Question

MySQL passwords invalid, rebooting droplet fixes it

  • Posted June 11, 2014

I’m running Vesta CP on a droplet.

I’ve noticed that every few weeks (perhaps monthly), all MySQL credentials—including root—become invalid and I get connection errors on all my sites. if I reboot the droplet, everything works again for a few weeks.

Any idea what’s going on here?

As the above answer says, it’s very likely that MySQL is being killed by the OOM killer. That means it is running out of memory. You can confirm this by checking /var/log/syslog after this happens. If that’s the case and it really only is happening every few weeks, you probably don’t need to upgrade to a larger droplet. You can probably get away with just adding some swap to the system. This article should point you in the right direction:
