Question

我已经通过VirtualBox和Vagrant在macOS Sierra上安装了Homestead。一切正常，除了一些神秘的原因，MySQL在盒子上升超过1分42秒后自行关闭......

我可以在前1分42秒内无问题地使用MySQL，但突然服务关闭并拒绝进一步连接。

服务器出现后我tail编辑/var/log/syslog，并出现以下系统日志条目：

第一行，即mariadb.service，在我被踢出MySQL的那一刻就被记录下来。但我不知道为什么。

看起来日志暗示MySQL / MariaDB仍然试图在盒子启动后启动 - 即使我已经能够在没有问题的情况下连接到它们。然后一些神秘的超时被击中，整个事情就会关闭。

任何人都可以帮我解释这个......？谢谢！

终于弄清楚了 - AppArmor似乎正在引发这个问题。

通过following the steps outlined here，我能够解决问题，并且MySQL不再意外关闭。
