mysql database disappeared

Hello Observium Team ,

I had a power outage at home and my Observium VM (ubuntu 22.04) running on my server was shut down unexpectedly. I can log back in to my observium server but mysql database is not starting up. "Error 2002 HY000 Cant connect to local mysql server through socket var run  mysql". Please assist an d let me know if mysql should be re-installed. 

Thank  you
