mysql重启失败

前言

报错：Job for mysqld.service failed because the control process exited with error code. See “systemctl status mysqld.service” and “journalctl -xe” for details.

解决方法

在vim /etc/my.cof最下添加一行下面，重启即为成功

set innodb_force_recovery=1

若重启失败，
把vim /etc/my.cnf

set innodb_force_recovery=0

再次启动，不报错即为成功。
