MYSQL服務錯誤&無法啟動

我的 MySQL 服務和資料庫似乎在我自己的 VPS 上離線。過去幾個月沒有出現任何問題，所以我不確定是什麼原因造成的。我做的最後一件事是禁用嚴格模式mariadb以使mybb插件正常工作。

這是一個小時前的事，現在資料庫似乎已離線。

我跑了systemctl status mariadb.service，這是輸出：

我的phpmyadmin錯誤是：

#2002 - Connection refused — The server is not responding (or the local server's socket is not correctly configured).

我不確定在我的 debian 伺服器上調試此問題的下一步是什麼。

因為它是 SIGKILL，所以服務很可能會超時，請參閱擴展TimeoutStartSec mariadb 系統文檔
