Cap中止！rvm:部署期间检查中断(Cap3)

Question

通过Capistrano 3部署rails应用程序(Rails -v 3.2.12)

$ bundle exec cap production deploy --trace

并面临以下几个问题：

** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke production (first_time)
** Invoke bundler:map_bins (first_time)
** Execute bundler:map_bins
** Invoke deploy (first_time)
** Invoke git:deploy (first_time)
** Execute git:deploy
** Execute deploy
** Invoke deploy:starting (first_time)
** Execute deploy:starting
** Invoke deploy:check (first_time)
** Execute deploy:check
** Invoke git:check (first_time)
** Invoke git:wrapper (first_time)
** Execute git:wrapper

The deploy has failed with an error: #<Net::SSH::AuthenticationFailed: user>

Capfile：

require 'capistrano/setup'
require 'capistrano/deploy'
#require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails'

注:我注释掉了'capistrano/rvm‘。当它未被注释时，我将面临以下输出：

** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke rvm:hook (first_time)

cap aborted!
Net::SSH::AuthenticationFailed: user

因此，两个版本都以错误结尾

以下是我的设置：

deploy.rb

set :repo_url, 'git@bitbucket.org:user/project.git'
set :application, 'project'
application = 'project'
set :rvm_type, :system
set :rvm_ruby_version, '2.0.0-p353'
set :deploy_to, '/var/www/apps/project'
set :user, 'user'
set :ssh_options, {
  #verbose: :debug,
  user: fetch(:user)
}

deploy/production.rb

server '111.111.111.111', user: 'user', roles: %w{web app db}, my_property: :my_value

set :ssh_options, { 
forward_agent: false,
}

那到底是怎么回事？请帮帮忙

Answer 1

尝试在deploy/production.rb中提供更具体的设置，如下所示：

set :ssh_options, {
  user: 'user',
  keys:  [File.join(ENV["HOME"], ".ssh", "deploy_key")],
  forward_agent: false,
  paranoid: false,
  auth_methods: %w(publickey)
}
