Wordpress MU Virtual Host File

Note that for the wordpress MU the Server Alias is a wildcard domain, this allows for on the fly creation of subdomain blogs

 <VirtualHost *>
        ServerAdmin youremail@domain.com
        ServerName  domain.com
        ServerAlias *.domain.com

        # Indexes + Directory Root.
        DirectoryIndex index.php
        DocumentRoot /var/www/wordpress-mu/

        # CGI Directory
        #ScriptAlias /cgi-bin/ /home/www/www.example.com/cgi-bin/
        #<Location /cgi-bin>
        #        Options +ExecCGI
        #</Location>


        # Logfiles
        ErrorLog  /var/www/wordpress-mu/logs/error.log
        CustomLog /var/www/wordpress-mu/logs/access.log combined

   <Directory /var/www/wordpress-mu/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride FileInfo Options
                Order allow,deny
                allow from all
        </Directory>


</VirtualHost>

Once I got the virtual hosts in place I enabled the sites by invoking each file name as follows:

a2ensite wordpressmu
a2ensite prestashop

Once I had the sites enabled I renamed the wordpress site to 000-wordpressmu so that it would load first, long story short this took me a lot of time to resolve. Once I renamed it (by invoking the move command) then I reloaded apache and confirmed that the sites were accessible by their domains. Note that I setup the domains on an external service and pointed the A record at the server.

Once this was set then I went through and installed Deki and enabled its virtualhost file too.  

Note2: Check your ports.conf file and make sure that the NameVirtualHost line has just * as opposed to *:80, this needs to match the top of you virtual host files otherwise apache will complain and there will be resolution issues. 

 I reloaded Apache and everything resolved. 

Note that the Virtualhost file for Deki was installed automatically.  MindTouch Deki is sooo easy to install.
