mysql启动不了也可能是数据盘满了
一位站长说数据库打不开，提示如下:Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.
翻译后的意思如下：
mysqld.service的作业失败，因为控制进程退出，返回错误代码。有关详细信息，请参阅“systemctl status mysqld.service”和“journalctl-xe”。
从提示来看应该是空间满了，站长也发来了磁盘存储明细：

站长说清理了还是一样打不开
