We currently have a linode server set up with following stack :
The Nginx is configured to serve the rails application. However we want to move our wordpress blog to the linode box and have that set up in a subdirectory and configure Nginx to render the wordpress blog.
The wordpress blog files and database dump is already imported to Linode box. Also the PHP and the pear package is also installed on the server. The only thing that is needed is to have the rewrite rules set up properly so that when website is accessed with /blog it should render the wordpress blog.
The Rails developer who set up the whole thing for Rails application will be available to answer any questions to speed up the task. We need to get this done in next 2 - 3 hours.
