The instructions for getting Wordpress MU to play nice on a Linux server are for the most part very good, but they do miss 1 important step when configure a Wordpress MU (and soon to be Wordpress 3.0) site on a Linux/Plesk web server.

I’m assuming you’ve already configured the wildcard CNAME (*.yourdomain.com) record in your sites DNS settings.

Once you have done that, log into your server as root (either directly or sudo user) and navigate to /var/www/vhosts/yourdomain.com /conf (replace yourdomain.com). You will have to be root or a sudo user to access this folder.

Then we get out our trusty text editor

vi vhosts.conf

Now add the following to the empty document (if the document already exists, check to make sure that the below rule is not in their and then add to the end of the file)

ServerAlias *.yourdomain.com

Now all that needs to be done is

/usr/local/psa/admin/sbin/websrvmng --reconfigure-vhost --vhost-name=yourdomain.com

There you have it. If you have correctly configured each and every other step outlined in the WordpressMu FAQ then you’ll be right as rain!.

Update: I forgot to mention that you need to have “Custom Error Documents” turned on. To do this in plesk, Navigate to your domains hosting page, click on “Setup” under Hosting. Scroll down to Services and select “Custom Error Documents” and then click ok.

I’m going to step you through how I went about installing Nathan Moinvaziri’s plugin and set up Wordpress 2.2 to use Permalinks in an IIS6 enviroment with Plesk 8 installed.NOTE: This worked for me, and my hosting environment. I have no idea if it will work for everyone. I will not be held responsible for any damage you do to your blog. You have been warned.

Configure Plesk

Log into Plesk

Navigate to your domains control page.

Click on the icon “Web Directories”

Click on the tab “Error Documents”

Locate the entrie that reads “404 Not Found” and click on it. You may need to navigate to the next page to see it.

Drop down the “Type” box and select “URL”

In the “Location Box” type “/” (Without the quotation marks)

Click “Ok”

Log out of Plesk

Visit “http://www.nathanm.com/myprojects/#plugin” (opens in a new window)

Find the Plugin “Wordpress - Remove Index.php from Permalinks in IIS Plugin”

Upload the php file “removeindex.php” to your wordpress plugins directory
Log into Wordpress admin.
Click on “Plugins”

Locate the “Remove index.php” plugin and click on “Activate”

Click on “Options” then “Permalinks”

Set your Permalinks Structure. First click one of the common options. Then click on the “Custom, specify below” box and remove “index.php”. I use /%year%/%category%/%postname%/ for my structure.

Click “Update Permalinks Structure”

And your done :D

Check to make sure that everything is working. If you have sitemaps, it’s best to re generate them and submit them to google. The old ?p=34 strings will still work though. Test everything.
