Deploying rails with capistrano + Nginx + Passenger + MYSQL for VPS

This is my first time deploying a rails application and I find the process very frustrating. For work-related reasons, we use the Rackspace cloud with Ubuntu 12.04 LTS (Precise Pangolin) and MYSQL instead of the Heroku route.

I tried to figure this out for 2+ days, and I finally turned to the community for help. I am currently receiving the message "404 Not Found Error on my server"

I followed Ryan Screencasts for "Deployment on VPS", "Capistrano Recipes", this tutorial and others on google, etc. and I'm still not quite there.

I was able to install the following:

  • Node.js
  • RVM
  • ruby 1.9.3p194 (2012-04-20 version 35410) [x86_64-linux]
  • Rails 3.2.8
  • MYSQL
  • Passenger
  • Nginx

I'm sure I missed something simple in my Capistrano Deployer here:

require "bundler/capistrano" server "198.101.242.242", :web, :app, :db, primary: true set :application, "myapp" set :user, "deployer" set :deploy_to, "/home/#{user}/#{application}" set :deploy_via, :remote_cache set :use_sudo, false set :scm, "git" set :repository, " git@github.com :xxxx/#{application}.git" set :branch, "master" default_run_options[:pty] = true ssh_options[:forward_agent] = true # if you want to clean up old releases on each deploy uncomment this: after "deploy", "deploy:cleanup" # if you're still using the script/reaper helper you will need # these http://github.com/rails/irs_process_scripts # If you are using Passenger mod_rails uncomment this: namespace :deploy do task :start do ; end task :stop do ; end task :restart, :roles => :app, :except => { :no_release => true } do run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}" end end

Is there something I have to do before deployment?

Here are the Nginx error logs:

 2012/09/16 23:22:17 [error] 13939#0: *1 "/home/deployer/myapp/public/index.html" is not found (2: No such file or directory), client: ip, server: localhost, request: "GET / HTTP/1.1", host: "ip" 2012/09/16 23:22:17 [error] 13939#0: *1 open() "/home/deployer/myapp/public/favicon.ico" failed (2: No such file or directory), client: ip, server: localhost, request: "GET /favicon.ico HTTP/1.1", host: "65.61.189.109" 2012/09/16 23:22:19 [error] 13939#0: *1 "/home/deployer/myapp/public/index.html" is not found (2: No such file or directory), client: ip, server: localhost, request: "GET / HTTP/1.1", host: "ip" 2012/09/16 23:22:19 [error] 13939#0: *1 open() "/home/deployer/myapp/public/favicon.ico" failed (2: No such file or directory), client: ip, server: localhost, request: "GET /favicon.ico HTTP/1.1", host: "ip"

Ok, so I figured out the problem with trial versions and bugs, as well as from Beef Jerky 's comments.

The first problems were that capistrano was unable to install any stone from my application having dependencies. So I set them up for production ... especially rvm capistrano gem and rmagick. The RVM Capistrano gem was the main problem and the reason I was getting errors when I was depolaring. Rmagick came after fixing the rvm problem that I solved by installing it as dependents.

The second problem I encountered was pointing to my application folder myapp / public instead of the current version of myapp / current / public in the Nginx server configuration file. Therefore, I saved the existing server block and placed my settings inside, and then it worked. Below are the settings for the Nginx server configuration file

 server { listen 80; server_name localhost; root /home/deployer/banking_analytics/current/public; # <--- be sure to point to 'public'! passenger_enabled on; # listen 80; # server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; # location / { # root html; # index index.html index.htm; # } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # # error_page 500 502 503 504 /50x.html; # location = /50x.html { # root html; # } # proxy the PHP s to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP s to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache document root # concurs with nginx one # #location ~ /\.ht { # deny all; #} } # server { # listen 80; # server_name localhost; # location / { # root /home/deployer/banking_analytics/public; # <--- be sure to point to 'public'! # } # passenger_enabled on; # } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443; # server_name localhost; # ssl on; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_timeout 5m; # ssl_protocols SSLv2 SSLv3 TLSv1; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
