Question

我正在运行在Ubuntu 12.04 VPS上托管的rails 3应用程序。我正在使用Capistrano进行部署，使用nginx + unicorn进行部署我的问题是，如果我进行了“上限部署”，我的网站会显示旧代码，直到我重启我的VPS。我检查服务器上的当前代码，它是正确的。我已经尝试重新启动nginx，但它不起作用。我的部署文件（我跟着Railscast）：

# deploy.rb

require "bundler/capistrano"
require 'new_relic/recipes'

server "188.165.145.167", :web, :app, :db, primary: true

set :application, "neurones"
set :user, "neurones"
set :deploy_to, "/home/neurones/apps/#{application}"
set :deploy_via, :remote_cache
set :use_sudo, false
set :shared_children, shared_children + %w{public/uploads}

set :scm, "git"
set :repository, "git@github.com:khcr/neurones.git"
set :branch, "master"

default_run_options[:pty] = true
ssh_options[:forward_agent] = true

after "deploy", "deploy:cleanup" # keep only the last 5 releases
after "deploy:update", "newrelic:notice_deployment" # update new relic

namespace :deploy do
  %w[start stop restart].each do |command|
    desc "#{command} unicorn server"
    task command, roles: :app, except: {no_release: true} do
      run "/etc/init.d/unicorn_#{application} #{command}"
    end
  end

  task :setup_config, roles: :app do
    sudo "ln -nfs #{current_path}/config/nginx.conf /etc/nginx/sites-enabled/#{application}"
    sudo "ln -nfs #{current_path}/config/unicorn_init.sh /etc/init.d/unicorn_#{application}"
    run "mkdir -p #{shared_path}/config"
    put File.read("config/database.example.yml"), "#{shared_path}/config/database.yml"
    puts "Now edit the config files in #{shared_path}."
  end
  after "deploy:setup", "deploy:setup_config"

  task :symlink_config, roles: :app do
    run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
  end
  after "deploy:finalize_update", "deploy:symlink_config"

  desc "Make sure local git is in sync with remote."
  task :check_revision, roles: :web do
    unless `git rev-parse HEAD` == `git rev-parse origin/master`
      puts "WARNING: HEAD is not the same as origin/master"
      puts "Run `git push` to sync changes."
      exit
    end
  end
  before "deploy", "deploy:check_revision"
end

我解决了这个问题。
查看独角兽日志（感谢Domon的想法），我看到了错误：

错误重新加载config_file = / home / neurones / apps / neurones / current / config / unicorn.rb：应用程序已经初始化。（RuntimeError）

我从：

更改了 unicorn_init.sh
restart|reload) sig HUP && echo reloaded OK && exit 0 echo >&2 "Couldn't reload, starting '$CMD' instead" run "$CMD" ;;

以

restart|reload) sig USR2 && echo reloaded OK && exit 0 echo >&2 "Couldn't reload, starting '$CMD' instead" run "$CMD" ;;

使用Capistrano进行部署后需要重新启动
