deploying an nginx/rails/node app onto EC2

Question

Basic Problem

• I have an app I'm building, and was hoping to get some help deploying it to EC2
• I've been told I should use capistrano
• What are my next steps?

About the App

• simple rails app (3.1.1)
• simple node app (0.4.2)
• redis to communicate between rails and node (2.0.4)
• nginx to reverse proxy both rails and node (1.0.6)
• database is currently sqlite (but will probably upgrade to mysql or mongo in the near future)

• an nginx.conf file is as follows:

  worker_processes  1;
  
  events {
      worker_connections  1024;
  }
  
  http {
    include       mime.types;
    default_type  application/octet-stream;
  
    sendfile        on;
  
    keepalive_timeout  65;
  
    server {
      listen 80;
      server_name localhost;
  
      location / {
        proxy_pass http://localhost:3000/;
      }
  
      location /events/ {
        proxy_pass http://localhost:3001/;
        proxy_buffering off;
        proxy_read_timeout 1000s;
      }
    }
  }
  

About the EC2 instance

• ec2-12-34-56-789.compute-1.amazonaws.com
• Basic 64 bit Amazon Linux t1.micro (until I get everything working, then I'll find some other place to deploy; possibly EC2, possibly rackspace, possibly something completely different)

About my deploying platform

• OSX 10.6.8

• Have the following contents stored in ~/.ec2/ (probably needs to be moved to get capistrano to work)

  cert-123456789ABCDEF0123456789ABCDEF0.pem
  pk-123456789ABCDEF0123456789ABCDEF0.pem
  ec2-keypair
  

• Currently have the following deploy.rb (but it's not working)

  set :application, "clashcentral"
  set :repository,  "git@github.com:HairyMezican/GameLobby.git"
  set :branch, "master"
  set :repository_cache, "git_cache"
  set :deploy_via, :remote_cache
  set :ssh_options, { :forward_agent => true }
  
  set :scm, :git
  ssh_options[:keys] = [File.join(ENV["HOME"], ".ec2", "ec2-keypair")] 
  
  role :web, "ec2-12-34-56-789.compute-1.amazonaws.com"
  role :app, "ec2-12-34-56-789.compute-1.amazonaws.com"
  role :db,  "ec2-12-34-56-789.compute-1.amazonaws.com", :primary => true
  

errors

• The original error I was getting was connection failed for: ec2-12-34-56-789.compute-1.amazonaws.com (Net::SSH::AuthenticationFailed: Empty)
• The current error I am getting, when I added in the line set :user, "ec2-user" is failed: "sh -c 'if [ -d /u/apps/clashcentral/shared/git_cache ]; then cd /u/apps/clashcentral/shared/git_cache && git fetch -q origin && git fetch --tags -q origin && git reset -q --hard cdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcd && git clean -q -d -x -f; else git clone -q git@github.com:HairyMezican/GameLobby.git /u/apps/clashcentral/shared/git_cache && cd /u/apps/clashcentral/shared/git_cache && git checkout -q -b deploy cdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcd; fi'" on ec2-12-34-56-789.compute-1.amazonaws.com

I believe you need to add:

set :user, "ec2-user"

to your deploy.rb file, as seen here: http://wiki.dreamhost.com/Capistrano#Automate_Deployment_with_Capistrano_.28.22capify.22.29
