mysql - 错误! MariaDB 服务器进程 #{pid} 未运行

Question

MariaDB 10.1.41 在 Mojave MacOS MacBook 上运行。

当我拿起它时 mysql.server启动 一切正常，PID 文件已创建，进程正在运行，允许连接，日志中没有错误，一切正常。

但是当我想用 mysql.server stop 关闭它时，我收到通知: 错误! MariaDB 服务器进程 #28071 未运行! (数字 28071 是撰写此问题时的示例进程 ID)。

日志中仍然没有任何内容，进程仍然处于事件状态(在top/ps等中)，但PID文件消失了

我可以通过kill -15杀死它，但不是这样的。

它工作正常，但在我从备份中恢复机器后(从 Apple 维修服务返回并清理了硬盘驱动器)，它停止了。

我通过使用参数--user解决了同样的问题:

mysql.server status --user=[my_current_user]
