Question

我正在尝试让capistrano将我的rails应用程序部署到vps。

我登录了vps，添加了一个新的'deployer'用户并通过以下方式给了他sudo权限：

adduser deployer

和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。在我正在使用的gem文件中：

gem 'unicorn'

# Deploy with Capistrano
gem 'capistrano'
gem 'rvm-capistrano', '>= 1.3.0.rc11'

尝试运行cap deploy：setup，我遇到了一堆rvm错误，但通过在cap deploy上重新安装rvm来修复它们：根据capistrano github自述文件，在deploy.rb文件中使用以下命令进行设置：

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，它会很好，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

所以我使用：

将我的'deployer'用户添加到'rvm'组中

sudo usermod -G rvm deployer

运行上限部署后：冷，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

非常感谢任何见解。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 :use_sudo, true
set :keep_releases, 5

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

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

Answer 1

尝试

chown -R deployer /home/deployer

Answer 2

确保所有文件夹归部署者所有。：）
