Deployment 使用capistrano和x2B部署rails；Nginx+；乘客+；MYSQL到VPS

这是我第一次部署rails应用程序，我发现这个过程非常令人沮丧。出于与工作相关的原因，我们将Rackspace云与Ubuntu12.04LTS（精确穿山甲）和MYSQL一起使用，而不是使用Heroku路径

我已经花了两天多的时间试图解决这个问题，我终于向社区寻求帮助。目前我收到一个“404在我的服务器上找不到错误”

我已经关注了Ryan关于“部署到VPS”、“Capistrano菜谱”以及谷歌上其他内容的屏幕广播，但我仍然不太清楚

我设法安装了以下组件：

• Node.js
• RVM
• ruby 1.9.3p194（2012-04-20修订版35410）[x86_64-linux]
• 轨道3.2.8
• MYSQL
• 乘客
• Nginx

我很确定我的Capistrano部署器中缺少了一些简单的东西：

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

部署前我应该做些什么

以下是Nginx错误日志：

第一个问题是capistrano无法从我的应用程序中安装一些具有依赖性的gem。因此，我在生产中安装了这些gem…特别是rvm capistrano gem和rmagick。rvm capistrano gem是主要问题，也是我在卸载时出错的原因。rmagick是在修复了我解决的rvm问题之后出现的通过安装它的从属项

我遇到的第二个问题是指向我的应用文件夹myapp/public，而不是Nginx服务器配置文件中的当前版本myapp/current/public。因此，我保留了现有的服务器块，并将我的设置放在其中，然后它就工作了。以下是Nginx服务器配置文件的设置

root/home/deployer/banking_analytics/current/public；#不久前，我在第一次部署时遇到了类似的错误

在我的例子中，我在mod-http-passer.conf文件中设置了一个错误的路径

我的建议是在nginx设置中启用乘客友好的错误页面，以获取更多错误信息。在某些情况下，它似乎比日志更好

在服务器端

sudo vim /etc/nginx/sites-enabled/myApp

您是否尝试过将应用程序的nginx配置放置在新的服务器块中？我记得我遇到过类似的情况。感谢您的建议，我只是根据您的评论尝试了一下，但没有效果。我不确定“客户端”的用途ip地址在日志文件中。这一点都不正确。我不知道这是从哪里来的。我想这就是你访问网站的地方。你的cap deploy命令是否成功运行？你的绑定器有问题，请检查你的答案和问题是否变得简洁。有没有可能促使你编辑它们以备发布rity？myapp/current/public文件夹从何而来？我只有“myapp/public”Capistrano在部署时应创建/当前/发布和/共享。请检查Capistrano日志
