I deployed my first rails project following deploying-a-rails-app-on-ubuntu-14-04-with-capistrano-nginx-and-puma
after lot of issues, I completed all the steps almost in 4 days.
But now when I point my web browser to my server IP it say
An unhandled lowlevel error occurred. The application logs may have details.
whats the issue now and how to see application logs ?
You need to look in your app directory logs for puma or webserver. I just had this and found this message:
Rack app error: #<RuntimeError: Missing `secret_token` and `secret_key_base` for ‘production’ environment, set these values in `config/secrets.yml`>
I have a dedicated DreamHost Server where I installed a ruby on rails app under /srv directory, I installed nginx with passenger and configured nginx to open my app when I access my domain which is the server name .dreamhost.com. However, it is still showing welcome to nginx page even if I run sudo /etc/init.d/nginx reload or stop or service nginx stop I get no error but nothing changes and I keep getting the welcome page as if the restart or stop didn't take any effect. Also I tried to remove nginx but nothing changed. This is my /etc/nginx/nginx.conf file: ``` user www-data; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "msie6"; # gzip_vary on; # gzip_proxied any; # gzip_comp_level 6; # gzip_buffers 16 8k; # gzip_http_version 1.1; # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; ## # nginx-naxsi config ## # Uncomment it if you installed nginx-naxsi ## #include /etc/nginx/naxsi_core.rules; ## # nginx-passenger config ## # Uncomment it if you installed nginx-passenger ## passenger_root /home/madrasati/.rvm/gems/ruby-1.8.7-head/gems/passenger-5.1.2; passenger_ruby /home/madrasati/.rvm/gems/ruby-1.8.7-head/wrappers/ruby; # include /etc/nginx/passenger.conf; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } #mail { # # See sample authentication script at: # # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript # # # auth_http localhost/auth.php; # # pop3_capabilities "TOP" "USER"; # # imap_capabilities "IMAP4rev1" "UIDPLUS"; # # server { # listen localhost:110; # protocol pop3; # proxy on; # } # # server { # listen localhost:143; # protocol imap; # proxy on; # } #} ``` This is etc/nginx/sites-available/myapp file ``` server { listen 80 default_server; server_name www.madrasatie.com *.madrasatie.com ds10316.dreamservers.com; passenger_enabled on; passenger_app_env production; root /srv/fedena_app/fedena_cds/public; } ``` And this is /home/madrasatie/nginx/madrasatie: ``` server { listen 80 default_server; server_name www.madrasatie.com *.madrasatie.com *.208.97.137.194; passenger_enabled on; passenger_app_env production; root /srv/fedena_app/fedena_cds/public; } ``` I tried so many things and nothing is taking effect. Please help me solve this.

I can't figure out how to configure properly nginx and puma in my ruby on rails application. When a access it in the browser I get a 502. I see many similar files: - /etc/nginx/nginx.conf - /etc/nginx/sites-enabled/myapp - /etc/nginx/sites-enabled/myapp_production - /etc/nginx/sites-avaliable/myapp_production - ~/apps/me/current/config/ngnix.conf Do I really need that file `config/nginx.conf` inside my application? How do sockets are supposed to be configured and work? Is there a file among these I mentioned I don`t really need? If Nginx was working/configured properly it should show this file `/var/www/html/index.nginx-debian.html` ? If you need any additional information to be able to help me I'll gladly provide it. Thanks in advance, Diego
I am trying to use the instructions at http://jrochelly.com/post/2013/08/nginx-unicorn-multiple-rails-apps/ to setup the sub uri (www.mydomain.com/site1 www.mydomain.com/site2) based Rails applications using Nginx and Unicorn. I started with Droplet that had Unicorn and Nginx pre-installed from DO and it works fine. Now I want to setup multiple sites/Rails apps based on Sub uri. As per the instructions I have updated nginx.conf by adding follwoing to current nginx.conf ``` upstream unicorn_socket_for_site2 { server unix:/home/navjeetc/site2/current/tmp/sockets/unicorn.sock fail_timeout=0; } ``` Then I created a file site2 under sites-enabled as below: ``` server { location /site2/ { try_files $uri @unicorn_proxy; } location @unicorn_proxy { proxy_pass http://unix:/home/navjeetc/site2/current/tmp/sockets/unicorn.sock; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Forwarded-Proto $scheme; } } ``` And then made changes to my site2 Rails app as suggested. I did not change unicorn conf file. But the request to http:/subdomain.mydomain.com/site2 is still going to the old Rails app and I get a 404. The nginx config file for the old Rails app is: ``` server { listen 80; root /home/rails/current/public; server_name _; index index.htm index.html; location / { try_files $uri/index.html $uri.html $uri @app; } location ~* ^.+\.(jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mp3|flv|mpeg|avi)$ { try_files $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_server; } } ``` How can I fix this?
A few places to look are:
