Getting Started With WPMU and BuddyPress – Part 1: Installing WPMU

With BuddyPress 1.0 due out in a couple of days, there has been no better time to get started with WPMU and BuddyPress! This series of tutorials will teach you the very basics of WPMU and BuddyPress. In this, part one, we’ll be installing WPMU.

Installing WPMU and BuddyPress is something that everyone wants to be able to do, but can’t work out to do. Why? I couldn’t tell you – it’s super easy to do!

Step 1: Get hosted

Hosting hundreds of blogs is quite server intensive; don’t expect to be able to have a massive networks of blogs on budget shared hosting as you’ll very quickly use up too much bandwith and processing power. That said, with guys at WPWebHost have a hosting plan that you can get for $10 that will support upto 100 WPMU blogs, so if you’re serious about starting a small network it might be something to check out.

Step 2: Download, unzip and upload WPMU

First up, head over to and download WPMU. Unzip it and upload it to your server. For this demonstration I’ll be installing WPMU on, so I created a directory /wpmu/ and uploaded all the files to /wpmu/.

Step 3: The database

Once everything is uploaded, head over to the directory you’ve uploaded to and you’ll be greeted with the familiar WordPress install screen. Scroll down a bit and you’ll see some fields and options. The first option is ‘Blog Addresses’. The gives you the option to set where blogs are installed – at or I chose subdirectories just to keep things simple. Next thing to do is enter your database details, which of course you need to set up. Assuming you’re running cPanel, log in and select the ‘MySQL database wizard’. Follow the wizard, selecting ‘all priverlages’ towards the end.

Step 4: The installation

Now the database is set up, return to the installation page we were at a second ago and fill in the database fields with the database we just created. Fill in your email address at the bottom and click install. You’ll then be greated by a ‘sucess’ page and a login link. Login with the password provided and you’ve just installed WPMU!

Step 5: Give yourself a pat on the back

That really was easy, but don’t overdo it; subscribe to the RSS feed to make sure you get part two (and possibly part three) of the series and learn how to get started with BuddyPress. In the meantime, why not have a play around with WPMU? If you use WordPress on your site, it should be a similar experience – in half an hour you can be a WPMU master!
