Question

我想用capistrano部署我的项目。这是我的设置文件：

deploy.rb

require "capistrano/ext/multistage"
require "capistrano_colors"
require "bundler/capistrano"

require "rvm/capistrano"                       # Load RVM"s capistrano plugin.

set :application, "project"
set :copy_exclude, %w(.git .gitignore doc features log spec test tmp Capfile)
#set :shared_children, shared_children + %w(public/uploads)

set :use_sudo, false
set :user, "app"

set :stages, %w(staging production)

namespace :deploy do
  task :start, roles: :app, except: { no_release: true } do
    run "cd #{current_path} && bundle exec unicorn_rails -c config/unicorn.rb -E #{rails_env} -D"
  end

  task :stop, roles: :app, except: { no_release: true } do
    run "kill -KILL -s QUIT `cat #{shared_path}/pids/unicorn.pid`"
  end

  task :restart, roles: :app, except: { no_release: true } do
    stop
    start
  end
end

def confirm
  puts "\n\e[0;36m#{stage}\e[0m\e[0;31m Do you really deploy? (yes/no) \e[0m\n"
  proceed = STDIN.gets rescue nil
  exit unless proceed.chomp! == "yes"
end

对于多级，我创建了两个文件（一个是环境）：部署/ production.rb

server "myserver.net", :app, :web, :db, primary: true
set :rails_env, "production"

set :rvm_type, :user
set :rvm_ruby_string, "ruby-2.0.0-p0"

set :scm, :git
set :repository, 'ssh://xxxx@11.111.111.111:54333/~/git-workspace/myproject.git'
set :deploy_via, :remote_cache

confirm

和暂存的几乎相同。

（正如您所猜测的那样，出于安全考虑，我已更改了项目，服务器名称和端口号）

我第一次执行：

捆绑exe cap生产部署：检查

然后：

没有任何问题，在调用deploy命令（bundle exe cap production deploy）时，我收到以下消息：

我已生成密钥（在我的本地环境中）并将公共密钥放在authorized_keys文件（服务器端）中。

您似乎采取了许多正确的步骤，所以现在出现这种错误，您应该直接测试权限：

确保您可以从开发计算机（运行capistrano的位置）ssh到该用户的部署服务器。（例如，这可能与ssh deploy@myserver.com。
一旦确定可行，然后在登录服务器时，作为部署用户，请尝试连接到存储库服务器。例如，ssh -T git@github.com as described here。

99％的时间，如果你能成功完成这两件事，就没有权限问题。
