Upgrading to MariaDB 5.5 on CentOS 6

Installing PHP 5.5 on CentOS 6 using IUS Repositories

I have been inspired once again to fire up my screencasting rig, to show you how to install PHP 5.5 on CentOS 6 using Rackspace’s IUS Community Repositories.

More and more web applications now are likely to require versions of PHP beyond 5.3. CentOS 6 users are stuck with 5.3, with backported security updates, unless they diverge from standard repositories or compile PHP themselves! Until CentOS 7 is with us, those of us trying to run a rock-solid web server on CentOS will be left out in the cold running recent web applications like Moodle 2.7 which require a newer PHP.

In this video, I show you how to use the IUS repositories to get PHP 5.5 running. These repositories, with their Rackspace backing, seem likely to be nice and stable going forward.

As always, I’d love any feedback you might have.

New SleekTabs Video Tutorials

It’s been a while since I last did a video tutorial explaining how to use SleekTabs, so I thought I would dig up the project again and try to explain how to use it a little better.

The result has been my day’s work today. It’s a two part tutorial, showing you how to first set up a simple three-tabbed static web page with Ajax support, and then moving on into part two to show you how to configure fallback support (something that I never touched on previously).

Part 1

Part 2

More info about this tutorial, including the source files for this demo project, and a link to a live working completed version, is available on my documentation wiki.

I am aware that the audio quality is far from good – there is quite bad noise on the audio track and some obvious audio transitions that I really could have done better. However, I still think it’s a good resource for explaining SleekTabs and I’d love to hear any further feedback on either this or the program itself.

What fun you can have by pointing a camera at a monitor displaying the video feed from that camera.

Enjoy.

You can do this with VNC if you’re not lucky enough to have dual monitors. Beware though, you can lock up your system if you use VNC. So save stuff first. 🙂
