MySQL 自动重启
MySQL Automatically Restarting
问题：
MySQL 在启动后关闭 - 即使在 mysqld 报告 "ready for connections" 之后也是如此。我只是使用公开可用的 mysql 图片。
有谁知道是否有某种设置或错误会导致重新启动？
日志不包含任何表明将要重新启动的错误。重新启动后，数据库似乎工作正常，但我真的很想避免第一次重新启动，因为它把自动化搞得一团糟。

[Note] mysqld: Normal shutdown
这次正常关机后，再次开机，又会报"ready for connections"，之后就好像一直在开机。
显然这是预期的行为，尽管从日志中还不能很清楚地看出这一点。参见 https://github.com/docker-library/mysql/issues/245
我解决这个问题的方法是在尝试连接到数据库之前解析日志以寻找 socket: '/var/run/mysqld/mysqld.sock' port: 3307 MySQL Community Server (GPL) 存在。
我也遇到了这个问题。我能够通过选择 alternate image 来克服它。这为图像添加了健康检查，还提供了一个脚本，当 mysql 准备就绪时，该脚本将 运行。
