Symfony2多主机

I have one webhosting with 2 domains. Folder tree is in the image bellow. Where I should put Symfony2 folder? I put them into kozusnikjan.com folder, but it said

Warning: require(/data/web/virtuals/48565/virtual/www/domains/kozusnikjan.com/app/../vendor/autoload.php): failed to open stream: No such file or directory in /data/web/virtuals/48565/virtual/www/domains/kozusnikjan.com/app/autoload.php on line 9

So where I should put them? Thank you

I tried it, but it results in an error:
