Question

我正在修改一个功能性的Capistrano脚本试图加快速度，因为我的家庭上网速度非常可怕。我有一个git服务器（不是github）和一个ubuntu开发服务器，当我运行cap部署时，它当前从我的git repo抓取最新的并制作本地副本然后将其上传到我的ubuntu服务器并重新启动乘客而没有问题。我的capistrano代码包含...

set :deploy_via, :copy

但如果我尝试使用它......

set :deploy_via, :remote_cache

我收到此错误...

提示输入git密码 - gitadmin@sub.example.com' s密码：

我输入

然后它继续正常，然后它似乎在上面的下一个命令出错。我猜我需要以某种方式设置一些ssh密钥？同样，这不是托管在github上，repo和dev服务器是我公司服务器上的两个独立的盒子。本地我正在运行Windows 7.如果我尝试添加...

set :ssh_options, { :forward_agent => true }
default_run_options[:pty] = true

我得到相同的距离，但这次不是自动说拒绝权限，而是提示输入gitadmin密码，我输入正确的密码，然后说'＃34;权限被拒绝＆＃34;。

如果您发布了完整的capistrano scipt（减去任何密码，IP地址）会有所帮助，但我怀疑您需要将您的服务器引入远程存储库。您根本不需要deploy_via选项

要将您的服务器引入您的repo ssh到您的服务器，并从那里ssh到存储库服务，应该有用于此的URL的文档。您将收到拒绝访问的消息，但关键是此进程将ssh公钥添加到您的服务器

在部署时可能还值得观看Ryan Bates Railscast，他使用github，但任何远程仓库的过程都非常相似

http://railscasts.com/episodes/335-deploying-to-a-vps 注意他如何将他的服务器引入github，就像我说的那样，你的服务应该为你提供类似介绍的说明

有一个修改过的（专业）演员阵容需要订阅，但Ryan正处于延长休息时间（可能现在无限期），因此订阅将是非常有价值的，值得考虑。

关于capstrano的修订（专业）演员，如何设置变量等......在这里http://railscasts.com/episodes/133-capistrano-tasks-revised

这是我的一个应用程序的工作脚本，只需根据您的需要替换xxx和路径，我假设您已经设置了所有启动和重新启动的东西，但这应该指向您至少所需的最低设置。我这样说是因为你可能有其他你不需要的设置，但由于你还没有发布你的脚本，所以无法分辨。

require "bundler/capistrano"

server "146.185.182.228", :web, :app, :db, primary: true
set :application, "xxx"
set :user, "xxxx"

# adjust if you are using RVM, remove if you are not
set :rvm_type, :user
set :rvm_ruby_string, 'ruby-2.0.0-p353'
set :ssh_options, {:forward_agent => true}

default_run_options[:pty] = true


# file paths
set :repository, "git@bitbucket.org:xxxx.git"
set :deploy_to, "/home/#{user}/apps/#{application}"
# set :scm, :git # You can set :scm explicitly or Capistrano will make an intelligent guess based on known version control directory names
# Or: `accurev`, `bzr`, `cvs`, `darcs`, `git`, `mercurial`, `perforce`, `subversion` or `none`
set :scm, :git
set :use_sudo, false
set :rails_env, :production
set :password, "xxxxxxx"

#role :web, "your web-server here"                          # Your HTTP server, Apache/etc
#role :app, "your app-server here"                          # This may be the same as your `Web` server
#role :db,  "your primary db-server here", :primary => true # This is where Rails migrations will run
#role :db,  "your slave db-server here"

# if you want to clean up old releases on each deploy uncomment this:
after "deploy:restart", "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
  %w[start stop restart].each do |command|
    desc "#{command} unicorn server"
    task command, roles: :app, except: {no_release: true} do
      run "cd #{release_path} && bundle install"
      run "/etc/init.d/unicorn_#{application} #{command}"
      run "#{sudo} service nginx #{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/init_unicorn.sh /etc/init.d/unicorn_#{application}"
    sudo "ln -nfs #{current_path}/config/sidekiq.conf /etc/init/sidekiq.conf"
    run "mkdir -p #{shared_path}/config"
  end
  after "deploy:setup", "deploy:setup_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"
  after "deploy:update_code", "deploy:symlink_shared"

end

使用remote_cache进行Capistrano部署 - 权限被拒绝
