Running two WordPress installations under one domain

I had the need to maintain two WordPress sites under one domain.  Originally I decided to just have them run in two sub-domains like

• site1.mysite.com
• site2.mysite.com

Later it was requested that the two sites to be run under the same domain like

• http://www.mysite.com (site1 is the default)
• http://www.mysite.com/site2

Here are some notes on how that was done.

1. install two WordPress installations in directories: <home>/www and <home>/www/site2
2. in the /www/site2/.htaccess, you will change the rewrite rules to

   # BEGIN WordPress
   <IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteBase /site2/
   RewriteRule ^index\.php$ – [L]
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule . /site2/index.php [L]
   </IfModule>

3. in addition(assume the old site2.mysite.com is mapped to  <home>/www/oldsite2), add a redirect rule to redirect traffic to old sub-domain.

   RewriteCond %{HTTP_HOST} ^site2\.mysite\.com$ [OR]
   RewriteCond %{HTTP_HOST} ^www\.site2\.mysite\.com$
   RewriteRule ^(.*)$ “http\:\/\/www\.mysite\.com\/site2$1” [R=301,L]
