Drupal and MySQL Performance: Register now for Nov. 13 webinar

Drupal is one of the most popular open source CMS applications available – and it runs primarily on a MySQL backend.  Out of the box, the schema is well tuned and indexed.  However, there are some ways to tweak the default installation to get more out of the system right from start.  Similarly, there is a fair bit of hidden flexibility (especially in the latest version) in terms of database configuration.

In a free MySQL webinar on Wednesday, November 13th at 1pm EST, I’ll go over some of the improvements in Drupal 7 in terms of database connectivity and operation as well as profile the default installation from the database perspective.  I’ll also be covering some of the ways to optimize the default application and detailing some of the ways to benchmark your installation.

The title …

Trip Report: DrupalCon Portland 2013

I have never been to a DrupalCon before so my first was DrupalCon Portland 2013 (with some 3,500+ attendees). My first DrupalCon happened to also be one that I spoke at, and I hope to return to Austin in 2014 (added bonus: I’ve never been to Texas before).

SkySQL had decided to get a booth at DrupalCon since I was speaking and I have to say that the booth was very successful. You may ask why and the simple reasons are:

  1. Everyone at DrupalCon was a user of MySQL. Once they hit scale, they may need professional services or even just switch to MariaDB. This is a captive audience.
  2. Everyone running Drupal at scale with many modules and nodes generally faced issues with database slowdowns. Hello …

High Availability for Drupal Part 1 - Investigating the Issues

Drupal is one of the most popular Content Management Systems (CMS) and is used increasingly in high-visibility sites, such as www.whitehouse.gov. This has brought a lot of attention on how to get the most performance out of Drupal and how to improve the availability of such sites. In this blog series I'll take you through the basics and on through to designing your own HA Drupal site.

But first, we need to understand what the challenges are in getting Drupal (or indeed any CMS) working on multiple servers in such a way as to ensure high availability and performance.

Keeping your Drupal from Drooping — part 2

So let’s clone our current Drupal 7.22 site from MySQL 5.1 that came with CentOS 6.4 and get it running on MySQL 5.6.

Upgrading MySQL 5.1 -> 5.6 has an official recommendation of making sure the intermediate 5.5 update is performed too. Please review Section 2.11.1 while you make a backup of all your data. Yes, you do have to make a backup. When you run the upgrade, there are tables in the mysql scehma that will be tweaked and skipping a step can make for a very messy late night in an attempt to recover.

An other thing to look for is that on occasion new reserved words are introduced that may conflict with column names in use in your schemas. So it pays to read through the release notes for new reserved words and then run a quick grep on your tables to be safe. If you find that there is a new reserved word …

Keeping your Drupal from Drooping — part 1

This is the first screen after a sucessful Drupal 7.22 install.

Drupal is a content management system that runs at least 2.1% of all websites(1). It is easy to use, extensable with over 20,000 add-ons, and runs beautifully with a LAMP stack.

At the heart of most Drupal sites is a MySQL database with, as of Version 7.22, 76 tables. Recently I was asked what needs to be done to a ‘generic’ Drupal to get it running on MySQL 5.6. It is a very easy update that provides better performance, security, and allows access to the newest MySQL 5.6 updates.

For this example, the generic box is a two CPU Dell x86_64 box running Centos 6.4. This is fairly typical of what a low-end hosted system from one of the many web hosting businesses a small busines might rent. Centos 6.4 was installed.

Now to use Yum to get the with the …
