用capistrano+Nginx+Passenger+MYSQL部署rails到VPS。

Question

这是我第一次部署rails应用，我发现这个过程非常令人沮丧。由于工作原因，我们使用的是Rackspace云计算，Ubuntu 12.04 LTS（Precise Pangolin）和mysql，而不是Heroku路线。

我已经想了2天多，终于向社区求助。目前我得到的是 "404 Not Found Error on my server"（在我的服务器上找不到错误）。

我关注了Ryan的 "部署到VPS"、"Capistrano Recipes "的屏幕直播。本教程和其他在谷歌等，我仍然没有完全达到。

我设法安装了以下内容。

Node. js
RVM
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
Rails 3.2.8
Rails 3.2.8
乘客
nginx

我很确定我的Capistrano Deployer在这里遗漏了一些简单的东西。

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

在部署前我是否应该做一些事情？

下面是Nginx的错误日志。
