I want to install the two or three sites on the same ss codebase, so I follow the instructions of http://www.silverstripe.org/general-questions/show/251650#post251650 and my nginx conf is the same as http://doc.silverstripe.org/doku.php?id=installation-on-nginx. and the fcgi is working well.
After everything mentioned has been done, I visit the url http://mysite.com/, but it's always redirected to http://mysite.com//install.php and it loops.
Did i miss anything? thanks in advance.
