Hi, MySQL server is vanished and I don’t know why. Restoring previous (and stable) backups won’t help at all. Running htop command, there are no instances of mysql is shown and service mysql restart gives the following error:
stop: Unknown instance: start: Job failed to start
I checked if it’s installed by apt-get install mysql-server: “mysql-server is already the newest version.” I don’t want to remove and re-install it because I don’t want to lose existing tables.
Command “mysql” gives this error: ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)
Any ideas what might the problem be?

I already have mariadb. The server is up and running, it’s not a memory problem. But suddenly all my databases have disappeared. Any ideas what may be happening? Has DO changed something and the data has gone? All my Wordpress powered databases need some data!
Try adding swap to your droplet: <a href=“https://www.digitalocean.com/community/articles/how-to-add-swap-on-ubuntu-12-04”>https://www.digitalocean.com/community/articles/how-to-add-swap-on-ubuntu-12-04</a>
After a deep research, I found out that mysql.sock file has dissapeared somehow. I couldn’t bring it back no matter what I have tried. <br>Temporary solution: Install mariadb on top of mysql. It fixes the problem.
