Question

我遇到了MariaDB的问题，而它首先正常工作。当我无法再启动MySQL守护进程时，我只重新启动了服务器。它似乎仍在使用旧的USB-stick文件路径（/ media / brood），而我已经切换到新的硬盘（/ media / seagate）。这是我在/var/log/mysql/error.log中遇到的错误：

它也可能是权限问题，或者文件仍然被锁定（我不知道它是如何工作的），因为Raspberry Pi最后一次重启，这是因为有人意外拔出了电源插头裨。

为什么日志包含旧mysql数据文件夹的路径对我来说仍然是个谜。（它甚至不是以前的USB棒，为了使故事更完整，它实际上是我之前使用的USB棒！）但是，问题解决了！答案实际上很多比我想象的更简单，事实证明，我的兄弟卸载了一些东西（一个用于玩旧游戏的模拟器，他说），当他注意到它卸载了mariadb-server-10.0（奇怪！）。所以我做了一个简单的sudo apt-get install mariadb-server-10.0，猜猜是什么！它解决了我的问题！：d
