Question

WordPress droplet 'Error Establishing Database Connection' very often

Hello,

I’ve been having an issue with a WordPress droplet of mine that seems to go down quite often. In each time, when I go to the website I get ‘Error Establishing Database Connection’. The only way for me to resolve this is to restart the server, but it could be days before I realize that the droplet is down and a huge inconvenience. I am looking for guidance or some investigation into how to avoid this or why it is occurring.

Thanks, Marcus

Hi there Marco,

What I could suggest is following the steps from this tutorial here on how to tweak your MySQL configuration for better reliability:

Additionally, I would recommend checking your MySQL error log so that you could get some more information on what might be going wrong. It sounds like the server might be running out of RAM.

If this is the case, I would suggest considering adding a bit of extra RAM and possibly a SWAP file:

Let me know how it goes!

Best,

Bobby
