Apache's module mod_env offers a handy way of setting environment variables in configuration files, like:
<VirtualHost *:80> ServerName xyz.com DocumentRoot /var/www/rails_app/public PassengerAppRoot /var/www/rails_app SetEnv MY_VARIABLE contents </VirtualHost>
However, in nginx I couldn't find anything that serves the same purpose. What's the alternative here? I thought of setting environment variables in .profile files (I am using Ubuntu 10.04), but that wouldn't have the same "per vHost" isolation I have with Apache, right?
What are the alternatives here?
