In this DigitalOcean article, as a part of a series to help developers with scaling, we will be talking about configuring Varnish with Drupal. This will greatly reduce the amount of time it takes users to load your Drupal based website, and increase t

So I recently setup Varnish on my web servers and it has vastly sped up my sites. However it also broke several things on my Drupal based sites. I ran across this article while trying to kill bugs and it fixed me right up.

Another very quick post for all you aspiring Ubuntu server admins out there. I am not sure how I got along as far as I did without knowing how to easily add a service to the boot time start list or remove it from said list. I already knew how to manually start or stop a service on a running server but I am including those commands just to make this post a bit more complete. This is a short and sweet post (really for my own uses) with an assumption you know more or less what we are trying to accomplish and just need the commands to do it.

As I am now hosting about 8 different sites I was wanting to make restoring from backups a bit easier and less manual. The ultimate goal is to login to my second server and have it up and running with as few key-strokes as possible. Scripting was the answer. It took me several hours of fanangling with syntax in a scratchpad and digging through google to finally put this together. I am sharing my completed work here for anyone else that could possibly make use of it as a spring-board for automating their own restoration process. I just got a new/upgraded backup server so it seemed like a good time to straighten it all out again and streamline things even more.

This is somewhat of a continuation from my earlier posts on automating “off-system” database backups. You can read those posts here:

Setting up automated database backups for your WordPress, Drupal, or Joomla website

Background:

I have two servers. One server is my primary server that hosts all of my live sites.

The second server is a backup server that I pull a copy of my web directory (with sub-directories for each site) and a compressed database dump of each database. (more…)

Owncloud supports several different types of “cache” mechanisms for increasing application performance and, in one particular case, expanding functionality (enabling File Locking).

The two types of caches I am going to discuss today are Redis and APCU. We will start with APCU.

If you have a stand-alone Owncloud installation and just need to optimize for better performance, then APCU is the way to go. It is very simple to get setup, with one small caveat on Ubuntu 14.04 (if you are running the latest LTS distro then this is where you live…).

The PHP5-APCU module is “out of date” relative to what owncloud will accept. So if you just install it with apt and then enable it in your owncloud config file you will get error messages in you logs at best or a more likely just a blank screen when you try to load your site.

So… here is a quick answer on how to fix this issue: (more…)
