要么是我瞎了，要么就是没有任何错误，mariadb就是不工作。也许你们当中有人有个主意。谢谢

编辑：

我找到了一个“解决方案”，因为启动时超时，mariadb正在关闭，所以现在我将超时设置为0。目前，这个解决方案已经足够，但必须有一个真正的解决方案。

请注意，自10.1.10以来，MariaDB使用systemd启动服务。不再使用/etc/init.d/mysql脚本，因此MYSQLD_STARTUP_TIMEOUT无效

您需要找到mariadb.service文件。在我们的例子中，它不包含超时，因此使用了MariaDB默认值。只需添加

/etc/systemd/system/mariadb.service.d/override.conf

文件，并将其放入：

[Service]
TimeoutStartSec = 0

在[服务]部分，它将永远不会超时。创建文件后：

# systemctl daemon-reload
# systemctl restart mysql.service

3306端口可用吗？也许您可以检查一下，是否有其他应用程序正在侦听此端口。端口可用，如我的编辑中所述，由于启动时超时，mariadb正在启动并再次关闭。现在，通过将超时设置为0，它将不再关闭，但这不是一个“真正的”解决方案，或者？
