--提前致歉。我不是一个程序员，但在论坛上得到很多热心人士的帮助后，我才走到今天这一步--
我在 GCP 上运行了一个 VM 实例，几年来一直没有出现问题。刚刚收到来自 Google Search Console 的非技术服务器错误消息 (5xx)
重新启动虚拟机 - 但现在消息返回“无法连接到 MySQL：（2002）没有这样的文件或目录错误：”
Ransudo systemctl start mariadb
回复如下：

扫描了网上的资源，发现如下问题：
tc.log（尝试删除/重命名 - 文件上没有任何内容）ntp.drift（不完全确定如何管理这个）
运行 journalctl - 突出显示的行是：

看过问答 https://serverfault.com/questions/1045343/cant-start-mariadb-anymore-on-debian-10
但这似乎并不能解决问题：service mysql restart 产生：
Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.
