我有一台装有 ISPConfig 3.1 的 Ubuntu 16.04 服务器。
由于某种原因，服务器在一个高负载的进程上工作过多，所以我关闭电源并重新启动了机器。之后，Mysql 停止工作，无法再重新启动。
我检查了 /var/log/mysql/error.log 的错误日志，但它是空的。
当我尝试重新启动服务时收到以下消息：
Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
systemctl 状态 mysql.service：

但是，在我尝试了这篇文章中的解决方案后，我设法重新启动了该服务：
https://askubuntu.com/questions/1008298/cant-start-mysql-server-database-corruption
所以我设置：
[mysqld]
innodb_force_recovery = 9
但是，由于一些数据库表现在是只读的，所以它不能很好地工作。
我该怎么做呢？谢谢。
