我正在尝试让 capistrano 将我的 rails 应用程序部署到 vps。
我登录到 vps，添加了一个新的“部署者”用户，并通过以下方式给了他 sudo 权限：
adduser deployer
并在 visudo
deployer ALL=(ALL:ALL) ALL
我安装了 rvm、ruby、postgres、postfix 和 nginx。全部使用 apt-get，最新版本的 ruby 和 rvm。在我的 gem 文件中，我正在使用：
gem 'unicorn'
# Deploy with Capistrano
gem 'capistrano'
gem 'rvm-capistrano', '>= 1.3.0.rc11'
根据 capistrano github 自述文件，尝试运行 cap deploy:setup 时，我遇到了一堆 rvm 错误，但通过在我的 deploy.rb 文件中使用以下内容在 cap deploy:setup 上重新安装 rvm 来修复它们：
set :rvm_ruby_string, 'ruby-1.9.3-p392' # use the same ruby as used locally for deployment
set :rvm_install_ruby_params, '--1.9' # for jruby/rbx default to 1.9 mode
set :rvm_install_pkgs, %w[libyaml openssl] # package list from https://rvm.io/packages
set :rvm_install_ruby_params, '--with-opt-dir=/usr/local/rvm/usr' # package support
before 'deploy:setup', 'rvm:install_rvm' # install RVM
before 'deploy:setup', 'rvm:install_pkgs' # install RVM packages before Ruby
before 'deploy:setup', 'rvm:install_ruby' # install Ruby and create gemset, or:
before 'deploy:setup', 'rvm:create_gemset' # only create gemset
before 'deploy:setup', 'rvm:import_gemset' # import gemset from file
当我运行 cap deploy:cold 时，它运行良好，直到它给出错误的结尾：
failed: "rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell 'ruby-1.9.3-p392' -c 'cd /home/deployer/apps/blog/releases/20130301223924 && bundle install --gemfile /home/deployer/apps/blog/releases/20130301223924/Gemfile --path /home/deployer/apps/blog/shared/bundle --deployment --quiet --without development test'" on 198.211.127.46
因此，我使用以下命令将我的“部署者”用户添加到“rvm”组中：
sudo usermod -G rvm deployer
运行 cap deploy:cold 后，得到错误：
** [out :: 198.211.127.46] cannot create directory `/home/deployer/apps/blog/releases/20130301223718'
** [out :: 198.211.127.46] : Permission denied
任何见解将不胜感激。我快到了。
这是我的 deploy.rb 文件：
require "bundler/capistrano"
require "rvm/capistrano"
server "198.211.127.46", :web, :app, :db, primary: true
set :port, 46000
set :application, "blog"
set :user, "deployer"
set :deploy_to, "/home/#{user}/apps/#{application}"
set :deploy_via, :remote_cache

set :keep_releases, 5
set :scm, "git"
set :repository, "git@bitbucket.org:myusername/#{application}.git"
set :branch, "master"
