Question

Wordpress database error (again and again)

Posted April 20, 2014 2.5k views
I used quick wordpress install (Application > Wordpress on Ubuntu 13.10) Then I used Wp Super cache plugin for caching. When I get huge traffic I got "database error". Then I researched and found swapping. (https://www.digitalocean.com/community/articles/how-to-add-swap-on-ubuntu-12-04) After swapped, everything was fine but today, when I get more traffic again I got "database error" again. I dont know what will I need to do. Can anyone help me?

How big is your droplet? 512MB is usually not enough for a moderately active site running Apache (which is what the 1-click image uses).

You can either upgrade your droplet, or dump Apache in favor of nginx: How To Install Wordpress, Nginx, PHP, and Varnish on Ubuntu 12.04.
How To Install WordPress, Nginx, PHP, and Varnish on Ubuntu 12.04
by Etel Sverdlov
Varnish is an HTTP accelerator and a useful tool for speeding up a server, especially during a times when there is high traffic to a site. It works by redirecting visitors to static pages whenever possible and only drawing on the server itself if there is a need for an active process. This tutorial covers installing wordpress on a LEMP stack (with nginx instead of apache), and then installing varnish.
