紧急求助，重启系统后，mysql无法启动
Starting mysql (via systemctl): mysql.serviceJob for mysql.service failed because the control process exited with error code.See "systemctl status mysql.service" and "journalctl -xe" for details.
failed!
重启了一下系统，结果mysql无法启动了，并且日志是空的。。。
要有日志才行，反馈必读帖子里面有说明
按提示分别执行：systemctl status mysql.service
journalctl -xe
