SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

Posted on July 16, 2017

Dear Team, I have two droplets on Digitalocean with same configuration on UBUNTU platform. 1 is performing great, but facing DB issue in another one.

In every 2-3 months, MYSQL DB is getting down with error- SQLSTATE[HY000] [2002] Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’

TO solve this issue I followed thread https://www.digitalocean.com/community/questions/magento-shows-error-sqlstate-hy000-2002-can-t-connect-to-local-mysql-server-through-socket-var-run-mysqld-mysqld-sock-13.

But again after some months same issue is happening again and again. Please guide me how to avoid from getting DB down?

Hi @maneeshpatel198

Are you running Magento? Then you’re most likely running out of memory and because MySQL is the biggest consumer of memory on your system, then it’s being crashed, so the entire system doesn’t crash. How much memory do you have on the droplet, which has the problem?
