ruby-on-rails - 如何使用 mina 在 Rails 4 应用程序的 deploy.rb 中设置 git？

Question

我正在尝试使用 mina 将我的应用程序部署到 digital ocean 服务器，并在 bitbucket 上有一个 git 存储库。我能够很好地运行 mina setup'，但是当我运行 mina deploy` 时，出现错误。

我的部署.rb

require 'mina/bundler'
require 'mina/rails'
require 'mina/git'
require 'mina/rbenv'  # for rbenv support. (http://rbenv.org)
# require 'mina/rvm'    # for rvm support. (http://rvm.io)

# Basic settings:
#   domain       - The hostname to SSH to.
#   deploy_to    - Path to deploy into.
#   repository   - Git repo to clone from. (needed by mina/git)
#   branch       - Branch name to deploy. (needed by mina/git)

set :rails_env, 'production' 
set :domain, 'my.server'
set :deploy_to, '/home/deployer/mysite'
set :repository, 'git@bitbucket.org:me/myproject.git'
set :branch, 'master'
set :user, 'deployer'
set :forward_agent, true
set :port, '22'


# Manually create these paths in shared/ (eg: shared/config/database.yml) in your server.
# They will be linked in the 'deploy:link_shared_paths' step.
set :shared_paths, ['config/database.yml', 'log', 'config/secrets.yml']

# Optional settings:
#   set :user, 'foobar'    # Username in the server to SSH to.
#   set :port, '30000'     # SSH port number.

# This task is the environment that is loaded for most commands, such as
# `mina deploy` or `mina rake`.
task :environment do
  # If you're using rbenv, use this to load the rbenv environment.
  # Be sure to commit your .rbenv-version to your repository.
  queue %{
    echo "-----> Loading environment"  
    #{echo_cmd %[source ~/.bashrc]}
  }
  invoke :'rbenv:load'

  # For those using RVM, use this to load an RVM version@gemset.
  # invoke :'rvm:use[ruby-1.9.3-p125@default]'
end

# Put any custom mkdir's in here for when `mina setup` is ran.
# For Rails apps, we'll make some of the shared paths that are shared between
# all releases.
task :setup => :environment do
  queue! %[mkdir -p "#{deploy_to}/shared/log"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/shared/log"]

  queue! %[mkdir -p "#{deploy_to}/shared/config"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/shared/config"]

  queue! %[touch "#{deploy_to}/shared/config/database.yml"]
  queue  %[echo "-----> Be sure to edit 'shared/config/database.yml'."]

  queue! %[touch "#{deploy_to}/shared/config/secrets.yml"]
  queue %[echo "-----> Be sure to edit 'shared/config/secrets.yml'."]
end

desc "Deploys the current version to the server."
task :deploy => :environment do
  deploy do
    # Put things that will set up an empty directory into a fully set-up
    # instance of your project.
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'

    to :launch do
      invoke :'passenger:restart'
    end
  end
end

desc "Restarts the nginx server."  
task :restart do  
  invoke :'passenger:restart'
end

namespace :passenger do  
  task :restart do
    queue "mkdir #{deploy_to}/current/tmp; touch #{deploy_to}/current/tmp/restart.txt"
  end
end  

# For help in making your deploy script, see the Mina documentation:

当我执行“mina deploy”时，出现此错误

       Please make sure you have the correct access rights

我在 bitbucket 上设置了 ssh key ，我可以从我的计算机将我的 repo 推送到它，我还在 bitbucket 上设置了一个来 self 的服务器的 ssh key (不确定是否需要它，但我想我会尝试的)。有什么问题吗？

将此添加到您的 deploy.rb 文件中

set :term_mode, nil

确保你已经在github上添加了服务器SSH公钥
