tommcgeeI'm running domain-based, subdomain-based and subdirectory-based sites using the WordPressMu Domain Mapping plugin.
The sites all work, first of all; but the domain name-based ones have a couple of issues:
1) They won't respond to requests without the www prefix. I've got the httpd.conf set up to handle them, I've added both forms of the domain name to the Domains input control. I've also added a * to the A record for the URL.
2) Even while they're working, I'm finding chains of errors for each request, like this:
[Wed Sep 01 15:56:41 2010] [error] [client 10.189.44.250] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace., referer: http://www.virgilofsalzburg.com/

[Wed Sep 01 15:56:41 2010] [error] [client 10.189.44.250] PHP Warning: include_once() [function.include]: Failed opening '/var/www/html/wp-content/sunrise.php' for inclusion (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/wp-includes/ms-settings.php on line 22, referer: http://www.virgilofsalzburg.com/
sunrise.php is of course IN /var/www/html/wp-content, the owner and group are Apache, and it has permissions set to 755.
3) the RSS and ATOM feeds seem to be broken. I can see them in Firefox when I click on the feed icon; I can pull them into my Outlook feed reader; but when I try them through Google Reader or feedvalidator.org they time out.
4) as I'd previously questioned, without getting a solution, only the default permalinks work in domain-based and subdomain-based blogs; any other format breaks and bounces the reader back to the home page.
All of the subdirectory-based blogs work fine.
A couple of URLS:
http://www.icommutetoshu.com
http://www.metroshu.com/
These work, though the non-www versions don't. The feeds are broken when you run them through Google, but you can see them OK in Firefox's default view.
The httpd.conf section for these looks like this:
<VirtualHost *:80>
ServerAdmin mcgeetho@shu.edu
DocumentRoot /var/www/html
ServerName http://www.icommutetoshu.com
ServerAlias icommutetoshu.com
ErrorLog /var/log/icommute-error_log
CustomLog /var/log/icommute-access_log common
</VirtualHost>
I've tried reversing the ServerName and ServerAlias values, to no effect.
On the other hand, http://epirate.shu.edu works in all respects, though "pretty" permalinks are broken.
http://blogs.shu.edu/doit/ works correctly across the board.
