网站关闭 - MariaDB 失败

我有一个工作了两年的网站，突然停止工作了。我没有执行任何更新或升级。当我醒来时，我发现它不起作用。

我联系了我的托管提供商，他们告诉我问题不在于他们。然而，他们帮我检查了这个问题并提供了以下答复：

问题是 MySQL 找不到插件“mysql.plugins”表。升级或更新 MariaDB 后，此问题很常见。

我在 Ubuntu 20 上使用 Cyber​​Panel、OpenLiteSpeed 和 MariaDB。OpenLiteSpeed 显示为活动且正在运行，但 MariaDB 显示为失败。

解决办法是什么？

答案1

DBMS 尝试启动的数据文件已失效。走了。卡普特。

如果你幸运的话，那么你正在从非默认位置（即 /var/lib/mysql 之外）运行 mysqld，并且你现有的配置文件已被覆盖或删除。您只需要修复配置即可。

否则，您需要从备份中恢复。

我没有[备份]

那么你就学到了宝贵的一课。

立即创建备份。

重新安装 Mariadb 可能会起作用。

我正在使用 Cyber​​Panel，

你或许也应该停止这样做。
