Rough Guide to upgrading WordPress MU 2.9.x to WordPress 3.0 Multi-Site

Posted on by

** Update** Skip to the comments. One Assumption on my part led to a lot more work than is needed. This guide does work, but as Ron (@wpmuguru) pointed out, I went around the block to just go next door. Even smart people are dumb sometimes ;)

The WordPress 3.0 betas are kicking around and for projects still in development, upgrading now will save you the trouble later after the site is in production. Upgrading Single Site WordPress installs to 3.0.x is as easy as ever, but now that WordPress ยต has been rolled into the main WordPress code base it takes a bit more work to “cross-grade” to the new WordPress 3.0 Multi-Site features.

This is a rough guide to upgrading WordPress MU 2.9.x to WordPress 3.0 Multi-Site. That means that I’m largely pulling this from recent memory and may skip a step or state something inaccurately. Feel free to heckle correct me in the comments.

Installing ImageMagick and imagick via MacPorts

Installing ImageMagick with MacPorts couldn’t be easier:


sudo port install ImageMagick

But getting it to work with your PHP installation is a bit harder. If you’ve installed PHP via MacPorts with the pear variant you can install the imagick extension via pecl:


sudo pecl install imagick

The trick to getting it to stop complaining about the Wand-config path, is by passing it the proper prefix for ImageMagick. When prompted, hit 1, then enter in:

/opt/local

Now just add this to the end of your php.ini file, and reboot apache:


[imagemagick]
extension=imagick.so

Installing Sphinx on OS X for PHP

I’m starting to use sphinx in my work, and wanted to get a solid development environment set up for it on my local OS X server. Since I built my local server with Mac Ports, it was actually pretty easy to get that installed:

sudo port install sphinx

However, I had trouble setting up the PHP extension for the Sphinx API. I could have used the sphinxapi.php that ships with the sphinx source code, but having a compiled extension is faster, and I don’t have to add more files to my php project. Installing Sphinx via Mac Ports didn’t help either, because it doesn’t install libsphinxclient, which is required to build the PHP Extension. That was until I found some instructions from someone doing something similar for Ruby.
