因为我不知道在另一个问题中提问是否合适，所以我开了一个新的问题 - 我可能遇到与这里相同的问题：mysql 服务器每 30 秒重启一次
但是：我的 MaSQL 没有记录配置错误（事实上，我认为配置中确实出了问题，因为他根本没有记录。但他启动了（我可以连接/使用它），但服务器变得非常慢，过了一段时间，他不再响应，必须进行硬重置。
有人能帮我检查一下配置文件吗？我会把它放在下面——不过知道了：这是一个多实例设置。至少实例 2 有这个问题

答案1
看来我找到原因了……
这是软件包的初始化脚本。由于我将默认设置更改为多设置，因此我使用自己的脚本来停止和启动这两个实例。但看起来软件包更新激活了默认的初始化脚本，而该脚本不适用于我的设置。所以我再次将其停用：
service mysql stop
update-rc.d -f mysql remove
从那时起，系统日志就不再充满重生消息了。现在我继续寻找没有记录任何内容的原因 ;-)
无论如何，感谢您的帮助！
答案2
在我的系统上（10.10 运行 mysqld_multi），/etc/init/ 下有一个 mysql.conf 脚本，我必须删除它才能解决错误。不太清楚它是如何/为什么会出现在那里的，但它确实在执行相同的重生
