Today I decided to setup a vagrant box and play with Yii2. It’s RC so I thought it’s time to be in the game 
First the issue:
I setup dns for frontend (FE) and backend(BE) via nginx. In any case I only got backend rendered no matter which domain I used, which is very strange. Now read on for the interesting part!
Tech details:
I brought up a vagrant box and installed yii2-advanced project. Vagrant is a base Ubuntu 12.04 box with nginx & php-fpm. I had two nginx server hosts for frontend and backend. I checked both configs about 1 million times they are correct. I had two subdomains:
fe.localhost.com & be.localhost.com respectively to render FE and BE. Id doesn’t matter which one I use yii always renders backend . So I decided to rename the BE folder to backend_ (note the underscore after backend!). Interestingly I got an error in the error log:
2014/10/17 14:33:03 [error] 3698#0: *325 FastCGI sent in stderr: "PHP message: PHP Warning: require(/usr/share/nginx/www/yii2/backend/web/../config/bootstrap.php): failed to open stream: No such file or directory in /usr/share/nginx/www/yii2/frontend/web/index.php on line 8
PHP message: PHP Stack trace:

PHP message: PHP Stack trace:

the error suggests there is a problem with line 8 in frontend/web/index.php which is line:
require(__DIR__ . '/../config/bootstrap.php');
so I commented this line and all started working again. So without this line FE & BE are rendered without any issue. It could of course be something with vagrant but I tested with two simple files (frontend.php & backend.php) and they both were rendered correctly, which makes me think no issue in vagrant/nginx.
