Nginx and Unicorn Multiple Rails apps

For each app, you need to make sure unicorn is listening on a different socket. In the app’s <code>config/unicorn.rb</code>, change the socket value to be unique: <pre> listen “/tmp/unicorn.app_one.sock” </pre> Then in the Nginx configuration, you’ll need a new server block for each app. It will look something like: <pre> upstream app_one { # Path to Unicorn SOCK file, as defined previously server unix:/tmp/unicorn.app_one.sock fail_timeout=0; }

upstream app_two { server unix:/tmp/unicorn.app_two.sock fail_timeout=0; }

server { listen 80; server_name domain-for-app_one.com;

# Application root, as defined previously
root /root/app_one/public;

try_files $uri/index.html $uri @app;

location @app {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://app_one;
}

error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;

}

server { listen 80; server_name domain-for-app_two.com;

# Application root, as defined previously
root /root/app_two/public;

try_files $uri/index.html $uri @app;

location @app {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://app_two;
}

error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;

}
</pre>

Have your tried VirtualHosts? With properly setup you can have different domains/folder.
