-compose方式部署的。请问能提供一些详细点的提示么，让我好下手排查。因为我计算机专业的知识有限，我可能无法解决mysql方面的问题。
先进入docker 中试一下MySQL是否能连接
