Configuring NGINX to serve Ruby on Rails and Drupal websites

问题

As I try to migrate my Drupal website from Bluehost to DigitalOcean, I am encountering difficulties with my nginx setup.

I have a live Ruby on Rails app living in ~/Kiji and I'd like for the Drupal one to go into ~/EAS.

Here is my current nginx.conf file (which isn't configured as I do not understand exactly what I need to change - I have taken the setup from this page)

worker_processes 1;

events {
worker_connections 1024;
}

http {

passenger_root /home/daniG2k/.rvm/gems/ruby-2.1.2/gems/passenger-4.0.45;
passenger_ruby /home/daniG2k/.rvm/gems/ruby-2.1.2/wrappers/ruby;

include mime.types;
default_type application/octet-stream;
sendfile on;

keepalive_timeout 65;
# Ruby on Rails website
server {
listen 80;
server_name localhost;
passenger_enabled on;
root /home/daniG2k/Kiji/public;

location ~ ^/(assets)/ {
expires max;
add_header Cache-Control public;
gzip_static on;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}

# Drupal website...still working on this~!!
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;

root /usr/share/nginx/html;
index index.php index.html index.htm;

server_name localhost;

location / {
try_files $uri $uri/ =404;
}

error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
}
}

Again, the Drupal part was taken directly from the DigitalOcean website but I am not sure what I need to edit/add here to get it to work. Note, I have already installed MySQL and php5-fpm, php5-mysql.

Any advice is much appreciated!
