Hi :) I followed some tutos and did a search on my issue on google, but no answer found worked for me. I hope you will be able to help me. Here is my configuration : First, I have installed a LAMP for my PHP projects, so apache2 and mysql are correctly installed. I work in the folder : /home/ME/www (where I put my projects) And then, I linked with a symlink my folder /var/www eg: ln -s /home/pixy/www/project1 /var/www/project1 And I have correctly added a vhost (in sites-available, and a2ensite...) This PHP project correctly works on my subdomain : project1.pixy-media.com (don't try, project1 is fake for the example ^^) I also would like to run my Rails (4) applications, so I followed the tuto on Digital Ocean to install passenger with apache2. I think the compilation succeed, I had no problem (I think...) I also put the three lines given at the end of the install at the end of my apache2.conf file Then I put a new project on my workspace : /home/pixy/www/blog I want to access to this application with a vhost, with the subdomain : blog.pixy-media.com I tried a lot of configurations, but no one worked =( I tried to : - symlink /home/pixy/www/blog /var/www/blog and then configure my DocumentRoot to this path : /var/www/blog - No symlink, and directly put the DocumentRoot at /home... And others but I don't remember I pastebin you my actual configurations : - My default vhost : http://pastebin.com/2n7F9mfb - My blog vhost : http://pastebin.com/K3p0WztW I linked as symlink : /home/pixy/www/blog /var/www/rails/blog You can try, it doesn't work... What is wrong/missing with this config ? Do I have to a2ensite the config ? (I think I did it) Do I have to put the PassengerAppRoot ? I work with ruby 2 and rails 4 If you have any question on my config I forgot to tell here ask me. Many thanks in advance for your help ! :)
